Description
The npm package exiouss version 5.0.1 contains malicious code that imports the child_process module and sends POST requests to hardcoded endpoints, including a public Google domain and a non-resolvable internal domain likely used for attacker command and control. The code also repeatedly invokes ping commands, indicating potential active data exfiltration or reconnaissance behavior. This activity is inconsistent with normal HTTP client operations and suggests the package has been compromised to perform unauthorized network communication.
