Dear users,
we have a suspicion there was a database leak containing the user passwords of jabbim.cz, jabbim.com, jabbim.pl, jabbim.sk, njs.netlab.cz, jabber.cz, jabster.pl and jabber.root.cz accounts. The attacker exploited the database using SQL injection bug in our script handling user search, the attack was from Russia. The error has been corrected, but we assume that the attacker gained access to all accounts.

Please change your password in your Jabber / XMPP client. If you also use the same password for other services, change it there as well.

It is very annoying, we apologize for the inconvenience caused.
