Visual Studio Code Tunnel Remote File Creation

Sigma Rules

View Source
Summary
This rule detects the creation of files in the '.vscode-server' directory which is associated with Visual Studio Code's remote development feature. It specifically looks for instances where 'node.exe' is involved in this action, which may indicate unauthorized remote file creation via the VSCode tunnel mechanism. The rule identifies the presence of the 'node.exe' process from a particular path and further inspects if a file is created in the specified directory which contains relevant user history data. Such activity can be considered suspicious and may represent command and control behavior if exploited by an attacker.
