Intrusion Prevention System (IPS) Log shows local DNS hosts as Attacker and forwarders on the DNS hosts as Attack Targets

Hi Everybody,

Intrusion Prevention System (IPS) Statistics Log shows local DNS hosts as Attacker and forwarders on the DNS hotst as Attack Targets?
The following attack rule is being applied INDICATOR-COMPROMISE Suspicious .win dns query.

Is there a way to solve this "problem"?

Regards, Stephan

  • Hoi Stephan,

    The DNS log in your local name server should show which client is requesting resolution for a .win FQDN.  This is a sign that that client has a malware infection or is visiting an infected site.
