As
2012 was winding down, the CrowdStrike Intelligence team was in hot
pursuit of an adversary who was leveraging a Strategic Web Compromise
(SWC) attack using an exploit for an at-the-time unpatched vulnerability
(CVE-2012-4792). This attack was a harbinger of what was to follow
throughout 2013. These attacks, commonly called “watering holes”, do not
rely on social engineering and weaponized documents to victimize their
prey. Instead, sites known to be of interest to the victim are seeded
with exploits leading to droppers intended to implant the system of the
unsuspecting visitor. In Q1 2013, the CrowdStrike Intelligence team
warned our threat intelligence customers of the impending shift in
targeting to this attack scenario. This estimative analysis factored in
many pieces of intelligence that were collected and analyzed by the team
and used to develop indications and warnings.
