Avalon Malware Framework: CrownX Ransomware Analysis & Defense

) API.

When the attacker interacts with a compromised host via a Telegram bot interface, they type instructions in conversational English. This text is forwarded directly to Groq’s public inference API (api.groq[.]com/openai/v1/chat/completions). The LLM translates the attacker’s plain-text intent into functional shell scripts, command-line arguments, or PowerShell instructions. The C2 infrastructure then transmits these dynamically generated scripts back to the active memory-resident implant for immediate execution. While this setup suggests the threat group leverages automated AI tooling to lower the technical barrier of entry, it creates a unique and highly visible forensic footprint: outgoing connections from critical administrative servers to commercial LLM endpoints.

Surgical Harvesting and Lateral Propagation

The framework functions as an all-in-one execution suite. Once active, it deploys dedicated submodules to harvest sensitive credentials, establish lateral pathways, and prepare the host environment for complete domain compromise:

1. Broad Credential Extraction: The malware harvests stored passwords, cookies, session tokens, and browsing history from Chromium-based browsers and Mozilla Firefox. It utilizes the Windows DPAPI function CryptUnprotectData to extract secrets directly.
2. Cryptocurrency Wallet Theft: It searches default directory paths to siphon private data from wallets, including MetaMask, Phantom, Coinbase Wallet, Exodus, Electrum, Atomic Wallet, Ledger Live, and Bitcoin Core.
3. Infrastructure Access Collection: It
