Let's discuss the security protection design of IoT smart devices [Copy link]

 As smart hardware enters people's lives, people's quality of life has gradually improved, and the concept of the Internet of Things has penetrated deeper into our lives. With the help of the Internet of Things, we can monitor everything in and outside the home. Have you ever thought about what would happen if the hardware devices around you were implanted with malicious code, just like in the movie? In fact, the case of counter-monitoring has really happened in reality, and it was said by a friend who does monitoring. Fortunately, he found that his monitoring system was attacked, so he never installed such a system in his home again. It has also been reported how the sweeping robot became a "spy". Hackers used vulnerabilities to disguise themselves as users to log in, and then remotely controlled the sweeping robot, and monitored the home environment in real time through the connection between the camera and the mobile phone. The security risks of home cameras include not only the public sale of IP, but also the spread and sale of cracking software in QQ groups. Do you think it's scary after reading this? Here is a mention of TI's msp430f149 chip Hook attack test. For msp430 chips, manufacturers generally burn out fuses when leaving the factory to prevent firmware extraction. But in fact, you only need to pay a few hundred RMB to repair the fuse of the msp430 chip and extract the firmware content. First, use the tool to dump the firmware content in TI-TXT format, then implant the opcode for Hook, and then complete the modification operation on the TI-TXT file. What kind of chips have you used to develop IoT (Internet of Things) devices? What kind of security protection design is generally used to attack these smart devices?
