Sophos has noticed a few days ago that spammers are sending emails which has subjects that contain either the the word ‘Aliens’ or ‘UFO’. These email subjects also contain a broadcasting company such as CNN and BBC.

Some examples of these subjects are:
CNN: Aliens send us cartoon messages!
CNN: Space UFO found at Jupiter orbit!

The blog article at Sophos notes that it contain attachments which are detected as Troj/VidRar-Fam. Those attachments contain executables which are detected as Troj/Agent-HNY.

The malware authors reverted back to subjects about videos.
