Basically, ransomware itself belongs to the family of malware (malware) or malware. It just has the properties specifically as in the following explanation.
Know what ransomware is
Ransomware is a group of words taken from ransom which means ransom and malware which usually attack by locking important data or information from the device and then asking the victim for some money if you want to unlock it.
Typical ransomware attacks range from using Trojans (malware that will pretend to be an official app or file to be downloaded and opened) to running automatically from device to device without requiring interaction from the victim.
To be more effective, ransomware now often uses cryptocurrencies that not only promise wider transactions to different countries around the world, but can also make tracking down the identity of the perpetrator very difficult.
There are also many types of ransomware, but based on our searches, there are at least four categories that will divide them according to the type of attack.
Types of ransomware
encrypt ransomware A type of ransomware that attacks the victim by encrypting so many important files on the victim’s computer system that they are difficult to open without the description key.
Unencrypted ransomware Different from Encrypting Ransomware, this type will only secure access to the computer system without encrypting various files so that it is usually easy for experts to open again.
leak (Doxware) A type of ransomware that will not block access to a computer system or encrypt files but only secretly gather sensitive information and then blackmail victims by threatening to publish it.
Mobile ransomware Specifically, this type of ransomware is designed to attack mobile devices such as cell phones and tablets where the form of attack could be encrypting ransomware, unencrypted ransomware, or leaks.
As the old saying goes, prevention is definitely better than cure when dealing with a lot of ransomware in today’s world. Here are some tips so we can avoid one of them.
