The package does this from an automatic postinstall hook without integrity verification or consent. - **Trigger:** npm install when Bun is not already available - **Impact:** Remote content can execute arbitrary commands with the installing user's privileges. - **Evidence paths:** package.json, scripts/install-bun.mjs, scripts/run-nanoagent.mjs, dist/bun-detect.js, dist/main.js, dist/tools/exec-tools.js, dist/graph/MemoryGraph.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T02:07:56.658Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote shell execution - **Attack narrative:** During npm install, the postinstall hook runs scripts/install-bun.mjs. If \`bun --version\` fails, it uses \`curl -fsSL https://bun.sh/install | bash\` on Unix or PowerShell \`irm ... | iex\` on Windows. This executes unpinned remote content before the user runs the CLI, with no hash/signature validation or confirmation. - **Rationale:** The automatic lifecycle hook creates a concrete unconsented remote-code-execution chain. Its apparent runtime-bootstrap purpose does not mitigate executing mutable network content during installation. - **Files touched:** package.json, scripts/install-bun.mjs - **Network endpoints:** https://bun.sh/install, bun.sh/install.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/install-bun.mjs automatically as postinstall., Installer executes a downloaded Bun installer through curl|bash or PowerShell irm|iex when Bun is absent., No checksum, signature verification, pinning, or user confirmation protects this install-time remote execution. - **Evidence against:** The inspected launcher only selects Bun/Node package entrypoints., No credential exfiltration was found in the inspected lifecycle and launcher code. ## Public findings ### 1.
