North Korean threat actors have escalated their sophisticated cyber operations against cryptocurrency startups, deploying an evolved malware campaign that leverages fraudulent Zoom meeting invitations to infiltrate target organizations. According to Sentinel One’s comprehensive analysis released on July 2, 2025, the attack chain incorporates AppleScript for native macOS environment manipulation, C++ for core functionality, and Nim-compiled binaries for enhanced evasion capabilities. Moonlock analysts identified significant technical evolution in this campaign, noting that attackers have dramatically increased the complexity of their malware through the integration of multiple programming languages. Cyber Security News is a Dedicated News Platform For Cyber News, Cyber Attack News, Hacking News & Vulnerability Analysis. The most significant technical advancement in this campaign involves the strategic implementation of Nim, a relatively obscure programming language that provides substantial advantages for malicious actors. The language’s syntax and behavior patterns differ significantly from commonly analyzed malware languages, creating blind spots in automated security analysis tools. The malicious code specifically targets browser-stored credentials from Chrome, Brave, Edge, Firefox, and Arc browsers, focusing on saved passwords and session cookies associated with cryptocurrency exchanges and digital wallets. The malware further compromises macOS Keychain databases to extract stored authentication credentials, while simultaneously harvesting Telegram user data including encrypted message databases and potentially two-factor authentication codes. This comprehensive data collection strategy enables threat actors to gain complete access to victims’ cryptocurrency assets and associated financial accounts. This strategic shift represents a deliberate attempt to evade detection systems and confuse cybersecurity researchers who may lack familiarity with newer, niche programming languages. Threat actors establish contact with potential targets, typically professionals in the crypto industry seeking employment, and arrange fake interviews conducted via Zoom.
