This is a concrete credential/data-exfiltration chain. - **Trigger:** npm installation runs postinstall, which executes test.js and calls from\_str(). - **Impact:** Local browser/profile or other user data can be stolen at install time. - **Evidence paths:** package.json, test.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:14:57.841Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated recursive file harvesting and multipart HTTP exfiltration. - **Attack narrative:** On install, package.json runs test.js, which calls the exported from\_str function. In index.js that export launches obfuscated workflows: one derives OS locations, recursively walks and reads files, then packages data with form-data and posts it through axios. The same install-time path also gathers additional local data before upload. The hidden destination does not reduce the confirmed collection-and-exfiltration behavior. - **Rationale:** The postinstall hook directly triggers heavily obfuscated local-file collection and axios multipart upload code. This is malicious install-time data exfiltration, not package-aligned behavior. - **Files touched:** package.json, test.js, index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node test.js\` in postinstall., test.js imports and invokes \`from\_str()\` during installation., index.js exports an obfuscated \`from\_str\` routine that starts two async workflows., index.js imports fs, path, os, child\_process, axios, and form-data., One workflow recursively enumerates files below OS-derived locations and reads files., Read data is assembled into multipart FormData and sent with axios. - **Evidence against:** No benign package functionality or documented purpose is present., No plaintext endpoint is recoverable without executing the obfuscated payload. ## Public findings ### 1.
