Threat Intel FAQ

What makes hVNC exploits dangerous for enterprise security?

hVNC exploits allow attackers to interact with a system while remaining hidden from the legitimate user. This facilitates long-term unauthorized access, data theft, and lateral movement without triggering visible security warnings.

How can I protect my organization against zero-day threats?

Protection against zero-day threats relies on a proactive defense-in-depth strategy. This includes regular vulnerability scanning, reducing the internet-facing attack surface, enforcing zero-trust architecture, and implementing behavioral-based EDR monitoring to detect anomalies in system calls.
