Technical Details


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