An explicit CLI command may download AdGuard filter assets and write ruleset output to a user-supplied destination. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 98.0% - **Started:** 2026-08-17T04:13:06.791Z - **Finished:** 2026-08-17T04:13:56.861Z - **Download time:** 3796 ms - **Static scan time:** 13304 ms - **AI review time:** 32969 ms - **Total time:** 50070 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. An explicit CLI command may download AdGuard filter assets and write ruleset output to a user-supplied destination. - **Trigger:** User runs the dnr-rulesets CLI load or watch command. - **Impact:** Intended creation or update of ruleset files in the selected output path. - **Evidence paths:** package.json, dist/cli.cjs, dist/lib/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T04:13:56.861Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Download and transform MV3 DNR filter rulesets. - **Rationale:** Direct inspection found no install-time execution, credential harvesting, shell execution, persistence, or covert exfiltration. The scanner similarity signal is unsupported by the reviewed source behavior. - **Files touched:** package.json, dist/cli.cjs, dist/lib/index.js - **Network endpoints:** https://filters.adtidy.org/extension/%browser%/filters ### Review decision - **Verdict:** Clean - **Confidence:** 98.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** Manifest exposes a library and user-invoked CLI; no lifecycle hooks are declared., CLI registers explicit ruleset load/manifest/watch commands., Network retrieval is limited to AdGuard filter assets and writes to CLI-supplied destinations., CLI execution is guarded against import-time invocation. - **Evidence against:** The explicit load/watch options can download remote filter content., The package ships a WASM regex dependency, but no native loader or execution chain was found. ## Public findings ### 1.
