Malicious code in eslint-plugin-skywagon-web (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (3c5d134d2e79b24ed65d2998520db05b5cc86b251ae579a6d8cec6d8fe02340f) eslint-plugin-skywagon-web@100.0.0 ships an index.js that is executed via a preinstall lifecycle script on `npm install`. The script collects installer-side identifiers — os.hostname(), os.userInfo().username, os.homedir(), process.cwd(), dns.getServers(), and the contents of the package's package.json — and POSTs them over HTTPS to the hardcoded external collector eo1blcdjptwydyq.m.pipedream.net. A source comment ("replace burpcollaborator.net with Interactsh or pipedream") shows the file is a dependency-confusion exfiltration template repurposed as a live payload. The implausibly high version number (100.0.0) is consistent with a dependency-confusion lure intended to override an internal package of the same name during resolution.
