Someone's done an interesting analysis of a Linux box that got compromised and used as a zombie box. If you're into Linux it's worth a read to see how a box can get owned and what to look out for. |

Interesting but just seems what every other trojan/backdoor problem regardless of OS would do. Install itself, add hacked system files, etc. I'm wondering how it got comprimised in the first place though, that'd be the most interesting information.
Was it a simple root password, stupid sysadmin giving out free shell accounts or so on.. |

Sendmail (prior to Sendmail 8.6.10) was no doubt the cause of this hack.

i use to keep a little tar ball of ls, ps, top, netstat and ifconfig to investigate this kind of thing. a md5 on those binaries would show up inconsistancies since most root kits replace them instead of modifying the kernel as it is a quicker and easier path. my money is it was from php-nuke or some such dodgey CMS. |

I have experienced a top leveling hacking group at work from the wrong side. Starting around 7pm on a Friday, all finished by Monday. They got in via a new BIND vulnerability, using a hacked webserver at the Argentinian version of Telstra. Then procedign to go after security and military server in Canada and the US.
First I knew of it was a phone call from the AFP on the Thursday after it, in conference with the DNDCF (or some acronym like that ie. Canadian Military), Pentagon and FBI. Long story hours on the phone. Then a day latter some guys from Cert AU rang and helped me to clean it up and they got the info they needed to work out how they cracked BIND. *shrug* |
