Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — A package author-controlled identity can remotely access the affected Windows account; the device may also join an external Tailscale network. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Persistence - **Selected version:** 1.3.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package contains an explicit remote-access provisioning script that authorizes a bundled third-party SSH key and default Tailscale enrollment credential. Although it is not install-time, this is concrete persistence and unauthorized remote-access functionality. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-07-19T00:56:45.775Z - **Finished:** 2026-07-19T00:58:24.681Z - **Download time:** 260 ms - **Static scan time:** 2 ms - **AI review time:** 98643 ms - **Total time:** 98906 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:** An administrator-executed PowerShell helper provisions persistent remote SSH access for an embedded third-party key. It also opens SSH to the network and can enroll the machine into a Tailscale tailnet using a bundled auth key. - **Trigger:** User explicitly runs \`tailcale/instalar\_ssh\_servidor.ps1\` as Administrator. - **Impact:** A package author-controlled identity can remotely access the affected Windows account; the device may also join an external Tailscale network. - **Evidence paths:** package.json, tailcale/instalar\_ssh\_servidor.ps1, ware/cdp\_recorder.py, ware/iniciar\_captura.py - **Review source:** ai\_review - **Reviewed:** 2026-07-19T00:58:24.681Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Installs an embedded SSH authorization key, enables OpenSSH/firewall access, and enrolls Tailscale with a hard-coded key. - **Attack narrative:** If a victim follows the packaged administrator PowerShell helper, it enables OpenSSH, opens firewall port 22, and writes the embedded \`edwin@EDWIN\` public key to the victim account's \`authorized\_keys\`. The script additionally offers its bundled Tailscale auth key as the recommended option and runs \`tailscale up\`, potentially joining the host to the key owner's tailnet. This creates persistent, author-controlled remote-access paths despite having no npm install hook. - **Rationale:** The package contains an explicit remote-access provisioning script that authorizes a bundled third-party SSH key and default Tailscale enrollment credential. Although it is not install-time, this is concrete persistence and unauthorized remote-access functionality. - **Files touched:** tailcale/instalar\_ssh\_servidor.ps1, $env:SystemDrive\\Users\\$username\\.ssh\\id\_ed25519, $env:SystemDrive\\Users\\$username\\.ssh\\authorized\_keys, $env:ProgramData\\ssh\\sshd\_config - **Network endpoints:** https://login.tailscale.com/admin/settings/authkeys, https://tailscale.com/download/windows ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`tailcale/instalar\_ssh\_servidor.ps1\` embeds a private SSH key and writes it into the current user's \`.ssh\` directory., The same script installs its public key as \`.ssh/authorized\_keys\`, granting \`edwin@EDWIN\` SSH access., It enables and starts \`sshd\`, opens inbound TCP/22, enables public-key auth, and restarts SSH., It embeds a default Tailscale auth key and recommends using it, then runs \`tailscale up --auth-key\`., No npm lifecycle hooks exist; the remote-access changes require explicit PowerShell execution. - **Evidence against:** \`package.json\` has no \`scripts\`, \`bin\`, or executable JavaScript entrypoint; its main is \`steps.txt\`., The web-capture Python tools are user-launched and write local session artifacts; no package-owned exfiltration endpoint was found. ## Affected versions and remediation This report applies to edwin8600@1.3.4. - Avoid installing edwin8600@1.3.4. 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.
