Detects the execution of processes related to 'SKILL.md', 'npx', 'mcp-server', or 'invoke_skill' followed closely by read or copy actions on sensitive file locations (SSH keys, AWS credentials, environment files, or AppData). The rule further correlates this activity with subsequent outbound network connections from the same device.

Detects a code editor process (VS Code, VS Code Insiders, code-server) opening or reading the .git/config or .git/HEAD file, which may indicate a malicious editor extension harvesting private repository and CI/CD configuration data, as seen in the Open VSX "evil twin" extension campaign.

Detects a process accessing .git/config or .git/HEAD files followed by a network connection or HTTP request from the same agent within a short time window, consistent with the Open VSX 'evil twin' extension campaign harvesting private repository and CI metadata and exfiltrating it to attacker-controlled infrastructure.

Detects VS Code / Node.js processes associated with editor extensions making outbound HTTP requests that contain CI/CD environment variable names (e.g. GITHUB_REPOSITORY, CI_PROJECT_PATH, GITLAB_CI, CIRCLECI, BUILDKITE, CODESPACES, GITPOD), consistent with the Open VSX 'evil twin' extension campaign that harvested private repository and CI/CD data from developer environments.

205
Detects a settings.json (editor settings/telemetry opt-out) file read followed within a 30-second window by network transmission from the same host, a pattern consistent with the Open VSX 'evil twin' extension campaign in which extensions read local developer configuration/telemetry preference files and then exfiltrate the harvested data over the network.

Detects the execution of 'cloudflared', a tool used to establish secure tunnels from a local network to Cloudflare's edge, by monitoring for common command-line arguments such as 'service install', 'tunnel run', or '--url'. This behavior could indicate an attempt by an attacker to create a persistent or ad-hoc reverse proxy for remote access.

Detects installation of malicious "evil twin" Open VSX extensions impersonating AMD, Azure, or Salesforce that carry the tell-tale version 0.0.1 or 0.0.2, identified via file creation/write events in VS Code / Open VSX extension directories.

Detects a code editor process (VS Code, Cursor, Windsurf, VSCodium) reading the MachineGuid registry value followed within 3-8 seconds by an outbound network connection to a non-private IP from the same process on the same host, consistent with Open VSX evil-twin extensions harvesting developer machine identifiers and exfiltrating fingerprinting data.

Detects a shell process (sh, bash, cmd.exe, powershell.exe) spawned by a web application server process (java, node, python) that establishes an outbound connection to a non-private IP address, excluding known CI/CD and health-check command-line patterns — consistent with a reverse shell delivered via web application exploitation.
