Has anyone seen a lot of activity around the MacDefender Command and Control Traffic (event ID 13104 and 13108) spyware threat since the introduction of these signatures? I believe first add of these signatures was 248-993 and then updated in 249-1005. I am trying to get a handle on the numerous daily "blocked" events we are seeing for these connections. According to what I know of this malicious behavior - the payload is against the Mac OS only. However, we have no Macs. All these events are happening to PCs. Is it perhaps because a drive-by or web link is bringing our users to the known bad external IPs? Also want to validate that this is indeed a real event and not a false positive - for we are seeing about a dozen of these events a day - never to same internal user. Curious if anyone is seeing any of this activity and thoughts before I open a case.
A couple of cases came into Support regarding the MAC Defender but both are waiting on the customer to provide a pcap of the traffic so nothing conclusive yet. If you can provide a pcap, please go ahead and open a case so that engineering can determine if it is a false positive or not. Thanks.
