Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Install lifecycle hooks execute a host-fingerprinting callback without user action. The callback transmits collected installation-context data to Telegram and uses DNS as a backup channel. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-22T00:01:56.771Z - **Finished:** 2026-09-22T00:02:33.382Z - **Download time:** 505 ms - **Static scan time:** 33 ms - **AI review time:** 36072 ms - **Total time:** 36611 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Install lifecycle hooks execute a host-fingerprinting callback without user action. The callback transmits collected installation-context data to Telegram and uses DNS as a backup channel. - **Trigger:** npm installation invokes the preinstall or postinstall lifecycle hook. - **Impact:** An installer’s host and deployment context is disclosed to an unrelated operator during package installation. - **Evidence paths:** package.json, callback.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T00:02:33.382Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** callback.js gathers system, CI, cloud, network, environment-name, and file-presence metadata, posts it to a hard-coded Telegram bot, and issues an encoded DNS lookup. - **Attack narrative:** Installing the package automatically launches callback.js before and after installation. It fingerprints the machine and deployment environment, checks for sensitive configuration filenames, then silently posts a formatted report to a Telegram bot. If HTTPS is blocked, it sends selected host, user, and CI data through a DNS query. The declared research purpose does not establish consent for this automatic external reporting. - **Rationale:** Automatic install-time host reconnaissance and covert transmission to hard-coded external endpoints are concrete malicious behavior. Error suppression and a DNS fallback reinforce the intent to collect installation telemetry without consent. - **Files touched:** package.json, callback.js - **Network endpoints:** api.telegram.org, dc-callback.example.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package automatically runs callback.js during both preinstall and postinstall, suppressing errors., The callback fingerprints the installing host, user, working and home directories, CI/cloud context, network addresses, sensitive environment-variable names, and presence of credential-related files., It sends the collected report to a hard-coded Telegram bot endpoint., It also encodes host, user, and CI data into a DNS query as a fallback exfiltration path. - **Evidence against:** The code collects environment-variable names and file presence rather than reading their contents., The main entrypoint only exports metadata and logs messages. ## Affected versions and remediation This report applies to byted-commerce-materials@1.0.0. - Avoid installing byted-commerce-materials@1.0.0. 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. ## Public findings ### 1.
