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 triggers a postinstall script that installs a botmux launcher and modifies shell startup configuration. It also launches a platform-specific optional dependency to probe it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-08-31T09:07:04.756Z - **Finished:** 2026-08-31T09:07:59.179Z - **Download time:** 504 ms - **Static scan time:** 91 ms - **AI review time:** 53828 ms - **Total time:** 54423 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 triggers a postinstall script that installs a botmux launcher and modifies shell startup configuration. It also launches a platform-specific optional dependency to probe it. - **Trigger:** npm i -g botmux - **Impact:** A global install changes future shell PATH behavior and executes a bundled platform binary; the binary artifact is not present in this snapshot. - **Evidence paths:** package.json, scripts/postinstall-bin.mjs, scripts/install-path-entry.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T09:07:59.179Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global launcher installation, shell PATH persistence, and binary probing - **Rationale:** This is a same-vendor global CLI migration rather than a confirmed credential theft or remote payload chain. Its automatic shell-profile mutation and execution of an uninspected optional binary leave a real lifecycle risk that warrants a warning. - **Files touched:** ~/.botmux/bin/botmux, ~/.zshenv, ~/.bashrc, ~/.bash\_profile, ~/.bash\_login, ~/.profile, ~/.config/fish/conf.d/botmux.fish ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package runs a postinstall script automatically., On global installs, the script writes a launcher under the user's home directory., The postinstall helper appends a PATH entry to shell startup files., The postinstall script executes the selected platform binary with --version. - **Evidence against:** The postinstall exits unless npm\_config\_global is exactly true., It resolves only a same-vendor platform subpackage and does not make network requests., The launcher content is a fixed exec wrapper, and the PATH value is shell-quoted. ## Affected versions and remediation This report applies to botmux@3.18.9. - Review the evidence and your use of botmux@3.18.9 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 = 1 ``` ### 10. Medium: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 87.0% - **Path:** package.json - **Public source:** [View source]() The package runs a postinstall script automatically. 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:** 87.0% - **Path:** scripts/postinstall-bin.mjs - **Public source:** [View source]() On global installs, the script writes a launcher under the user's home directory. 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: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 87.0% - **Path:** scripts/install-path-entry.mjs - **Public source:** [View source]() The postinstall helper appends a PATH entry to shell startup files. 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:** 15 - **Optional dependencies:** 7 - **Peer dependencies:** 0 - **Development dependencies:** 19 - **Published dependency-graph edges:** 22 ### 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) - pm2 ^6.0.0 (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 3.18.9 (OptionalDependency) - botmux-darwin-x64 3.18.9 (OptionalDependency) - botmux-linux-arm64 3.18.9 (OptionalDependency) - botmux-linux-arm64-musl 3.18.9 (OptionalDependency) - botmux-linux-x64 3.18.9 (OptionalDependency) - botmux-linux-x64-musl 3.18.9 (OptionalDependency) ## Package metadata - **Package:** botmux - **Ecosystem:** npm - **Version:** 3.18.9 - **License:** MIT - **Version published:** 2026-08-31T08:35:09.435Z - **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:** 61,055 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
