The malware operated as what Aikido described as “essentially a browser-based interceptor that hijacked both network traffic and application APIs.” The technical implementation demonstrated understanding of web3 applications, with complex logic designed to identify and replace cryptocurrency addresses across multiple blockchain networks, recognizing address formats for Ethereum, Bitcoin, Solana, Tron, Litecoin, and Bitcoin Cash.
