A new mass-mailing worm is making its rounds by promoting a Hallmark e-Card, McDonald’s Coupon, or Coca Cola Christmas Promotion.
Full worm description (manual analysis) is provided here.
Automated threat analysis generated this write-up.
ThreatExpert automation tricked this threat with several intentionally implanted fake email contacts (such as Rusty Carr, Easton West, Justin Case and others). As soon as this threat picked up one of those contacts and attempted to submit an email to that person via the ThreatExpert’s emulated network services (with no traffic ever leaving the sandbox), it was immediately classified as mass-mailer.
