The product appears to contain benign or useful functionality, but it also contains code that is hidden from normal operation that violates the intended security policy of the user or the system administrator.
MITRE ATT&CK techniques associated with this weakness class (mapped via MITRE CAPEC). A vulnerability of this type could let an adversary carry out:
A stage-by-stage walkthrough of the attack, mapped to the real MITRE ATT&CK tactics for this weakness — what the attacker is trying to do, what's at risk (what can be stolen or damaged), and how you defend. Understanding the playbook is how you shut it down.
Stay in even after reboots, patches, or credential changes.
Startup hooks, scheduled tasks, config, and accounts the attacker can plant a backdoor in.
Integrity monitoring of code, config, and scheduled tasks; short-lived credentials.
This is a defensive, conceptual walkthrough for education — stages reflect MITRE ATT&CK tactics associated with this weakness class, not a working exploit. Not every attack uses every stage.
