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. Running a salesbot command contacts the configured portal, obtains MCP package data, and launches portal-selected packages through npx. It injects the portal token and local secret vault values into those packages; a portal response can also supply a command for execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-13T08:48:56.425Z - **Finished:** 2026-09-13T08:49:47.966Z - **Download time:** 773 ms - **Static scan time:** 149 ms - **AI review time:** 50618 ms - **Total time:** 51541 ms The recorded confidence comes from the underlying analysis.

It injects the portal token and local secret vault values into those packages; a portal response can also supply a command for execution. - **Trigger:** The user runs any salesbot bin command or starts the MCP server and invokes its remote-backed tool. - **Impact:** A portal-controlled package or command can execute locally with supplied credentials and access the user's environment. - **Evidence paths:** dist/bin/salesbot7.js, dist/launcher.js, dist/index.js, launcher.config.json - **Review source:** ai\_review - **Reviewed:** 2026-09-13T08:49:47.966Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote package loading, token and secret forwarding, and portal-directed command execution. - **Attack narrative:** A user launches a salesbot binary, which calls the obfuscated launcher. The launcher authenticates to the configured portal, fetches MCP definitions, and writes a Claude MCP configuration that runs each returned package through npx. It provides those packages the portal token and values from the local secret vault. Separately, the MCP server fetches a portal-provided command and executes it. These remote-controlled execution paths are concealed by obfuscation and are not limited to a fixed, reviewed dependency set. - **Rationale:** The package creates concrete remote code execution and credential exposure paths when its user-facing commands run. Obfuscation and silent global self-updating further remove meaningful user control. - **Files touched:** dist/bin/salesbot7.js, dist/launcher.js, dist/index.js, launcher.config.json, ~/.\/secrets.enc, ~/.\/vault.key - **Network endpoints:** https://app.ai-agentos.jp ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The published runtime files are deliberately obfuscated, concealing security-sensitive behavior., Each salesbot command invokes the launcher, which fetches portal-selected MCP packages and configures them to run through npx., The launcher passes its portal token and locally stored secrets into those remotely selected packages., An MCP tool accepts a command returned by the portal and executes it with child\_process., The launcher checks for updates and silently starts a detached global npm installation. - **Evidence against:** There is no npm install lifecycle hook; prepublishOnly runs only when publishing., The configured portal host is explicit in launcher.config.json. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.14. - Avoid installing @funny-booth/agent-core@0.1.14. 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.
