SUID Binary Privilege Escalation
A stray SUID bit on the wrong binary is an instant root. Drill enumerating and abusing SUID binaries until it's automatic.
Enumerate SUID-root binaries with `find / -perm -4000 -type f`, recognize the one that doesn't belong among the system defaults, and abuse it (a SUID shell with `-p`, `find -exec`, and friends) to read the root flag.
Each rep seeds a different SUID binary, so you learn to spot the anomaly rather than recall a single trick.
How the attack works
- List every SUID-root binary on the host.
find / -perm -4000 -type f 2>/dev/null - Pick out the binary that isn't a normal system default — that's the seeded flaw.
- Abuse it with its GTFOBins SUID payload to run as root (note the -p to preserve euid).
find . -exec /bin/sh -p \; -quit - Read the root-owned flag.
cat /root/flag.txt
On PwnKata the binary, account, and paths change every rep — so you drill the recognition, not this exact command.
