# Tool/Technique: Ghost (Cring) Ransomware
## Overview
Ghost (also referred to as Cring) is identified as a ransomware strain. Its primary purpose is to encrypt victims' files and hold them for ransom in exchange for a decryption key.
## Technical Details
- Type: Malware Family (Ransomware)
- Platform: Likely Windows (common target for ransomware, though specific platforms are unknown without the full article)
- Capabilities: File encryption, extortion.
- First Seen: N/A (Date not provided in context)

- TA0011 - Collection
- T1005 - Data From Local System
- TA0030 - Impact
- T1486 - Data Encrypted for Impact
## Functionality
### Core Capabilities
- Encrypting user files and system data to restrict access.
- Demanding cryptocurrency payment for the decryption key.
### Advanced Features
- N/A (Requires article content for specific features like defense evasion, specific encryption algorithms, or unusual spreading mechanisms).
