Persistence

To be effective, the attacker must be able to maintain interactive persistence; they must have a two-way communication channel with the exploited system (interactive) that remains on the compromised system for a long period of time without being discovered (persistence). This type of connectivity is a requirement for the following reasons:

• Network intrusions may be detected, and the compromised systems may be identified and patched
• Some exploits only work once because the vulnerability is intermittent, or because exploitation causes the system to fail or to change, rendering the vulnerability unusable
• Attackers may need to return multiple times to the same target for various reasons
• The target's usefulness is not always immediately ...
