$npx -y skills add hypnguyen1209/offensive-claude --skill exploit-developmentUse when turning a memory-corruption bug into a working PoC — stack/ROP, glibc heap & FSOP, format strings, browser/JIT type confusion & UAF, Linux/Windows kernel LPE against ASLR/DEP/CFG/CET/V8-Sandbox
SKILL.md
| 1 | # Exploit Development |
| 2 | |
| 3 | End-to-end weaponization: turn a confirmed bug class into a reliable, version-pinned PoC, then a primitive chain (leak -> R/W -> control flow), against current mitigations. Every cluster pairs the offensive path with detection telemetry and OPSEC. |
| 4 | |
| 5 | ## When to Activate |
| 6 | |
| 7 | - A confirmed vulnerability needs a working, reliable PoC (>=90% success target). |
| 8 | - Userland binary exploitation: stack overflow, heap (UAF/overflow/double-free), format string. |
| 9 | - Defeating modern mitigations: ASLR/PIE, NX/DEP, stack canaries, Full RELRO, CFG, Intel CET shadow stack, V8 Sandbox/pointer compression. |
| 10 | - Browser/JIT engine exploitation (V8 type confusion, addrof/fakeobj, WASM jump-table pivot). |
| 11 | - Local privilege escalation via Linux/Windows kernel memory corruption. |
| 12 | - Converting a crash into a stable read/write/execute primitive chain. |
