What does the adxaa malware do?

The tarball stages an obfuscated JavaScript payload (i.js, with an un-obfuscated copy in original.js) that gates on window.location.href containing 'noviembrenacional.com' and then, using the victim's authenticated session (fetch with credentials:'include'), exfiltrates the current page HTML and username to a canarytokens.com submit endpoint, POSTs to /members/ /settings/delete-account/, and for a specific target user overwrites the account email to a hardcoded attacker ProtonMail address (nyxalor_25@proton.me) via /my-account/editar-cuenta/ before triggering /wp-login.php?action=lostpassword to seize the account through password reset. The package's declared main (a.js) is absent from

Which versions of adxaa are malicious?

The following npm versions of adxaa are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate adxaa if I installed it?

adxaa is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed adxaa — how do I know if it already compromised me?

If adxaa was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is adxaa part of a known attack campaign?

Yes — adxaa is associated with the IN-MAL-2026-017967 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find adxaa across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for adxaa (version 1.0.0).

What this malware does

The tarball stages an obfuscated JavaScript payload (i.js, with an un-obfuscated copy in original.js) that gates on window.location.href containing 'noviembrenacional.com' and then, using the victim's authenticated session (fetch with credentials:'include'), exfiltrates the current page HTML and username to a canarytokens.com submit endpoint, POSTs to /members/<user>/settings/delete-account/, and for a specific target user overwrites the account email to a hardcoded attacker ProtonMail address ([email protected]) via /my-account/editar-cuenta/ before triggering /wp-login.php?action=lostpassword to seize the account through password reset. The package's declared main (a.js) is absent from the tarball and no lifecycle scripts are declared, so this code does not auto-execute on npm install or require against an arbitrary installer; the payload is staged on the registry for delivery to browsers on the targeted WordPress site.
