A coordinated action led by Microsoft's Digital Crimes Unit, with participation from Bitsight and other partners, has successfully dismantled the operational capabilities of Lumma Stealer (LummaC2), a prominent information stealer operating since late 2022. The operation involved seizing over 1,000 domains and shutting down more than 90 Telegram channels and Steam profiles associated with the malware's infrastructure. LummaC2, which gained popularity after the takedown of Redline and Meta stealers, targeted Windows systems to extract sensitive data from various applications. The malware employed a complex, multi-tiered command and control infrastructure, using multiple domains, Steam profiles, and Telegram channels for resilience. This disruptive action is expected to significantly impact the threat landscape and hinder criminal activities in the malware scene.
StealC V2, introduced in March 2025, is an enhanced version of the popular information stealer and malware downloader. Key updates include a streamlined JSON-based C2 communication protocol with RC4 encryption, expanded payload delivery options (MSI packages and PowerShell scripts), and a redesigned control panel with an integrated builder. New features comprise multi-monitor screenshot capture, a unified file grabber, and server-side brute-forcing for credentials. The malware now supports customizable payload delivery rules based on geolocation, hardware IDs, and installed software. Technical analysis reveals improvements in obfuscation, API resolution, and configuration encryption. StealC V2 is actively developed and frequently used in conjunction with other malware families like Amadey.
The Hannibal Stealer is a sophisticated information-stealing malware, rebranded from Sharp and TX stealers. Developed in C#, it targets Chromium and Gecko-based browsers, extracting sensitive data while bypassing Chrome Cookie V20 protection. Its capabilities extend to cryptocurrency wallets, FTP clients, VPN credentials, and various system information. The malware includes a crypto clipper module and is controlled via a dedicated C2 panel. Sold on dark web forums, it employs geofencing, domain-matching, and comprehensive system profiling. The threat actor behind Hannibal Stealer has been linked to previous iterations, indicating minimal innovation beyond rebranding and updated communication methods. Active Telegram channels and control panels suggest ongoing operations and infrastructure maintenance.
SvcStealer 2025 is a novel information stealer delivered through spear phishing email attachments. It harvests sensitive data including machine information, installed software, user credentials, cryptocurrency wallets, and browser data. The malware creates a unique folder, terminates specific processes, and collects data from various sources. It compresses the gathered information, establishes a connection with a C2 server, and uploads the data. The malware can also capture screenshots and potentially download additional payloads. It employs evasion techniques by deleting traces and ensuring only one instance runs on the victim's machine. The threat actors behind SvcStealer could potentially act as initial access brokers, selling the gathered information on underground forums and criminal marketplaces.
