Ransomeware

What is Ransomeware???

Ransomware is a type of malicious software from cryptovirology that threatens to publish the victim's data or perpetually block access to it unless a ransom is paid. In simply it's blackmailing a user to paid them or otherwise user will lost their data.

While some simple ransomware may lock the system in a way that it is not difficult to reverse and more advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. Hope you get an idea about what is ransomware and what is does.

How to prevent???

There are a number of defensive steps you can take to prevent ransomware infection. These steps are a of course good security practices in general.

• Keep your operating system patched and up-to-date, to ensure you have fewer vulnerabilities to exploit.
• Don't install software or give it administrative privileges unless you know exactly what it is and what it does.
• Install anti virus software, which detects malicious programs like ransomware as they arrive, and white-listing software, which prevents unauthorized applications from executing in the first place.
• Back up your files, frequently and automatically. Otherwise you'll have to pay to get you data.

How to remove ransomeware??? 

These are the very important steps that you should follow.

• Reboot Windows 10 to safe mode
• Install antimalware software
• Scan the system to find the ransomware program
• Restore the computer to a previous state

But here's the important thing to keep in mind: while walking through these steps can remove the malware from your computer and restore it to your control, it won't decrypt your files. Their transformation into unreadability has already happened, and if the malware is at all sophisticated, it will be mathematically impossible for anyone to decrypt them without access to the key that the attacker holds. In fact, by removing the malware, you've precluded the possibility of restoring your files by paying the attackers the ransom they've asked for.

Ransomeware attacks...

• CryptoLocker, a 2013 attack that launched the modern ransomware age and infected up to 500,000 machines at its height
• TeslaCrypt, which targeted gaming files and saw constant improvement during its reign of terror
• SimpleLocker, the first widespread ransomware attack that focused on mobile devices
• WannaCry, which spread autonomously from computer to computer using Eternal Blue, an exploit developed by the NSA and then stolen by hackers
• NotPetya, which also used Eternal Blue and may have been part of a Russian-directed cyberattack against Ukraine
• Locky, which started spreading in 2016, was "similar in its mode of attack to the notorious banking software Dridex."
