The US advanced defense server reported on August 28: Thanks to the Internet of Things technology, all kinds of gadgets, household appliances and even cars have become more and more smart, but apparently, they are not smart enough to resist network attacks.
A few days ago, a white hat hacker dedicated to network security research found a security vulnerability in the Samsung Smart Refrigerator (model: RF28HMELBSR), through which the hacker could intercept the communication content between the refrigerator and Google Calendar, thereby stealing Google accounts. This Samsung smart refrigerator is designed with a touch screen on the front door and built-in WIFI function, which can connect to the Internet to obtain real-time weather forecast, play network video, music, and even make network calls, focusing on the concept of kitchen multimedia.
Internet of Things security needs to be improved
In fact, not only Samsung, but also many IoT devices in the current market have common security vulnerabilities, which need to be improved and repaired by manufacturers. At the recent DEF CON hacker conference held in Las Vegas, the United States, security researchers and white hat hackers found 25 Internet of Things products with loopholes, including kitchen scales, coffee machines, wireless cameras, smart door locks, smart Hubs, and so on.
Generally speaking, as long as hackers can crack the WIFI network and enter the home LAN environment, they can find vulnerable IoT products and achieve intrusion, attack or theft of information. Previously, the case of hackers invading baby monitors and abusing babies has caused a great stir. More and more users are worried that the smart devices in their homes will become the entrance for hackers to invade.
As for how to improve this problem, the lack of unified standards in the field of Internet of Things is a major obstacle. Manufacturers are committed to developing their own standards, and it is inevitable to ignore some software vulnerabilities. Of course, many security companies have begun to pay more attention to this problem. For example, Symantec has launched embedded security solutions; And the intelligent router added with the product management function of the Internet of Things has gradually gained market attention. For ordinary users, the most basic preventive measure is to ensure that the wireless router uses WAP password authentication and change the default password of the management account.
