è¹­ NICs resurrected underground peddling: said 70% reduction in radiation prices soared

"My home-installed broadband network can be faster than before. Downloading movies is awkward. How can you open a web page for half a day before it can be opened?" Miss Cui, the resident, has been annoyed by the speed of computers recently. After "diagnosis", it was discovered that the original home network had been "deaf" by others.

Computer experts said that the “uninvited guest” who stole the wireless network of Miss Cui’s home uses a device called a “network card”. The reporter learned yesterday from several electronic markets such as Zhongguancun Dinghao and Hailong that the “蹭 network card” has disappeared in the open market, but this product has not disappeared, but it has been transferred to underground channels through the Internet, mobile phone messages and other means. To sell.

è¹­ network card with a "new generation"?

"Double-net tools are illegal, and we are not allowed to sell them here." At the Zhongguancun Hailong Electronics City, several stall owners shook their heads as soon as they heard someone's inquiries about the "card card." A stall owner said that he had indeed sold such products here, and the price was generally between 50 and 100 yuan.

The stall owner also stated that one of the reasons why the “card card” is delisted is that the product is harmful to the user and thus gradually “lose favor”. "It is said that the radiation is very large and there are not many people who bought it later."

However, the reporter found that “new generation” network tools, which have improved the safety performance of products and reduced the radiation level, have come back. They have launched “underground” advertisements by sending spam and SMS messages. One of the products received by the reporter, called “Kingwang”, said that the upgraded new generation of products could reduce radiation by 70%, and emit even lower radiation than mobile phones. The price is RMB 268. Compared to the "old generation" products, their value has soared.

The use of network cards to harm people has been introduced, according to industry sources, the network users are the target of the use of wireless routers to access the Internet users, and for the use of wired routing and public WiFi service, there is nothing to do. But recently, as Apple iPads, iPhones and other products that require wireless network access have become hot, more and more consumers are starting to configure wireless routers at home, which has also made some Internet users who are looking for wireless networks.

"'蹭 network card' is actually a super power wireless network card, power is generally at least 10 times the average wireless network card on the market to receive the signal of the neighbors, the better the product's ability to accept it means more radiation." Telecommunications Engineer Xu Yang said that what the seller called “good reception and low radiation” was purely a flicker.

Set up complex passwords to prevent bedding IT industry experts have warned that being "deep network" not only affects their own network speed, but more serious is that after the network "invasion", the user's shared folders, shared hard drives are completely exposed Prior to the aspect, the possibility of privacy leaking or being implanted with a Trojan horse has greatly increased.

How can we prevent being "swallowed"? Professionals said that first of all, the wireless router at home must set a password, and do not use simple letters or numbers, preferably a combination of more than 8 letters plus numbers. In addition, when the wireless router is not in use, it is better to shut down. On the one hand, it saves energy, and on the other hand it also reduces the chance of using a tool to crack the password for a long time.
