Summary
Malicious code in eslint-plugin-mistica-local-rules (npm)
Details
package.json declares a preinstall hook that runs index.js automatically on npm install. index.js collects host identity (os.hostname(), os.platform(), os.arch(), os.userInfo() including uid/gid, shell, homedir, cwd) and the output of `whoami` and `id` via child_process, then POSTs the JSON payload to the hardcoded URL https://eucfugc8bk66haszliir75yd74dv1lpa.oastify.com/detox56 (a Burp Collaborator subdomain). The package ships no eslint rule implementation — its only effect on install is the recon/exfiltration beacon. The package name `eslint-plugin-mistica-local-rules` mimics the Telefónica Mistica design-system internal eslint-plugin namespace, consistent with a dependency-confusion attack against private-registry consumers.
