## Description

An issue was discovered in Heimdal Thor agent versions 3.4.2 and before on Windows and 2.6.9 and before on macOS, allows attackers to bypass network filtering, execute arbitrary code, and obtain sensitive information via DarkLayer Guard threat prevention module.

The product was not designed to intercept DNS requests from third-party solutions.
