Hackers Weaponize OpenAI API in NIK C2 Framework for Credential Theft and Remote System Control
NIK C2 malware framework weaponizes OpenAI API for credential theft and remote system control.
A new Go-based malware framework named NIK C2 leverages the OpenAI API for sophisticated cyberattacks, including credential theft, remote system control, and even ransomware-like screen locking. The malware can exfiltrate sensitive data like browser passwords, Wi-Fi credentials, and cryptocurrency wallet information, and uses OpenAI's models for data analysis, potentially billing victims directly for API usage.

The lesson from this incident
Full lessonThe NIK C2 framework represents a dangerous evolution in malware design, weaponizing legitimate AI APIs to conduct credential theft, remote system control, and ransomware-like attacks. Attackers exploit the trust placed in well-known platforms like OpenAI to blend malicious traffic with legitimate API calls, making detection significantly harder. Victims may not only lose sensitive data — including browser passwords, Wi-Fi credentials, and cryptocurrency wallet information — but could also be billed for the attacker's AI API usage. This incident underscores how emerging AI tools can be repurposed as attack infrastructure, and that users and organizations must scrutinize API key exposure and monitor outbound connections to AI services. Without robust endpoint protection and user awareness, even sophisticated C2 frameworks can operate undetected for extended periods.
What helps against this
How we list vendors
- Secrets management
API keys, tokens and passwords stop leaking from code, chat and configuration files.
- Endpoint detection and response (EDR and XDR)
Malware and hands-on-keyboard attackers on laptops and servers get spotted and stopped.
- Data loss prevention (DLP)
Sensitive data cannot quietly leave by email, upload, USB stick or AI tool.
