Michael Tremplin is a Puerto-Rico based entrepreneur and CEO of TransformGroup. He is as well a co-founder of a group of bitcoin investors and a digital currency fund. No, he claims that he has lost 224 mln USD in cryptocurrency after the hacking attack.
He filed a 96-pages complaint to a Californian Court, where he mentioned two major theft episodes. AT&T, which subscriber he has been, didn’t managed to protect his identity, and as the result, hackers could get access to his financial data and have stolen a huge sum of money.
Specialists believe, he fell a victim of so-called SIM swapping process, when a telecom provider transfers the target`s phone number to a SIM card held by the attacker. That allows even to handle the two-factor identification. SIM swapping is a very easy thing to perform and has become a very popular scam. Cryptocurrency accounts are its main target.
