Krebs points out the potential initial culprit in gaining credentials to access the CareFirst network and data may have been similar to the Doppelgänger attacks Proficio discussed in our April 23, 2015 blog on ‘Wire Transfer Scams on the Rise’.  Wiki describes a Doppelgänger as ‘a double or evil twin… in some traditions (portrayed) as a harbinger of bad luck’. In the security community a Doppelgänger domain impersonating another domain name to trick or re-direct user’s to go to the site and enter private information or download malware. An example of a Doppelgänger for CareFirst[dot]com would be registered as CareFiirst[dot]com.

As with any Breach we read about these days, it merely starts with a single malicious event considered an incident that compromises a network perimeter or device and then propagates through a series of further malicious events inside an organization through what we call a Kill Chain of incidents. An ultimate Breach, typically a loss or exfiltration of data, almost always is predicated by a series of these incidents to gain higher level credentialed access and data gathering. The test of a great security program is to be able to correlate these incidents together to discover a pattern in the Kill Chain and block the next step before a breach occurs. When you see announcements of breaches where the attacker has been inside the network propagating for some time, it usually means an organization needs to re-evaluate and adjust the Security Operations Center threat detection program or call on a SOC-as-a-Service organization as a long term partner.
