• Can Mikatech break ics not listed on this site ?

  Different chip manufacturers have different part numbers, but the inner core of the chip can be make with same technology, it would be quite impossible to list all the part numbers where our technology can apply such as MYSON, STK, FEELING, ANALOG, FUJITSU, NOVATEK, LG/HYNDAI.
  
  Also by the advancing of the technology, everyday we gain more and more experience and develope new methods for reverse engineering for different Intergated Circuit parts. Full list of Integrated Circuit part numbers which is within our scope of capability is always getting bigger, please contact us to find out.

• Voltage Glitching and Fault Injection for MCU Exploitation

  Voltage glitching has emerged as one of the most effective techniques for compromising the security of modern microcontrollers, enabling attackers to bypass authentication checks, extract secret keys, and dump protected flash memory. The fundamental principle behind voltage fault injection is deceptively simple: by introducing a brief, precisely-timed disruption into a microcontroller's power supply, an attacker can induce the device to execute instructions incorrectly or skip critical security checks altogether. This manipulation of the MCU's operational state can occur during boot, during cryptographic operations, or at any point where the device performs security-sensitive functions. The ChipWhisperer platform has become the de facto standard for voltage glitching attacks, providing researchers and security professionals with a versatile toolkit for fault injection experimentation. Building on this foundation, tools like the RP2040-based Interactive Glitcher have further lowered the barrier to entry, offering 5-nanosecond resolution timing and precise control over glitch parameters at a fraction of the cost of professional equipment. These developments have made voltage glitching accessible to a broader community of hardware hackers and security researchers, accelerating the discovery of vulnerabilities in commercial microcontroller products. The STM32 microcontroller family has been a particularly frequent target for glitching attacks, with researchers demonstrating successful bypass of read-out protection across multiple generations of devices. Recent work has refined these techniques into reliable, repeatable processes capable of extracting protected flash memory from STM32F2 and STM32F4 devices with near-perfect success rates. The practical implications of this research extend beyond academic interest—cryptocurrency hardware wallets such as Trezor and KeepKey, which rely on STM32 microcontrollers for security, have been successfully compromised using these fault injection methods. Voltage glitching is not limited to STM32 devices, however. Researchers have successfully applied fault injection techniques to bypass debug password protection on Renesas RH850 automotive microcontrollers, demonstrating that even safety-critical systems are vulnerable. Similarly, GigaDevice GD32 microcontrollers have been shown susceptible to both fault injection and invasive attacks that bypass read-out protection mechanisms. The breadth of affected devices underscores a fundamental challenge: microcontroller security often relies on assumptions about the physical environment that simply do not hold when an attacker has unrestricted access to the hardware. As fault injection tools become more sophisticated and accessible, the pressure on MCU manufacturers to implement robust countermeasures will only intensify.
