## What is MAL-2026-14550?

MAL-2026-14550 is a malicious package in tset_racie, published on 26 Aug 2026. 

### Official description

tset_racie@1.0.3 ships a single 45KB obfuscator.io-style payload as its main entry (index.js). The file consists of a 551-entry RC4-encrypted string array, a base64+RC4 decoder, anti-debug self-defense that regex-tests function toString output to detect beautifiers/debuggers, and Function-constructor invocations that build a code string from concatenated decoded entries and immediately invoke it (e.g., `const d=a[...](Function, a[...](a[...](a[...DIBMW...], a[...BHoLQ...]), ');'));H=a[...WEBmW...](d);` followed by `WEBmW: function(H){return H();}`). Anyone who `require()`s this package immediately executes arbitrary code defined by the encrypted strings. The package metadata reinforces malicious intent: gibberish name (`tset_racie`), gibberish author (`ptchli_knldg`), empty description, no repository, no homepage, no dependencies, and no declared purpose — the disposable-publish shape typical of short-lived malicious uploads. The combination of a sole-file eval shell + runtime-assembled Function constructor + anti-debug guards + opaque metadata constitutes embedded malicious code; the encrypted payload's exact target (exfiltration, credential theft, dropper) cannot be statically resolved but the structural shape is unambiguous.

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-2026-14550?

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