North Korea's Lazarus Group laundered an additional 62,200 Ether, worth $138 million, from the February 21 Bybit hack on March 1 — leaving only 156,500 Ether untransferred, an anonymous cryptocurrency analyst noted.

About 343,000 Ether out of the 499,000 Ether stolen in the $1.4 billion Bybit hack have been moved, an EmberCN user said, who hopes the remaining funds will be cleared in the next three days.

343,000 Ether moved is equivalent to 68.7% of the stolen funds — up from 54% on February 28.

EmberCN previously noted that money laundering activities have slowed down amid the FBI's efforts to urge node operators, cryptocurrency exchanges, bridges, and other parties to block transactions related to Bybit hackers.

FBI has shared 51 Ethereum addresses operated by or linked to Bybit hackers, while blockchain analysis company Elliptic has flagged over 11,000 cryptocurrency wallet addresses that may be linked to them.

Cryptocurrency firm Chainalysis reported that hackers converted some of the stolen Ether into Bitcoin, DAI stablecoin, and other assets through decentralized exchanges, cross-chain bridges, and instant swap services without the Know Your Customer protocol.

One of those protocols includes the THORChain cross-chain asset swap protocol. The developers behind this protocol have faced heavy criticism for facilitating a significant portion of the transactions made by North Korean hackers.

One of the THORChain developers, known as "Pluto", stated that they will no longer contribute to this protocol after the vote to block transactions related to North Korean hackers was canceled.

In a note sent to Cointelegraph, THORChain founder John-Paul Thorbjornsen stated that he is no longer involved with this cross-chain protocol, also pointing out that no cryptocurrency wallet addresses approved by the FBI and the Office of Foreign Assets Control of the Treasury interacted with this protocol.

The Bybit hack worth $1.4 billion on February 21 so far is the largest exploit in the cryptocurrency industry — double the losses from the Ronin bridge hack worth $650 million on March 23, 2022.
