Lars,

What you say is true.

For those of you who are interested attached is an strace of this bogus
exploit that I ran in my lab on disposable systems in captive network.

Note, on the parent PID file I edited out quite a bit of repetitive
bogus wait statements, no sense in filling your mailboxes with 400k
lines of crap.

This means that the original poster (gordon last) made it up himself, because he is saying :

i looked at this piece of exploit... it is binary so i'am not sure if
this is a trojan or a backdoor or a virus. but i can't see anything
strange while sniffing the exploit traffic. and i got root on serveral
of my openbsd boxes with that. the bruteforcer seems to be very good.

which is obviously not true. Btw as far as I understand, the troyan code is triggered when
the "exploit" is run with the offset specified, and not in a "bruteforcing" mode.


The trojan seems to be triggered in both cases, providing that the
"bruteforcing" terminates. I haven't test run the code but I did a very
quick reverse of the binary. It connects to the remote sshd but only
sends the key used for descrmbling the trojan code while it pretends
to search for offsets.
