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. Installation automatically runs a disguised Node helper that can compile and launch a detached local SSH server. It writes persistent server state outside the package directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T19:44:59.092Z - **Finished:** 2026-09-11T19:45:53.674Z - **Download time:** 260 ms - **Static scan time:** 68 ms - **AI review time:** 54253 ms - **Total time:** 54582 ms The recorded confidence comes from the underlying analysis.

It writes persistent server state outside the package directory. - **Trigger:** npm install, including a non-interactive install. - **Impact:** An install modifies user home configuration and cache paths and launches a background process without an interactive user's approval. - **Evidence paths:** package.json, lib/preinstall.js, lib/postinstall.js, BotFork Shortcut.txt - **Review source:** ai\_review - **Reviewed:** 2026-09-11T19:45:53.674Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle hook launches a disguised helper that builds and starts a background binary. - **Attack narrative:** The package uses preinstall and postinstall hooks. In automated installs, preinstall explicitly bypasses its consent prompt. Postinstall then launches a helper disguised as a text file. The helper compiles bundled Go source, writes cache and configuration files in the user home directory, and starts a detached SSH server. These install-time effects occur without a user command and exceed ordinary package setup. - **Rationale:** Automatic lifecycle execution bypasses consent in non-interactive contexts and launches a concealed helper that builds and persists a background service outside the package. This is concrete install-hook abuse. - **Files touched:** BotFork Shortcut.txt, server-src/, ~/.cache/botfork/botfork, ~/.cache/botfork/server.pid, ~/.cache/botfork/server.log, ~/.config/botfork/hostkey, ~/.config/botfork/known\_hosts - **Network endpoints:** 127.0.0.1:2222 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Install lifecycle scripts run before and after installation., The preinstall consent gate is bypassed in non-interactive installs., Postinstall automatically launches the disguised helper., The helper builds a Go binary, writes under the user home directory, and starts a detached server., The executable helper is deliberately stored as a .txt file. - **Evidence against:** No external network endpoint is hard-coded; the server defaults to loopback. ## Affected versions and remediation This report applies to botfork@0.2.37. - Avoid installing botfork@0.2.37. 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.
