Detailed Analysis

The name of UK Government department Companies House is currently being used in a malware campaign. Emails purporting to be from Companies House are claiming that a company complaint has been levelled against the recipient.

The emails claim that recipients can view more details by opening an attached file. However, the attachment contains a malicious .exe file held inside a .zip file. Opening the attached file can install malware on the user's computer.

Companies House has published the following warning about the malware attack:
We have been made aware that random emails claiming to be from Companies House are being sent. These mails have NOT been generated by Companies House and we strongly advise you not to open any attachments or click any suspicious links within the email, as it may contain a virus. Our customers should be assured that the details we hold have not been compromised.

This campaign is reminiscent of earlier malware attacks that claimed that the Better Business Bureau had received a complaint about the recipient. Again, attachments with the emails contained malware.
