Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — A package installation exposes build-host identity, environment metadata, and local account records to external endpoints. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 99.0.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-16299 identifies this version as malicious. 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 automatically collect host and account data, including /etc/passwd, then transmit it to external collectors. The package's self-described research purpose does not establish consent for this behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-21T23:58:20.919Z - **Finished:** 2026-09-21T23:59:07.250Z - **Download time:** 762 ms - **Static scan time:** 22 ms - **AI review time:** 45546 ms - **Total time:** 46331 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 automatically collect host and account data, including /etc/passwd, then transmit it to external collectors. The package's self-described research purpose does not establish consent for this behavior. - **Trigger:** npm preinstall or postinstall. - **Impact:** A package installation exposes build-host identity, environment metadata, and local account records to external endpoints. - **Evidence paths:** package.json, payload.js - **Review source:** ai\_review - **Reviewed:** 2026-09-21T23:59:07.250Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** payload.js executes shell identity commands, reads /etc/passwd, serializes the fingerprint, and sends it in HTTP requests. - **Attack narrative:** Installing the package invokes payload.js before and after installation. The script runs identity commands, reads /etc/passwd, gathers environment and npm metadata, then encodes and transmits the data to three external endpoints. This is unconsented install-time data exfiltration. - **Rationale:** Automatic lifecycle execution collects sensitive local and build-environment data and sends it to unrelated external hosts. This is concrete malicious install-time exfiltration. - **Files touched:** /etc/passwd - **Network endpoints:** http://sobaka-kusaka.ru:8000/oob/, http://sobaka-kusaka.ru:8898/c/, http://ii473egh1b4kbaw03rf7pkzik9q0er8fx.oastify.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 payload.js during both preinstall and postinstall., The payload collects the hostname, user and identity command output, system details, npm metadata, environment username, and /etc/passwd., It base64-encodes collected data for multiple external collection endpoints and sends request bodies through Node HTTP(S). ## Affected versions and remediation This report applies to @pwaplatform/module-sso-integration@99.0.0. - Avoid installing @pwaplatform/module-sso-integration@99.0.0. 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.
