T-Mobile data breach: What’s the Bitcoin connection

In an interesting turn of events, telecom giant T-Mobile is allegedly looking into a massive data breach that is said to involve personal data from more than a 100 million people.

As per recent reports, T-Mobile is probing into a forum claiming to be “selling a mountain of personal data,” in exchange for Bitcoin. “We are aware of claims made in an underground forum and have been actively investigating their validity, we do not have any additional information to share at this time,” a T-Mobile spokesperson told

アメリカの携帯キャリア、T-MOBILEのサーバーに侵入し、1億人分の個人情報を手に入れたから、3,000万円をよこせと連絡が入ったそうだ。まだ本当に情報が流出したのか調べている最中なのに、大手メディアはすでに報道しちゃっている。これで株価暴落だね。https://t.co/7kVm3LcCus

The “seller” reportedly revealed that the said data included social security numbers, phone numbers, names, physical addresses, unique IMEI numbers, and driver’s licenses information. The seller mentioned, “T-Mobile USA. Full customer info,” when discussing the same with media.

As far as the demand is concerned, the seller asked for 6 BTC, in exchange for a portion of data, containing 30 million social security numbers and driver licenses. This amounts to around $287,000, at the time of writing. However, seller specified that the remainder (of the data) will be sold privately. Referring to T-Mobile’s swift response to the breach, the seller responded,

“I think they already found out because we lost access to the backdoored servers.”

Unfortunately, this wasn’t the first time that T-Mobile was a target of a cyber-security scandal. According to findings

, T- mobile was sued by a victim who lost $450,000 in Bitcoin in a SIM-swap attack. The lawsuit was filed against T-Mobile on February 8, in the Southern District of New York, by plaintiff Calvin Cheng.
