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. Installing the package runs a concealed helper rather than merely validating it. The helper starts a detached compiled server, changes user configuration and cache state, and makes an SSH connection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T13:42:18.471Z - **Finished:** 2026-09-11T13:43:13.728Z - **Download time:** 511 ms - **Static scan time:** 23 ms - **AI review time:** 54722 ms - **Total time:** 55257 ms The recorded confidence comes from the underlying analysis.

The helper starts a detached compiled server, changes user configuration and cache state, and makes an SSH connection. - **Trigger:** npm installation runs postinstall. - **Impact:** Unconsented process creation, user-home mutations, local listener creation, and SSH activity occur during installation. - **Evidence paths:** package.json, lib/postinstall.js, BotFork Shortcut.txt - **Review source:** ai\_review - **Reviewed:** 2026-09-11T13:43:13.728Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Disguised helper execution from an install lifecycle hook. - **Attack narrative:** npm executes lib/postinstall.js, which starts the hidden BotFork Shortcut.txt file with BOTFORK\_PROBE set. That variable is never checked. The helper therefore follows its default path: builds and launches a detached server, writes a host key and cache files, then invokes SSH. Its claim that the launch is a dry run that does not connect is contradicted by the source. The misleading filename and automatic install-time side effects conceal behavior that should require an explicit user command. - **Rationale:** This is concrete concealed install-hook abuse, not a user-invoked setup flow. The lifecycle hook triggers process creation, persistent user-home changes, and SSH activity without consent. - **Files touched:** BotFork Shortcut.txt, lib/postinstall.js, ~/.config/botfork/hostkey, ~/.config/botfork/known\_hosts, ~/.cache/botfork/botfork, ~/.cache/botfork/server.pid, ~/.cache/botfork/server.log - **Network endpoints:** localhost:2222 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall hook., The hook silently launches a disguised executable helper., The helper explicitly conceals itself with a .txt name., The helper ignores BOTFORK\_PROBE and starts a detached server, writes user files, and initiates SSH during installation., The postinstall claim that it does not connect conflicts with the helper's default execution path. - **Evidence against:** The bundled Go CLI exposes only a small fixed command set., No credential harvesting or HTTP exfiltration was found in inspected source. ## Affected versions and remediation This report applies to botfork@0.2.18. - Avoid installing botfork@0.2.18. 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.
