What it detects

This rule detects execution of the Visual Studio Code command line binary with the tunnel argument, which creates a remote-access tunnel back to a VSCode account. The Stately Taurus espionage group abused this feature to obtain interactive reverse-shell access to government hosts in Southeast Asia while blending in with legitimate developer traffic. Abuse of a trusted developer tool for command and control lets the actor evade network controls and persist covertly.
