File Type 1WhatsApp Encrypted Database File
What is a CRYPT file?
A CRYPT file is an encrypted file created by WhatsApp Messenger, a popular smartphone messenging application. It contains an archive of messages backed up from the WhatsApp application.
You can manually create CRYPT files. On your phone, select msgstore.db.crypt and saved in the following directory:
To restore your messages from a CRYPT file, uninstall your WhatsApp program, rename the file you want to restore to msgstore.db.crypt, install WhatsApp, and select when prompted.
NOTE: Since CRYPT files are saved in an encrypted format, they must be decrypted before being opened or restored. WhatsApp can decrypt your saved CRYPT files if you are logged in with the same Google account you used to create the backup. Alternatively, WhatsApp may request a "key file" saved on the device in order to decrypt the file.
File Type 2CryptXXX Ransomware Encrypted File
.CRYPT File Association 2
A CRYPT file is a file encrypted by the CryptXXX virus, which is a trojan horse utilized by cybercriminals. It contains a user's file, such as a .DOC or .MP4 file, that has been encrypted with the RSA4096 encryption algorithm to prevent it from opening. CRYPT files became prevalent in 2016 and are similar to .XXX files.
The CryptXXX virus is a type of ransomware where the purpose of the virus is to take your files hostage and force you to pay the perpetrator to unlock your files. The virus is a trojan horse that is typically introduced through spam email attachments or fake updates or downloads. Once the virus affects your computer it begins scrambling your files, renaming them, and encrypting them. The virus then generates a .TXT ransom note informing you of the takeover and what you need to do to recover your files. The note most likely demands a $500 ransom paid via Bitcoin.
If you back up your files you can execute a full system restore to remove the virus and retrieve your files. You may also be able to decrypt your CRYPT files using Kaspersky RannohDecryptor.
