What is MAL-2026-15895?
MAL-2026-15895 is a malicious package in easypanel-app, published on 4 Sep 2026.
Official description
The package's preinstall lifecycle script runs automatically on npm install and collects installer identity (os.hostname(), os.userInfo().username, process.cwd()) along with the names of CI-related environment variables. The collected data is JSON-serialized, base64url-encoded, chunked into DNS label form, and exfiltrated to a hardcoded third-party out-of-band collector at *.oob.lyomeri.com via both a dns.lookup() call and an HTTP GET to easypanel-app.daco3v4q6f49egu1ds1gwjnsjb88s5kcp.oob.lyomeri.com. The name mimics the legitimate Easypanel project and the shape (preinstall + host/username/cwd + OOB DNS+HTTP beacon to a per-package subdomain) is a dependency-confusion reconnaissance beacon, disclosing installer identity and internal-package-name existence to a third party regardless of any 'benign canary' self-label.
What should I do about MAL-2026-15895?
