The VVS Discord Stealer is a Python-based malware designed to exfiltrate sensitive Discord user data including credentials and tokens. It uses Pyarmor with BCC mode and AES-128-CTR encryption to heavily obfuscate its code, evading detection by static and dynamic analysis tools. The malware decrypts encrypted Discord tokens, queries Discord APIs for user information, injects malicious JavaScript into the Discord client to intercept active sessions, and extracts data from multiple web browsers. It achieves persistence by configuring itself to run at system startup and deceives victims by displaying a fake error message. While no known exploits or CVEs are reported, its capabilities pose a medium severity threat. The stealer primarily targets Windows environments where Discord and browsers are installed and relies on user interaction, likely via social engineering. European organizations with significant Discord usage, especially in technology, gaming, media, and education sectors, face risks of credential theft, unauthorized access, data leakage, and operational disruption. Detection requires behavioral and heuristic analysis due to strong obfuscation techniques.
