Modern Exploit Mitigations & Bypasses
Understand the defenses that stand between a vulnerability and a working exploit: ASLR, DEP/NX, stack canaries, CFG, and the high-level ideas behind bypassing them.
Why Exploits Got Harder
You can identify binary vulnerabilities, fuzz for bugs, and understand exploit primitives. Modern systems add mitigations that turn an easy bug into a hard one.
Knowing these defenses tells you what a working exploit must overcome.
Data Execution Prevention (DEP/NX)
DEP (a.k.a. the NX bit) marks memory as non-executable. Code injected onto the stack will not run.
This killed classic 'shellcode on the stack' attacks and pushed exploiters toward code reuse.
