RapidFax Malware Email

 

Detailed Analysis

This message, which purports to be from online fax to email service RapidFax, claims that a fax has been received and can be viewed by opening an attached file. The email includes a list of details about the supposed fax along with the RapidFax logo and links to associated websites.

However, the email is not from RapidFax and the attachment does not contain a fax as claimed. In fact, the attachment contains a .zip file that harbours a trojan. 
Unzipping the attached file reveals a malicious .exe file. If the user proceeds to open this .exe file, the trojan will be installed on his or her computer.

Typically, such trojans can make contact with remote servers controlled by cybercriminals, harvest sensitive information from the compromised computer and download further malware.

If you receive one of these emails, do not open any attachments or click any links that it may contain.

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!

Brett Christensen,
