Full Report
01flip is a new ransomware family fully written in Rust. Activity linked to 01flip points to alleged dark web data leaks.
Analysis Summary
# Tool/Technique: 01flip
## Overview
01flip is a newly identified ransomware family distinguished by being entirely written in the Rust programming language. Activity linked to this ransomware suggests an association with alleged dark web data leaks.
## Technical Details
- Type: Malware family (Ransomware)
- Platform: Multi-Platform (Implied by Rust compilation strength, though specific targets are not detailed in the context, Rust often targets Windows, Linux, and macOS)
- Capabilities: File encryption, data exfiltration precursor (implied by "dark web data leaks" association).
- First Seen: [Not specified in the context]
## MITRE ATT&CK Mapping
*Note: Specific mappings require deeper analysis of the malware's execution methods, but based on the description of ransomware activity:*
- **TA0865 - Impact**
- T1486 - Data Encrypted for Impact
- **TA0875 - Exfiltration** (Implied by association with data leaks, suggesting data staging might occur prior to encryption)
- T1041 - Exfiltration Over C2 Channel (Potential)
## Functionality
### Core Capabilities
- Data encryption (Ransomware operation).
- Written entirely in Rust, providing potential for cross-platform compatibility and evasion benefits compared to traditional languages.
### Advanced Features
- Association with alleged dark web data leaks suggests a double-extortion model involving publicizing stolen data if the ransom is not paid.
## Indicators of Compromise
- File Hashes: [Not provided in the context]
- File Names: [Not provided in the context]
- Registry Keys: [Not provided in the context]
- Network Indicators: [Not provided in the context]
- Behavioral Indicators: [Not provided in the context]
## Associated Threat Actors
- Not explicitly named; activity is linked to alleged dark web data leaks.
## Detection Methods
- Signature-based detection: [Not provided in the context]
- Behavioral detection: Detection focusing on file system modifications characteristic of encryption routines or process behavior indicative of a Rust binary execution.
- YARA rules: [Not provided in the context]
## Mitigation Strategies
- Prevention measures: Implementing robust backup strategies (following 3-2-1 rule).
- Hardening recommendations: Employing application whitelisting to restrict execution of unknown binaries, especially those written in newer languages like Rust which might bypass older heuristics.
## Related Tools/Techniques
