Router backdoor vulnerabilities have endless hidden dangers and it is urgent to strengthen security protection
|
Last weekend, the "2013 China Internet Network Security Situation Overview" released by the National Internet Emergency Center (CNCERT) showed that router products of many well-known manufacturers, including Cisco and D-Link, have backdoors, which are easily controlled by hackers and endanger online security. Home routers have become a disaster area for network security . With the popularization of various smart devices, the use of wireless networks has become an important part of people's daily lives, and routers have gradually become key devices for building home wireless networks. As the hub of the home network environment, the security of routers is extremely fragile. The National Internet Emergency Center found that many mainstream router products on the market have backdoors and vulnerabilities. Using the code vulnerabilities left behind at the router software level, PCs, smart phones, TV boxes and other devices that are connected to routers for a long time can be easily controlled by criminals through the router channel to steal users' Weibo, QQ and other Internet accounts. The more serious risk is that if the router's DNS is maliciously tampered by hackers, when users enter the online banking and other network payment addresses to access, they may actually open a fake phishing website, and the online banking account password will be stolen by hackers, causing direct property and economic losses to users. Security experts put forward suggestions for safe use of routers. Faced with the security issues of routers being put on the table, 360, a domestic network security manufacturer, recently held a media communication meeting on this issue, and analyzed in detail the security risks that router backdoor vulnerabilities may cause to home networks. At the meeting, 360 security experts demonstrated on-site how to use backdoor vulnerabilities to invade routers, tamper with DNS addresses and other related network settings, control and hijack users' Internet information, and other operations. Security experts emphasized that adopting more secure encryption settings for routers is the most direct and effective security measure that is also the most easily neglected by ordinary users. Experts suggest that modifying the default management password of the router and encrypting the router with a strong password that combines uppercase and lowercase letters, numbers, and symbols is a security operation that ordinary users should perform before using the router to surf the Internet. In addition to strengthening the security level of password settings, Wi-Fi is encrypted with WPA/WPA2 and the WPS/QSS function of the router is turned off, which can further prevent Wi-Fi from being used by others to jeopardize the security of the entire home network. In addition, like other digital products, router manufacturers will also repair some invisible vulnerabilities through "firmware upgrades" for flaws and defects in software design. But in fact, due to the complexity of router settings, ordinary users often do not know how to use "firmware upgrade" and other methods, which also gives criminals an opportunity to take advantage of it to a large extent. 360 first launched four major measures to eliminate router backdoor vulnerabilities . The security situation of routers in the future is not optimistic. As 360, which currently provides Internet security services to more than 400 million Chinese Internet users, has pioneered the four major measures of "checking vulnerabilities, patching, detecting weak passwords, and repairing DNS" in 360 Security Guard to protect home routers. In the "Home Network Management" of 360 Security Guard, users can effectively detect and set up security for routers in a more intuitive and easy-to-understand way. Its specially added "firmware upgrade" function helps users automatically detect and repair router backdoor vulnerabilities, and anyone can operate it easily. Therefore, regularly using 360 Security Guard's "Home Network Management" to detect and repair routers can also greatly reduce the risk of routers being hijacked by hackers. In addition to being able to obtain the security "firmware upgrade" provided by router manufacturers in a timely manner, users can also control the connection and data modification of other devices with the router at the first time, protecting the router from third-party intrusion from the source. At present, 360 SafeGuard, as the first security protection software in China that covers router security, has taken the lead in fully supporting TP-Link brand routers, which have the largest number of users in China, and all router users can make further security settings for the routers in "Home Network Management". The rapid popularization of mobile smart terminals has extended the battlefield of network security to the router field in 2014, and "patching" the security of routers will become another important function of mainstream security software in the future.
