GCIH · Question #434

Deleting an attacker's scheduled tasks on a victim host is something that would typically occur during which phase of incident handling?

The correct answer is D. Eradication. Removing attacker artifacts like scheduled tasks falls under the Eradication phase, where all malicious footholds are eliminated from the compromised system.

Why each option

Removing attacker artifacts like scheduled tasks falls under the Eradication phase, where all malicious footholds are eliminated from the compromised system.

AIdentification

Identification (also called Detection/Analysis) involves discovering and confirming that an incident has occurred, not removing attacker artifacts.

BRecovery

Recovery focuses on restoring systems to normal operation after eradication is complete, not on removing malicious artifacts.

CPreparation

Preparation occurs before any incident and involves building policies, tools, and response capabilities, not responding to active attacker activity.

DEradicationCorrect

Eradication is the incident handling phase focused on completely removing the attacker's presence and any mechanisms they used to maintain access or execute code, such as scheduled tasks, malware, or backdoors. Deleting scheduled tasks directly addresses persistence mechanisms the attacker installed. This phase follows Containment and precedes Recovery to ensure the environment is clean before restoration.
