Recent breaches of MGM’s casino systems “were probably carried out by teens and young adults who have allied themselves with one of the world’s most notorious ransomware gangs,” writes the Washington Post’s technology reporter.
Their alliance with the “Scattered Spider” group is described as “part of a trend that has alarmed security experts and defenders of corporate computer networks.” The group is said to be “very active in the past two years, targeting large companies via stolen employee credentials and tricks such as convincing tech support employees that they have been accidentally locked out of their computers and need a new password.”

And they extorted Western Digital and other technology firms after stealing internal data before heading for the jackpots in Las Vegas. But their willingness to deploy crippling ransomware while demanding money is a major escalation, as is their choice of a business partner: ALPHV, a hacking group whose affiliates include members of the former Russian powerhouses BlackMatter and DarkSide, the groups responsible for the Colonial Pipeline hack that awoke Washington to the national security risk of ransomware. ALPHV provided the BlackCat ransomware that the young hackers installed in the casinos’ systems…
[According to new research presented Friday at the LABScon security conference] they came together through crimes enabled by SIM-swapping, which usually involves convincing phone company employees to hand over control of someone else’s phone number.

Worse, the researchers said, they have now attracted recruiters for the Russian gangs who want to combine their business savvy with the techniques and local knowledge of the native English speakers.
