KrebsOnSecurity recently reviewed a copy of the private chat messages between members of the LAPSUS$ cybercrime group in the week leading up to the arrest of its most active members last month. The logs show LAPSUS$ breached T-Mobile multiple times in March, stealing source code for a range of company projects. T-Mobile says no customer or government information was stolen in the intrusion. LAPSUS$ is known for stealing data and then demanding a ransom not to publish or sell it. But the leaked chats indicate this mercenary activity was of little interest to the tyrannical teenage leader of LAPSUS$, whose obsession with stealing and leaking proprietary computer source code from the world’s largest tech companies ultimately led to the group’s undoing.

Crooks have stolen tens of millions of dollars and other valuable commodities from thousands of consumers via “SIM swapping,” a particularly invasive form of fraud that involves tricking a target’s mobile carrier into transferring someone’s wireless service to a device they control. But the U.S. Federal Communications Commission (FCC), the entity responsible for overseeing wireless industry practices, has so far remained largely silent on the matter. Now, a cadre of Senate lawmakers is demanding to know what, if anything, the agency might be doing to track and combat SIM swapping.

Who Owns Your Wireless Service? Crooks Do.

Incessantly annoying and fraudulent robocalls. Corrupt wireless company employees taking hundreds of thousands of dollars in bribes to unlock and hijack mobile phone service. Wireless providers selling real-time customer location data, despite repeated promises to the contrary. A noticeable uptick in SIM-swapping attacks that lead to multi-million dollar cyberheists. If you are somehow under the impression that you — the customer — are in control over the security, privacy and integrity of your mobile phone service, think again. And you’d be forgiven if you assumed the major wireless carriers or federal regulators had their hands firmly on the wheel.

Prosecutors in Northern California have charged two men with using unauthorized SIM swaps to steal and extort money from victims. One of the individuals charged allegedly used a hacker nickname belonging to a key figure in the underground who’s built a solid reputation hijacking mobile phone numbers for profit. According to indictments unsealed this week, Tucson, Ariz. resident Ahmad Wagaafe Hared and Matthew Gene Ditman of Las Vegas were part of a group that specialized in tricking or bribing representatives at the major wireless providers into giving them control over phone numbers belonging to people they later targeted for extortion and theft.
