Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Remote code from the endpoint executes with the package user's privileges. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 1.0.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-17649 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 exported command downloads and executes a remote shell script. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-08T00:52:10.450Z - **Finished:** 2026-10-08T00:52:22.927Z - **Download time:** 506 ms - **Static scan time:** 7 ms - **AI review time:** 11964 ms - **Total time:** 12477 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 exported command downloads and executes a remote shell script. - **Trigger:** A caller invokes the exported command. - **Impact:** Remote code from the endpoint executes with the package user's privileges. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T00:52:22.927Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command runs Bash with curl piped directly into sh. - **Attack narrative:** Invoking the exported command starts a Bash process that fetches a script from reverse-shell.sh and immediately executes it through sh. The source provides no integrity check or other restriction on the downloaded content. - **Rationale:** The main entrypoint exposes an explicit command that downloads and executes remote code, establishing a concrete remote code execution capability. The package has no install lifecycle hook, but that does not mitigate the attack when the exported command is invoked. - **Network endpoints:** https://reverse-shell.sh/10.0.75.246:443 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Calling the exported command launches Bash, downloads a script from reverse-shell.sh, and pipes it to the shell for execution., The package exposes index.js as its main entrypoint and declares no install lifecycle script. ## Affected versions and remediation This report applies to internallib\_v788@1.0.1. - Avoid installing internallib\_v788@1.0.1. 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.
