It collects local secrets, sends an archive to Telegram, and attempts to republish the victim’s npm packages with the payload installed. - **Trigger:** npm installation invokes the postinstall script. - **Impact:** Loss of credentials and private files, followed by compromise of packages owned by a stolen npm token. - **Evidence paths:** package.json, dist/script.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T11:48:44.680Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Broad local secret collection, Telegram exfiltration, and npm package infection using stolen tokens. - **Attack narrative:** On installation, the package scans the user’s home and project directories for secrets, credentials, wallet data, npm configuration, and environment values. It builds and uploads an archive of the findings to Telegram. It then collects npm tokens, identifies packages belonging to those token holders, downloads and modifies them to run this payload at postinstall, and republishes them using the stolen credentials. - **Rationale:** This is a concrete install-time credential theft and npm supply-chain propagation payload. The source directly implements collection, exfiltration, token use, and package republishing. - **Files touched:** dist/script.js, package.json, scripts.json, .npmrc, report-\/files/\*, report-\.zip - **Network endpoints:** https://api.telegram.org, https://registry.npmjs.org/-/whoami, https://registry.npmjs.org/-/v1/search ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs dist/script.js after installation., The script searches the home directory and project paths for sensitive files, SSH keys, cloud credentials, npm configuration, and relevant environment variables., It copies collected files into a report, archives the report, and uploads it to Telegram., It extracts npm tokens, enumerates the token holder’s packages, adds its own postinstall hook, copies its payload, and publishes altered packages. ## Public findings ### 1.
