hardhat-set
This document describes the management of vulnerabilities for the project and all modules within the organization.
This report shows the evidence for hardhat-set@2.21.0, the only known version.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe source establishes an import-time, obfuscated telemetry and execution payload unrelated to package functionality. No lifecycle hook is needed for the payload to run when consumers load the module.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Runtime import of index.js
Impact
Host data exfiltration and potential arbitrary command execution.
Mechanism
Obfuscated host profiling, outbound POST, and process execution
Attack narrative
index.js synchronously requires lib/config.js despite never using its export. That 4 MB top-level obfuscated file imports OS, filesystem, process-execution, HTTP, and crypto modules; constructs a host/OS/username payload; POSTs it through axios; and contains execSync/spawn plus filesystem mutation logic. This is unrelated to the declared logging middleware and executes on import.
AI rationale
The source establishes an import-time, obfuscated telemetry and execution payload unrelated to package functionality. No lifecycle hook is needed for the payload to run when consumers load the module.
Evidence
package.jsonindex.jslib/config.js
Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./lib/config at module load.
- lib/config.js is 4 MB of top-level obfuscated code with no module export.
- lib/config.js loads os, fs, child_process, axios, and crypto.
- It collects host, OS, and username then POSTs them with a validation header.
- It contains execSync/spawn and filesystem deletion/write paths.
- Manifest has no lifecycle hook; activation is package import.
Evidence against
- No install/preinstall/postinstall scripts.
- No unobfuscated endpoint is recoverable statically.

Affected versions and remediation
This report applies to hardhat-set@2.21.0.
The versions list below shows the verdict for each recorded version.
- Avoid installing hardhat-set@2.21.0. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
