What are ransomware and prevention and how is it performed?

Ransomware is malware that performs encryption to a victim's information at ransom. So the victim can't get access to his computer and this type of attack is mainly done for money and Revenge purposes.

How ransomware enters into the victim device:- hackers use different tools and methods to make ransomware undetectable.

Methods of infecting:- ransomware can be entered into the victim devices through physical access like USB virus or through some malicious cables it is mainly happening in charging ports.

And it can also spread through the internet with spam emails, malicious software, clickjacking.....etc.

TYPES OF RANSOMWARE:

There are two main types of ransomware:

Crypto ransomware: Encrypts valuable files on a computer so that the user cannot access them.

Locker ransomware: Does not encrypt files. Rather, it locks the victim out of their device, preventing them from using it. Once they are locked out, cybercriminals carrying out locker ransomware attacks will demand a ransom to unlock the device.


Steps to recover your data:

Step 1: Do not pay the ransom because there is no guarantee that the ransomware creators will give you access to your data.


Step 2: Find any available backups you have, and consider keeping your data backups in secure, off-site locations.


Step 3: If there are no backups, you have to try decrypting the data locked by ransomware using these ransomware decryptors.

Sometimes when u download applications from malicious websites it will ask you to disable antivirus to proceed with further installation don't do that it might contain ransomware. 


TYPES OF RANSOMWARE EXTENSIONS

The ransomware includes a particular file extension, you can point it out with some of the extensions defined below

.ecc, .ezz, .exx, .zzz, .xyz, .aaa, .abc, .ccc, .vvv, .xxx, .ttt, .micro, .encrypted, .locked, .crypto, _crypt, .crinf, .r5a, .XRNT, .XTBL, .crypt, .R16M01D05, .pzdc, .good, .LOL!, .OMG!, .RDM, .RRK, .encryptedRSA, .crjoker, .EnCiPhErEd, .LeChiffre, .keybtc@inbox_com, .0x0, .bleep, .1999, .vault, .HA3, .toxcrypt, .magic, .SUPERCRYPT, .CTBL, .CTB2, .locky or 6-7 length extension consisting of random characters

Conclusion:- sometimes we can't decrypt the ransomware than we have only one option to pay but don't we. 

If you pay also sometimes the decryption key will not be given by the hackers.
