The quick laundering of over $400 million from Bybit’s hack suggests North Korea may have expanded its operations, analysts say. Over $400 million from Bybit‘s $1.46 billion incident was laundered in just days, with analysts at blockchain forensic firm TRM Labs now raising serious concerns that North Korea may have expanded its laundering operations. In a Feb. 27 blog post, the analysts pointed out that Bybit’s attackers moved nearly half a billion in less than a week, using intermediary wallets, crypto swaps, decentralized exchanges, and cross-chain bridges to hide the trail. “This rapid laundering suggests that North Korea has either expanded its money laundering infrastructure or that underground financial networks, particularly in China, have enhanced their capacity to absorb and process illicit funds.” TRM Labs You might also like: ‘Blind signing is an issue, but not the prime suspect’ expert says on Bybit $1.4b saga The analysts note that North Korean hackers typically use crypto mixers to hide stolen funds before cashing out.

The attackers reportedly compromised a Safe{Wallet} developer’s device, tricking Bybit’s Safe wallet owner into signing a malicious transaction.
