Detects when EC2 Serial Console Access is enabled for an AWS account. The EC2 Serial Console provides direct, text-based access to an instance's serial port, bypassing the network layer entirely. While useful for troubleshooting boot issues or network misconfigurations, enabling serial console access in production environments is rare and potentially dangerous. Adversaries may enable this feature to establish an out-of-band communication channel that evades network-based security monitoring, firewalls, and VPC controls. This access method can be used for persistent backdoor access or to interact with compromised instances without triggering network-based detection mechanisms.
