McAfee Labs have observed a new phishing campaign that utilizes macro capabilities available in Microsoft PowerPoint. In this campaign, the spam email comes with a PowerPoint file as an attachment. Upon opening the malicious attachment, the VBA macro executes to deliver variants of AgentTesla which is a well-known password stealer. These spam emails purport to be related to financial transactions.
AgentTesla is a RAT (Remote Access Trojan) malware that has been active since 2014. Attackers use this RAT as MASS(Malware-As-A-Service) to steal user credentials and other information from victims through screenshots, keylogging, and clipboard captures. Its modus operandi is predominantly via phishing campaigns.
