## What is MAL-2026-2446?

MAL-2026-2446 is a malicious package in @corpweb-ui/wmkt-library, published on 3 Apr 2026. 

### Official description

index.js uses child_process to execute `whoami` and gather `hostname` information, then transmits results via https.get to api.telegram.org/bot — a well-known pattern for Telegram-bot-based C2/exfiltration. The package name mimics a corporate UI library but the code performs system reconnaissance and exfiltration of installer host data, with no legitimate UI-library functionality indicated at the entry point. Any installer or build system that pulls this package will leak the machine's user and hostname to an attacker-controlled Telegram bot on require/load. Three independent static detections (child-process + https exfiltration, nodejs system exfiltration, simple sysinfo exfiltration) corroborate a single small file implementing a classic recon beacon.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

The OpenSSF Package Analysis project identified '@corpweb-ui/wmkt-library' @ 99.99.11 (npm) as malicious.

It is considered malicious because:

- The package communicates with a domain associated with malicious activity.

## What should I do about MAL-2026-2446?
