This rule detects instances where the Terraform CLI tool connects to suspected lookalike domains associated with supply chain compromise attempts (e.g., hashicorp-aws[.]com or hashicorp-terraform[.]io) during common initialization or application workflows. It correlates process execution with network connection logs and optionally validates the presence of a related .terraform.lock.hcl file associated with the malicious origin.
Detects the GHAPPIER four-stage malware loader, specifically targeting npm-based JavaScript files. The rule identifies malicious activity through specific artifacts including hardcoded C2 URLs (vercel.app domains), campaign markers, file paths, and eval-based execution patterns.
Detects npm package publishing events performed via GitHub Actions OIDC trusted publishing that occur without the use of a traditional npm token. This rule targets potentially unauthorized package releases triggered by automated CI/CD identities, which may indicate abuse of compromised workflows or misconfigured auto-publish settings.
Detects the obfuscated index.js payload bundled in the compromised actions-cool/issues-helper and actions-cool/maintain-one-comment commit a0c53dd42fc842d2f9276c5a1d4f9a26abe8713d, executed via 'bun run $GITHUB_ACTION_PATH/index.js'

Detects a git checkout to a specific SHA followed by a git rev-parse HEAD verification command within AI coding assistant plugin directories (e.g., claude, codex, copilot, gemini). This pattern is monitored to identify potential supply chain compromises where a working tree might be silently substituted during plugin installation or updates.
Detects anomalous network connections initiated by a node.exe process spawned by npm.exe within 2 minutes of a lifecycle script (preinstall or postinstall) execution. This behavior is indicative of malicious dependency installation where a compromised package attempts to exfiltrate data or fetch additional payloads immediately upon installation.

Detects obfuscated PHP code within the Admin Menu Editor Pro plugin, specifically targeting indicators associated with the supply chain compromise of versions 2.35 and 2.36. The rule searches for common PHP execution functions used in web shells within the context of the vulnerable plugin directory.
Detects Git commands initiated by AI coding agent processes that perform a checkout of a specific 40-character SHA hash or a FETCH_HEAD reference. This behavior is potentially indicative of a supply chain attack where an AI plugin agent is being instructed to swap code components or load specific, potentially malicious, commit versions from a remote repository.
Detects instances where AI coding agents (such as Claude Code, Copilot, etc.) execute git commands (checkout, fetch, clone) using a branch name or reference formatted as a 40-character hex string. This behavior is indicative of a 'Plugin4Shell' style bypass, where an attacker crafts a branch name that mimics a commit SHA to cause ambiguous refname errors or hijack repository operations.
This rule detects attempts to download known malicious NPM packages from the public npm registry (registry.npmjs.org) by monitoring network connection logs. It specifically looks for tarball (.tgz) downloads of packages and versions that have been identified as compromised or malicious. The rule extracts the package name and version from the download URL and compares it against a predefined list of malicious packages for high-fidelity detection.
Detects the execution of Terraform commands (init, apply, plan) that interact with the 'registry.coder.com' domain, or direct network connections to the associated infrastructure. This may indicate the use of unauthorized or compromised Infrastructure-as-Code (IaC) modules or malicious supply chain activity involving Terraform configurations.
Detects the creation of tar archives within the Coder database during a specific window associated with rogue IP activity, where the file creation was performed by a system-level process.
Detects credential harvesting behavior originating from known malicious RubyGems packages (pwnp999, exfiltestwand3, hacksvn1778554764) observed in RubyDoc.info build environments. The rule monitors process execution and file access activity involving these packages where the command line or file path includes patterns associated with credential theft (e.g., 'api_key', 'Authorization'), scoped to Ruby-related tooling such as 'ruby', 'gem', or 'bundle'.
