Ik kreeg vanmiddag een mail van Strato dat mijn VPS misbruikt wordt tbv hacking.
Dear Mr. / Mrs.
We inform you that third parties let us know that your server with the hostname < hxxxxxx.stratoserver.net> has a security issue. Your server attacks the systems of these third parties via hacking and scanning. Please see the log-file at the end of this e-mail for details.
This process affects the technical infrastructure of the STRATO AG on an unacceptable manner and is therefore contrary to the normal operation conditions of our terms and conditions. This information can always be found following this link: http://strato.de/agb/index.html
It is very likely that a third party has access to your server. Please be aware that hacking the systems of others is a violation of the law.
Now we need you to fully check your server and take measures so that the hacking stops. Also we like you to let us know what you have done to solve this issue.
If you harbour the suspicion that a third party has compromised your server, we recommend that you back up your data, check it for manipulation (backdoors) and reinstall the server.
Wat er precies aan de hand is weet ik niet.
Belangrijker nu is welke stappen ik ondernemen moet/kan?
