Explain that the latest type of attack in this category is known as ransomware, which is a malware attack on the host system that denies access to the user and then offers to provide a key to allow access back to the user’s system and data for a fee.
Compare and contrast the two different types of ransomwares: lockscreen and encryption.
Lock screen ransomware denies access to the system by disabling access to the desktop and preventing the user from bypassing the ransom screen that demands payment for access.
Encryption ransomware is more severe, as it requires payment upfront to access one’s hard drive after their information has been encrypted.
Illustrate the three examples of ransomware activities highlighted in the text and stress to students that these types of attacks occur daily, and an information security team must be on guard to overcome and nullify these.
