What is Ransomware?
Ransomware is a type of malicious software that infects a user's computer and restricts access to it unless a ransom is paid. The hacker then holds the victim's computer or devices, such as mobile devices, for ransom. The cost of the ransom can range from a few hundred dollars to thousands, payable to cybercriminals in Bitcoin.
How does Ransomware Spread?
Ransomware is typically spread through phishing emails that contain a malicious attachment or through social engineering efforts that trick users into opening malicious attachments from unknown sources. Infection methods have evolved over time and are no longer limited to simple email messages or chat messages. Ransomware can also be spread through websites or even drive-by downloads. The latter is the most dangerous as it can be executed even when the user is not even surfing the web.
