Week 4 – Ransomware

What is?

Ransomware is malware that employs encryption to hold a victim’s information at ransom. A user’s critical data is encrypted so that they cannot access personal files and a ransom is demanded to provide access to the files.

Many variations of ransomware exist. Often ransomware (and other malware) is distributed using email spam campaigns or through targeted attacks. Malware needs an attack vector to establish its presence on an endpoint. After presence is established, malware stays on the system until its task is accomplished.
