Description
The npm package application_base version 9999.0.0 contains malicious code in its preinstall lifecycle hook. This code collects system and environment information including hostname, username, current working directory, npm registry, and CI repository environment variables. It then sends this data via an HTTP GET request to an external IP address, which is not a legitimate telemetry endpoint. This behavior is indicative of a dependency confusion reconnaissance attempt, allowing attackers to identify if an internal package name resolves to their public registry entry and gather information to target organizations for further attacks.
