Key Takeaways
- DeepLoad is a fileless loader delivered via ClickFix, tricking victims into pasting a malicious PowerShell command into Windows Run or a terminal.
- The payload is injected into trusted Windows processes (such as LockAppHost.exe) via asynchronous procedure calls (APC) to evade detection.
- Credential theft runs on two tracks: filemanager.exe harvests saved browser passwords, while a malicious browser extension captures credentials in real time.
- DeepLoad spreads via USB drives by dropping over 40 shortcut (.lnk) files disguised as common installers, each capable of re-triggering the full infection chain.
- Picus Threat Library includes dedicated DeepLoad simulation threats (IDs 56483 and 37782) across email and network infiltration modules to validate security controls.
DeepLoad, first observed in March 2026, is a fileless loader observed in enterprise compromises. Delivery of the malware happens through ClickFix, a social engineering technique where the user is tricked into pasting an attacker-supplied command into Windows Run or a terminal under the guise of fixing a fake browser error.
