ABSTRACT:
A stealth threat detection manager detects stealth threats. The stealth threat detection manager monitors system activities that are vulnerable to being used by stealth threats. Dynamic link libraries are often used by stealth threats, so in some embodiments the stealth threat detection manager monitors for the loading thereof. The stealth threat detection manager detects when a system activity being monitored occurs, and after the occurrence of the activity, determines whether a specific component associated with the activity (e.g., the dynamic link library being loaded) is accessible on the computer. If the component is accessible, the stealth threat detection manager concludes that the component is non-stealthed. On the other hand, if the component is not accessible, the stealth threat detection manager concludes that the component is a stealth threat, and takes appropriate action in response.
