Hi guys,

 

 

 

To my utter frustration there are some people who seem to be in a mood to destroy my Christmas spirit by hacking our gaming server.

 

I am a "moderate" level Linux user but the things they seem to have messed up are above my level of expertise.

 

Any avid Linux guru who is willing to have a look please drop a line..

 

 

 

Cheers

I've been helping @ScuL tonight to migrate to a new server I'm setting up.

The server was compromised via dirty cow - dodgy .php script by the looks. They disabled all logging on the server (including bash history) and hidden all evidence of what has been done. In ScuL's defense he was following best practices with most things but had way too much sitting on one server and whilst it was patched for most things (including being SELinux enforced) it wasn't patched against Dirty Cow with its impressive uptime of 326 days. I've been going through dumping everything off and migrating them to a new Ubuntu VM sitting on a VM host I have space on for now.

 

Without going into too many details this site handles quite a few thousand hits per day (seeing on average ~200/sec hits to the new server).

 

Quite a big job to do but I can't have somebody lose a server on Christmas day to some script kiddie especially since they just did a release of what they're working on. It sucks as it is losing a production server especially hosting a busy site but the timing on this really blows too. Christmas eve, after a release (which seems many people are excited about) and dealing with many GB's of data, multiple MySQL databases and a forum with other peoples hard work.

 

Anyway with most of the hard work out of the way I am sure ScuL can sleep easier now and enjoy Christmas.
