INCIDENT: Exponential Rise in IRS-Themed SMS Phishing Attacks in U.S.

The Internal Revenue Service (IRS) warned Americans of an exponential rise in IRS-themed text message phishing attacks trying to steal their financial and personal information in the last few weeks. "In recent months, the IRS has reported multiple large-scale smishing (MMS/SMS/text scams) campaigns targeting taxpayers, that have delivered thousands – and even hundreds of thousands – of IRS-themed messages in hours or a few days, far exceeding previous levels of activity."

The Federal Communications Commission (FCC) issued a similar warning in July 2022. According to the U.S. communications watchdog's Robocall Response Team, these phishing messages (or robotexts as the FCC calls them) will hit billions of phones every month.
