Now in China's wireless LAN security situation

　An ID and password were leaked from the Rogytec wireless LAN router, and a proxy server for Chinese users was abused by cyber attacks on Japan.In China, where PC Internet is first widespread and smartphones have become widespread, wireless LAN routers are owned by many Internet users.In China, wireless LANs have been hacked and abused.The problem was reported in a special feature on the influential national television "CCTV".

　According to the analysis of the National Beloca Safety Leaky Leakage (CNVD), there are backdoor products in manufacturers such as Cisco, D-Link, LinkSys, NetGear, and Tenda, which are seen in China, and in China.It's not just a logitech problem, but a problem that can occur with all wireless LAN routers.Japanese users do not think of the story beyond the sea, but want to update the wireless LAN router's firmware to the latest.

　According to a security report on the router announced by the 360 Conventional Network Safety Center this summer, as of the end of June 2014, more than 1,000 models and about 100 million wireless LAN routers were running.68.5 % home, 12.7 % is school dormitory, 9.3 % are used at work.Regarding the number of wireless LAN routers users 1 person is 1.There are only 6 %, and "2-3 people" are 55.8 %, "4-5 people" 32.7 %, "6-8 people" 7.It is 3 %.

　In other words, it is extremely rare for "people living alone" and "younger generation in the family" occupy a wireless LAN router alone and use a PC or smartphone.。So, not only the youth generation, but also the elderly people and children will use wireless LAN routers, 5 under 18 years old..6 %, 46 years old or older 1.There are only 3 %, and the users are concentrated on generations in the meantime.Chinese who do not hesitate to call people at home often call colleagues and old friends, but such visitors should interpret them as "one of multiple people using wireless LAN routers at home."

　Before 2008, when smartphones were not yet widespread, I remember seeing a wireless LAN router that has not set a password.Now that it has become widespread, many wireless LAN routers are passwords because the security awareness is improved and the product itself has a default password.According to the report, many of the 100 million wireless LAN routers that operate use the WPA/WPA2 PSK password, 800,000 units, and 3.3 million units using the WEP method.It's just.

　However, despite the password, the wireless LAN router, which is a lot of wireless LAN routers, has set a classic password "12345678 (1 to 8)" and "8888888 (8)".There is.In addition, the initial password of routers such as "Admin" and "Root" is often used.Nevertheless, recently, in the third quarter of 2013, it has been raised in each media to raise security issues related to routers.."Easy -to -understand password" was adopted for 6 % routers, but 24 in the second quarter of 2014.It has been reduced to 3 % and has improved considerably.

　61 of the vulnerable password of wireless LAN routers.A 1 % router has a vulnerabilities of "CSRF (CROSS-SITE Request Forgeries. Request forced)" known for the "My Town-chan" turmoil.It is also said that 750,000 wireless LAN routers are hijacking DNS.The main cause is that it is affected as a result of accessing dangerous sites, but it is not only a porn advertisement in Japan in China, but also online shopping sites, links based on links and QR codes set up by the store to make money.There are things, and there are many traps set.

　In addition, it is known that China has a particularly higher JAILBREAK rate of iOS equipment and Android devices compared to other countries.For this reason, there are many projects in which personal information such as photos and short mail in smartphones and tablets, through wireless LANs, are stolen.
