MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

Improper binding of CDP relay on 0.0.0.0 directly exposes a debugging interface to external attackers, enabling remote exploitation of the public-facing service.
