Unpacking the StealC V2 Malware Campaign
Tactics and Distribution Methods
The StealC V2 malware campaign represents a cunning exploitation of Blender 3D project files, specifically targeting users through platforms like CGTrader, a popular marketplace for 3D assets. Attackers distribute tampered .blend files disguised as legitimate content, capitalizing on the trust users place in such platforms. These files, when downloaded and opened, become gateways for malicious activity, exploiting unsuspecting creators and hobbyists.
A critical component of this campaign is Blender’s Auto Run feature, which automatically executes embedded Python scripts upon opening a file. Cybercriminals embed malicious code within these scripts, enabling the malware to initiate an infection chain without any user interaction beyond the initial file access. This method ensures a stealthy entry point, often bypassing initial suspicion or scrutiny from victims.
The distribution strategy highlights a broader trend of leveraging legitimate marketplaces as conduits for malware. By hiding in plain sight among countless genuine assets, attackers maximize their reach, preying on the inherent trust within creative communities. This tactic poses a significant challenge for platform operators tasked with policing content while maintaining an open, user-friendly environment.
Technical Breakdown of the Infection Process
At the heart of the StealC V2 campaign lies a multistage infection process, beginning with a manipulated Rig_Ui.py script embedded in the .blend file. This script serves as the initial trigger, reaching out to remote domains hosted on workers.dev to retrieve a loader. The loader then facilitates the download of additional malicious components, setting the stage for deeper system compromise.
Subsequent stages involve the execution of PowerShell scripts and the deployment of ZIP archives containing Python-based stealers, which are extracted into the Windows temp directory. Persistence is achieved through LNK files, ensuring the malware remains active even after system reboots. Communication with command-and-control (C2) servers occurs via Pyramid infrastructure, a framework often associated with sophisticated threat actors, enabling data exfiltration and further instructions.
This intricate infection chain exemplifies the attackers’ focus on stealth and efficiency, minimizing detection by operating in the background. Each component is designed to blend seamlessly with legitimate system processes, making manual identification incredibly difficult without specialized tools. The technical sophistication of this campaign reflects a deliberate effort to exploit the nuances of Blender’s functionality for malicious gain.
Challenges in Detecting and Mitigating Malware in Blender Files
The deceptive nature of malicious .blend files poses a significant hurdle for cybersecurity defenses, as these files appear benign and often execute their payloads without overt signs of compromise. Many users, unaware of the risks, fail to scrutinize downloaded assets, especially when sourced from reputable platforms. This inherent trust, combined with background execution tactics, allows malware to operate undetected for extended periods.
Beyond individual user behavior, the open-source ecosystem surrounding software like Blender presents systemic challenges. The collaborative, transparent nature of such platforms, while a strength for innovation, also creates vulnerabilities that attackers exploit with ease. Traditional security tools, often designed for more conventional threats, struggle to adapt to these novel attack vectors, leaving gaps in protection.
Addressing these issues requires a paradigm shift in how threats within creative software are approached. Standard antivirus solutions may not flag embedded scripts or recognize the malicious intent behind seemingly harmless files. As a result, both users and security vendors must prioritize education and develop specialized detection mechanisms to counter the unique risks posed by malware in 3D modeling environments.
Evolving Capabilities and Accessibility of StealC V2
StealC V2 has undergone significant enhancements since its promotion on underground forums earlier this year, expanding its data theft capabilities to an unprecedented scope.

This broad attack surface ensures that virtually no digital asset or credential is safe from its reach.
What makes this threat even more concerning is its affordability, priced at just $200 per month or $800 for a six-month subscription. Such low costs democratize access to advanced cyber tools, enabling even low-tier threat actors with minimal technical expertise to launch sophisticated attacks. This accessibility fuels a proliferation of campaigns, amplifying the overall risk to individuals and organizations alike.
The implications of this trend extend beyond immediate financial or data loss, pointing to a future where cybercrime becomes increasingly pervasive. As tools like StealC V2 become commonplace in underground markets, the barrier to entry for malicious activities continues to lower, necessitating a reevaluation of how cybersecurity resources are allocated to combat both high-end and opportunistic attackers.
Defensive Innovations and Industry Response
In response to the StealC V2 campaign, cybersecurity firms have begun deploying cutting-edge strategies, with Morphisec leading the charge through a deception-based protection platform.
