The IP has been automatically blocked for a period of time. For an IP to be blocked, it needs 
to have made several failed logins (ssh, imap....), tried to log in for an "invalid user", or have
triggered several 5xx-Error-Codes (eg. Blacklist on email...), all during a short period of time.
The Server-Owner configures the number of failed attempts, and the time period they have 
to occur in, in order to trigger a ban and report. Blocklist has no control over these settings.


Please check the machine behind the IP 31.130.230.71 (31.130.230.71) and fix the problem.

230.71 had an ssh scanner installed in opt, set to run at boot in /etc/rc.local.

Alessandro is going to reinstall the Rpi and disable any logins except for those with publickeys.

It is not known how the attacker was able to gain access to a root shell.
