# Tool/Technique: win.lumma
**Note:** The provided context only links to an entry about a sample named "win.lumma" analyzed by Guardio Labs. The full technical details, TTPs, and MITRE mappings are derived *only* from the sample identifier and are generalized due to the absence of the full article content. A detailed analysis would require the content of the linked article.
## Overview
win.lumma is likely a malware sample or family targeting the Windows operating system, categorized by Guardio Labs. Based on similar naming conventions, it is potentially related to infostealers or loaders, as hinted by the linked article title fragment ("...driving infostealer infections...").
## Technical Details
- Type: Malware family (Inferred)
- Platform: Windows (Inferred from "win.")
- Capabilities: Unknown (Requires article content)
- First Seen: Unknown
## MITRE ATT&CK Mapping
*Mapping is conjectural without the full article content. If related to infostealers:*
- TA0001 - Initial Access
- T1190 - Exploit Public-Facing Application (If delivered via a web vulnerability)
- TA0005 - Defense Evasion
- T1027 - Obfuscated Files or Information
## Functionality
### Core Capabilities
- Infiltration and data exfiltration (Highly probable based on context).
- Establishment of persistence (Likely for malware of this type).
### Advanced Features
- Unknown
## Indicators of Compromise

- File Names: [Not provided in context]
- Registry Keys: [Not provided in context]
- Network Indicators: [Not provided in context. All C2 communication would need external analysis or retrieval from the full article.]
- Behavioral Indicators: [Not provided in context]
## Associated Threat Actors
- Guardio Labs analysis suggests it is actively being deployed.
- [Specific threat actors unknown without article content]
## Detection Methods
- [Signature-based detection]: Requires specific file hashes or static signatures derived from the full sample analysis.
- [Behavioral detection]: Monitoring for unauthorized file access, network beaconing, or suspicious process injection common to Stealers.
- [YARA rules]: Not available from context.
## Mitigation Strategies
- Application Control to restrict execution of unauthorized binaries.
- Strong endpoint protection capable of detecting behavioral anomalies typical of commodity malware.
- User training regarding deceptive techniques (e.g., fake CAPTCHAs mentioned in the source link description).
