loadninja-shared@9.9.99 is a dependency-confusion package targeting an internal/private package namespace. package.json declares "postinstall": "node beacon.js", which fires automatically on npm install. beacon.js reads os.hostname() and transmits it — together with a nonce and the package name — to the attacker-controlled out-of-band domain tspeuj1fodn3cj8v30uck2fs4jaby1mq.oastify.com (Burp Collaborator infrastructure) over both a DNS lookup (dns.lookup(NONCE + '.' + host63 + '.' + HOST,...)) and an HTTPS POST. The version 9.9.99 is the canonical high-version trick used to win npm resolution against a legitimate internal package of the same name, capturing misrouted internal builds. Although a code comment labels the file a "benign PoC," the behavior is identical to a live dependency-confusion exploitation beacon: any installer that resolves this package leaks its host identifier to a third-party callback domain without consent.

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.
