Those behind the massive WannaCry ransomware attack earlier this year are making moves to protect their windfall.
According to Elliptic's data, the hackers amassed more than $144,000 worth of bitcoin in the three accounts. But on Wednesday evening, they quickly emptied them.
A Twitter bot set up by Quartz to monitor the WannaCry-affiliated bitcoin wallets showed that the owners of the accounts started withdrawing the money around 11:10 p.m. ET last night in increments of around $20,000 to $30.000. After 15 minutes and seven withdrawals, the accounts were empty.
