The hacker responsible for one of the world's largest digital coin heists has returned nearly all of their more than $610m (440m) haul, reportedly saying they did it for fun" and to expose a vulnerability.

The victim, Poly Network, which until Tuesday's heist was a little known peer-to-peer cryptocurrency platform, said all of the funds except for $33m-worth of the digital coin Tether, which were frozen earlier in the week, had been transferred to a wallet controlled by both the platform and the hacker.
