Analysis Summary
# Tool/Technique: Arcane Infostealer
## Overview
Arcane is a newly identified information stealer malware designed to compromise user data, particularly targeting users who download game cheats, often distributed via platforms like YouTube and Discord. It excels at broad data theft across various application types, including VPN clients, messengers, crypto wallets, and gaming platforms.
## Technical Details
- Type: Malware family (Infostealer)
- Platform: Windows (Implied by targeted applications like Outlook, browser focus)
- Capabilities: System profiling, credential harvesting (browsers, applications), cookie theft, screenshot capture, Wi-Fi password retrieval.
- First Seen: Information not explicitly provided in the text, but noted as "New."
## MITRE ATT&CK Mapping
Specific direct mappings were not listed in the source, but based on capability, the following are strongly implied:
- **TA0001 - Initial Access** (via distribution through game cheats)
- **T1189 - Drive-by Compromise** (Potential if malicious content is downloaded directly)
- **TA0005 - Defense Evasion**
- **T1027 - Obfuscated Files or Information** (Common for malware distribution)
- **TA0009 - Collection**
- **T1005 - Data from Local System** (Stealing configuration files, credentials)
- **T1056 - Input Capture**
- **T1056.001 - Keylogging** (Implied by broad credential theft, though not explicitly stated)
- **T1113 - Screen Capture**
- **T1113.001 - Local Screen Capture** (Explicitly mentioned: captures screenshots)
- **TA0010 - Exfiltration**
- **T1041 - Exfiltration Over C2 Channel** (Implied step after collection)
## Functionality
### Core Capabilities
- **System Profiling:** Gathers hardware and software details (OS version, CPU, GPU, installed antivirus, browsers).
- **Credential Harvesting:** Steals saved logins, passwords, and cookies from web browsers (specifically Chromium-based browsers).
- **Application Data Theft:** Targets configuration files and account data from a wide array of applications.
### Advanced Features
- **Broad Target Scope:** Exfiltrates information from specific clients including OpenVPN, NordVPN, Signal, Discord, Telegram, Outlook, Steam, Epic Games, Roblox, and numerous cryptocurrency wallets (e.g., Exodus, Electrum).
- **Screenshot Capability:** Actively captures screenshots of the user's desktop activity.
- **Wi-Fi Credential Retrieval:** Retrieves saved Wi-Fi network passwords from the compromised system.
- **Recruitment/Promotion:** Operators actively tried to recruit content creators on Discord to promote the malware in exchange for a fee.
## Indicators of Compromise
- File Hashes: [Not provided in the text]
- File Names: [Not provided in the text]
- Registry Keys: [Not provided in the text]
- Network Indicators: [Not explicitly provided in the text, only C2 function implied]
- Behavioral Indicators: Infection vector via game cheats distributed through YouTube/Discord channels; system profiling; active screenshot capture; collection of specific application data.
## Associated Threat Actors
- Unspecified threat actors/operators, noted as engaging in recruitment activities to spread awareness/distribution.
## Detection Methods
- Signature-based detection (requires creation based on new samples).
- Behavioral detection focusing on unauthorized access to credential stores, configuration files for banking/VPNs/messengers, and unusual screen capture activity.
- YARA rules: [Not available in the text]
## Mitigation Strategies
- **Avoidance:** Strictly avoid downloading unsigned, pirate, or cheat tools, as they serve as the primary infection vector.
- **Security Awareness:** Users must be aware of the risks associated with downloading such tools from non-official sources like community channels (YouTube/Discord).
- **Post-Infection Cleanup:** Requires changing passwords for every compromised website and application (a "massive time sink").
