Ransomware accounts for up to 80 percent of all online threats in the United States.
Ransomware is ubiquitous: Locky, Petya, Goldeneye and Co. attack computers, encrypt data and release them after payment of a ransom. To date, effective protection has always been to keep an eye on surfing and opening mail attachments. But the expensive click on the wrong file or a prepared website can be done quickly and your own data is then unusable.
Now the security company Cybereason (English word play from "cyber" and "reason" - German: online reason) has published a tool called RansomFree. This promises a near-full protection against extortion trojans. The tool is free of charge and sets at the lowest common denominator of any Ransomware: the encrypting of files. The tool observes the system and detects unusual process activity and can stop you or alert the user.
The tool works on computers with Windows 7 to Windows 10 and the company promises to detect and stop Ransomware with up to 99 percent of meeting security. The tool uses Ransomware-typical behavioral patterns and deceptive technologies. It creates different folders with names that contain characters such as "!" Or "~". These characters are at the beginning in the ASCII table and would be the first encryption targets for Ransomware scanning.

If a process is created in these folders, RansomFree finds the source and isolates it, or locks it any access rights. The user then receives a message. This allows the user to delete the process or to continue its work.
Despite this promising workflow, you should continue to back up your data regularly and create backups of important files, folders, and hard drives. The tool is not a 100% protection against extortion trojans - but at least close. RansomFree is available at Cybereason as a free download.
