Return attacks cause damage and inconvenience to innocent systems that share network or system resources with the system being attacked. DO NOT get into a verbal or textual exchange with the suspected attacker, as the actual identity is often purposefully obscured, and your response may abuse an innocent third party.
Can you disconnect a machine from the network?
DO NOT disconnect the machine from the network. This will prevent the investigator from examining the attack as it occurs and collect real-time data to be used against the attacker. DO NOT turn the machine off or reboot unless instructed to do so by a security team member.
Can an attacker restart after rebooting?
It is possible that the processes left by an attacker may not get restarted after rebooting, which may make it more difficult for a Network Security consultant to determine the root cause of the problem.
