New service checks if your email was used in an Emotet spam campaign

The Italian cybersecurity company TG Soft released a new service called "Have I Been Emotet", which allows users to check if a domain or an email address has been used as a sender or recipient of an Emotet spam campaign.

Emotet is malware that spreads through spam emails, which contain malicious documents Word or Excel. When a user opens these documents and the macros are enabled, Emotet will be installed trojan on his computer.

After infecting the victim's computer, Emotet steals the email and transmits it to servers which are under the control of the intruder. This email will be used in future spam campaigns, allowing the malicious agent to make the malicious spam look legitimate so that it can attract more victims.

Over time, the Emotet trojan downloads and installs others malware, As the TrickBot and QakBot, on a victim's computer. These trojans lead to ransomware attacks carried out by their operators Ryuk, Conti and ProLock.

TG Soft told BleepingComputer that their database consists of controlled outgoing emails created by Emotet between August and September 23, 2020. During this period, they collected over 2,1 million email addresses from approximately 700.000 outgoing emails.

To use the new service, one can enter a domain or email address and receive updates on how many times they have been used as a sender or recipient of an Emotet spam campaign.

The "Have I Be Emotet" service provides users with the following information:

  • Real sender: Indicates that the computer using this email account has been compromised and has been used to send spam emails.
  • Fake sender: Indicates that your mail has been stolen and used in spam campaigns.
  • Recipient: Indicates that you have received an Emotet spam email.

If a company has been affected by a cyber attack, one can check if it has been targeted by Emotet spam campaigns, leading to an ransomware attack. Ryuk ransomware, for example, recently attacked leading healthcare provider Universal Health Services (UHS). Using this service, we can see that the UHS domain, uhsinc.com, has been used in recent Emotet campaigns and that the company has received Emotet spam nine times.

If someone uses this service and finds that their email address or domain has been used as a recipient, this does not necessarily mean that you are infected. To be infected, a user must open their email attachments and enable macros before installing the malware. In addition, if a user's domain has users who refer to it as a "real" sender, then it is possible that one of their email domain users is infected and their computers should be thoroughly scanned.
