A hacker called up T-Mobile and convinced the customer service representative that he was Jared Kenna. T-Mobile believed the hacker and transferred Kenna's phone number from T-Mobile to another carrier.
Once the hacker had Kenna's phone number he took over about 30 of Kenna's accounts, which had been protected with 2-factor authentication.
The accounts included "two banks, PayPal, two bitcoin services — and, crucially, his Windows account, which was the key to his PC."
In short order the hacker stole "millions" of dollars worth of Kenna's bitcoin.
