# MAL-2026-13881: Malicious code in @assetshop/verify-cli (npm)


- **Type:** Malicious package
- **Package:** `@assetshop/verify-cli` (npm)
- **Published:** 12 Aug 2026

## What is MAL-2026-13881?

MAL-2026-13881 is a malicious package in @assetshop/verify-cli, published on 12 Aug 2026. 

### Official description

On `npm install`, the package's preinstall hook executes index.js, which collects installer identity and host information — `whoami` (via execSync), `os.hostname()`, `os.platform()`, `os.arch()`, `process.cwd()`, `os.homedir()`, and Node version — and transmits them to a hardcoded Interactsh/OAST callback subdomain at `5f8a1ed70fb7761d678agw9bapayyyyyb.oast.site` via an HTTPS GET (with the collected values placed in the URL path) and a DNS lookup of `${user}.${hostname}.assetshop-verify-cli.<oast-host>`. The package name in the `@assetshop` scope combined with the OAST beacon shape is the standard dependency-confusion reconnaissance pattern used to prove internal-name resolution against a private registry.

## What should I do about MAL-2026-13881?

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