Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Can remove unrelated or previous jssm executables from user/homebrew/package-manager bin directories during install. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Install Hook Abuse - **Selected version:** 2.0.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. Source inspection confirms a concrete install-time destructive action via rmSync against broad global/user binary paths. Package-aligned CLI env sync and auth behavior is not itself malicious, but the postinstall deletion behavior warrants blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-07-04T13:11:22.639Z - **Finished:** 2026-07-04T13:12:22.510Z - **Download time:** 510 ms - **Static scan time:** 486 ms - **AI review time:** 58874 ms - **Total time:** 59871 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:** The package has an npm postinstall hook that deletes existing jssm executables from user/global PATH locations. This is unconsented install-time filesystem mutation outside the installed package directory. - **Trigger:** npm install runs package.json postinstall - **Impact:** Can remove unrelated or previous jssm executables from user/homebrew/package-manager bin directories during install. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-07-04T13:12:22.510Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time deletion of same-named global binaries - **Attack narrative:** On installation, npm runs scripts/postinstall.mjs. The hook enumerates PATH and common global package-manager bin directories, then removes any executable named jssm that does not resolve into the newly installed package and is not under ~/.jssm. This install-time cleanup may be intended to prevent shadowing, but it is still unconsented destructive mutation of files outside the package install tree. - **Rationale:** Source inspection confirms a concrete install-time destructive action via rmSync against broad global/user binary paths. Package-aligned CLI env sync and auth behavior is not itself malicious, but the postinstall deletion behavior warrants blocking. - **Files touched:** package.json, scripts/postinstall.mjs, dist/index.cjs, ~/.bun/bin/jssm, ~/Library/pnpm/jssm, ~/.local/share/pnpm/jssm, ~/.yarn/bin/jssm, /usr/local/bin/jssm, /opt/homebrew/bin/jssm - **Network endpoints:** https://jssm-api.jutsu.ai/api, https://jssm.jutsu.ai, https://registry.npmjs.org/@saidulbadhon/jssm-cli ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json defines install-time postinstall: node scripts/postinstall.mjs, scripts/postinstall.mjs scans PATH and common global manager bins for executable named jssm, scripts/postinstall.mjs removes candidates with rmSync unless they resolve into this package or ~/.jssm, install hook can delete /usr/local/bin/jssm, /opt/homebrew/bin/jssm, ~/.bun/bin/jssm, pnpm/yarn global jssm without user consent, dist/index.cjs also contains CLI-triggered global self-update via npm install -g @saidulbadhon/jssm-cli@latest - **Evidence against:** dist/index.cjs network use is mostly package-aligned auth/project/env sync to jssm-api.jutsu.ai, dist/index.cjs .env upload/pull operations are invoked by explicit CLI commands and prompts, Auth token storage is under ~/.jssm/auth for the package's own service, No AI-agent control-surface writes found, No obfuscated staged payload or arbitrary remote code execution found ## Affected versions and remediation This report applies to @saidulbadhon/jssm-cli@2.0.1. - Avoid installing @saidulbadhon/jssm-cli@2.0.1. 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.
