Which versions of xdaxx are malicious?

The following npm versions of xdaxx are flagged malicious: 1.0.1. Treat any of these as compromised.

How do I remediate xdaxx if I installed it?

xdaxx establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

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

If xdaxx 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 xdaxx part of a known attack campaign?

Yes — xdaxx is associated with the IN-MAL-2026-016769 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 xdaxx across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for xdaxx (version 1.0.1).

What this malware does

The tarball contains a working browser-side account-takeover payload gated to run on noviembrenacional.com. When loaded in a logged-in victim's browser, it uses the victim's authenticated session to delete other users' accounts via WordPress/BuddyPress /members/<user>/settings/delete-account/ endpoints and, if the victim is the noviembrenacional administrator, changes the account email to [email protected] and triggers a password reset — completing a full account takeover. Execution progress is beaconed to a canarytokens.com URL controlled by the payload author. The same exploit is shipped in two forms: original.js in cleartext and i.js as a unicode-escape/hex-obfuscated copy (identifiers like _0xd243bf, strings built via \u00XX escapes and reversed-string tricks). The package has no lifecycle hooks and the declared main entry is missing, so installing or importing the package does not itself run the payload against the installer's machine; the npm registry is being used as hosting/distribution for a targeted attack tool against a specific third-party site.
