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 installation automatically creates a botmux launcher and appends a PATH entry to a user shell startup file. This is persistent user-environment mutation, but it is limited to the package's own command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-12T21:10:00.281Z - **Finished:** 2026-09-12T21:10:47.320Z - **Download time:** 255 ms - **Static scan time:** 127 ms - **AI review time:** 46656 ms - **Total time:** 47039 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 installation automatically creates a botmux launcher and appends a PATH entry to a user shell startup file. This is persistent user-environment mutation, but it is limited to the package's own command. - **Trigger:** Installing botmux globally through a package manager that runs postinstall. - **Impact:** The package can make its own executable persistently available in future shells and invokes its platform binary during installation. - **Evidence paths:** package.json, scripts/postinstall-bin.mjs, scripts/install-path-entry.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T21:10:47.320Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global launcher installation and shell PATH modification. - **Rationale:** The package has an automatic install hook that persists a launcher and edits shell configuration, which warrants a warning. Its actions are narrowly tied to its own global CLI and no concrete malicious behavior is present in the inspected source. - **Files touched:** ~/.botmux/bin/botmux, ~/.zshenv, ~/.bashrc, ~/.bash\_profile, ~/.bash\_login, ~/.profile, ~/.config/fish/conf.d/botmux.fish ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package automatically runs a postinstall script., For global installs, the script writes a launcher and modifies a shell startup file to add it to PATH., The postinstall script executes the selected platform binary with --version before replacing the launcher. - **Evidence against:** The lifecycle script exits for ordinary local and transitive installs., The launcher targets a same-vendor, exact-version optional platform package rather than a self-dependency., No credential collection, network request, remote download execution, or AI-agent configuration mutation appears in the published source. ## Affected versions and remediation This report applies to botmux@3.21.0. - Review the evidence and your use of botmux@3.21.0 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:** 88.0% - **Path:** package.json - **Public source:** [View source]() The package automatically runs a postinstall script. 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:** 88.0% - **Path:** scripts/postinstall-bin.mjs - **Public source:** [View source]() For global installs, the script writes a launcher and modifies a shell startup file to add it 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`; ``` ### 12. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 88.0% - **Path:** scripts/install-path-entry.mjs - **Public source:** [View source]() For global installs, the script writes a launcher and modifies a shell startup file to add it to PATH. Public source snippet (untrusted): ```javascript for (const { file, line } of targets) { if (fileAlreadyHasEntry(file, installDir)) { skipped.push(file); continue; } try { mkdirSync(dirname(file), { recursive: true }); if (existsSync(file)) { // Keep the user's file intact; only append, and only with a leading // newline so we never glue onto an unterminated last line. const prev = readFileSync(file, 'utf8'); appendFileSync(file, `${prev.endsWith('\n') || prev === '' ? '' : '\n'}${line}\n`); } else { writeFileSync(file, `${line}\n`); } written.push(file); ``` ## 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 3.21.0 (OptionalDependency) - botmux-darwin-x64 3.21.0 (OptionalDependency) - botmux-linux-arm64 3.21.0 (OptionalDependency) - botmux-linux-arm64-musl 3.21.0 (OptionalDependency) - botmux-linux-x64 3.21.0 (OptionalDependency) - botmux-linux-x64-musl 3.21.0 (OptionalDependency) ## Package metadata - **Package:** botmux - **Ecosystem:** npm - **Version:** 3.21.0 - **License:** MIT - **Version published:** 2026-09-09T15:46:42.032Z - **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:** 69,341 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
