# MAL-2026-13966: Malicious code in tizen-webdriver-cli (npm)


- **Type:** Malicious package

## What is MAL-2026-13966?

MAL-2026-13966 is a malicious package in tizen-webdriver-cli, published on 13 Aug 2026. 

### Official description

On npm install, the package's postinstall lifecycle script collects host identifiers (os.hostname(), process.platform, process.arch, Node.js version, package name, and npm lifecycle event) and POSTs them as JSON over HTTPS to the hardcoded endpoint https://8kq1s58l.instances.poc.jchunt.top/tizen-webdriver-cli, with a 3-second timeout and errors silently swallowed. The behavior runs unconditionally at install time with no opt-in, no disclosure in normal install output, and no first-party relationship between the destination host and the package's advertised purpose (a Tizen WebDriver CLI, resembling shaka-project's generic-webdriver-server Tizen backend). The package name suggests dependency-confusion targeting of that legitimate project.

## What should I do about MAL-2026-13966?

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