According to industry insiders, this is mainly because Wi-Fi has security vulnerabilities, earlier Wi-Fi security mechanisms, WEP/WPA, have been cracked, and upgraded WPA2 can also be cracked.
Wi-Fi encryption technology is often broken
The so-called "network anti-DDoS" refers to the use of a special device to crack the access restrictions of a specified wireless network in a region covered by a wireless router. That is to say, if others do not know, they will share their networks. This "special device" is the "ENI" or "ENI ".
Previously, Wi-Fi devices were even graded on the market, with the retail price ranging from 80 yuan to 280 yuan, which seriously threatened the security of Wi-Fi users, this makes Wi-Fi security problems attract more attention.
In this regard, some industry experts said that Wi-Fi security mechanisms have been being upgraded. Wi-Fi uses IEEE 802.11i as the standard for secure access. IEEE 802.11i includes three security mechanisms: WEP, WPA, and WPA2. In the early stage, WEP/WPA was used as a security mechanism, but it has been proved to have serious security vulnerabilities, at present, there are circulating methods on the Internet to crack the above Wi-Fi security mechanism.
WPA2 is an upgraded version of WPA. This year, the Wi-Fi Alliance released the latest industry security roadmap for Wi-Fi and announced that it will abandon WEP/WPA in all aspects, to promote the new security mechanism of WPA2, Wi-Fi products for enterprises and home users will gradually support WPA2. However, from the perspective of the industrialization and technical level of Wi-Fi network devices in China, in fact, WPA2 will soon be cracked. Otherwise, it is difficult for domestic Wi-Fi network devices to be popularized and widely used among users.
A few years ago, when the Wi-Fi Alliance released the patch version WPA for WEP with severe security vulnerabilities, it also declared that: WPA will meet the requirements of both manufacturers and consumers in the foreseeable future. But soon, WPA was cracked.
WPA2 Personal Edition is not secure
WPA2 has two editions: Personal Edition and Enterprise Edition. All users of the Personal Edition of the entire network share a password (pre-shared key or PSK for short). Each user of the Enterprise Edition has an identity credential, and the security factor of the individual edition is lower than that of the Enterprise Edition.
It is reported that some foreign senior underground hacker organizations have set up to G detailed WPA/WPA2 attack Table library, and even some basic perfect WPA-PSK Hash Tables has been publicly sold on hacking websites, you only need to pay about $120, there will be 8 containing WPA-PSK Hash Tables of the DVD Disc directly sent to the user through Fedex.
According to an earlier article, a wireless hacker organization named The Church of Wi-Fi has successfully established a huge WPA Table library in The past two years, and provides free download of its simplified WPA-PSK Hash Table version, which actually means cracking WPA and wpa2. Domestic Wi-Fi network adapters are likely to use these brute-force cracking techniques.
ADSL and 3G cannot intercept network
However, in any case, the use of the Wi-Fi network device is beneficial to the user, but it is a disaster for the victim, because the result is not only the network, but also information security issues. Even non-professional technical personnel can easily steal the user name and password of a Wi-Fi user's email address and intercept information such as MSN chats by using the "Wi-Fi network device, this also provides more opportunities for hackers with malicious intentions.
Since the cyber-bot incident was widely noticed last year, the phenomenon of Network-related litigation and network-related legislation has already spread across the north and south of the Yangtze River. During the "NPC and CPPCC" this year, Liu Hongyu, a member of the CPPCC, even submitted a proposal to crack down on network infringement such as "dang Wang" to the NPC and CPPCC.
However, some insiders said that from a technical point of view, it is difficult for telecom operators to get rid of ADSL fixed network broadband and 3G wireless broadband, which are related to the technology used.
