What is MAL-2026-17415?
MAL-2026-17415 is a malicious package in com.epi.e2e_test, published on 30 Sep 2026.
Official description
package.json declares a preinstall script that runs index.js on npm install. index.js collects host identifiers (os.homedir(), os.hostname(), os.userInfo().username, dns.getServers(), current working directory) along with the contents of the package.json and POSTs them over HTTPS to the hardcoded external host meta.brs.cx. This behavior fires automatically on install with no user interaction, and the collected data is characteristic of dependency-confusion / internal-name reconnaissance beacons used to identify targets for follow-on attacks.
What should I do about MAL-2026-17415?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
