Should I wonder what is going on? remove the block and tell daddy(report this) or just start blocking all ev1 ips that arent from techs ips.
Full Version: bfd attack to my ssh from ev1 user
I definitly recommending sending your logs in to Abuse so that we can address the issue with that specific server customer.
It was just an exploited server, there are plenty of them floating around there. The thing is they do not even require root and a simple php exploit is capable of running the attacks. Until somebody notifies abuse it will probably stay online. I don't recall off hand but for those sorts of attacks they usually get 24 - 72 hours to fix it or face the box being disconnected.
As Aaron said email abuse@theplanet.com with all the information you have to get the ball rolling on that.

thanks guys, done.
I also ended up blocking a butt load of server ips ranges for ev1 users/servers accounts.
no reason to let these idiots near my toyz.

Can't you just change the SSH Port?

My server gets scanned and adds ev1 server/and everyones internet dial up users all the time, i have ssh on a new port and it still gets scanned like mad, with BFD they just get auto added and I share my ban ip list with all my servers , problem solved. people using things like nmap find my ports without any effort but once they try it , they get blocked.
I just like to let theplanet/ev1 know that 5 or more servers/accounts a week are hacked at least, and are being used to do bad things. abuse@ is my new friend.

And we like to know about them!
The nature of this attack is simple probability. Attackers use a user/password list to try and get access to a server, then use those compromised accounts to scan for more. This is why sys admins need to ensure their users are using good passwords.
