BASIC 7

  • cal command is the key
  • After a lot of searches, I found this https://www.linuxquestions.org/questions/general-10/unix-cal-command-in-an-odd-situation-370968/
  • The website has set up a script that returns the output from the UNIX cal command. So in the input box, I could type ‘2005’ and hit enter, and it would run the cal command and that year, then return the output on the webpage to view that calendar
  • There is a file (which I don't know the name of) in that dir where the cal command is executed, what would be a possible way to enter something in that text box to find out what the name of it is?
  • Just “ ls ” or “ls -la ” wouldn't work
  • [ cal 2001, cal -y, cal -j ] : this is what happens when we type a year or a flag like “-y” (cal) so type:

2022; ls

  • and it worked
  • Completed

Bug Boundy Methodology, Tools & Resources

Start by defining a clear objective, such as exploiting a remote code execution (RCE) vulnerability or bypassing authentication on your target. Then, consider how you can achieve this goal using various attack vectors like XSS, SSRF, or others - these are simply tools to help you reach your objective. Use the target as how a normal user would, while browsing keep these questions in mind: 1)How does the app pass data? 2)How/where does the app talk about users? 3)Does the app have multi-tenancy or user levels? 4)Does the app have a unique threat model? 5)Has there been past security research & vulnerabilities? 6)How does the app handle XSS, CSRF, and code injection?

Install & set up mitmweb or mitmproxy in Linux

Step 1: Go to the mitmproxy page and download the binaries. Step 2: Install the downloaded tar file with the command " tar -xzf <filename>.tar.gz " Step 3: In the FoxyProxy add the proxy 127.0.0.1:8080  and turn it on.

Making CHIP-8 emulator in C

  Chip8 doc link | Components | Opcode Table GitHub - AdithyakrishnaV/Chip8_Emulator--Interpreter Contribute to AdithyakrishnaV/Chip8_Emulator--Interpreter development by creating an account on GitHub. github.com CHIP-8 programs are binary files, and your emulator must read them and operate on the bytes. You will also need a way to draw graphics to the screen and read keypresses. Many graphical libraries can do this for you or use something like SDL directly. CHIP-8 components Display 64 pixels wide and 32 pixels tall. Each pixel is a boolean value, or a bit; can be on or off (“off” pixel was just black, and “on” was white). We’ll use SDL for rendering: SDL initialization Not initialize:- returns -1  Error message is stored in SDL_GetError Initializing SDL if (SDL_Init(SDL_INIT_VIDEO)!= 0 ){ printf ( "SDL not initialized,%s\n" , SDL_GetError); exit (- 1 ); } Initialize display SDL_Window * window = SDL_CreateWindow ( "chip8" , SDL_WINDOWPOS_CENTERED , SDL_...
