The package provides an explicitly invoked CLI/library for building, copying, and optionally downloading browser DNR filter assets. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 99.0% - **Started:** 2026-08-16T23:14:19.936Z - **Finished:** 2026-08-16T23:15:28.773Z - **Download time:** 3030 ms - **Static scan time:** 11848 ms - **AI review time:** 53958 ms - **Total time:** 68837 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The package provides an explicitly invoked CLI/library for building, copying, and optionally downloading browser DNR filter assets. - **Trigger:** User directly runs the dnr-rulesets CLI or calls its asset-loading API with latestFilters enabled. - **Impact:** Expected developer asset generation only; no install-time execution, credential collection, or unconsented persistence was found. - **Evidence paths:** package.json, dist/cli.cjs, dist/lib/index.js, dist/utils/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T23:15:28.773Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Downloads AdGuard filter metadata/text to a caller-selected destination or copies bundled rulesets. - **Rationale:** Static source inspection shows an opt-in ruleset CLI, not malware. The scanner similarity signal is unsupported by concrete malicious behavior in the inspected package. - **Network endpoints:** https://filters.adtidy.org/extension/%browser% ### Review decision - **Verdict:** Clean - **Confidence:** 99.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** CLI can download filter assets from a fixed AdGuard endpoint when explicitly invoked with latest-filter options. - **Evidence against:** package.json has no preinstall, install, postinstall, or prepare hook., The network request is a documented filter-metadata download and writes only to the caller-supplied destination., CLI execution is guarded to direct invocation; importing does not run its main routine., No credential/environment harvesting, child-process execution, or shell/network exfiltration primitive was found. ## Public findings ### 1.
