Analysis Summary
TrickBot – a windows-based banking trojan – makes its first appearance in 2016. It targets sensitive data and serves as a distribution point for additional malware. Malspam operations are the most common way for Trickbot to propagate. These tactics send unsolicited emails that link consumers to harmful websites where they may download malware or deceive them into opening malware through an attachment. Other malware can potentially release TrickBot as a secondary payload. Trickbot is used in malspam operations that imitate recognizable brandings, such as invoices from accountancy and banking businesses. An attachment, such as a Microsoft Word or Excel document, is usually included in the emails. When the user opens the attachment, it will request them to activate macros, which will start a VBScript that will download the malware via a PowerShell script.
