SEIS 665 Assignment 2: Linux & Git Overview This week we will focus on becoming familiar with launching a Linux server and working with some basic Linux and Git commands. We will use AWS to launch and host the Linux server. AWS might seem a little confusing at this point. Don’t worry, we will gain much more hands-on experience with AWS throughout the course. The goal is to get you comfortable working with the technology and not overwhelm you with all the details. Requirements You need to have a personal AWS account and GitHub account for this assignment. You should also read the Git Hands-on Guide and Linux Hands-on Guide before beginning this exercise. A word about grading One of the key DevOps practices we learn about in this class is the use of automation to increase the speed and repeatability of processes. Automation is utilized during the assignment grading process to review and assess your work. It’s important that you follow the instructions in each assignment and type in required files and resources with the proper names. All names are case sensitive, so a name like "Web1" is not the same as "web1". If you misspell a name, use the wrong case, or put a file in the wrong directory location you will lose points on your assignment. This is the easiest way to lose points, and also the most preventable. You should always double-check your work to make sure it accurately reflects the requirements specified in the assignment. You should always carefully review the content of your files before submitting your assignment. The assignment Let’s get started! Create GitHub repository The first step in the assignment is to setup a Git repository on GitHub. We will use a special solution called GitHub Classroom for this course which automates the process of setting up student assignment repositories. Here are the basic steps: Click on the following link to open Assignment 2 on the GitHub Classroom site: https://classroom.github.com/a/K4zcVmX- (Links to an external site.)Links to an external site. Click on the Accept this assignment button. GitHub Classroom will provide you with a URL (https) to access the assignment repository. Either copy this address to your clipboard or write it down somewhere. You will need to use this address to set up the repository on a Linux server. Example: https://github.com/UST-SEIS665/hw2-seis665-02-spring2019-<your github id>.git At this point your new repository to ready to use. The repository is currently empty. We will put some content in there soon! Launch Linux server The second step in the assignment is to launch a Linux server using AWS EC2. The server should have the following characteristics: Amazon Linux 2 AMI 64-bit (usually the first option listed) Located in a U.S. region (us-east-1) t2.micro instance type All default instance settings (storage, vpm, security group, etc.) I’ve shown you how to launch EC2 instances in class. You can review it on Canvas. Once you launch the new server, it may take a few minutes to provision. Log into server The next step is to log into the Linux server using a terminal program with a secure shell (SSH) support. You can use iTerm2 (Links to an external site.)Links to an external site. on a Mac and GitBash/PuTTY (Links to an external site.)Links to an external site. on a PC. You will need to have the private server key and the public IP address before attempting to log into the server. The server key is basically your password. If you lose it, you will need to terminate the existing instance and launch a new server. I recommend reusing the same key when launching new servers throughout the class. Note, I make this recommendation to make the learning process easier and not because it is a common security practice. I’ve shown you how to use a terminal application to log into the instance using a Windows desktop. Your personal computer or lab computer may be running a different OS version, but the process is still very similar. You can review the videos on the Canvas. Working with Linux If you’ve made it this far, congratulations! You’ve made it over the toughest hurdle. By the end of this course, I promise you will be able to launch and log into servers in your sleep. You should be looking at a login screen that looks something like this: Last login: Mon Mar 21 21:17:54 2016 from 174-20-199-194.mpls.qwest.net __| __|_ ) _| ( / Amazon Linux AMI ___|\___|___| https://aws.amazon.com/amazon-linux-ami/2015.09-release-notes/ 8 package(s) needed for security, out of 17 available Run "sudo yum update" to apply all updates. ec2-user@ip-172-31-15-26 ~]$ Your terminal cursor is sitting at the shell prompt, waiting for you to type in your first command. Remember the shell? It is a really cool program that lets you start other programs and manage services on the Linux system. The rest of this assignment will be spent working with the shell. Note, when you are asked to type in a command in the steps below, don’t type in the dollar-sign ($) character. This is just meant to represent the command prompt. The actual commands are represented by the characters to the right of the command prompt. Let’s start by asking the shell for some help. Type in: $ help The shell provides you with a list of commands you can run along with possible command options. Next, check out one of the pages in the built-in manual: $ man ls A man page will appear with information on how to use the ls command. This command is used to list the contents of file directories. Either space through the contents of the man page or hit q to exit. Most of the core Linux commands have man pages available. But honestly, some of these man pages are a bit hard to understand. Sometimes your best bet is to search on Google if you are trying to figure out how to use a specific command. When you initially log into Linux, the system places you in your home directory. Each user on the system has a separate home directory. Let’s see where your home directory is located: $ pwd The response should be /home/ec2-user. The pwd command is handy to remember if you ever forget what file directory you are currently located in. If you recall from the Linux Hands-on Guide, this directory is also your current working directory. Type in: $ cd / The cd command let’s you change to a new working directory on the server. In this case, we changed to the root (/) directory. This is the parent of all the other directories on the file system. Type in: $ ls The ls command lists the contents of the current directory. As you can see, root directory contains many other directories. You will become familiar with these directories over time. The ls command provides a very basic directory listing. You need to supply the command with some options if you want to see more detailed information. Type in: $ ls -la See how this command provides you with much more detailed information about the files and directories? You can use this detailed listing to see the owner, group, and access control list settings for each file or directory. Do you see any files listed? Remember, the first character in the access control list column denotes whether a listed item is a file or a directory. You probably see a couple files with names like .autofsck. How come you didn’t see this file when you typed in the lscommand without any options? (Try to run this command again to convince yourself.) Files names that start with a period are called hidden files. These files won’t appear on normal directory listings. Type in: $ cd /var Then, type in: $ ls You will see a directory listing for the /var directory. Next, type in: $ ls .. Huh. This directory listing looks the same as the earlier root directory listing. When you use two periods (..) in a directory path that means you are referring to the parent directory of the current directory. Just think of the two dots as meaning the directory above the current directory. Now, type in: $ cd ~ $ pwd Whoa. We’re back at our home directory again. The tilde character (~) is another one of those handy little directory path shortcuts. It always refers to our personal home directory. Keep in mind that since every user has their own home directory, the tilde shortcut will refer to a unique directory for each logged-in user. Most students are used to navigating a file system by clicking a mouse in nested graphical folders. When they start using a command-line to navigate a file system, they sometimes get confused and lose track of their current position in the file system. Remember, you can always use the pwd command to quickly figure out what directory you are currently working in. Let’s make some changes to the file system. We can easily make our own directories on the file system. Type: mkdir test Now type: ls Cool, there’s our new test directory. Let’s pretend we don’t like that directory name and delete it. Type: rmdir test Now it’s gone. How can you be sure? You should know how to check to see if the directory still exists at this point. Go ahead and check. Let’s create another directory. Type in: $ mkdir documents Next, change to the new directory: $ cd documents Did you notice that your command prompt displays the name of the current directory? Something like: [ec2-user@ip-172-31-15-26 documents]$. Pretty handy, huh? Okay, let’s create our first file in the documents directory. This is just an empty file for training purposes. Type in: $ touch paper.txt Check to see that the new file is in the directory. Now, go back to the previous directory. Remember the double dot shortcut? $ cd .. Okay, we don’t like our documents directory any more. Let’s blow it away. Type in: $ rmdir documents Uh oh. The shell didn’t like that command because the directory isn’t empty. Let’s change back into the documents directory. But this time don’t type in the full name of the directory. You can let shell auto-completion do the typing for you. Type in the first couple characters of the directory name and then hit the tab key: $ cd doc<tab> You should use the tab auto-completion feature often. It saves typing and makes working with the Linux file system much much easier. Tab is your friend. Now, remove the file by typing: $ rm paper.txt Did you try to use the tab key instead of typing in the whole file name? Check to make sure the file was deleted from the directory. Next, create a new file: $ touch file1 We like file1 so much that we want to make a backup copy. Type: $ cp file1 file1-backup Check to make sure the new backup copy was created. We don’t really like the name of that new file, so let’s rename it. Type: $ mv file1-backup backup Moving a file to the same directory and giving it a new name is basically the same thing as renaming it. We could have moved it to a different directory if we wanted. Let’s list all of the files in the current directory that start with the letter f: $ ls f* Using wildcard pattern matching in file commands is really useful if you want the command to impact or filter a group of files. Now, go up one directory to the parent directory (remember the double dot shortcut?) We tried to remove the documents directory earlier when it had files in it. Obviously that won’t work again. However, we can use a more powerful command to destroy the directory and vanquish its contents. Behold, the all powerful remove command: $ rm -fr documents Did you remember to use auto-completion when typing in documents? This command and set of options forcibly removes the directory and its contents. It’s a dangerous command wielded by the mightiest Linux wizards. Okay, maybe that’s a bit of an exaggeration. Just be careful with it. Check to make sure the documents directory is gone before proceeding. Let’s continue. Change to the directory /var and make a directory called test. Ugh. Permission denied. We created this darn Linux server and we paid for it. Shouldn’t we be able to do anything we want on it? You logged into the system as a user called ec2-user. While this user can create and manage files in its home directory, it cannot change files all across the system. At least it can’t as a normal user. The ec2-user is a member of the root group, so it can escalate its privileges to super-user status when necessary. Let’s try it: $ sudo mkdir test Check to make sure the directory exists now. Using sudo we can execute commands as a super-user. We can do anything we want now that we know this powerful new command. Go ahead and delete the test directory. Did you remember to use sudo before the rmdir command? Check to make sure the directory is gone. You might be asking yourself the question: why can we list the contents of the /var directory but not make changes? That’s because all users have read access to the /var directory and the ls command is a read function. Only the root users or those acting as a super-user can write changes to the directory. Let’s go back to our home directory: $ cd ~ Editing text files is a really common task on Linux systems because many of the application configuration files are text files. We can create a text file by using a text editor. Type in: $ nano myfile.conf The shell starts up the nano text editor and places your terminal cursor in the editing screen. Nano is a simple text-based word processor. Type in a few lines of text. When you’re done writing your novel, hit ctrl-x and answer y to the prompt to save your work. Finally, hit enter to save the text to the filename you specified. Check to see that your file was saved in the directory. You can take a look at the contents of your file by typing: $ cat myfile.conf The cat command displays your text file content on the terminal screen. This command works fine for displaying small text files. But if your file is hundreds of lines long, the content will scroll down your terminal screen so fast that you won’t be able to easily read it. There’s a better way to view larger text files. Type in: $ less myfile.conf The less command will page the display of a text file, allowing you to page through the contents of the file using the space bar. Your text file is probably too short to see the paging in action though. Hit q to quit out of the less text viewer. Hit the up-arrow key on your keyboard a few times until the commmand nano myfile.conf appears next to your command prompt. Cool, huh? The up-arrow key allows you to replay a previously run command. Linux maintains a list of all the commands you have run since you logged into the server. This is called the command history. It’s a really useful feature if you have to re-run a complex command again. Now, hit ctrl-c. This cancels whatever command is displayed on the command line. Type in the following command to create a couple empty files in the directory: $ touch file1 file2 file3 Confirm that the files were created. Some commands, like touch. allow you to specify multiple files as arguments. You will find that Linux commands have all kinds of ways to make tasks more efficient like this. Throughout this assignment, we have been running commands and viewing results on the terminal screen. The screen is the standard place for commands to output results. It’s known as the standard out (stdout). However, it’s really useful to output results to the file system sometimes. Type in: $ ls > listing.txt Take a look at the directory listing now. You just created a new file. View the contents of the listing.txt file. What do you see? Instead of sending the output from the ls command to the screen we sent it to a text file. Let’s try another one. Type: $ cat myfile.conf > listing.txt Take a look at the contents of the listing.txt file again. It looks like your myfile.conf file now. It’s like you made a copy of it. But what happened to the previous content in the listing.txt file? When you redirect the output of a command using the right angle-bracket character (>), the output overwrites the existing file. Type this command in: $ cat myfile.conf >> listing.txt Now look at the contents of the listing.txt file. You should see your original content displayed twice. When you use two angle-bracket characters in the commmand the output appends (or adds to) the file instead of overwriting it. We redirected the output from a command to a text file. It’s also possible to redirect the input to a command. Typically we use a keyboard to provide input, but sometimes it makes more sense to input a file to a command. For example, how many words are in your new listing.txt file? Let’s find out. Type in: $ wc -w < listing.txt Did you get a number? This command inputs the listing.txt file into a word count program called wc. Type in the command: $ ls /usr/bin The terminal screen probably scrolled quickly as filenames flashed by. The /usr/bin directory holds quite a few files. It would be nice if we could page through the contents of this directory. Well, we can. We can use a special shell feature called pipes. In previous steps, we redirected I/O using the file system. Pipes allow us to redirect I/O between programs. We can redirect the output from one program into another. Type in: $ ls /usr/bin | less Now the directory listing is paged. Hit the spacebar to page through the listing. The pipe, represented by a vertical bar character (|), takes the output from the ls command and redirects it to the less command where the resulting output is paged. Pipes are super powerful and used all the time by savvy Linux operators. Hit the q key to quit the paginated directory listing command. Working with shell scripts Now things are going to get interesting. We’ve been manually typing in commands throughout this exercise. If we were running a set of repetitive tasks, we would want to automate the process as much as possible. The shell makes it really easy to automate tasks using shell scripts. The shell provides many of the same features as a basic procedural programming language. Let’s write some code. Type in this command: $ j=123 $ echo $j We just created a variable named j referencing the string 123. The echo command printed out the value of the variable. We had to use a dollar sign ($) when referencing the variable in another command. Next, type in: $ j=1+1 $ echo $j Is that what you expected? The shell just interprets the variable value as a string. It’s not going to do any sort of computation. Typing in shell script commands on the command line is sort of pointless. We want to be able to create scripts that we can run over-and-over. Let’s create our first shell script. Use the nano editor to create a file named myscript. When the file is open in the editor, type in the following lines of code: #!/bin/bash echo Hello $1 Now quit the editor and save your file. We can run our script by typing: $ ./myscript World Er, what happened? Permission denied. Didn’t we create this file? Why can’t we run it? We can’t run the script file because we haven’t set the execute permission on the file. Type in: $ chmod u+x myscript This modifies the file access control list to allow the owner of the file to execute it. Let’s try to run the command again. Hit the up-arrow key a couple times until the ./myscript World command is displayed and hit enter. Hooray! Our first shell script. It’s probably a bit underwhelming. No problem, we’ll make it a little more complex. The script took a single argument called World. Any arguments provided to a shell script are represented as consecutively numbered variables inside the script ($1, $2, etc). Pretty simple. You might be wondering why we had to type the ./ characters before the name of our script file. Try to type in the command without them: $ myscript World Command not found. That seems a little weird. Aren’t we currently in the directory where the shell script is located? Well, that’s just not how the shell works. When you enter a command into the shell, it looks for the command in a predefined set of directories on the server called your PATH. Since your script file isn’t in your special path, the shell reports it as not found. By typing in the ./ characters before the command name you are basically forcing the shell to look for your script in the current directory instead of the default path. Create another file called cleanup using nano. In the file editor window type: #!/bin/bash # My cleanup script mkdir archive mv file* archive Exit the editor window and save the file. Change the permissions on the script file so that you can execute it. Now run the command: $ ./cleanup Take a look at the file directory listing. Notice the archive directory? List the contents of that directory. The script automatically created a new directory and moved three files into it. Anything you can do manually at a command prompt can be automated using a shell script. Let’s create one more shell script. Use nano to create a script called namelist. Here is the content of the script: #!/bin/bash # for-loop test script names='Jason John Jane' for i in $names do echo Hello $i done Change the permissions on the script file so that you can execute it. Run the command: $ ./namelist The script will loop through a set of names stored in a variable displaying each one. Scripts support several programming constructs like for-loops, do-while loops, and if-then-else. These building blocks allow you to create fairly complex scripts for automating tasks. Installing packages and services We’re nearing the end of this assignment. But before we finish, let’s install some new software packages on our server. The first thing we should do is make sure all the current packages installed on our Linux server are up-to-date. Type in: $ sudo yum update -y This is one of those really powerful commands that requires sudo access. The system will review the currently installed packages and go out to the Internet and download appropriate updates. Next, let’s install an Apache web server on our system. Type in: $ sudo yum install httpd -y Bam! You probably never knew that installing a web server was so easy. We’re not going to actually use the web server in this exercise, but we will in future assignments. We installed the web server, but is it actually running? Let’s check. Type in: $ sudo service httpd status Nope. Let’s start it. Type: $ sudo service httpd start We can use the service command to control the services running on the system. Let’s setup the service so that it automatically starts when the system boots up. Type in: $ sudo chkconfig httpd on Cool. We installed the Apache web server on our system, but what other programs are currently running? We can use the pscommand to find out. Type in: $ ps -ax Lots of processes are running on our system. We can even look at the overall performance of our system using the topcommand. Let’s try that now. Type in: $ top The display might seem a little overwhelming at first. You should see lots of performance information displayed including the cpu usage, free memory, and a list of running tasks. We’re almost across the finish line. Let’s make sure all of our valuable work is stored in a git repository. First, we need to install git. Type in the command: $ sudo yum install git -y Check your work It’s very important to check your work before submitting it for grading. A misspelled, misplaced or missing file will cost you points. This may seem harsh, but the reality is that these sorts of mistakes have consequences in the real world. For example, a server instance could fail to launch properly and impact customers because a single required file is missing. Here is what the contents of your git repository should look like before final submission: ┣archive ┃ ┣ file1 ┃ ┣ file2 ┃ ┗ file3 ┣ namelist ┗ myfile.conf Saving our work in the git repository Next, make sure you are still in your home directory (/home/ec2-user). We will install the git repository you created at the beginning of this exercise. You will need to modify this command by typing in the GitHub repository URL you copied earlier. $ git clone <your GitHub URL here>.git Example: git clone https://github.com/UST-SEIS665/hw2-seis665-02-spring2019-<your github id>.git The git application will ask you for your GitHub username and password. Note, if you have multi-factor authentication enabled on your GitHub account you will need to provide a personal token instead of your password. Git will clone (copy) the repository from GitHub to your Linux server. Since the repository is empty the clone happens almost instantly. Check to make sure that a sub-directory called "hw2-seis665-02-spring2019-<username>" exists in the current directory (where <username> is your GitHub account name). Git automatically created this directory as part of the cloning process. Change to the hw2-seis665-02-spring2019-<username> directory and type: $ ls -la Notice the .git hidden directory? This is where git actually stores all of the file changes in your repository. Nothing is actually in your repository yet. Change back to the parent directory (cd ..). Next, let’s move some of our files into the repository. Type: $ mv archive hw2-seis665-02-spring2019-<username> $ mv namelist hw2-seis665-02-spring2019-<username> $ mv myfile.conf hw2-seis665-02-spring2019-<username> Hopefully, you remembered to use the auto-complete function to reduce some of that typing. Change to the hw2-seis665-02-spring2019-<username> directory and list the directory contents. Your files are in the working directory, but are not actually stored in the repository because they haven’t been committed yet. Type in: $ git status You should see a list of untracked files. Let’s tell git that we want these files tracked. Type in: $ git add * Now type in the git status command again. Notice how all the files are now being tracked and are ready to be committed. These files are in the git staging area. We’ll commit them to the repository next. Type: $ git commit -m 'assignment 2 files' Next, take a look at the commit log. Type: $ git log You should see your commit listed along with an assigned hash (long string of random-looking characters). Finally, let’s save the repository to our GitHub account. Type in: $ git push origin master The git client will ask you for your GitHub username and password before pushing the repository. Go back to the GitHub.com website and login if you have been logged out. Click on the repository link for the assignment. Do you see your files listed there? Congratulations, you completed the exercise! Terminate server The last step is to terminate your Linux instance. AWS will bill you for every hour the instance is running. The cost is nominal, but there’s no need to rack up unnecessary charges. Here are the steps to terminate your instance: Log into your AWS account and click on the EC2 dashboard. Click the Instances menu item. Select your server in the instances table. Click on the Actions drop down menu above the instances table. Select the Instance State menu option Click on the Terminate action. Your Linux instance will shutdown and disappear in a few minutes. The EC2 dashboard will continue to display the instance on your instance listing for another day or so. However, the state of the instance will be terminated. Submitting your assignment — IMPORTANT! If you haven’t already, please e-mail me your GitHub username in order to receive credit for this assignment. There is no need to email me to tell me that you have committed your work to GitHub or to ask me if your GitHub submission worked. If you can see your work in your GitHub repository, I can see your work.

It entails an initial free membership registration and thereafter funding of a personal wallet with the platform’s native utility asset – the payME Pay Token (payME) Contestants automatically qualify to either make use of the premium entry to the quiz contest or use the payment option. Any of the quiz contests is a set of Ten (10) objective intra-changeable questions. Contestants are expected to provide correct answers to the questions within the swiftest timeframe. Each contestant’s result is displayed after the last question is answered on the contestants’ quiz page and thereafter, updated on the general result page. Weekly participation is limitless for contestants entering as regular quizzers but limited to 10 entries for the premium contestants. Only the best result amongst a Quizzer’s several attempts is registered for the contestant despite when it’s played each week. The first ranked 5% of the weekly contestants based on the most correct answers provided within the swiftest timeframe wins. The Playing Schedule Contests start every Monday at 12 am and end Saturday at 11.59 pm. From 12 am to 11.59 pm every Sunday, results are automatically displayed on the Result Page. The Web Portal Interface and Functions The web/mobile app has interactive interfaces and modules that help Quizzers easily glide through their activities. Some of these modules are described below: a. Wallet: A participant is expected to link his personal blockchain wallet after registration and fund it to enable him gain access to games. Only a decentralized crypto wallet is accepted. b. Quiz: This is 10 revolving questions, each having 4 objectives with 1 possible answer. When entering as a regular quizzer, once the play (ACE or COS) quiz button is clicked, $0.50 worth of payME Token will be debited from the quizzer’s wallet and credited to the platform’s wallet. Next, intra-changeable questions from the Question Bank will be appearing in non sequence routine. Quizzers are expected to provide the correct answers to each of the 10 questions as fast as they could and within 18 seconds. Immediately, after answering the 10th question, the quizzer’s result will display automatically on both the quizzing page and the general result dashboard. c. Tutorial Quiz: As the name implies, this is a free gaming zone created to enable holders of payMe token who may not want to engage in the contest, but want to improve their intellect through quizzing on the platform. However, the user must have payMe token worth $50 USD in his/her personal connected wallet to gain free access at anytime. d. Result Dashboard: this is a general result center for all Contestants. It updates automatically after each game is played during the play period, and according to the most correct answers within the swiftest time frame. That means that if a million quizzers scored 100/100, the system will display their result according to the fastest to answer the entire question using nanoseconds (an SI unit of time equal to one billionth of a second) in computing. So, be rest assured that it is impractical and impossible for 2 Quizzers to tally in the result. This makes payMe unique in the way winners are determined – fastest finger first! Updating of the dashboard however is programmed to freeze once it is 12 am every Sunday to determine the winners by publishing the result of the past week until 12 am on Monday when it continues its routine update.

While the remaining 80% of the Winners earn 60% of the revenue share on an equal distribution rate. Practically, whatever revenue is generated weekly, 50% is automatically remitted to the incentivizing pool wallet and from there, the topmost 5% of the total participants are rewarded in the following ratio: 40% is equally shared to the topmost 20% while 60% is equally shared to the rest 80% of the winners. Winners claim button would automatically turn green by 12am every Sunday and they can claim their prizes themselves from their dashboard. Every Year, each of the 10 most intelligent Quizzers, drawn from the 52 weeks’ cumulative results of all participants in the ACE Quiz contests are rewarded with a Scholarship Award worth $1000 USDT in payME Token. Criteria is participating in every week of play. Cost of Play Cost of Game $0.50 worth of payME Token per game entry or with a single weekly subscription with payMe token worth $5. NB: The rewards are available for each quizzer's claim from Sunday at 12 am (according to the Nigerian calendar and time).

A backdoor is a tool used to gain remote access to a machine. Typically, backdoor utilities such as NetCat have 2 main functions: to pipe remote input into cmd or bash and output the response. This is useful, but it is also limited. BetterBackdoor overcomes these limitations by including the ability to inject keystrokes, get screenshots, transfer files, and many other tasks. Features BetterBackdoor can create and control a backdoor. This created backdoor can: Run Command Prompt commands Run PowerShell scripts Run DuckyScripts to inject keystrokes Exfiltrate files based on extension Exfiltrate Microsoft Edge and WiFi passwords Send and receive files to and from victim's computer Start a KeyLogger Get a screenshot of victim's computer Get text copied to victim's clipboard Get contents from a victim's file (cat) This backdoor uses a client and server socket connection to communicate. The attacker starts a server and the victim connects to this server as a client. Once a connection is established, commands can be sent to the client in order to control the backdoor. To create the backdoor, BetterBackdoor: Creates 'run.jar', the backdoor jar file, and copied it to directory 'backdoor'. Appends a text file containing the server's IPv4 address to 'run.jar'. If desired, copies a Java Runtime Environment to 'backdoor' and creates batch file 'run.bat' for running the backdoor in the packaged Java Runtime Environment. To start the backdoor on a victim PC, transfer all files from the directory 'backdoor' onto a victim PC. If a JRE is packaged with the backdoor, execute run.bat, otherwise execute run.jar. This will start the backdoor on the victim's PC. Once running, to control the backdoor you must return to BetterBackdoor and run option 1 at start while connected to the same WiFi network as the victim's computer.

早期的计算机使用7位的ASCII编码，为了处理汉字，程序员设计了用于简体中文的GB2312和用于繁体中文的big5。 GB2312(1980年)一共收录了7445个字符，包括6763个汉字和682个其它符号。汉字区的内码范围高字节从B0-F7，低字节从A1-FE，占用的码位是72*94=6768。其中有5个空位是D7FA-D7FE。 GB2312支持的汉字太少。1995年的汉字扩展规范GBK1.0收录了21886个符号，它分为汉字区和图形符号区。汉字区包括21003个字符。2000年的GB18030是取代GBK1.0的正式国家标准。该标准收录了27484个汉字，同时还收录了藏文、蒙文、维吾尔文等主要的少数民族文字。现在的PC平台必须支持GB18030，对嵌入式产品暂不作要求。所以手机、MP3一般只支持GB2312。 从ASCII、GB2312、GBK到GB18030，这些编码方法是向下兼容的，即同一个字符在这些方案中总是有相同的编码，后面的标准支持更多的字符。在这些编码中，英文和中文可以统一地处理。区分中文编码的方法是高字节的最高位不为0。按照程序员的称呼，GB2312、GBK到GB18030都属于双字节字符集 (DBCS)。 有的中文Windows的缺省内码还是GBK，可以通过GB18030升级包升级到GB18030。不过GB18030相对GBK增加的字符，普通人是很难用到的，通常我们还是用GBK指代中文Windows内码。 这里还有一些细节： GB2312的原文还是区位码，从区位码到内码，需要在高字节和低字节上分别加上A0。 在DBCS中，GB内码的存储格式始终是big endian，即高位在前。 GB2312的两个字节的最高位都是1。但符合这个条件的码位128*128=16384个。所以GBK和GB18030的低字节最高位都可能不是1。不过这不影响DBCS字符流的解析：在读取DBCS字符流时，只要遇到高位为1的字节，就可以将下两个字节作为一个双字节编码，而不用管低字节的高位是什么。 前面提到从ASCII、GB2312、GBK到GB18030的编码方法是向下兼容的。而Unicode只与ASCII兼容（更准确地说，是与ISO-8859-1兼容），与GB码不兼容。例如“汉”字的Unicode编码是6C49，而GB码是BABA。 Unicode也是一种字符编码方法，不过它是由国际组织设计，可以容纳全世界所有语言文字的编码方案。Unicode的学名是"Universal Multiple-Octet Coded Character Set"，简称为UCS。UCS可以看作是"Unicode Character Set"的缩写。 根据维基百科全书(http://zh.wikipedia.org/wiki/)的记载：历史上存在两个试图独立设计Unicode的组织，即国际标准化组织（ISO）和一个软件制造商的协会（unicode.org）。ISO开发了ISO 10646项目，Unicode协会开发了Unicode项目。 在1991年前后，双方都认识到世界不需要两个不兼容的字符集。于是它们开始合并双方的工作成果，并为创立一个单一编码表而协同工作。从Unicode2.0开始，Unicode项目采用了与ISO 10646-1相同的字库和字码。 目前两个项目仍都存在，并独立地公布各自的标准。Unicode协会现在的最新版本是2005年的Unicode 4.1.0。ISO的最新标准是10646-3:2003。 UCS规定了怎么用多个字节表示各种文字。怎样传输这些编码，是由UTF(UCS Transformation Format)规范规定的，常见的UTF规范包括UTF-8、UTF-7、UTF-16。 IETF的RFC2781和RFC3629以RFC的一贯风格，清晰、明快又不失严谨地描述了UTF-16和UTF-8的编码方法。我总是记不得IETF是Internet Engineering Task Force的缩写。但IETF负责维护的RFC是Internet上一切规范的基础。 3、UCS-2、UCS-4、BMP UCS有两种格式：UCS-2和UCS-4。顾名思义，UCS-2就是用两个字节编码，UCS-4就是用4个字节（实际上只用了31位，最高位必须为0）编码。下面让我们做一些简单的数学游戏： UCS-2有2^16=65536个码位，UCS-4有2^31=2147483648个码位。 UCS-4根据最高位为0的最高字节分成2^7=128个group。每个group再根据次高字节分为256个plane。每个plane根据第3个字节分为256行 (rows)，每行包含256个cells。当然同一行的cells只是最后一个字节不同，其余都相同。 group 0的plane 0被称作Basic Multilingual Plane, 即BMP。或者说UCS-4中，高两个字节为0的码位被称作BMP。 将UCS-4的BMP去掉前面的两个零字节就得到了UCS-2。在UCS-2的两个字节前加上两个零字节，就得到了UCS-4的BMP。而目前的UCS-4规范中还没有任何字符被分配在BMP之外。 4、UTF编码 UTF-8就是以8位为单元对UCS进行编码。从UCS-2到UTF-8的编码方式如下： UCS-2编码(16进制) UTF-8 字节流(二进制) 0000 - 007F 0xxxxxxx 0080 - 07FF 110xxxxx 10xxxxxx 0800 - FFFF 1110xxxx 10xxxxxx 10xxxxxx 例如“汉”字的Unicode编码是6C49。6C49在0800-FFFF之间，所以肯定要用3字节模板了：1110xxxx 10xxxxxx 10xxxxxx。将6C49写成二进制是：0110 110001 001001， 用这个比特流依次代替模板中的x，得到：11100110 10110001 10001001，即E6 B1 89。 读者可以用记事本测试一下我们的编码是否正确。 UTF-16以16位为单元对UCS进行编码。对于小于0x10000的UCS码，UTF-16编码就等于UCS码对应的16位无符号整数。对于不小于0x10000的UCS码，定义了一个算法。不过由于实际使用的UCS2，或者UCS4的BMP必然小于0x10000，所以就目前而言，可以认为UTF-16和UCS-2基本相同。但UCS-2只是一个编码方案，UTF-16却要用于实际的传输，所以就不得不考虑字节序的问题。 5、UTF的字节序和BOM UTF-8以字节为编码单元，没有字节序的问题。UTF-16以两个字节为编码单元，在解释一个UTF-16文本前，首先要弄清楚每个编码单元的字节序。例如收到一个“奎”的Unicode编码是594E，“乙”的Unicode编码是4E59。如果我们收到UTF-16字节流“594E”，那么这是“奎”还是“乙”？ Unicode规范中推荐的标记字节顺序的方法是BOM。BOM不是“Bill Of Material”的BOM表，而是Byte Order Mark。BOM是一个有点小聪明的想法： 在UCS编码中有一个叫做"ZERO WIDTH NO-BREAK SPACE"的字符，它的编码是FEFF。而FFFE在UCS中是不存在的字符，所以不应该出现在实际传输中。UCS规范建议我们在传输字节流前，先传输字符"ZERO WIDTH NO-BREAK SPACE"。 这样如果接收者收到FEFF，就表明这个字节流是Big-Endian的；如果收到FFFE，就表明这个字节流是Little-Endian的。因此字符"ZERO WIDTH NO-BREAK SPACE"又被称作BOM。 UTF-8不需要BOM来表明字节顺序，但可以用BOM来表明编码方式。字符"ZERO WIDTH NO-BREAK SPACE"的UTF-8编码是EF BB BF（读者可以用我们前面介绍的编码方法验证一下）。所以如果接收者收到以EF BB BF开头的字节流，就知道这是UTF-8编码了。 Windows就是使用BOM来标记文本文件的编码方式的。 6、进一步的参考资料 本文主要参考的资料是 "Short overview of ISO-IEC 10646 and Unicode" (http://www.nada.kth.se/i18n/ucs/unicode-iso10646-oview.html)。 我还找了两篇看上去不错的资料，不过因为我开始的疑问都找到了答案，所以就没有看： "Understanding Unicode A general introduction to the Unicode Standard" (http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&item_id=IWS-Chapter04a) "Character set encoding basics Understanding character set encodings and legacy encodings" (http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&item_id=IWS-Chapter03) 我写过UTF-8、UCS-2、GBK相互转换的软件包，包括使用Windows API和不使用Windows API的版本。以后有时间的话，我会整理一下放到我的个人主页上(http://fmddlmyy.home4u.china.com/)。 Unicode,GBK,GB2312,UTF-8概念基础 本部分采用重用，转载一篇文章来完成这部分的目标。 来源：holen'blog 对字符编码与Unicode,ISO 10646,UCS,UTF8,UTF16,GBK,GB2312的理解 地址：http://blog.donews.com/holen/archive/2004/11/30/188182.aspx Unicode: unicode.org制定的编码机制, 要将全世界常用文字都函括进去. 在1.0中是16位编码, 由U+0000到U+FFFF. 每个2byte码对应一个字符; 在2.0开始抛弃了16位限制, 原来的16位作为基本位平面, 另外增加了16个位平面, 相当于20位编码, 编码范围0到0x10FFFF. 各个编码集的区别和适用范围 目前计算机中用得最广泛的字符集及其编码，是由美国国家标准局(ANSI)制定的ASCII码（American Standard Code for Information Interchange，美国标准信息交换码），它已被国际标准化组织（ISO）定为国际标准，称为ISO 646标准。适用于所有拉丁文字字母，ASCII码有7位码和8位码两种形式。 我们知道，在计算机内部，所有的信息最终都表示为一个二进制的字符串。每一个二进制位（bit）有0和1两种状态，因此八个二进制位就可以组合出256种状态，这被称为一个字节（byte）。也就是说，一个字节一共可以用来表示256种不同的状态，每一个状态对应一个符号，就是256个符号，从0000000到11111111。 英语用128个符号编码就够了，但是用来表示其他语言，128个符号是不够的。比如，在法语中，字母上方有注音符号，它就无法用ASCII码表示。于是，一些欧洲国家就决定，利用字节中闲置的最高位编入新的符号。比如，法语中的é的编码为130（二进制10000010）。这样一来，这些欧洲国家使用的编码体系，可以表示最多256个符号。 但是，这里又出现了新的问题。不同的国家有不同的字母，因此，哪怕它们都使用256个符号的编码方式，代表的字母却不一样。比如，130在法语编码中代表了é，在希伯来语编码中却代表了字母Gimel (ג)，在俄语编码中又会代表另一个符号。但是不管怎样，所有这些编码方式中，0—127表示的符号是一样的，不一样的只是128—255的这一段,所以出现后面的统一编码方式。 注:若想得到更详细的参见http://ascii.911cha.com/ 2、各地的方言 在中国，大陆最常用的就是GBK18030编码，除此之外还有GBK，GB2312，这几个编码的关系是这样的。 字符必须编码后才能被计算机处理。计算机使用的缺省编码方式就是计算机的内码。早期的计算机使用7位的ASCII编码，但为了处理汉字，又设计出用于简体中文的GB2312和用于繁体中文的big5。 GB2312(1980年)一共收录了7445个字符，包括6763个汉字和682个其它符号。汉字区的内码范围高字节从B0-F7，低字节从A1-FE，占用的码位是72*94=6768。其中有5个空位是D7FA-D7FE。 GB2312支持的汉字太少。1995年的汉字扩展规范GBK1.0收录了21886个符号，它分为汉字区和图形符号区。汉字区包括21003个字符。 从ASCII、GB2312到GBK，这些编码方法是向下兼容的，即同一个字符在这些方案中总是有相同的编码，后面的标准支持更多的字符。在这些编码中，英文和中文可以统一地处理。区分中文编码的方法是高字节的最高位不为0。按照程序员的称呼，GB2312、GBK都属于双字节字符集 (DBCS)。 2000年的GB18030是取代GBK1.0的正式国家标准。该标准收录了27484个汉字，同时还收录了藏文、蒙文、维吾尔文等主要的少数民族文字。从汉字字汇上说，GB18030在GB13000.1的20902个汉字的基础上增加了CJK扩展A的6582个汉字（Unicode码0x3400-0x4db5），一共收录了27484个汉字。 CJK就是中日韩的意思。Unicode为了节省码位，将中日韩三国语言中的文字统一编码。GB13000.1就是ISO/IEC 10646-1的中文版，相当于Unicode 1.1。 GB18030的编码采用单字节、双字节和4字节方案。其中单字节、双字节和GBK是完全兼容的。4字节编码的码位就是收录了CJK扩展A的6582个汉字。例如：UCS的0x3400在GB18030中的编码应该是8139EF30，UCS的0x3401在GB18030中的编码应该是8139EF31。 微软提供了GB18030的升级包，但这个升级包只是提供了一套支持CJK扩展A的6582个汉字的新字体：新宋体-18030，并不改变内码。Windows 的内码仍然是GBK。 也就是说Big5支持繁体中文，GB2312支持简体中文，Big5,GB2312是GBK的子集，GBK是GB18030的子集 日本：SJIS编码 注: 汉字编码简明对照表http://www.knowsky.com/resource/gb2312tbm.htm 3、GB2312 GB2312标准共收录6763个汉字，其中一级汉字3755个，二级汉字3008个；同时，GB2312收录了包括拉丁字母、希腊字母、日文平假名及片假名字母、俄罗斯语西里尔字母在内的682个全形字符。 GB2312的出现，基本满足了汉字的计算机处理需要，它所收录的汉字已经覆盖99.75%的使用频率。GB2312中对所收汉字进行了“分区”处理，每区含有94个汉字/符号。这种表示方式也称为区位码。 01-09区为特殊符号。 16-55区为一级汉字，按拼音排序。 56-87区为二级汉字，按部首/笔画排序。 10-15区及88-94区则未有编码。 举例来说，“啊”字是GB2312之中的第一个汉字，它的区位码就是1601。字节结构在使用GB2312的程序中，通常采用EUC储存方法，以便兼容于ASCII。每个汉字及符号以两个字节来表示。第一个字节称为“高位字节”，第二个字节称为“低位字节”。 “高位字节”使用了0xA1-0xF7(把01-87区的区号加上0xA0)，“低位字节”使用了0xA1-0xFE(把01-94加上0xA0)。例如“啊”字在大多数程序中，会以0xB0A1储存。（与区位码对比：0xB0=0xA0+16,0xA1=0xA0+1）。 所以GB2312编码中汉字区码的十进制是从176到247，位码是从161到255.之所以存储了6763小于82*94=6768，是因为在区码为215，位码为250-254之间共五个编码没有汉字编码，所以6768-5=6763个。 4、Unicode 如果把各种文字编码形容为各地的方言，那么Unicode就是世界各国合作开发的一种语言。 在这种语言环境下，不会再有语言的编码冲突，在同屏下，可以显示任何语言的内容，这就是Unicode的最大好处。 那么Unicode是如何编码的呢？其实非常简单。 就是将世界上所有的文字用２个字节统一进行编码。可能你会问，２个字节最多能够表示65536个编码，够用吗？ Unicode的学名是"Universal Multiple-Octet Coded Character Set"，简称为UCS。现在用的是UCS-2，即２个字节编码. 以现在的发展肯定是不够用得,如《康熙字典》收录了四万七千零三十五字，《汉语大字典》收录了五万六千多个。到目前为止，国际标准组织（ISO）制定国际标准时，共收集到汉字七万多字,所以出现UCS-4, 即4个字节编码，由原先的65536个编码扩展至将近100万编码。 注: 中日韩汉字Unicode编码表:http://www.chi2ko.com/tool/CJK.htm 查询需要Unicode编码的字符: http://www.unicode.org/charts/unihan.html http://www.nengcha.com/code/unicode/ 5、Unicode Big Endian和Little Endian 上面提到了一个字符可能占用多个字节，那么这多个字节在计算机中如何存储呢？比如字符0xabcd，它的存储格式到底是 AB CD，还是 CD AB 呢？ 实际上两者都有可能，并分别有不同的名字。如果存储为 AB CD，则称为Big Endian；如果存储为 CD AB，则称为Little Endian。 具体来说，以下这种存储格式为Big Endian，因为值(0xabcd)的高位(0xab)存储在前面： 地址 值 0x00000000 AB 0x00000001 CD 相反，以下这种存储格式为Little Endian： 地址 值 0x00000000 CD 0x00000001 AB 6、兼容codepage 那么既然统一了编码，如何兼容原先各国的文字编码呢？这个时候就需要codepage了。 什么是codepage？codepage就是各国的文字编码和Unicode之间的映射表。比如简体中文和Unicode的映射表就是CP936，点这里查看官方的映射表。 以下是几个常用的codepage，相应的修改上面的地址的数字即可。 codepage=936 简体中文GBK codepage=950 繁体中文BIG5 codepage=437 美国/加拿大英语 codepage=932 日文 codepage=949 韩文 codepage=866 俄文 codepage=65001 unicode UFT-8 从936中随意取一行，例如：0x9993 0x6ABD #CJK UNIFIED IDEOGRAPH.前面的编码是GBK的编码，后面的是Unicode。通过查这张表，就能简单的实现GBK和Unicode之间的转换 7、UTF-8 现在明白了Unicode，那么UTF-8又是什么呢？又为什么会出现UTF-8呢？ Unicode的最初目标，是用1个16位的编码来为超过65000字符提供映射。但这还不够，它不能覆盖全部历史上的文字，也不能解决传输的问题，尤其在那些基于网络的应用中。 因此，Unicode用一些基本的保留字符制定了三套编码方式。它们分别是UTF-8,UTF-16和UTF-32。正如名字所示，在UTF－8中，字符是以8位序列来编码的，用一个或几个字节来表示一个字符。这种方式的最大好处，是UTF－8保留了ASCII字符的编码做为它的一部分，例如，在UTF－8和ASCII中，“A”的编码都是0x41. 例:11100100 10111101 10100000à0xE4BDA0 “你”字的UTF-8编码 01001111 01100000 à0x4F60 “你”的Unicode编码 按照UTF-8的编码规则，11100100 10111101 10100000分解如下：xxxx0100 xx111101 xx100000,把除了x之外的数字拼接在一起，01001111 01100000就变成“你”的Unicode编码了.注意UTF-8的最前面３个1，表示整个UTF-8串是由３个字节构成的经过UTF-8编码之后，再也不会出现敏感字符了，因为最高位始终为1。 Unicode和UTF-8之间的转换关系表: 0000 0000-0000 007F | 0xxxxxxx 0000 0000-0080 07FF | 110xxxxx 10xxxxxx 0000 0800-0000 FFFF | 1110xxxx 10xxxxxx 10xxxxxx 0001 0000-0010 FFFF | 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx Unicode编码转换到UTF-8,简单的把Unicode字节流套到x中就变成UTF-8了。

Validation in the PC world alludes to the demonstration of affirming the credibility of the client's computerized personality guarantee. Right now, mainstream confirmation components are for the most part based the accompanying variables: something that the client has (an item), knows (a mystery), or extraordinarily speaks to him (biometric identifiers). In the easiest structure, a framework that requires verification challenges the client for a mystery, commonly a couple of username and secret word. The section of the right pair awards access on the framework's administrations or assets. Shockingly, this methodology is defenseless to a few weaknesses and disadvantages. These deficiencies range from client chose frail or effectively guessable passwords to more modern dangers, for example, malware and console sniffers(keyloggers) etc. To minimize the vulnerabilities, we use a system of random OTP send to registered email id of the user at the time of login so as to prevent the hacker from gaining access to the resources even when he has the password and OTP generated is always unique so unless the hacker has access to emails of the user the system is secure. We have minimized the use of session variable and cookies in the proposed system sensitive data is only stored in database that too using AES encryption. This property alone delivers assaults including word reference assaults and console sniffers computationally hard expanding our capacity to safeguard against brute force attacks. Although biometric authentication systems are considered to be more secure, but in web applications it is not feasible to implement such resource intensive authentication mechanisms thus multifactor authentication using is the balance between secure and user-friendly systems. Multifaceted verification is typically cultivated by joining the customary content-based confirmation with another factor. These elements can incorporate keen cards, USB tokens, handheld gadgets, or one-time secret phrase tokens. Having at least two variables fortifies the resources. The point of the proposed framework is to furnish the client with the safer verification. In this task, the proposed framework is a Multi-factor Authentication System for giving greater security to profoundly classified information. Our methodology conquers the restrictions of the conventional password frameworks.
