Can you "change at will" with money?

　　Changing the IP address on your behalf hides the risk of privacy leakage

　　Our reporter Yuan Lu

　　Recently, Internet platforms including Weibo, WeChat, Zhihu, and Xiaohongshu have successively launched the function of displaying IP territories. Domestic users are displayed in provinces or regions, and foreign users are displayed in countries.

Many online "big Vs" have exposed their traces of pretending to be abroad. Most of the homepage's IP territories are in China, and netizens have ridiculed them for "revealing the stuff".

　　After the Internet celebrity IP address "overturned", some people tried to use illegal means to change the real IP attribution on the Internet, which also prompted the "black business" of paid IP agents such as daily rent, monthly subscription, and annual subscription.

Network security experts said that changing the IP address does not really modify the online identity addresses of mobile phones, computers, etc., but hides the risks of privacy leakage and stolen financial accounts.

　　You can change the IP monthly for 15 yuan

　　Yesterday, the reporter easily found IP proxy services on multiple e-commerce platforms through keywords such as "IP territorial" and "IP proxy".

These merchants stated that they can support computers, mobile phones, simulators and other equipment to change IP, and charge according to the annual, monthly, daily rent and other modes.

Among them, the reporter found in a Taobao online store that the static proxy IP service only costs 15 yuan per month.

　　"Which APP do you want to change? What mobile phone system?" After a brief inquiry, the store showed a website address to the reporter.

After the reporter paid and provided the ID number for real-name registration, he saw in the back-end system where the address was redirected, the "node purchase" page showed that hundreds of APPs supported to change the IP location, including Douyin, Douban, Weibo, WeChat, Xiaobian, etc. Red Book, Zhihu, Xianyu, etc.

　　"After you connect to the new IP address, log in to an APP again, and find a post to comment on. After the comment is completed, the IP will be modified successfully." The seller said.

　　Taking Sina Weibo as an example, the reporter selected "Guangdong Guangzhou" from multiple IP nodes such as Kunming in Yunnan, Changsha in Hunan, Qingdao in Shandong and other IP nodes. There is no change, but when the account is used to post news or comments, the IP territorial becomes the disguised Guangzhou.

　　Another store seller told reporters that he can provide static IP or dynamic IP to change the IP address of a mobile phone or computer, and supports most APPs, which are relatively stable. The addresses that can be changed cover almost all major provinces and cities in China and Autonomous Region, "I can provide you with a half-hour free test, and then pay if you find it useful."

　　Changing the IP just added a "speaker"

　　IP is the abbreviation of Internet Protocol (Internet Protocol). An IP address is an address unique to the Internet Protocol, and is the only identity address required to surf the Internet.

　　Pei Zhiyong, director of Qi'anxin Industry Security Research Center, told reporters that the so-called IP change does not really modify the Internet IP of the mobile phone, but the Internet IP of the mobile phone seen by the information receiver.

"The IP of the mobile phone itself is dynamically allocated by the operator to each mobile phone or computer. If this IP is really changed, the operator will not be able to identify your device and will not be able to access the Internet."

　　Pei Zhiyong said that the method of using "proxy" to change the IP is to let a certain mobile phone first send the information to a certain network proxy server, and then send the information to the recipient as the proxy server.

Where the proxy server is, the displayed IP address is there.

Since the receiver only knows that the information is sent through a proxy server IP, but does not know who sent the information to the server, in the end, in the eyes of the receiver or the platform, the information is sent from the IP of the proxy server. of.

　　"For example, no matter who comes to you, you have to let your neighbor, Aunt Zhang, pass the message. Then the outside world only knows where to find Aunt Zhang, but not where to find you. On the Internet, Aunt Zhang is your agent. Server." Pei Zhiyong said.

　　It should be noted that the reporter learned from the investigation that it is not difficult for practitioners to identify whether the IP has been modified.

Whether it is an Internet platform or a specific APP, as long as you identify which IPs are proxy servers, you can "follow the trails" and quickly ban the accounts behind the proxy IPs.

Once suspected of cybercrime, public security and operators can quickly find the source of information.

　　Risk surges after IP territorial change

　　Regarding the online IP territorial function, many platforms stated that the original intention was to reduce bad behaviors such as impersonating the parties to hot events, malicious rumors, and swindling traffic.

However, some netizens expressed concern that they would reveal their privacy after opening their IP territories, and then wanted to seek to modify their IP addresses.

However, does modifying IP really protect privacy?

During the visit, multiple IP proxy systems required reporters to provide their real names and ID numbers during the registration process.

　　"The purpose of modifying the IP is to hide the source of the information." Pei Zhiyong said that from a practical point of view, it is difficult to obtain legal protection for the purchase and use of software or services with modified IP. Once consumers have disputes with merchants, it is often difficult to defend rights.

　　"Safe Beijing" also reminded on Weibo recently that for individuals, after using a black proxy IP, it is easier for hackers and viruses to invade personal hosts and obtain personal information and data than to eat.

　　He Yanzhe, deputy director of the Evaluation Laboratory of the Cyber ​​Security Research Center of the China Electronics Standardization Institute, told reporters that the display of IP territorial information on social platforms is of great significance. Clean up the network environment.

"We must be alert to the risks of IP proxies. Unreliable IP proxies are very likely to be involved in the 'black and gray industry chain', and there will be problems such as fraud and theft of accounts, theft of financial accounts, and privacy leakage."

　　To this end, He Yanzhe also called on relevant departments to strengthen supervision, to issue regulatory rules for paid IP agents as soon as possible, to guard against variants of paid IP agents, and to prevent IP agent business behaviors only by means of keyword blocking. targeted measures.
