‘Herewith Proof of Payment’ Malware Email

by Brett M. Christensen

Supposedly, this “payment invoice” email contains proof of a recent payment in an attached PowerPoint file.

However, the email is not a genuine payment notification.  Instead, it is designed to trick people into downloading and installing malware.

If you click the link or attempt to open the attachment, a malicious file will be downloaded. If you then open this file, the malware will be installed.
Once installed, the malware may steal sensitive information such as banking or social media passwords, lock the files on your computer and demand that you pay a ransom to receive the “unlock” key, or perform various other malicious functions.

Criminals often use fake invoice emails to distribute malware or trick people into divulging their personal information. Be wary of any unsolicited email that contains information about an invoice or payment that you know nothing about. If you receive such a suspicious email, do not click any links or open any attachments 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,
