What is CryptBIT Ransomware

CryptBIT encrypts system-stored files making them no longer accessible and also demands victims to pay 400EUR for data decryption. Infections operating this way are therefore categorized as ransomware. During encryption, CryptBIT highlights blocked data by adding new extension (.cryptbit). In other words, a file like 1.pdf will change to 1.pdf.cryptbit and reset its original icon as well. The same change will occur with other file types encrypted by ransomware. The virus also changes desktop wallpapers and creates a text file named CryptBIT-restore-files.txt into each encrypted folder. This file instructs victims on how to decrypt their data.

The note displays text that all files have been encrypted and uploaded to external servers. It is, therefore, said that victims can recover their data, but have to send 400EUR (in bitcoins) to the attached crypto address. Cybercriminals also ask to include the victim’s e-mail address to which they promise to send the necessary file decryptor. Unfortunately, it is unclear how victims should do it. While performing cryptocurrency transfers, it is often (if not always) impossible to include additional information like e-mail. Thus, such technical misunderstandings already give strong reasons against trusting cybercriminals behind CryptBIT Ransomware. It is also possible that this ransomware is only a pilot version, and cybercriminals will distribute updated ransomware someday in the future. Whatever it is, paying the ransom is always not recommended. They can fool you, especially in cases when there are no direct channels to communicate through with swindlers. The best and most reliable way to recover your files is via recent backup copies if such can be retrieved from external storage devices. Otherwise, you can also try third-party decryption and recovery tools in our guide, however, we do not promise that they will actually help. Most file encryptions followed by ransomware attacks are complex to decipher using tools without the involvement of cybercriminals. It is also important to delete the virus first before trying any manual recovery methods. Follow our guide below to do it and explore all restoration alternatives.

How CryptBIT Ransomware infected your computer

There are multiple ways ransomware infections can penetrate systems – via malicious e-mail spam letters, trojans, fake software cracking tools, bogus updates/program installers, various network vulnerabilities, pirated or free software, and other similar channels as well. E-mail spam letters may look like something legitimate at first glance, but simultaneously contain malicious files or links designed to execute malware. The list of files cybercriminals tend to abuse consists of MS Office documents (.DOCX, .XLSX), PDFs, JavaScript files, Archives (.ZIP, .RAR), and Executables (.EXE). It is thus important to avoid such messages with traits we just described. In order to be protected against all compromised channels, one should avoid downloading content from unofficial and untrustworthy resources including dubious e-mail messages. Follow our guide below to learn more about protection against threats like CryptBIT Ransomware in the future.

2. Back up your files

idrive backup

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. CryptBIT Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox
