About $33m in frozen coins yet to be returned as still-unidentified hacker claims attack was carried out ‘for fun’ to ‘expose the vulnerability’ of platform
Hackers behind one of the biggest-ever digital coin heists have now returned nearly all of the $610m-plus they stole, the cryptocurrency platform targeted this week by the attack says.
The Poly Network platform, which was little known before Tuesday’s heist, on Thursday declared the hacker on Twitter to be a “white hat”, referring to ethical hackers who generally aim to expose cyber vulnerabilities, upon the return of the funds.
