A new ClickFix campaign targets Windows users with a NodeJS-based infostealer delivered via malicious MSI installers. This highly adaptable remote access Trojan minimizes forensic footprints through dynamic capability loading, with core stealing modules and communication protocols delivered in-memory only after C2 connection. The malware routes gRPC streaming traffic over Tor network for persistent, masked bidirectional channels. An operational security failure exposed server-side admin panel protocol definitions, revealing a malware-as-a-service backend designed to manage multiple operators and automate cryptocurrency asset tracking. The modular architecture delivers malicious logic dynamically as strings executed in-memory, bypassing static signature detection while supporting full RAT functionality including shell command execution and wallet tracking.

A modular espionage framework targeting entities in Israel has evolved to incorporate sophisticated command-and-control capabilities. The framework employs DNS A-record responses to dynamically select between direct HTTPS connections and a Google Apps Script relay for each transaction, enabling operators to rotate communication channels and deployment identifiers. The communication module uses DNS infrastructure to validate and update Google Apps Script deployment IDs, while XOR encoding obfuscates command-and-control traffic. An inter-component broker coordinates framework DLL components, enabling runtime upgrades without system restarts. The infrastructure leveraged a previously expired Israeli domain, now repurposed with custom authoritative DNS servers, alongside legitimate Google services to blend malicious traffic with normal network activity.

Vanta Stealer is a Python-based information stealer utilizing PyArmor protection and PyInstaller packaging to complicate defensive analysis. The malware systematically harvests credentials from Chromium-based browsers, communication platforms like Discord and Telegram, gaming applications including Steam, Riot Games, Roblox and Minecraft, cryptocurrency wallets, Mullvad VPN configurations, and sensitive documents. It performs token enrichment by validating stolen Discord credentials against the API to retrieve account details, billing information, Nitro status, and server privileges. The modular architecture downloads dedicated browser extraction utilities at runtime, maintains independence between collection modules, and generates structured inventory reports before consolidating harvested data into ZIP archives. Exfiltration occurs via HTTP POST to attacker-controlled infrastructure with victim metadata. Distribution likely occurs through social engineering campaigns involving phishing emails, trojanized...
