Could it be that the tool tries to exploit some vulnerability in the sshd, and just tries to look harmless by using 'test' and 'guest' as usernames? The compromised machine was running an old debian woody installation which had not been upgraded for at least one year, the sshd version string says 'OpenSSH_3.6.1p2 Debian 1:3.6.1p2-10'Does the Debian machine that was compromised have a ``test'' or ``guest'' username?
No.
Also, if it wasn't patched in a year, it may still be vulnerable to this: http://www.cert.org/advisories/CA-2003-24.html
Thanks, I'll have a look at it.
I would tend to think this isn't a 0day kinda vuln, as if it were, he'd be a lot more successful than he seems (unless we're all rooted and don't even know it). But who can tell?
Yes, agreed - I am also convinced it must be something old, and shouldn't be dangerous for reasonably administered machines.
