Scenario 1
A financial company that makes loans to people wishing to buy pet dogs has suffered a ransomware attack. The group, calling themselves the CyberCat Criminals (CCC) compromised a user's (Bob) username and password and were able to access the company's server which was the main machine that runs all the company's systems. Although Bob worked in Finance, he had administrator privileges on the server machine. The criminals exfiltrated data about the company's customers and then encrypted the disks of the server, leaving a ransom note demanding payment in Bitcoin in exchange for a decryption key. The forensic team were unable to tell when the attack was carried out because no logging was being done on that machine.
