Transactions publicly saved on the blockchain display an handle belonging to Poly’s hacker started returning the about $610 million in stolen cryptocurrency assets via a number of transactions early Wednesday.
So far, Tom Robinson, the main scientist at blockchain analytics firm Elliptic, suggests Poly has retrieved all the $267 million in ether and $252 million in binance cash stolen, and approximately $55 million in tokens pegged to the U.S. dollar.

Among early Wednesday morning and Thursday afternoon, the seemingly unabashed hacker has been leaving notes embedded in the several transactions, insisting he only infiltrated Poly’s community to expose the vulnerability, saying to be “hacking for good” and in a four-component Q&A Thursday, calling the heist “1 of the most effective moments in my lifestyle.”
The reversal comes following Poly demanded in a slew of tweets since Tuesday that the hacker commence returning the resources to three cryptocurrency wallet addresses, at a single position saying the dollars stolen belonged to “tens of thousands of crypto community customers.”

Meanwhile, Jay Hao, the CEO of cryptocurrency trade OKEx, mentioned the organization is “watching the move of coins and will do [its] very best to manage the condition.”

SlowMist asserts the hacker took advantage of a vulnerability in Poly’s clever contracts to accessibility the stolen resources, but other industry experts are not so certain. Safety auditor BlockSec, for illustration, speculates the hacker could have obtained Poly’s private essential by a leak and utilised it to transact funds.
