Millions of people’s info stolen from MGM Resorts dumped on Telegram for free

Miscreants have dumped on Telegram more than 142 million customer records stolen from MGM Resorts, exposing names, postal and email addresses, phone numbers, and dates of birth for any would-be identity thief.

The vpnMentor research team stumbled upon the files, which totaled 8.7 GB of data, on the messaging platform earlier this week, and noted that they “Assume at least 30 million people had some of their data leaked.” MGM Resorts, a hotel and casino chain, did not respond to The Register’s request for comment.

The researchers reckon this information is linked to the theft of millions of guest records, which included the details of Twitter’s Jack Dorsey and pop star Justin Bieber, from MGM Resorts in 2019 that was subsequently distributed via underground forums.

While crooks initially sold those 142 million records on a dark-web marketplace for about $3,000 as a packaged deal, this time the data is freely available on Telegram, which vpnMentor rightly describes as “Much more accessible for even the least tech-savvy people.”

Since that MGM Resorts security breach is two-plus-years-old, the customers’ whose data has been exposed may not expect to be targeted, the cyberexperts explained.

The hotel guests’ data leak comes as automaker General Motors this week confirmed the credential-stuffing attack it suffered last month exposed customers’ names, personal email addresses, and destination data, as well as usernames and phone numbers for family members tied to customer accounts.
