Technical Details



This trojan-downloader is distributed as a file attachment to spam e-mails. The attached programs are typically labelled using legitimate-sounding document names, such as 'invoice', as a simple form of social engineering.

On execution of the attached file, the trojan-downloader will attempt to install itself onto the machine, then contact a remote server for additional files and/or instructions.
