Find SUID Binaries

A security audit turned up a suspicious setuid-root binary hiding on this host — a classic privilege-escalation backdoor. Hunt down every SUID binary, identify the planted one (it lives somewhere it has no business being), record its full path to /root/case/suid.txt (just that one path; its own ls -l line is accepted too, the whole SUID listing is not), then neutralize it by removing the setuid bit.
