Summary
Malicious code in @outmarket/utils (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (2cd90f0d706cda01a5740f120f6e8d22ae57d907a5000854439c201b3c53a8c0)

package.json declares a postinstall lifecycle script that fires automatically on npm install. The inline node -e payload uses hex-encoded property names (\x6f\x73 for os, \x68\x6f\x73\x74\x6e\x61\x6d\x65 for hostname, \x75\x73\x65\x72\x49\x6e\x66\x6f for userInfo) to obscure that it reads os.hostname() and os.userInfo().username, then issues an HTTP GET to http://208.87.128.25:8888/?h=<hostname>&u=<username>. The destination is a bare IPv4 over cleartext HTTP — not a publisher domain or known infrastructure. The package is published under the @outmarket scope with a description identifying it as a dependency-confusion proof-of-concept, but the on-install behavior is indistinguishable from a real dependency-confusion beacon: any installer who resolves this public package in place of an internal @outmarket/utils will leak host identity to the hardcoded endpoint. Hex obfuscation of standard Node API names is evasion, not a legitimate engineering choice.
