Utility to create AdGuard DNR rulesets for mv3 extensions

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

No confirmed malicious attack surface was established. The explicit CLI load command downloads AdGuard filter assets to a user-supplied destination.

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

Trigger

A user runs the dnr-rulesets CLI load command.

Impact

Writes requested ruleset assets; no unconsented install-time action was found.

Mechanism

Downloads and converts browser declarative network-request filter rules.

AI rationale

Source inspection found a normal AdGuard ruleset builder and explicit CLI downloader, with no lifecycle hooks or concrete malicious behavior. Scanner similarity and WASM signals are not supported as an attack chain by the source.

Evidence for AI clean decision

The package exposes a user-invoked CLI that can download filter assets.
The CLI fetches only the package-aligned filters.adtidy.org endpoint and writes the requested output files.

Evidence against

package.json contains no preinstall, install, or postinstall hook.
No child-process execution, credential harvesting, AI-agent configuration access, or exfiltration code was found.
The shipped WASM is an RE2 regular-expression engine, not a staged payload.
