Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Browser session credentials and application data may be disclosed to the external operator. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 1.0.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-17217 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. The package entrypoint collects browser authentication and storage data and posts it to an external endpoint. This is active data exfiltration when the entrypoint runs in a browser-like environment. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-27T03:19:38.096Z - **Finished:** 2026-09-27T03:20:08.187Z - **Download time:** 512 ms - **Static scan time:** 7 ms - **AI review time:** 29572 ms - **Total time:** 30091 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:** The package entrypoint collects browser authentication and storage data and posts it to an external endpoint. This is active data exfiltration when the entrypoint runs in a browser-like environment. - **Trigger:** Loading the package entrypoint where document storage is available. - **Impact:** Browser session credentials and application data may be disclosed to the external operator. - **Evidence paths:** package.json, app.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T03:20:08.187Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The code reads cookies, local storage, and session storage, serializes them, and sends them with fetch POST requests. - **Attack narrative:** When the declared entrypoint loads in a browser context, it checks for cookies and populated browser storage. It posts each available value to an external challenge-domain endpoint using fetch. Cookies can contain session credentials, while local and session storage can contain tokens and application data. - **Rationale:** The active entrypoint implements unsolicited browser credential and data collection followed by transmission to an unrelated external endpoint. This is concrete credential and data exfiltration behavior. - **Files touched:** app.js - **Network endpoints:** https://c-b34596407b6d47d6.dgactf-challs.site/addPost ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest sets app.js as the package entrypoint., The entrypoint sends browser cookies to an external challenge-domain endpoint when cookies exist., The entrypoint also sends browser local storage and session storage content to that endpoint., The helper uses an HTTP POST request to transmit supplied data. ## Affected versions and remediation This report applies to my-skibidi@1.0.3. - Avoid installing my-skibidi@1.0.3. 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.
