## What is MAL-2026-12215?

MAL-2026-12215 is a malicious package in statist-browser-typed-client-sme.salary.web.metrics, published on 5 Aug 2026. 

### Official description

On require(), _adapter.js fetches a platform-specific binary payload from split-string-obfuscated Cloudflare Workers hosts (oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT resolver fallback under *.dl.well1.site (tin.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site). The fetched bytes are written to /var/tmp or %TEMP% under cover-story names (.cache_<rand> on POSIX, dotnet_diag_<rand>.exe on Windows), chmod 0755'd on POSIX, and spawned detached via /bin/sh or cmd.exe. There is no hash or signature verification of the fetched payload. Endpoint hostnames and resolver domains are reconstructed at runtime by joining literal fragments to evade static string matching. The package presents itself as an observability/metrics bridge, but the shipped behavior on import is download-and-execute of an opaque attacker-controlled binary, giving whoever published this full code execution on any host that installs or imports the package.

## What should I do about MAL-2026-12215?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
