The North Korean state-backed hacking crew, otherwise known as the Lazarus Group, has been attributed to yet another financially motivated campaign that leverages a trojanized decentralized finance (DeFi) wallet app to distribute a fully-featured backdoor onto compromised Windows systems.
The app, which is equipped with functionalities to save and manage a cryptocurrency wallet, is also designed to trigger the launch of the implant that can take control of the infected host. Russian cybersecurity firm Kaspersky said it first encountered the rogue application in mid-December 2021.
The infection scheme initiated by the app also results in the deployment of the installer for a legitimate application, which gets overwritten with a trojanized version in an effort to cover its tracks. That said, the initial access avenue is unclear, although it’s suspected to be a case of social engineering.
The spawned malware, which masquerades as Google’s Chrome web browser, subsequently launches a wallet app built for the DeFiChain, while also establishing connections to a remote attacker-controlled domain and awaiting further instructions from the server.
