A later published release can replace the global package without a separate install step. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 0.1.10 - **Selected version is latest:** No - **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. A user-run salesbot command launches an agent with a package MCP server. That server sends environment values to the fixed portal and executes a command string from the portal response. The same launch checks npm and can globally install a newer release of this package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-24T01:11:43.111Z - **Finished:** 2026-09-24T01:14:14.928Z - **Download time:** 1040 ms - **Static scan time:** 164 ms - **AI review time:** 150613 ms - **Total time:** 151817 ms The recorded confidence comes from the underlying analysis.

That server sends environment values to the fixed portal and executes a command string from the portal response. The same launch checks npm and can globally install a newer release of this package. - **Trigger:** Running a salesbot bin or agent-core so the launcher starts, and the agent invoking the MCP tool that handles env\_vars. - **Impact:** The portal can receive caller-supplied environment values and choose a local command to run. A later published release can replace the global package without a separate install step. - **Evidence paths:** dist/index.js, dist/launcher.js, launcher.config.json, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-24T01:14:14.928Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher writes an mcpServers config that starts node with the portal URL and token, then spawns the agent. The MCP handler POSTs env\_vars to the portal and passes a response field to child\_process. A newer registry version is installed with a detached global npm install. - **Attack narrative:** Running a salesbot command starts the launcher. It contacts the portal named in launcher.config.json, writes a local MCP config that starts this package under node with the portal URL and tool token, and spawns the agent with that config. The MCP tool posts mcp\_id and env\_vars to the portal, then runs a child process on a string taken from the portal JSON. The launch also checks the npm registry and, when a newer version exists, starts a detached global install of this package at latest. The shipped launcher and server are obfuscated. - **Rationale:** The MCP handler sends environment values to the fixed portal and executes a command taken from that response, while the launcher can background-install a newer global release. That is remote command execution from a user-run entrypoint, with the portal host set in launcher.config.json. - **Files touched:** auth.json, vault.key, secrets.enc, memo.md - **Network endpoints:** https://prompt-injection-tool-portal.vercel.app, https://registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 86.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The MCP tool posts mcp\_id and env\_vars to the portal, then passes a field from that JSON response to child\_process., launcher.config.json fixes portalUrl to https://prompt-injection-tool-portal.vercel.app., dist/launcher.js builds an mcpServers entry that runs node with the portal URL and tool token, then writes that config and spawns the agent., On launch, dist/launcher.js reads the npm latest metadata and starts a detached global install of this package at @latest., package.json build:publish runs javascript-obfuscator, and the shipped dist/index.js and dist/launcher.js are obfuscated. - **Evidence against:** package.json has no preinstall, install, or postinstall script, so the behavior is not an npm lifecycle hook., Local vault helpers store secrets in mode 0o600 and the name-list helper does not print secret values., The Claude-style launch is reached from the salesbot bin commands, which the user invokes. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.10. - Avoid installing @funny-booth/agent-core@0.1.10. 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.
