## Security analysis

### Published attack-surface review

- **Summary:** Installing the package activates an npm \`preinstall\` hook. It executes an obfuscated command that transmits host identity and working-directory data to an external Pipedream endpoint.

- **Trigger:** npm installation

- **Impact:** Unconsented installation-time host reconnaissance and data exfiltration.

- **Evidence paths:** package.json, preinstall.js, preinstall.json

- **Review source:** ai\_review

- **Reviewed:** 2026-07-12T23:05:25.269Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** hex-decoded shell command executed via \`child\_process.exec\`

- **Attack narrative:** On npm installation, \`package.json\` invokes \`preinstall.js\`. The script reads and hex-decodes a command from \`preinstall.json\`, then executes it through the shell. The decoded curl request POSTs the installing account name, current directory, and hostname to an external Pipedream collector without user consent.

- **Rationale:** This is concrete, obfuscated preinstall-time reconnaissance and exfiltration with no apparent package functionality. The lifecycle hook executes automatically during installation.

- **Files touched:** package.json, preinstall.js, preinstall.json

- **Network endpoints:** https://eo7o7j442dx6yl6.m.pipedream.net/

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** \`package.json\` runs \`node preinstall.js\` during npm preinstall., \`preinstall.js\` reads a hex command from \`preinstall.json\`, decodes it, and executes it with \`child\_process.exec\`., \`preinstall.json\` decodes to a curl POST to \`https://eo7o7j442dx6yl6.m.pipedream.net/\`., The POST collects \`whoami\`, \`pwd\`, and \`hostname\` automatically at install time.

- **Evidence against:** No package source files beyond the lifecycle payload were present., No evidence of a legitimate package function or user-invoked purpose was found.
