Which MVT command is used by an incident responder to analyze decrypted backup files for detecting malicious events on iOS devices?

The command used by incident responders to analyze decrypted backup files for detecting malicious events on iOS devices is accurately identified as the option that employs the syntax "mvt-ios check-backup". This command is specifically designed for working with iOS backup files, allowing responders to examine the content of a decrypted backup for signs of malicious activity.

By utilizing this command, the responder can specify the output path where the results of the analysis will be saved, along with the path to the backup associated with a particular device ID (UDID). This targeted approach enables a comprehensive evaluation of the backup contents, looking for indicators of compromise or other anomalies that could suggest malicious events.

Other options either focus on different functionalities or are not structured to effectively analyze a decrypted backup for malicious activities. Understanding the purpose and correct usage of these commands is essential for efficient incident response when dealing with potential security breaches on iOS devices.
