.CRYPT1 File Extension
File Type 1UltraCrypter Ransomware Encrypted File
What is a CRYPT1 file?
A file with a .crypt1 extension is a file that has been encrypted by the UltraCrypter virus, which is a variant of CryptXXX ransomware. It is encrypted so it is not possible to open the file by simply changing the file extension.
UltraCrypter is a type of malware utilized by cybercriminals that takes your files hostage and forces you to pay the perpetrator to unlock your files. It may be introduced to your computer through an executable file disguised as another type of file. This is typically done through malicious ads on compromised websites or email spam with attached files disguised as other files.
When the ransomware runs on your computer, it encrypts and renames standard files that are important to you with a .crypt1 extension. The files are typically documents, images, videos, and backup files, such as .PDF, .JPG, and .DB files. For example, an example.jpg file becomes example.jpg.crypt1. The virus changes the desktop wallpaper then generates a .HTML ransom note informing you of the takeover and what you need to do to recover your files, which is typically a payment via Bitcoin.
CRYPT1 files became prevalent in May 2016 and are similar to encrypted .CRYPT files. Currently, there is no program available to effectively restore your files. If you have a recent backup of your files, you can perform a system restore.
Programs that open CRYPT1 files
File Type 2WhatsApp Encrypted Database File
.CRYPT1 File Association 2
A CRYPT1 file is an encrypted database created by WhatsApp Messenger, an Android messenger application. It contains a 256-bit AES encrypted backup of downloaded sticker packs (stickers.db.crypt1), chat settings (chatsettingsbackup.db.crypt1), or your contacts' status rankings (statusranking.db.crypt1).
The .crypt1 extension is appended to a .DB file to create a .db.crypt1 file, which is used by WhatsApp to back up a user's stickers, chat settings, or contacts' status rankings. These files are similar to .CRYPT7, .CRYPT8, and .CRYPT12 files, which are encrypted database files that back up your WhatsApp message history.
If you are looking to decrypt a CRYPT1 database to view the settings or stickers it contains, you must first locate your WhatsApp key file, which stores the database's encryption key. The key file is stored in the following location: /data/data/com.whats.app/files/key. Note that, at this time, there is no known program that can decrypt a CRYPT1 database.
CRYPT1 files are located on the SD cards of Android devices with WhatsApp Messenger installed. You can find them in the following directory: /sdcard/WhatsApp/Backups.
NOTE: Only the Android version of WhatsApp Messenger creates CRYPT1 files. The iOS and desktop versions of WhatsApp messenger do not create CRYPT1 files.
stickers.db.crypt1 - An encrypted backup of the stickers you've sent and received through WhatsApp.
chatsettingsbackup.db.crypt1 - An encrypted backup of your WhatsApp chat settings.
statusranking.db.crypt1 - An encrypted backup of your WhatsApp contacts' status rankings.
How do I open a CRYPT1 file?
CRYPT1 files are typically not meant to be opened. If you ever need to migrate or restore your WhatsApp data, you can use your CRYPT1 files to restore your downloaded stickers, chat settings, and contacts' status ranking. To do so, ensure the stickers.db.crypt1, chatsettingsbackup.db.crypt1, and statusranking.db.crypt1 are present within your Google Drive backup or SD card when you install and log in to WhatsApp.
