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 despite a claimed dry run. It builds and starts a detached local TCP server, writes host-key, log, and process files, then attempts an SSH connection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T16:01:01.050Z - **Finished:** 2026-09-11T16:01:56.130Z - **Download time:** 252 ms - **Static scan time:** 20 ms - **AI review time:** 54807 ms - **Total time:** 55080 ms The recorded confidence comes from the underlying analysis.

It builds and starts a detached local TCP server, writes host-key, log, and process files, then attempts an SSH connection. - **Trigger:** npm installation - **Impact:** Installation can create a background service and modify user configuration and cache without an explicit command. - **Evidence paths:** package.json, lib/postinstall.js, BotFork Shortcut.txt, server-src/internal/server/server.go - **Review source:** ai\_review - **Reviewed:** 2026-09-11T16:01:56.130Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall launches an unchecked helper that starts a detached server - **Attack narrative:** npm invokes lib/postinstall.js, which launches the misleadingly named helper with BOTFORK\_PROBE set. The helper never reads that flag, so it follows its normal start path: it builds a binary, writes state under the user configuration and cache directories, starts it detached, and opens a local TCP service. This is unconsented install-time execution and persistence-like state creation, not validation. - **Rationale:** The postinstall dry-run claim is contradicted by the helper’s unchecked default execution path. The package automatically launches a detached listener and alters user state during installation. - **Files touched:** BotFork Shortcut.txt, ~/.config/botfork/hostkey, ~/.cache/botfork/botfork, ~/.cache/botfork/server.pid, ~/.cache/botfork/server.log - **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:** Installation runs a postinstall script that launches the helper with ignored standard streams., The helper does not check the dry-run environment flag and takes its default path, which starts a session., That path launches a detached background process and records its process ID in the user cache., The bundled server opens a TCP listener. - **Evidence against:** No credential harvesting or external exfiltration endpoint was found., The default listener address is loopback. ## Affected versions and remediation This report applies to botfork@0.2.21. - Avoid installing botfork@0.2.21. 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.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** BotFork Shortcut.txt - **Public source:** [View source]() The helper does not check the dry-run environment flag and takes its default path, which starts a session.
