Utility to create AdGuard DNR rulesets for mv3 extensions

AI Security Review

scanned 23d ago · by lpm-firewall-ai

No install-time attack surface is present. This package loads AdGuard declarative net-request rulesets and patches an extension manifest only when a developer runs the published CLI or library APIs. Scanner malware fingerprints on the bundled CLI and adblock scriptlet assets are product-aligned, not a hidden payload.

Static reason

No blocking static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

User runs the dnr-rulesets command or calls AssetsLoader/ManifestPatcher after install.

Impact

No confirmed malicious impact; project files change only when the user asks to load rulesets or patch a manifest.

Mechanism

Copy prebuilt rulesets and optionally download AdGuard filter lists

AI rationale

Source inspection shows an AdGuard MV3 ruleset utility with no install hooks and with network and file writes gated on explicit CLI or API use. High scanner hits on dist/cli.cjs are a noisy match against a large bundled product CLI, not concrete malware.

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json ships a user-invoked dnr-rulesets CLI and library entry with only build, test, and lint scripts.
dist/cli.cjs is a large bundled Node CLI requiring commander and axios, which is why malware-fingerprint and new-file scanners flagged it.
