MAL-2026-6991 Malicious code in airkey-mfa-react (npm)

Package auto-executes a preinstall script (node test.js) on npm install that collects username, hostname, platform, Node version, and CI flag and POSTs them to https://eeazmrabqcquvqjfubjp6jkk2qq9p3acn.oast.fun/dex. index.js additionally runs whoami and id via child_process, gathers hostname/uid/gid/homedir/cwd/shell, and POSTs the results to https://rsnchacyin4dnjv0oc8prrwn1e77vzjo.oastify.com/detox56. The exfil payload carries a package: "company-internal-canary-2026", version: "99.0.0" label, indicating a dependency-confusion probe against an internal package namespace. Both destinations are out-of-band interaction service domains (interact.sh / Burp Collaborator) used to capture installer identifiers.

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.

The OpenSSF Package Analysis project identified 'airkey-mfa-react' @ 36.1.1 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.
