AT&T ‘You Have a New Voice Mail’ Malware Email

by Brett M. Christensen

Outline

Message purporting to be from telecommunications company AT&T claims that a new voicemail could not be delivered to the recipient. The email includes an attached file that supposedly contains the voicemail. 

Brief Analysis

The message is not from AT&T and the attached file does not contain a missed voicemail. Instead, the attachment harbours a malicious .exe file hidden within a .zip file. Opening the .exe file can install malware on the user’s computer.

AT&T Voice Mail Malware Email

 

Detailed Analysis

According to this email, which claims to be from telecommunications giant AT&T, the recipient has a new voicemail. The message advises that the voicemail could not be delivered. The message includes an attached .zip file that supposedly contains a copy of the lost voicemail.

However, the message is not from AT&T and the attached file does not contain an undelivered voicemail as claimed. In fact, hidden inside the attached .zip file there is a malicious .exe file.
If opened, the .exe file can install malware on the user’s computer. Typically, such malware can harvest sensitive personal information from the infected computer and relay it to servers operated by online criminals. It may also allow the criminals to control the compromised computer from afar and download and install even more malware.

This attack is similar to another malware distribution that claims that WhatsApp users have a new voicemail waiting. Clicking the “Play” button in the bogus email will open a malicious website that harbours malware.

And, AT&T customers have been targeted a number of times in the past via both phishing and malware emails.

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,
