'White Hat' Hacker Returns Most Of $600 Million Crypto Tokens Taken: Poly Network

Poly Network added that the tokens were transferred to a multi-signature wallet controlled by both the platform and the hacker.

Hackers behind one of the biggest ever digital coin heists have now returned nearly all of the $610 million-plus they stole, Poly Network, the cryptocurrency platform targeted earlier this week by the attack, said on Thursday. The platform, which was little known before Tuesday's heist, declared the hacker on Twitter as a "white hat," referring to ethical hackers who generally aim to expose cyber vulnerabilities, upon the return of the funds. Poly Network, which facilitates peer-to-peer token transactions, added that the tokens were transferred to a multi-signature wallet controlled by both the platform and the hacker. The only remaining tokens yet to be returned are the $33 million in tether stablecoins frozen earlier in the week by cryptocurrency firm Tether, Poly Network said.
