Overview
What is ransomware
Ransomware is a kind of malware that is installed illegally on a PC regardless of user's intention, and it is a hacking method that requires Bitcoin after accessing and encrypting major files on the PC. Ransomware infection is difficult to treat, and even if you pay a hacker, there is no guarantee that you will receive the decryption key. Therefore, prevention is more economical than recovery, and it is often the only alternative that can protect your PC.
ShieldOS is a ransomware expert prevention solution that prevents tampering of your valuable data from ransomware.
Data protection technology
The engine core of ShieldOS runs in the kernel mode of the OS and controls all file I/O access to the local disk. It protects user data by blocking unauthorized and abnormal processes and unauthorized access in real time.
* Patent application : 10-2016-00818241 Ransomware blocking system and method based on whitelist and blacklist
Principles of operation
Existing working principle
- After reading the data file, use the method of encrypting and deleting the existing data
- Change the folder name or file name to a form that cannot be read in file explorer
- Reading data files and leaking them to c&c servers, etc.
How ShieldOS works
- Policy management of processes that can access each data file format
- Detects all requests for shieldos core data files in the OS kernel location
- Determine whether to allow or block by judging whether the target file is an authorized or unauthorized process
- Blocks leakage by malicious code by even blocking data file reading
How to block ransomware
Approved processes in the black & white list method allow access and block access suspected as ransomware. It also protects data files from being leaked to the outside from malicious code.

Strengths
Data file protection
It protects data files by blocking unauthorized and abnormal processes or unauthorized actions in real time.
Block forgery

Provides a function to block illegal external leaks by malicious codes such as ransomware.
All file I/O detection
The engine core of ShieldOS runs in the kernel mode of the OS and detects all file I/O to the local disk to completely control process access.
Comfortable use
Unlike antivirus or backup solutions, ShieldOS does not clean, backup, or detect, so it does not burden the system. It can run smoothly even with low PC specifications, and you can use the PC environment you are using without worrying about ransomware.
Various extension protection
It protects various types of file extensions such as documents, images, audio, video, and compressed files by default, and users can specify additional protection extensions themselves.
