Restoring files after encryption
Recovering files after an encryption attack can be a difficult task, but not always hopeless. Here are some recommendations for data recovery:
1. Isolation and removal of the threat: Before starting the recovery process, be sure to isolate the infected computer from the network or turn it off completely to prevent further spread of the encryptor.
2. Backup: If you have an updated backup copy of your files on a separate medium (for example, on external hard drives), it is best to use it for quick and effective recovery of lost data.
3. Check the available tools: At the moment, there are various free tool programs for checking the possibility of decrypting a file after an attack by encryptors of certain types (for example, Ransomware Decryptor Tool from Kaspersky Lab). They are based on pre-received key matrices or other information about a specific type of encryption used when creating a given encryptor.
4. Contact the experts: If you cannot restore the files yourself, it is recommended to seek help from information security professionals or companies that are experts in this field. They may have access to more advanced tools and techniques for decrypting data after an encryption attack.
It is important to note that successful recovery depends on the specific type of software (pattern) used to create threats, the availability of decryption keys, and other factors. Therefore, the possibility of full or partial success is not always guaranteed.
