The Invisible Guardian of Intelligent Connected Vehicles Firmware security detection and penetration

Mondo games Updated on 2024-02-06

In the new era of connected cars, the way we travel is being redefined. Not only do these vehicles boast high-tech features such as autonomous driving and remote control, but they can also seamlessly connect with the outside world via the internet. However, with the increase in intelligence, the safety of vehicles is also facing unprecedented challenges. In particular, the firmware of on-board electronic devices, as the cornerstone of the vehicle's intelligent system, is directly related to the safe operation of the entire vehicle.

The electronics firmware of the connected car is at the heart of the vehicle's operation, controlling everything from the engine management ECU to the infotainment system IVI. With the increasing complexity of vehicle functions, the security of the firmware becomes even more important. Security vulnerabilities in the firmware can lead to hacking of the vehicle, which can affect the normal operation of the vehicle and even endanger the lives of passengers. Therefore, safety testing and penetration testing of on-board electronic firmware has become a key link to ensure vehicle safety.

Firmware security detection is a proactive security measure designed to uncover potential security vulnerabilities by analyzing the firmware's structure and structure. This kind of detection usually includes static binary analysis, dynamic analysis, vulnerability detection, and other techniques. Static binary** analysis can help us understand the vulnerability logic of firmware, dynamic analysis can verify unknown vulnerabilities through methods such as symbolic execution, and vulnerability detection can identify known security vulnerabilities. With these approaches, we can mitigate security risks by identifying and fixing potential security issues before firmware is deployed.

Reverse analysis of automotive electronic device applications is a very important technical means in vulnerability mining and exploitation. However, C++ binary analysis (and disassembly) is a lot of work; If it is read and analyzed by humans, the workload is quite large. In addition to clearly pointing out the vulnerability address, the firmware security analysis platform has an automatic call stack analysis function, which can also show the call path generated by the vulnerability, making the vulnerability exploitation more traceable and making the vulnerability mining work very accurate and efficient.

Penetration testing simulates hacker attacks, takes advantage of the potential risks we find in firmware security analysis, and confirms them with real-world environments and devices. Penetration testing not only helps us understand the vulnerability of the system, but also provides real-world attack scenarios that help us better understand the tactics that attackers may adopt. This kind of testing typically includes steps such as information gathering, threat modeling, and real-world infiltration, and is designed to comprehensively assess the security of the system from the attacker's perspective.

In the practice of safety testing of intelligent networked vehicles, Chengdu Qiwu Technology provides a series of solutions. These solutions include not only the firmware security detection and penetration testing technologies mentioned above, but also a full range of services from project management to device management. The platform supports the analysis of firmware file system, firmware version evolution and security trend changes, as well as in-depth detection of sensitive information leakage, certificate security, configuration security, etc. in the firmware. These services not only help customers identify potential security problems in advance, but also provide detailed security reports and solutions to help customers establish a safe and reliable protection system.

The information security of intelligent networked vehicles is a long-term battle, and firmware detection is the front line in this battle. Through continuous technological innovation and practical exploration, the firmware security analysis platform of Qiwu Technology not only provides comprehensive testing services for the safety of intelligent networked vehicles, but also greatly improves the detection efficiency and reduces the cost through automation and intelligent means. The firmware detection platform will also become more intelligent and automated, providing a more solid security guarantee for intelligent travel.
