What is the correct order of troubleshooting methodology after a file share is infected with CryptoLocker?

The correct order of troubleshooting methodology after a file share is infected with CryptoLocker starts with identifying the problem. This initial step is crucial as it allows you to understand that an infection has occurred, and determine the extent of the impact.

Following this, establishing a theory involves hypothesizing about the cause of the issue and potential solutions. This stage requires gathering information about the infection, such as when it occurred and how it managed to infiltrate the system.

Next, testing the theory allows you to verify if the hypothesized solution can effectively address the problem. It involves applying a potential fix or corrective action while monitoring the system's response to see if it mitigates the ransomware's effects.

Establishing a plan is essential to ensure the selected remediation method is implemented correctly and comprehensively, detailing steps like data recovery or re-establishing file shares once the threat is neutralized.

Finally, verifying functionality confirms that the system is back to normal and that the infection has been successfully removed. This last step is critical to ensure operational continuity.

Understanding this order helps reinforce the importance of a structured approach to troubleshooting, especially in scenarios involving cybersecurity threats like CryptoLocker.
