Technical Details

Trojan-Downloader:W32/Kavala variants are distributed via file attachments to e-mail messages. The malware itself is a Windows executable program compressed into a ZIP file that is attached to the e-mail messages.

Both the ZIP file and the contents of the email follow typical social engineering patterns (e.g, using file names such as RE: Payment Pending or RE:Attachment Shipping Document) to deceive and lure users into extracting and running the attached program.

When the trojan-downloader program contained in the ZIP file is extracted and run on a user's machine, it will attempt to contact a remote server and download additional files onto the affected machine.
