UPATRE/DYRE MALSPAM -SUBJ: SCANNED IMAGE FROM A XEROX WORKCENTRE

概要

Malicious spam (malspam) delivering Upatre/Dyre has been an ongoing issue for quite some time. Many organizations have posted articles about this malware. Upatre is the malware downloader that retrieves Dyre (Dyreza), an information stealer described as a "Zeus-like banking Trojan". Earlier this year, EmergingThreats reported Upatre and Dyre are under constant development , while SecureWorks told us banking botnets continue to deliver this malspam despite previous takedowns. Botnets sending waves of malspam with Upatre as zip file attachments are a near-daily occurrence. Most organizations won't see these emails, because the messages are almost always blocked by spam filters. Because security researchers find Upatre/Dyre malspam nearly every day, it's a bit tiresome to write about, and we sometimes gloss over the information when it comes our way. After all, the malspam is being blocked, right?
