‘Attached is Your Credit Note’ Malware Emails

by Brett M. Christensen

Emails claiming to include a ‘credit note’ in an attached file are currently hitting inboxes. The emails specify an invoice number for the supposed credit note. The emails also include a value for the supposed invoice along with the name of the company that purportedly sent the message.

However, the emails are not legitimate and they were not sent by the companies they name. In fact, the messages include a malicious file in the attached .zip file. 
If opened, the file can install malware on your computer. Once installed, the malware may collect banking, email, and social media login credentials from your computer and send them to online criminals. The criminals can use this stolen information to hijack your online accounts.

The greeting name, the name of the sending company, the invoice number, the invoice amount, and the specified currency may vary in different versions of the emails.

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

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,
