A Bybit hack case study attributes a $1.46 billion cryptocurrency theft to North Korea’s Lazarus Group and uses it to explain modern crypto laundering workflows. The excerpt describes two intrusion paths: malicious JavaScript injected into a third-party wallet tool to manipulate smart contract behavior, and social engineering that led a SAFE Wallet developer to run a fake Docker container with persistent access. After gaining control, the attackers hijacked proxy contracts, withdrew ETH and ERC-20 tokens, and laundered funds through decentralized exchanges, wallet splitting, Bitcoin bridges, and mixers such as Wasabi Wallet. The material matters for DPRK tracking because it links technical compromise, smart-contract abuse, and laundering tradecraft to a major Lazarus cryptocurrency theft.
