Asked in the virtual onsite stage. The discussion covered incident response across macOS, Linux, and Windows, including process-tree analysis.
Address containment, evidence preservation, triage, eradication, recovery, and lessons learned. Name platform-specific commands and explain how you would distinguish legitimate parent-child relationships from suspicious execution.
