Poly Network hacker returns less than 1% of the $600M theft

These transfers have occurred across the three wallets associated with the Poly Network hacker across the Ethereum, Binance Smart Chain (BSC) and Polygon networks. Poly Network confirmed receipt of the returned funds via a tweet issued on Tuesday.

Details from Etherscan show that $2 million worth of Shiba Inu (SHIB) and $616,000 in Fei USD (FEI) tokens are being returned.

So far, we have received a total value of $4,772,297.675 assets returned by the hacker.

Data from BscScan also shows the hacker returning 23.88 Binance-peg Bitcoin (BTCB) to the Poly Network. As of the time of writing, the “coins” are worth a little over $1 million. The hacker’s BSC wallet still shows outgoing transactions for USD Coin (USDC) and Binance USD (BUSD), but these do not amount to a significant figure.

From the attacker’s Polygon wallet address, there has been a refund of $1,010,100 USD sent in three transactions — $10, $100 and $1 million, respectively.

In total, the hacker has returned $4.6 million, which is less than 1% of the over $600 million drained from Poly Network in the hack.

The hacker still holds about $500 million worth of tokens with the bulk of the sum held in Ether (ETH), including Binance-pegged ETH, and wrapped Bitcoin (WBTC) on both BSC and Ethereum chains, as well as Dai (DAI) and USDC stablecoins.

As previously reported by Cointelegraph, the Poly Network attack is the largest decentralized finance (DeFi) hack to date, taking the total value of thefts in the market segment to over $1.1 billion in 2021, almost 10 times the total losses recorded in 2020.

Indeed, since the latter half of 2020, DeFi has been contributing a greater share of crypto thefts amid a decline in centralized exchange hacking incidents.
