## What is MAL-2026-16024?

MAL-2026-16024 is a malicious package in blueai-cli, published on 7 Sep 2026. 

### Official description

package.json declares `"preinstall": "bun run index.js"`, causing npm install to execute a 499KB obfuscator.io-style file via the Bun runtime. index.js uses hex-mangled identifiers, a rotating string array (`_0x71ec`), a PBKDF2-derived key with multi-round RC4/XOR string encryption (class `du`), and installs a decrypt sink on `globalThis`, alongside an embedded base64 blob. The payload contains GitHub API logic that validates a token against `https://api.github.com/user` and enumerates organizations via `/user/orgs`, parsing `X-OAuth-Scopes` for `repo`/`workflow`/`public_repo` and reading `X-GitHub-OAuth-Token-Expiration`, returning a `{valid, user, scopes, expiry, orgs, hasRepoScope, hasWorkflowScope}` structure characteristic of a GitHub personal-access-token harvester. The advertised purpose (a media CLI targeting bluemediagroup.cn endpoints) does not require an obfuscated install-time blob, an alternate runtime, or inspection of installer-owned GitHub credentials; the shipped `dist/` tree is unobfuscated, confirming the preinstall file is an evasion-layered install-time execution channel independent of the library.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-16024?

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