Technical Details

Trojan-Downloader:W32/Upatre typically arrives in a file attached to a spam email message. The contents of the email message are usually designed to lure the user into running the attached file, which then installs the Upatre downloader.

Upatre may also be distributed as the payload of another malware, such as the Pitou botnet (Pitou whitepaper, PDF).

Once installed, the downloader silently connects to a remote server and downloads additional files onto the system.
