Agent Tesla: The Punches Keep Coming

This Cofense strategic analysis examines five years of email campaign data delivering Agent Tesla, a .NET-based Malware-as-a-Service used as a keylogger and information stealer. The report highlights rising yearly volumes (with a major surge in 2021), consistent Q3–Q4 seasonality, and a Q1 2024 increase attributed in part to improved detection; it also summarizes Agent Tesla’s capabilities and exfiltration options (FTP, SMTP, web panels, Telegram) and projects continued growth if trends persist.
