Just past the 3 15 party, by professional network security engineers as hackers, disguised as the party studios free wifi,500 more than the audience on the spot, and unknowingly through the hacker's WiFi hotspot in the circle of friends hair Photos- The photos that the audience had just taken and the phone-bound email password were all on the big screen--and I'm sure everyone remembers it.

Today, routers become a lot of families, and even the necessary equipment for white-collar travel, but the DNS hijacking, theft of information, phishing and other security incidents frequently, so that the router has become an ambush in your side of the network security "landmines."

Low-price security risks

Security is the biggest threat to consumer-level router products at present. 360 the data released by the Internet Security Center shows that domestic routers have about 100 million units, but the router security is serious, in which csrf vulnerabilities in the recognizable model/firmware version of the 40.14 million routers coverage of up to 90.2%, about 3.3 million users using WEP this earlier encryption method, These all make the router at a high-risk state.

"When the home is filled with associated devices such as thermostats, smoke detectors, faucets, locks and bulbs, the lack of defensive capabilities of routers can be a big problem," he said. Hackers could easily invade the center of a home network and do whatever they wanted on smart-home devices: Unlock the door-turn on the tap and flood the house-to send an alert to users who are attending important meetings. ”

Why does the router have so many threats to our internet seat belts? According to experts, the vulnerability itself can only be alleviated by the affected hardware vendors through firmware updates, and routers typically use inexpensive components and simple programming, which can be sold as long as they work properly.

At present, most home users only choose to use a cheaper WiFi router, due to low profit, most manufacturers ignore technology upgrades, many of the curing software generally exist problems such as technology lag. Compared with the computer, the router system software to play a new patch speed is slow, equipment manufacturers to the safety of the degree of attention is far less than the computer system vendors, therefore, the router security vulnerabilities are vulnerable to malicious software and hackers to use.

Confuse the concept of speculation to conceal weaknesses

Transmission speed and wireless router signal strength is an important indicator of the quality of the router, the market many home routers have a lot of relevant introduction, however, "full Netcom", "5GHz band 0 Interference", "wall" concept, you really understand?

"5GHz band 0 Interference" as an example, experts said that at this stage of the 5GHz band interference is indeed very little, mainly because the use of this band of equipment is not much. "If the new open band is supported by network equipment manufacturers, with wide bandwidth, low interference and smooth connection is guaranteed, but 0 interference is a bit exaggerated." ”

In addition, the farther the router distance, blocking or interference, the faster the speed of wireless data transmission, especially for the weak wall through the 5GHz signal, attenuation is even greater, the rate of transmission will be greatly reduced.

Is it really cool to "wear a wall"? From the extreme routing products that claim to have this function, only the 2.4GHZ signal setting option has the option of "wall through" mode, the principle of which is to enhance the signal by dynamically adjusting the transmit power. This approach also reduces signal fault tolerance and delays the signal. Therefore, "through the wall" may alleviate the home the signal dead end problem, but is apt to appear the webpage opening speed to be slow, the on-line video card and so on signal deterioration situation.

In addition, some 4G portable router manufacturers in order to create selling points, deliberately to "three netcom" and "total Netcom" the concept of confusion, but in fact, there is a difference between them. At present, "all Netcom" wireless router has five-mode 13-frequency and six-mode 15-frequency two types, as a result of the use of different chip schemes, so the six template than the five models to increase the support of Telecom 3G Network, in the 4G coverage is not good two or three-line city, five-mode products used up very disadvantage, six-mode and five-chip spreads on the price of 5 U.S. dollars.

"Virtual standard" moisture up to 70%

Reporter in the interview found that with the release of 4G licenses, 4G routers become a lot of white-collar like to carry out one of the time equipment. 4G routers, commonly known as portable WiFi, directly into the 4G SIM card, support for multiple wireless devices to access the portable router. It is understood that the current domestic large-scale electric business platform on nearly hundreds of models for sale, from dozens of yuan to hundreds of yuan, many brands, most of their alleged selling point is "full band", "Strong signal", "long endurance."

For users, routers value two points: speed and transmission distance. Reporters found that a number of 4G routers in the promotion of the emphasis on "wireless transmission rate up to 300Mbps", "theoretical coverage of 150 meters" and so on. But not really, according to telecommunications experts, wireless network is in the form of microwave transmission in the air, but this electromagnetic wave in the transmission process is very vulnerable to external interference will have attenuation, plus the volume limited, the antenna is small, but also to control calorific value, so the transmission power is limited, 300Mbps theory wireless transmission Speed 37.5MB /s, the actual only 8mb/s, "moisture" reached 70%.

From the transmission distance, 150 meters is completely the ideal laboratory data, the actual only reached 10 meters, and the middle can not have obstacles, distance increased, the speed of the decline of some large. In addition, some small brands of 4G wireless routers in order to attract people, often add mobile power and other functions, virtual standard is very common, media testing, a built-in 5600MAH battery 4G router products, the actual conversion rate is only 65%.

Secret

It only takes two hours to crack the WiFi password.

It is understood that the traditional router set up in the market is a single method, usually does not lead users to use complex passwords and higher levels of encryption. People in order to easily like the Internet password set easy to remember, for example, 6 birthday, the shorter the more regular password is cracked less difficult, crack the short password of pure numbers for hackers is not a difficult task.

In addition, pin vulnerability is a hacker often use one of the WiFi vulnerabilities, pin design is designed to allow two devices fast-free connection, the router's pin itself is very short and completely composed of numbers, hackers can only need two hours to successfully crack. More wonderful is that the pin can be converted through the device's MAC address, once you know the conversion method, cracking almost as simple as a middle school math problem.


Poor quality mostly lack of 3C certification

Experts pointed out: "Although the router has industry standards, but the implementation of the manufacturers are mixed." Recently, the Jilin Municipal Bureau of Industry and Commerce on the nominal Shanghai, Guangdong and other areas of production and sales of routers, mobile hard disk and liquid crystal display, such as electronic information products carried out a quality inspection, in the extraction of 17 samples of 2 groups of routers are judged unqualified, unqualified rate of 11.76%, the main problem is that radiation disturbance unqualified. "Radiation harassment of products exceeding the standard may cause peripheral devices, equipment or system can be reduced, interfering with other electronic products of normal work, and the human body caused a certain harm." ”

In addition, the market is currently emerging a number of 4G wireless routers lack of 3C certification, according to the relevant provisions, wireless routers must have 3C certification. The national Computer external equipment Quality Supervision and inspection center previously on the market 20 brands of wireless router detection, labeled as B-link, Volans, Edup, Utt Hayter, Wavlink and Totolink of the router, are missing or part of the lack of 3C certification signs.
