Uwe Hermann | A slightly paranoid Debian developer

Somebody got hacked by a complete fool without any sort of clue. What the attacker (i.e. script kiddie) tried to do (and how he failed) is actually quite funny IMHO.

E.g., after trying

rm -rf bash_history

(notice the missing dot in the filename) he wanted to be really sure and issued

unset HISTFILES

Surely, his tracks are perfectly covered now. Nobody will ever know.
