Analysis Summary
Amadey infects a victim’s computer and incorporates it into a. botnet. The Amadey trojan can also download additional malware. and exfiltrate user information to a command and control (C2) server. Moreover, it can engage the victim’s system. The threat actor sent spam emails that reference a package or shipment. Many of the emails claim in the subject line that the package or shipment is from the shipping company DHL. For example, one subject line is “You have a package coming from DHL.” The bodies of all of the emails we observed in this campaign are blank. Each email has a ZIP attachment containing a Visual Basic Script (VBS) file. Each file name for the ZIP files is a series of numbers separated by an underscore, such as 044450_64504154.zip. The VBS files have the same name as their ZIP file, except they have the VBS extension rather than the ZIP extension.
