Analysis Summary

AgentTesla is known for stealing data from different applications on victim machines, such as browsers, FTP clients, and file downloaders. Agent Tesla collects personal information from the victim’s machine, steals data from the victim’s clipboard, can log keystrokes, capture screenshots, and access the victim’s webcam. It can kill running analysis processes and AVsoftware. The spyware also performs basic actions to check whether it is running on a virtual machine or in debug mode, in an attempt to hide its capabilities and actions from researchers. All the data it obtains is sent in encrypted form via SMTP protocol.
