The Rise of DeepLoad: AI-Assisted Malware Exploits ClickFix and WMI for Stealthy Credential Theft

The Attack Vector: ClickFix Social Engineering

The infection begins with the ClickFix lure, a social engineering tactic that has surged in popularity throughout late 2025 and early 2026. Users are typically directed to a compromised website or a fake "fix-it" page (often appearing as a browser error or a document loading failure). The page provides a "Fix" button that, when clicked, copies a malicious command to the user’s clipboard and instructs them to paste it into the Windows Run (Win+R) dialog or a PowerShell terminal.

This "living-off-the-land" approach allows the initial stage to bypass browser security filters, as the user is the one manually executing the command that triggers the mshta.exe or PowerShell-based download of the DeepLoad stager.

AI-Assisted Obfuscation and Technical Sophistication

One of the most striking features of DeepLoad is its use of AI to generate an "obfuscation layer" designed to overwhelm static analysis tools. Researchers found that the loader’s code is padded with thousands of lines of meaningless but syntactically correct variable assignments and "junk" logic.

• Dynamic Compilation: DeepLoad uses the Add-Type cmdlet in PowerShell to compile randomized temporary DLLs in memory, ensuring that no consistent file signature exists for antivirus software to flag.
• In-Memory APC Injection: To avoid detection by Endpoint Detection and Response (EDR) tools, DeepLoad employs Asynchronous Procedure Call (APC) injection. It hides its malicious threads inside legitimate Windows processes—most notably LockAppHost.exe (the Windows Lock Screen process)—which is rarely scrutinized by security scanners.

Stealthy Persistence and WMI Reinfection

DeepLoad is not easily removed by standard "reboot and scan" workflows. It utilizes Windows Management Instrumentation (WMI) event subscriptions to establish a persistent foothold. If the primary malware process is killed or the system is cleaned, the WMI trigger—often set for a three-day delay—will automatically re-download and re-infect the host.

Furthermore, the malware is equipped with removable-media propagation capabilities. It monitors for connected USB drives and copies its payload into hidden folders, turning every infected workstation into a potential vector for internal lateral movement within a corporate network.

The Secondary Threat: Kiss Loader and Venom RAT

During the analysis of DeepLoad infrastructure, researchers identified a parallel campaign distributing Kiss Loader. While DeepLoad focuses on immediate credential theft, Kiss Loader serves as a staging platform for more destructive payloads, specifically the Venom RAT (a variant of AsyncRAT). This allows attackers to transition from simple data theft to full remote control and potential ransomware deployment.

The emergence of AI-obfuscated loaders like DeepLoad has shifted the metrics of the threat landscape:

Conclusion and Recommendations

DeepLoad represents a "perfect storm" of modern cyber-attack techniques: user-driven execution, AI-driven evasion, and system-level persistence. Organizations are advised to move beyond static file-based scanning and prioritize behavioral monitoring of WMI subscriptions and PowerShell execution. Disabling the Windows Run dialog for non-administrative users and implementing PowerShell Script Block Logging are critical steps in mitigating this threat.
