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 automatically executes a helper disguised as a dry-run probe. The helper builds and detaches a local server, writes state outside the package, and initiates an SSH session. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T19:25:53.749Z - **Finished:** 2026-09-11T19:27:00.106Z - **Download time:** 504 ms - **Static scan time:** 55 ms - **AI review time:** 65797 ms - **Total time:** 66357 ms The recorded confidence comes from the underlying analysis.

The helper builds and detaches a local server, writes state outside the package, and initiates an SSH session. - **Trigger:** npm install, through the postinstall lifecycle hook - **Impact:** Installation can leave a compiled background process and SSH configuration/cache state in the user's home directory without a user command. - **Evidence paths:** package.json, lib/postinstall.js, BotFork Shortcut.txt - **Review source:** ai\_review - **Reviewed:** 2026-09-11T19:27:00.106Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic detached server creation and SSH connection from an install hook - **Attack narrative:** The postinstall hook starts the hidden helper with a probe variable and describes this as a dry run. The helper does not use that variable to avoid its default path: it builds a binary, detaches it, writes persistent state under the user's home directory, and attempts SSH. This is undisclosed install-time persistence and command execution. - **Rationale:** The claimed dry-run behavior contradicts the helper's actual default control flow. Automatic creation of a detached service and home-directory state during installation is concrete install-hook abuse. - **Files touched:** BotFork Shortcut.txt, server-src/, ~/.config/botfork/hostkey, ~/.config/botfork/known\_hosts, ~/.cache/botfork/botfork, ~/.cache/botfork/server.pid, ~/.cache/botfork/server.log - **Network endpoints:** localhost:2222, 127.0.0.1:2222 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall lifecycle hook automatically., Postinstall launches the hidden helper while claiming it is a dry-run that does not contact the server., The helper ignores the probe flag for control flow and starts a full session, including SSH connection., That automatic flow builds and detaches a binary, then writes a PID file outside the package., The helper stores server state and SSH material under the user's configuration and cache directories. - **Evidence against:** No npm dependency on another botfork release was found., The default server address is loopback., No source path was found that harvests credentials or uploads local files. ## Affected versions and remediation This report applies to botfork@0.2.36. - Avoid installing botfork@0.2.36. 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.
