Only 8% of the victims recover all their data after a ransomware attack
Obtaining the decryption key does not imply restoring the encrypted files
Many ransomware attacks use a symmetric key encryption algorithm. Decryption and recovery are two distinct stages and issues that ransomware victims must face. Only 8% of the victims recover all their data.
Sometimes, decrypted files remain corrupted or still not usable. HelpRansomware has put together a guide on obtaining a decryption key and recover data from ransomware using the best decryption software.
What is a ransomware decryption key?
A ransomware decryption key is a set of instructions to decrypt files encrypted by ransomware.
How to get a decryption key?
In principle, you must be the owner of the encrypted file to get a decryption key.
The file creator or someone who knows how to decrypt it can release the decryption key.
Also, having access to your encrypted file does not mean you can decrypt it.
What is ransomware decryption software?
Ransomware decryption software is a program to decrypt your files if you are hit by ransomware.
It generates a decryption key based on information about this ransomware.
This software decrypts files and restores them to their original form.
Decryption software is designed to prevent system encryption and collect the data needed to decrypt files on a computer.
Can I decrypt a file without a decryption key?
You can use different basic techniques when attackers breach files without a key:
-
Brute-force attack: it consists of trying every possible key until you get the right one;
-
Frequency analysis: it relies on attempting many different combinations of characters and alphabets, but to understand the characters frequency of an encrypted file;
-
Temporal analysis: uses algorithms to detect and analyze abnormal behaviors;
-
Statistics: help create ransomware behavioral models and find vulnerabilities, but also search for the decryption key based on probability formulas;
-
Dictionary attack: another variant of the brute-force attack in an attempt to find decryption keys based on the words of a dictionary.
