Malicious code in alipclutch-baileys (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The URL is not present as a string literal — it is assembled at runtime from a decimal-ASCII array via String.fromCharCode(104,116,116,112,115,58,47,47,102,105,111,114,97,46,110,105,120,101,108,46,109,121,46,105,100,47), and the associated internal key prefix uses unicode-escaped characters (`\u004E\u0049\u0058\u0045\u004C_LATEX_` / `_HYPERLINK_` / `_CITATION_`) so the 'NIXEL'/'fiora' identifiers do not appear in plaintext anywhere else in the package. The advertised purpose of the library is to send WhatsApp messages on behalf of the caller; the caller does not opt into any attribution to fiora.nixel.my.id, and no configuration surface exposes this destination. The behavior is a covert attribution/traffic-attribution side-effect using the caller's WhatsApp session — no credential theft, environment scraping, remote code execution, filesystem persistence, or backdoor is present in this code path; recipients of the caller's messages who click the media preview would be directed to the author-controlled host. The obfuscation choices (charcode-assembled destination plus unicode-escaped brand token) are consistent with deliberate concealment of the destination from source review rather than incidental minification. ## Source: ghsa-malware (09e5b87da389cf9d1ea5964b0bd5f22a4ac0dab50847448dc1352158633f09f1) 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.
