R. Z.
This flashcard set delves into the intricacies of exploit programming at a university level, focusing on concepts like buffer overflows, shellcode, and the Stored Instruction Pointer (SIP). It covers techniques such as using NOP sleds to ensure successful execution of shellcode, determining the distance to the SIP, and finding the offset within the buffer. The set is particularly useful for students and professionals in cybersecurity, providing practical insights into creating and understanding buffer overflow exploits, which are crucial for identifying and mitigating vulnerabilities in software.

What are the pitfalls of exploit programming?

  • Always check the settings
    • ASLR on/off
    • Execstack on/off
  • RIP (EIP) not really overwritten?
    • Check if it is not too much overflow
    • Or too little
  • "cannot insert breakpoint"
    • It looks like it works! Disable breakpoint
  • "Starting program /bin/dash"...
    • GDB is confused. Load the challenge file again
  • Exploit works only in GDV
    • That's normal. Enable core files, and start debugging
