Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. A global npm installation runs a bundled platform binary and persists a botmux launcher plus a PATH entry. The source limits this behavior to recognized global installations, but it still changes user shell configuration automatically. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-15T08:15:39.226Z - **Finished:** 2026-09-15T08:16:26.351Z - **Download time:** 513 ms - **Static scan time:** 113 ms - **AI review time:** 46499 ms - **Total time:** 47125 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A global npm installation runs a bundled platform binary and persists a botmux launcher plus a PATH entry. The source limits this behavior to recognized global installations, but it still changes user shell configuration automatically. - **Trigger:** Installing botmux globally through npm or a recognized global package-manager layout. - **Impact:** The package can execute a platform binary with installer environment variables and modify shell startup files. - **Evidence paths:** package.json, scripts/postinstall-bin.mjs, scripts/install-path-entry.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-15T08:16:26.351Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall binary probe and global launcher/PATH persistence. - **Rationale:** This is a same-product global launcher migration with automatic persistence and install-time binary execution. Its constrained guard and lack of observed exfiltration make it unsuitable for a block, but the lifecycle behavior warrants a warning. - **Files touched:** ~/.botmux/bin/botmux, user shell startup file ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook runs automatically on installation., For global installs, the hook executes a platform binary with the full inherited environment., The hook writes a launcher and modifies the user's shell startup files to add its directory to PATH. - **Evidence against:** The hook exits for ordinary non-global dependency installs., The executed binary is resolved from a same-version, platform-specific optional dependency., No source in this snapshot harvests credentials or sends network requests during postinstall., There is no runtime dependency on botmux itself. ## Affected versions and remediation This report applies to botmux@3.22.0. - Review the evidence and your use of botmux@3.22.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall-bin.mjs ``` ### 2. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 7. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 8. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 9. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** scripts/install-path-entry.mjs\#virtual:normalized:round1 - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```text stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 2 ``` ### 10. Medium: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 86.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook runs automatically on installation. Public source snippet (untrusted): ```json "prepublishOnly": "npm run build", "postinstall": "node scripts/postinstall-bin.mjs", "prepare": "git config core.hooksPath scripts/git-hooks 2>/dev/null || true" ``` ### 11. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 86.0% - **Path:** scripts/postinstall-bin.mjs - **Public source:** [View source]() For global installs, the hook executes a platform binary with the full inherited environment. Public source snippet (untrusted): ```javascript const probe = spawnSync(binary, ['--version'], { encoding: 'utf-8', timeout: 30_000, env: { ...process.env, BOTMUX_INSTALL_PROBE: '1' }, }); ``` ### 12. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 86.0% - **Path:** scripts/postinstall-bin.mjs - **Public source:** [View source]() The hook writes a launcher and modifies the user's shell startup files to add its directory to PATH. Public source snippet (untrusted): ```javascript const binDir = join(homedir(), '.botmux', 'bin'); const launcher = join(binDir, 'botmux'); // `exec` replaces the shell process, so signals/exit codes pass straight through // to the binary. No `node` anywhere in this launcher — that is the entire point. const content = `#!/bin/sh\nexec "${binary}" "$@"\n`; ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, prepare, prepublishOnly - **Dependencies:** 14 - **Optional dependencies:** 7 - **Peer dependencies:** 0 - **Development dependencies:** 19 - **Published dependency-graph edges:** 21 ### Published dependency entries - @larksuiteoapi/node-sdk ^1.64.0 (Dependency) - @modelcontextprotocol/sdk ^1.29.0 (Dependency) - @xterm/addon-unicode11 ^0.9.0 (Dependency) - @xterm/headless ^6.0.0 (Dependency) - croner ^10.0.1 (Dependency) - dotenv ^17.3.1 (Dependency) - markdown-it ^14.1.1 (Dependency) - proxy-agent ^6.5.0 (Dependency) - qrcode-terminal ^0.12.0 (Dependency) - react ^19.2.7 (Dependency) - react-dom ^19.2.7 (Dependency) - ws ^8.19.0 (Dependency) - yaml ^2.9.0 (Dependency) - zod ^3.23.0 (Dependency) - @napi-rs/canvas ^0.1.65 (OptionalDependency) - botmux-darwin-arm64 3.22.0 (OptionalDependency) - botmux-darwin-x64 3.22.0 (OptionalDependency) - botmux-linux-arm64 3.22.0 (OptionalDependency) - botmux-linux-arm64-musl 3.22.0 (OptionalDependency) - botmux-linux-x64 3.22.0 (OptionalDependency) - botmux-linux-x64-musl 3.22.0 (OptionalDependency) ## Package metadata - **Package:** botmux - **Ecosystem:** npm - **Version:** 3.22.0 - **License:** MIT - **Version published:** 2026-09-14T06:51:38.396Z - **Package first seen:** 2026-06-30T22:10:23.643Z - **Package last seen:** 2026-10-08T01:41:27.574Z - **Known versions:** 48 - **Latest version:** 3.36.0 - **Appeal under review:** No - **Description:** Bridge between IM platforms and AI coding CLIs — one topic, one CLI session with live streaming - **Maintainers:** deepcold - **Runtime engines:** node: \>=22 - **Artifact files:** 6 - **Artifact unpacked size:** 70,230 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
