What is BlackClaw Ransomware
BlackClaw is a recent ransomware infection that uses AES and RSA algorithms to encrypt user’s data. Some experts similized it with another file-encrypting virus called Billy’s Apocalypse because of similar ransom note details, however, as research continued, it turned out that there is no correlation with it. BlackClaw is an independent piece that assigns .apocalypse or .bclaw extensions to encrypted files. For example, a file like
1.mp4 will suffer a change to
1.mp4.apocalypse. After these changes have been applied, users no longer have access to their data. The next step of BlackClaw after blocking data is dropping a text file (RECOVER YOUR FILES.hta or RECOVER YOUR FILES.txt) that notifies people about encryption.

BlackClaw 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 simple interface. You can read more about iDrive cloud backup and storage here.
3. Do not open spam e-mails and protect your mailbox
