Malicious code in sm-session (npm)
The npm package sm-session (version 99.0.1) contains malicious preinstall and postinstall lifecycle scripts that beacon to a hardcoded IP address (16.192.173.5) over plain HTTP, exfiltrating installer host information. This is a dependency-confusion reconnaissance attack designed to identify which environments resolve the package name.

Malicious code in sm-payment (npm)
The npm package sm-payment version 99.0.1 contains malicious preinstall and postinstall lifecycle scripts that contact a hardcoded bare IP address (http://16.192.173.5) over plain HTTP during installation. The behavior is consistent with reconnaissance beacons for dependency-confusion or namesquatting attacks.
