Can't post anything: "The connection was reset"

[backend]

I will keep an eye on this for the next few days to see if the code will somehow come back and let you guys know. If not, I will mark this topic solved.

ooh... that is sneaky...

decode the base64 - it points to botstatistic...


So - looks like you were hacked.
1- start checking *ALL* files and directories. Hackers rarely drop a single payload.
2- figure out WHEN it happened. Look at the timestamp on the modified files (before you removed the code yourself) - then ask your host to help get the server logs for that time period.
3- report with the server logs to the security form
http://www.simplemachines.org/about/smf/security.php
and you can send the server logs to [email protected]

when you file the report, indicate the smf version, mods installed and whether you have any other software installed on the same server.
