Security teams at crypto exchanges Binance and Huobi have successfully frozen and recovered 121 Bitcoin (BTC) from the hackers behind the Harmony bridge exploit.

The incident occurred on June 24th, when Harmony team detected the exploit and reported $100 million in funds compromised.

According to Binance CEO Changpeng Zhao, the hackers tried to launder their funds through the Huobi exchange.

Binance detected this and then contacted and assisted Huobi to freeze and recover the digital assets deposited by the hackers. In total, the exchanges recovered 121 BTC, which is estimated to be worth around $2.5 million at the time of writing.

On-chain crypto detective ZachXBT also highlighted that prior to Binance and Huobi freezing and detecting the funds, the hackers behind the exploit were moving around 41,000 Ether (ETH), worth around $64 million, in the last weekend.

The hackers consolidated and deposited the digital assets on three different crypto exchanges, though the exchanges were not named.

In the wake of the hack, the Lazarus Group, an infamous North Korean hacking organization, was identified as a suspect behind the $100 million Harmony hack.
