Cryptocurrency is everywhere now. Billion-dollar companies are built on it, entire economies run on Bitcoin, and cybercriminals love using it to finance their operations or hide stolen money. Cryptocurrencies promise anonymity, yet blockchain transactions are fully public, and make it tricky to hide funds. In February 2025, the Bybit breach exposed two advanced attack vectors. First, a third-party wallet tool was compromised through malicious JavaScript injected into its logic, allowing attackers to manipulate smart contract behavior. Second, a SAFE Wallet developer was tricked through social engineering into running a fake Docker container, giving attackers persistent access to his machine. With control established, they hijacked proxy contracts and executed stealth withdrawals of ETH and ERC-20 tokens. The stolen assets were laundered through decentralized exchanges, split across multiple wallets, bridged to Bitcoin, and passed through mixers like Wasabi Wallet. So how do attackers manage to launder crypto, and how can we stop them? Using the 1.46 billion dollar Bybit hack by North Korea’s Lazarus Group as a case study, this talk breaks down each laundering step and explains how to automate tracking and accelerate investigations using AI.
