[Security] Mailserver 'brute force' password attacks

Added by Carsten Rose about 7 years ago

Dear all

we have been attacked since Tuesday (6.6.17) by brute force password attacks on our mailserver. Some user accounts have been locked automatically due to too many failed logins.

  • The attacker IP addresses are now blocked.
  • All affected accounts has been enabled again.
  • No passwords has been cracked.

Thanks

Carsten
