Carl works for a government agency that has suffered a ransomware attack and has lost access to critical data but does have access to backups. Which one of the following actions would best restore this access while minimizing the risk facing the organization?Group of answer choicesRebuild systems from scratchInstall antivirus softwarePay the ransomRestore backups

What are the characteristics of a ransomware attack? Select three answers.1 pointAttackers encrypt data on the device without the user's permission.Attackers make themselves known to their targets.Attackers demand payment to restore access to a device.Attackers display unwanted advertisements on the device.

A ransomware attack is when a malicious attacker gains remote access to a computer system, causes damage that makes the system un-usable, and then asks the organisation to pay money (the ransom). If the money is paid then the attacker restores the system to a working state. There are several types of ransomware attack. One type is for the attacker to encrypt critical files on the victim’s system using a symmetric encryption scheme like AES. When the ransom is paid, then the attacker can provide the secret key and the victim can decrypt the files. This question is about such an attack. (We stress that ransomware attacks are evil and often cause harm to ordinary people. The purpose of this question is not to encourage students to do ransomware attacks!) (a) Suppose an organisation always encrypts its files. Does that prevent this ransomware attack? (b) Give at least 3 reasons why is it more convenient for the attacker to just encrypt the files, rather than to download copies of them and then delete the originals on the victim system? (c) Can an organisation recover from such a ransomware attack if it is able to restore the encrypted files from backup? (d) Is there a way for an organisation to detect such a ransomware attack early by checking for AES encrypted files on their hard disks?
