Summary
Buffer-overflow-exploits are a type of cybersecurity threat where attackers take advantage of a software bug that allows them to overwrite parts of a computer's memory, potentially gaining control over the system. Understanding how these exploits work is crucial for anyone interested in protecting computers and networks from malicious attacks.
- Review code carefully: Always monitor and test your software for areas where data input could exceed allocated space, as these are common targets for buffer overflow exploits.
- Learn modern protections: Familiarize yourself with security features like address space layout randomization (ASLR) and stack canaries, which help prevent attackers from using buffer overflows to compromise systems.
- Practice hands-on: Use simulated environments or vulnerable sample programs to safely explore how buffer overflow exploits work and how defenses operate in real-world scenarios.

I created a walkthrough with vulnerable binaries and source code to teach the basics of buffer overflows and exploit development. This blog with TCM Security goes over the very first level showing a basic stack overflow. I'll be releasing future levels that cover more advanced topics such as writing shellcode and chaining together vulnerabilities to bypass protections like ASLR and stack canaries. https://lnkd.in/gpW87mqF
