GigaVulnerability: GD32 Security Protection bypass
Alexey Kovrizhnykh
Security Researcher, Positive Technologies
When developing hardware solutions based on microcontrollers, manufacturers want to protect their firmware from falling into the wrong hands. To do this, most microcontrollers implement readout protection technologies. Do they protect well?
The first part of the talk will briefly describe the existing attacks on these technologies. The second part will be devoted to our research on the security protection technology of GD32 microcontrollers (GigaDevice) and the vulnerabilities found that allow obtaining the contents of the memory despite the protection enabled
