Troj/Agent-XNN is a dangerous backdoor Trojan. Using Troj/Agent-XNN, criminals can gain access to your computer and carry out a variety of malicious tasks. For example, a Troj/Agent-XNN infection can be used to install other malware on the victim's computer or to steal private information stored on that computer. Troj/Agent-XNN commonly spreads via email scams, usually in the form of a malicious email attachment contained in a ZIP archive. Troj/Agent-XNN in particular has been linked to an email spam scam that is distributed in the form of a fake Facebook notification. To prevent Troj/Agent-XNN infections, ESG malware analysts advise protecting your computer with advanced security software and making sure that your anti-spam filter prevents email messages containing Troj/Agent-XNN from ever reaching your email inbox in the first place.

How the Troj/Agent-XNN Email Scam Works

A Troj/Agent-XNN infection will usually begin with an email message claiming that a Facebook friend added a photo of you to their profile. This notification is similar to Facebook's real email notifications, so it can be easy to be tricked by it if you are an inexperienced computer user. However, unlike Facebook's real email notifications, this malicious email will try to convince you to download an attached ZIP file. This ZIP file is actually the Troj/Agent-XNN Trojan, despite the fact that it will be named differently. Troj/Agent-XNN will usually be disguised as a ZIP attachment with the name 'New_Photo_With_You_on_Facebook_PHOTOID[random number].zip' and will be included in an email message claiming that a Facebook friend added a photo of you to an album. Facebook does not allow computer users to view photos as attachments, so this is definitely a scam, despite the fact that the email message spoofs a Facebook-related email address and it uses language, logos and design that are very similar to official Facebook notifications.

The Troj/Agent-XNN Scam is Only One of Many Fake Facebook Email Scams

ESG malware analysts have reported previously on numerous other email scams that disguise themselves as Facebook notifications. Due to the fact that this social network has a high number of members that are relative newcomers to the Internet and that computer users are likely to want to see their pictures, these have proven to be quite effective at distributing malware. It is also important to avoid these kinds of email messages if they contain embedded links, since previous versions of this scam use links to take computer users to attack websites rather than including malicious file attachments.
