Zbot Spam Campaign Continues

by Aljerro Gabon (Anti-spam Research Engineer)

A slightly modified Zbot spam campaign currently making rounds pretend to come from the IT support of various companies. It informs users that a security update in the mailing service caused changes in their mailbox settings. They are instructed to open the ZIP attachment and run the .EXE file, INSTALL.EXE to supposedly apply the changes. Trend Micro detects this as TROJ_FAKEREAN.CF.

When executed, this Trojan accesses http://{BLOCKED}nerkadosa.com/xIw1yPD0q5Gb8t0br4×6k5sk to download another malicious file detected as TROJ_FAKEREAN.BI.
