Path traversal in filename
One upload = full shell ๐ #pentesting#websecurity
CTF mindset vs real world pentesting:
CTF: The vulnerability IS there, find it
Real world: It might not be there at all
CTF: Fast and dirty
Real world: Document everything
Both valuable but different skills. ๐ฎ #pentesting#cybersecurity
API pentesting is where the money is right now.
BOLA (Broken Object Level Authorization)
Mass assignment
Excessive data exposure
No rate limiting
Endpoints hidden in mobile apps
Start learning API testing. ๐ #pentesting#api
Bug bounty tip: Read other people's writeups daily. You'll learn patterns and techniques that took someone hours to figure out. Stand on shoulders of giants. ๐ #bugbounty#cybersecurity
OSCP advice nobody tells you:
Sleep before the exam
Time management is the real test
Enumeration > exploitation
If you're stuck for 2 hours move on
Take notes AS you go
Good luck to anyone taking it ๐ #OSCP#pentesting
JWT vulnerabilities are sneaky.
alg: none bypass
Weak HMAC secrets (brute force with hashcat)
Algorithm confusion (RS256 to HS256)
Sensitive data in payload
Never trust client-side tokens blindly. ๐ #websecurity#pentesting
Privilege escalation on Linux checklist:
