WASHINGTON — The Internal Revenue Service and Security Summit partners today warned the public of a surge of fraudulent emails impersonating the IRS and using tax transcripts as bait to entice users to open documents containing malware.
The scam is especially problematic for businesses whose employees might open the malware because this malware can spread throughout the network and potentially take months to successfully remove.
This well-known malware, known as Emotet, generally poses as specific banks and financial institutions in its effort to trick people into opening infected documents. The Summit partnership of the IRS, state tax agencies and the nation’s tax industry remind taxpayers to watch out for this scam.
However, in the past few weeks, the scam masqueraded as the IRS, pretending to be from “IRS Online.” The scam email carries an attachment labeled “Tax Account Transcript” or something similar, and the subject line uses some variation of the phrase “tax transcript.”
These clues can change with each version of the malware. Scores of these malicious Emotet emails were forwarded to email@example.com recently.
The IRS reminds taxpayers it does not send unsolicited emails to the public, nor would it email a sensitive document such as a tax transcript, which is a summary of a tax return. The IRS urges taxpayers not to open the email or the attachment. If using a personal computer, delete or forward the scam email to firstname.lastname@example.org. If you see these using an employer’s computer, notify the company’s technology professionals.
The United States Computer Emergency Readiness Team (US-CERT) issued a warning in July about earlier versions of the Emotet in Alert (TA18-201A) Emotet Malware.
US-CERT has labeled the Emotet Malware “among the most costly and destructive malware affecting state, local, tribal, and territorial (SLTT) governments, and the private and public sectors.”
