# MAL-2026-13377: Malicious code in ezdiscordbots (npm)


- **Type:** Malicious package
- **Package:** `ezdiscordbots` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-13377?

MAL-2026-13377 is a malicious package in ezdiscordbots, published on 5 Aug 2026. 

### Official description

package.json declares a postinstall script `sudo node install.js` that runs install.js with root privileges on the installer's machine. Both install.js and index.js are heavily obfuscated (js-virtualizer / obfuscator.io family): hex-mangled identifiers, rotated string array, control-flow flattening, anti-debug regex checks, and a base64/percent-decoded string reconstructor. index.js concatenates four decoder-produced fragments and passes the result through Buffer.from(dora, 'base64').toString() at module load to materialize executable content that is not visible in the shipped source. The declared runtime dependencies include js-virtualizer (obfuscator) and node-linux (systemd/init daemon registration) — neither has any connection to the advertised Discord bot purpose, and node-linux provides the primitives to install a persistent root-level daemon. The combination of sudo-elevated postinstall, obfuscated self-decoding payload, and a Linux service-installer dependency is the canonical install-time RCE / persistence shape; installing this package causes attacker-controlled code to execute as root on the installer host.

## What should I do about MAL-2026-13377?

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