Question

An engineer received a ticket to investigate a potentially malicious file detected by a malware scanner that was trying to execute multiple commands.

At which phase of the Cyber Kill Chain was this attack mitigated?

Explanation

In the Cyber Kill Chain framework, the installation phase occurs when the attacker establishes persistence by deploying malicious files or code onto the victim’s system. - The malicious file was detected by a malware scanner while attempting to execute commands. - Analysis showed that the file was downloaded after a phishing attack, indicating that the initial delivery was successful. - Because the malware was detected before execution, the attack was mitigated at the installation phase, preventing further exploitation and command execution.
