## What is MAL-2026-4270?

MAL-2026-4270 is a malicious package in clickpy, published on 22 May 2026. 

### Official description

On `require('clickpy')`, index.js collects host metadata via `os.hostname()`, `os.userInfo()`, `os.platform()`, `os.arch()`, `process.cwd()`, `process.pid`, and the current time, then issues an HTTPS GET to the hardcoded out-of-band host `fxpkkxatijbbyxuhdclqssj033zarohm1.oast.fun` with these values as query-string parameters (index.js:4 and index.js:25-29). oast.fun is the interactsh/OAST collaborator service used to receive callbacks from victim hosts; there is no legitimate purpose for a published library to beacon installer identifiers to such a host on import. Package metadata is empty (no description, no author), consistent with a throwaway recon/PoC exfiltration package.

The OpenSSF Package Analysis project identified 'clickpy' @ 1.0.1 (npm) as malicious.

It is considered malicious because:

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

## What should I do about MAL-2026-4270?

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