It then starts a detached process to clear and rewrite that terminal after npm exits. - **Trigger:** npm install -g checklist-tui in an interactive non-CI shell - **Impact:** Unconsented terminal hijacking and interruption during installation. - **Evidence paths:** package.json, scripts/postinstall.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T05:15:03.696Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall TTY discovery, terminal clearing, and detached relaunch - **Attack narrative:** The install hook walks parent processes to discover the real user TTY, opens it read/write, clears the screen, and synchronously launches the CLI during a global installation. It then launches a detached copy of itself with the TTY path and clears/writes the terminal again after npm completes. This is not needed for installation and disrupts the user's active shell without a user command. - **Rationale:** The package embeds deliberate, unconsented terminal takeover in postinstall, including a detached follow-up process. Although no exfiltration was found, this concrete install-time behavior is malicious. - **Files touched:** scripts/postinstall.js, dist/cli.js ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall locates and opens the user's controlling terminal., Install hook clears the terminal and synchronously launches the TUI., A detached child reopens and clears the terminal after npm completes. - **Evidence against:** No credential harvesting or network access occurs in the install hook., The runtime API sends only an explicitly entered checklist goal to the package service. ## 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.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.js ``` ### 3. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 6. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 7. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 8. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 9. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 10. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** dist/cli.js - **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): ```javascript stage = ast_semantic_analysis; reason = ast_alias_growth_limit_exceeded; limitedFiles = 1 ``` ### 11. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** scripts/postinstall.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = checklist-tui@0.1.2 matchedIdentity = npm:Y2hlY2tsaXN0LXR1aQ:0.1.2 similarity = 0.500 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 12. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 95.0% - **Path:** scripts/postinstall.js - **Public source:** [View source]() postinstall locates and opens the user's controlling terminal. Public source snippet (untrusted): ```javascript // npm 7+ runs postinstall in the background with no controlling terminal, so // `/dev/tty` fails. Walk parents until we find the real pty (the user's shell). function findTtyPath() { for (const candidate of ['/dev/tty', process.env.CHECKLIST_TTY]) { if (!candidate) continue try { fs.accessSync(candidate, fs.constants.R_OK | fs.constants.W_OK) return candidate ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, prepublishOnly - **Dependencies:** 2 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 5 - **Published dependency-graph edges:** 2 ### Published dependency entries - ink ^5.0.1 (Dependency) - react ^18.3.1 (Dependency) ## Package metadata - **Package:** checklist-tui - **Ecosystem:** npm - **Version:** 0.1.3 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-08-17T05:06:10.431Z - **Package first seen:** 2026-08-17T00:24:10.017Z - **Package last seen:** 2026-08-17T05:15:03.696Z - **Known versions:** 4 - **Latest version:** 0.1.3 - **Appeal under review:** No - **Description:** Write a note.
