Ransomware is a type of malicious software, also known as malware. It encrypts a victim’s data until the attacker is paid a predetermined ransom. Typically, the attacker demands payment in a form of cryptocurrency such as bitcoin. Only then will the attacker send a decryption key to release the victim’s data.
A number of ransomware variants have appeared in recent years, which we’ll describe in greater detail below. We will also explain how you can protect your system against future attacks.
Ransomware is typically distributed through a few main avenues. These include email phishing, malvertising (malicious advertising), and exploit kits. After it is distributed, the ransomware encrypts selected files and notifies the victim of the required payment.
Let’s break it down into 10 easy steps.
Ransomware variants of all types are discovered through the powerful research of Talos, our world-class threat intelligence group. To find out more about recent threats such as CryptoLocker, WannaCry, TeslaCrypt, Nyetya, and more, head over to the Talos blog.
