How To Detect Video Injection for KYC
For many KYC (Know Your Customer) vendors, video stream injection is the “final boss” of fraud. It’s the process of bypassing a smartphone’s physical camera sensor to feed pre-recorded or AI-generated deepfakes directly into the application’s media pipeline.
If successful, an attacker can register thousands of fraudulent accounts using stolen identities without ever showing their real face.
The good news? Most common injection tools rely on a compromised system state that Talsec RASP for Android and iOS already detects.
How Is Video Injected
Attackers typically use three main vectors:
- Hooking: Using LSPosed or VCAM modules to intercept Camera API calls and swap the live feed for a file like virtual.mp4.
- Emulators: Running the app in BlueStacks or Nox and using OBS VirtualCam to map a PC video feed as the “phone camera”.
- Automation: Using the Appium framework to script the entire KYC process, often utilizing plugins that instrument the app to inject images.
The Solution: Talsec’s Defensive Mapping
Because these tools require specific “illegal” environments to function, Talsec’s core features act as a multi-layered filter that stops the injection before the camera even opens.
Developer Pro-Tip
To maximize your KYC security, ensure you are utilizing Talsec’s full suite rather than just one module. By closing the door on Root, Hooks, Emulators, and Automation, you effectively neutralize majority of software-based video injection tools used in the wild today without needing complex video analysis processing pipelines.
