Malicious code in getd-typescript-eslint-rules (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
On npm install, the postinstall.js script collects the installer's hostname, OS username, platform, current working directory, CI environment markers (CI, BUILD_BUILDID, AGENT_NAME), and package name/version, then sends them as query parameters in an HTTPS GET to a hardcoded webhook.site collector (https://webhook.site/18dc4281-d366-438a-9186-76fbcd56ade5). Errors are swallowed so the install does not fail visibly. The package's own metadata declares it a typosquat targeting @getd/typescript-eslint-rules and frames the beacon as 'defensive security research,' but the on-install behavior identifies any installer (including internal CI build agents) to a third-party endpoint regardless of stated intent.
