Locked Types of Ransomware

Types of Ransomware

Attackers may use one of several different approaches to extort digital currency from their victims:

Scareware : This malware poses as security software or tech support. Ransomware victims may receive pop-up notifications saying malware has been discovered on their system. Security software that the user does not own would not have access to this information. Not responding to this will not do anything except lead to more pop-ups.

Screen lockers : Also known simply as lockers, these are a type of ransomware designed to completely lock users out of their computers. Upon starting up the computer, a victim may see what looks to be an official government seal, leading the victim into believing they are the subject of an official inquiry. After being informed that unlicensed software or illegal web content has been found on the computer, the victim is given instructions on how to pay an electronic fine. However, official government organizations would not do this; they instead would go through proper legal channels and procedures.

Encrypting ransomware : Otherwise known as data kidnapping attacks, these give the attacker access to and encrypt the victim's data and ask for a payment to unlock the files. Once this happens, there is no guarantee that the victim will get access to their data back -- even if they negotiate for it. The attacker may also encrypt files on infected devices and make money by selling a product that promises to help the victim unlock files and prevent future malware attacks.

Doxware : With this malware, an attacker may threaten to publish victim data online if the victim does not pay a ransom.

Master boot record ransomware : With this, the entire hard drive is encrypted, not just the user's personal files, making it impossible to access the operating system.

Mobile ransomware : This ransomware affects mobile devices. An attacker can use mobile ransomware to steal data from a phone or lock it and require a ransom to return the data or unlock the device.
