WaterPlum, a North Korean-associated attack group, has been using a new malware called OtterCandy in their ClickFake Interview campaign. OtterCandy, implemented in Node.js, combines features of RATatouille and OtterCookie. It targets Windows, macOS, and Linux systems, stealing browser credentials, cryptocurrency wallets, and confidential files. The malware communicates with C2 servers via Socket.IO and has persistence mechanisms. An August 2025 update (v2) enhanced user identification, expanded theft targets, and added trace deletion capabilities. OtterCandy's evolution and its use in ongoing campaigns highlight the need for continued vigilance against WaterPlum's activities.
North Korean cybercrime activities heavily rely on Russian IP ranges in Khasan and Khabarovsk, utilizing extensive anonymization networks. The Void Dokkaebi group, linked to North Korea, employs fictitious companies like BlockNovas to target IT professionals through fraudulent job interviews, aiming to steal cryptocurrency and potentially engage in espionage. Their tactics involve using VPNs, proxies, and RDP connections to obscure their origins. Instruction videos suggest the involvement of less-skilled foreign conspirators. The primary focus remains cryptocurrency theft, but there's potential for expanded espionage activities and possible cooperation between North Korean and Russian entities.
