MITRE ATT&CK Enterprise TechniquesAI

T1070.004 File Deletion Stealth
Adversaries may delete files left behind by the actions of their intrusion activity.
T1210 Exploitation of Remote Services Lateral Movement
Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.
T1485 Data Destruction Impact
Adversaries may destroy data and files on specific systems or in large numbers on a network to interrupt availability to systems, services, and network resources.
Why these techniques?

Path traversal bypass enables remote authenticated attackers to delete arbitrary files (T1070.004), exploit the SSLVPN remote service (T1210), and cause data destruction through factory default reboot (T1485).
