4. Try to Restore files encrypted by .CRYPTOSHIEL Virus
Try to Restore Files Encrypted by .CRYPTOSHIEL Virus
Ransomware infections and .CRYPTOSHIEL Virus aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
