# MAL-2026-6237: Malicious code in atlasora-api (npm)

## What is MAL-2026-6237?

MAL-2026-6237 is a malicious package in atlasora-api, published on 20 Jun 2026. 

### Official description

Package declares a postinstall hook ("postinstall": "node install.js") that runs install.js automatically on `npm install`. install.js imports https, fs, os, and child_process and collects host identifiers including os.hostname() and os.userInfo(), uses execSync for additional system enumeration, probes filesystem paths via fs.existsSync, and POSTs the collected data over an outbound https.request. This is the canonical install-time host-reconnaissance / exfiltration pattern: the package's only effect on installation is to harvest system identity and ship it off-host. There is no documented library functionality justifying the network beacon at install time.

## What should I do about MAL-2026-6237?

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