More PATH fallout. Who decided this was a good idea?

Actually, yes. There are environments in which an administrator may set
up heuristics to determine whether a user is attempting to probe the
system for vulnerability. In the systems like this I've seen, one very
common action to note is failed attempts by users to execute processes
in /sbin or /usr/sbin. Seeing the same user attempt to execute every
binary in one of those folders could be a clear sign that they are
probing for misconfigurations to take advantage of.
