Scenario:
Assume a disk from a former employee has been seized. It is believed that he sent a letter to the company threatening to unleash a virus on their network. The suspect denies sending the letter – this is a simple matter of finding the text from a deleted file (unallocated space).
After consideration, the text of interest has been identified as the key terms ($50,000 - ransom amount -, and ransom) and a phrase (unleash a virus), which were taken from the original letter received by the company.
