Outsider Enterprise has financially scammed “hundreds of thousands of victims” with losses “estimated in the millions.” The group deployed 9,000 fake websites, one million fraudulent web domains, and 2.5 million texts sent to Android users in a two-week period, according to Google.

The company said, “55,000 spam texts were flagged by Android users in just two weeks this past May — that’s more than two text spam complaints a minute.”

Google said it uses “AI-powered tools to fight AI-powered scams,” which enable the company to detect scams and alert users of suspicious calls and text messages, leading to the interception of more than 10 billion scam messages a month.

The company said it has been collaborating with AT&T, T-Mobile, and Verizon to block the scam text messages, and said it is coordinating with the FBI.
