SANS Assessment of Student Learning Plan (ASLP) Security Awareness Training

Which type of malware prevents you from accessing files stored on your computer?

1. Adware

2. Ransomware

3. Spyware

4. Trojans

The correct answer is: Ransomware

Ransomware is a type of malware specifically designed to deny access to files or systems until a ransom is paid to the attacker. It typically encrypts the files on the victim's computer, rendering them inaccessible. Victims are then presented with a ransom note demanding payment, often in cryptocurrency, in exchange for the decryption key that will restore access to their files. This tactic is highly effective because it leverages the urgency and need for users to regain control over their data, often leading individuals and organizations to comply with the demands. Understanding ransomware is critical for implementing effective security measures, such as regular backups and awareness training to mitigate the risks associated with this type of threat. Other types of malware mentioned, like adware, spyware, and Trojans, do not primarily focus on restricting access to files; instead, they have different mechanisms and objectives which do not involve immediate file encryption for ransom.
