PoshC2 is a post-exploitation framework that is often associated with malicious activity. The PoshC2 framework enables an attacker to disguise C&C communications as legitimate traffic from a PoshC2 agent installed on the victim device. After the victim establishes a successful TLS connection with the C&C server, the victim and the C&C server exchange HTTP requests and responses. HTTP responses from the C&C server include tasks such as "sleep" or "run command." HTTP requests from the victim include encrypted information such as metadata or command output.
Quarantine the device while checking for the presence of malware
Monitor and investigate unusual network activity for lateral movement or data exfiltration
