Topic: securuty : a hacker's attack on my sme server 5.1.2

[doumebzh]

Hello
After problems http on my server, I open a ssh shell from outside my local network. I was looking at new files unknown on /, an then I see like a chat on my shell (see above what said the hacker).
Anyone has an idea on the way he attacked my server, an how I can avoid that anymore??

5.1.2 is very old, and all users have been recommended to upgrade for a long time now. It is no big suprise that the server has been compromised. You'll need to do a fresh install, of an up to date version.
