Fake Companies House Emails Contain Malware

by Brett M. Christensen

This story was first published on September 11, 2013

The name of UK Government department Companies House has repeatedly been used in malware campaigns in recent years.

Typically,  the emails, which purport 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, opening the attached file can install malware on the user’s computer. 
Companies House has published the following warning about the malware attack:

We’re aware that some customers have received suspicious emails about company complaints. These emails are not from us.

The warning advises recipients not to open any attachments in the emails.

These campaigns are 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.

Importance Notice

After considerable thought and with an ache in my heart, I have decided that the time has come to close down the Hoax-Slayer website.

These days, the site does not generate enough revenue to cover expenses, and I do not have the financial resources to sustain it going forward.

Moreover, I now work long hours in a full-time and physically taxing job, so maintaining and managing the website and publishing new material has become difficult for me.

And finally, after 18 years of writing about scams and hoaxes, I feel that it is time for me to take my fingers off the keyboard and focus on other projects and pastimes.

When I first started Hoax-Slayer, I never dreamed that I would still be working on the project all these years later or that it would become such an important part of my life. It's been a fantastic and engaging experience and one that I will always treasure.

I hope that my work over the years has helped to make the Internet a little safer and thwarted the activities of at least a few scammers and malicious pranksters.

A Big Thank You

I would also like to thank all of those wonderful people who have supported the project by sharing information from the site, contributing examples of scams and hoaxes, offering suggestions, donating funds, or helping behind the scenes.

I would especially like to thank David White for his tireless contribution to the Hoax-Slayer Facebook Page over many years. David's support has been invaluable, and I can not thank him enough.

Closing Date

Hoax-Slayer will still be around for a few weeks while I wind things down. The site will go offline on May 31, 2021. While I will not be publishing any new posts, you can still access existing material on the site until the date of closure.

Thank you, one and all!
