# MAL-2026-10200: Malicious code in api-changelly (npm)


- **Type:** Malicious package
- **Package:** `api-changelly` (npm)

## What is MAL-2026-10200?

MAL-2026-10200 is a malicious package in api-changelly, published on 12 Jul 2026. 

### Official description

The package declares `preinstall: node index.js`, which runs automatically on `npm install`. index.js collects installer identifiers (os.hostname(), os.platform(), os.arch(), os.userInfo() username/uid/gid/shell, home directory, cwd) and executes `whoami` and `id` via child_process.exec, capturing their output. The combined JSON payload is POSTed to a hardcoded Burp Collaborator subdomain `https://1439tg4d02vixhxuj0gadpml4ca3ytmi.oastify.com/detox56`. The package name `api-changelly` impersonates the Changelly crypto-exchange brand and ships no legitimate functionality — the only behavior is the install-time beacon. This is the canonical dependency-confusion / reconnaissance-beacon shape targeting internal build systems that may resolve a private `changelly`-family dependency to this public package.

## What should I do about MAL-2026-10200?

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