 How hard is it to permanently delete WeChat records? The expert suggested that the cell phone be smashed!


Visual China You may never have thought that the WeChat message you deleted by yourself can be restored with only 10 yuan. Last month, the Hefei municipal discipline Commission issued a message in its WeChat public number, in March this year, Anhui Chaohu Municipal Commission for Discipline Supervision and commission in the case, the use of science and technology from the conversation to extract a group of deleted WeChat chat records, to successfully complete the case detection. The news has caused many netizens to worry about their own information security. As the most commonly used social software in China, WeChat has always said that it will never store users chat messages. But many netizens still question why the deleted chats can still be restored. In April 29th, the official public number of WeChat, WeChat pie, explained, the message is that the extraction of deleted WeChat chat records is actually recovered from the storage system of the mobile device itself through forensic forensics. It sounds terrible. In the age of intelligent technology, it is more difficult to burn after reading on electronic devices. A security expert said that the information deleted on the phone was theoretically restored and could not be permanently deleted. Is it true? Of course not, but the methods are brutal and brutal. Many technical experts almost give the same answer: blister hammer - physically destroy equipment. Deleted WeChat chat record, a treasure 10 yuan can be restored. Search how to restore WeChat chat records, there will be many tutorials online, in a treasure, there are marked 10 yuan to more than 100 yuan of data recovery services. The experience video shown on the Internet shows that even a few years ago, chat records can be restored. The Beijing News reporter consulted a businessman on the need to restore information on the old phone, customer service said: with mobile phones connected to the computer, simple cooperation can be restored. The recovered information does not even need to consider the length of the deletion. After taking the 10 yuan data recovery service, the merchant sent a software package called the master of Apple recovery. In this mysterious software package, the software was opened and the recoverable information was included in the WeChat chat record, including the users address book, memorandum, photos, text messages, and so on. Cover all the privacy information in the phone. If you want to restore the deleted information, choose the corresponding icon, then wait for the result of the recovery quietly. Data recovery is just a saving measure, and the degree of data recovery is determined by multiple factors. If the information is not scanned, it is completely lost, a technical customer service explained. Reporters measured the resumption of WeChat chat records, waiting for three or four minutes, on the screen to jump out a number of deleted chat records. I looked at my friends ridicule two weeks ago, and my heart began to rise unconsciously. Think about it, your deep greeting to the young lady in the near night, the text message from a friends slots led by a friend, the website that should not be seen, can be restored to people at 10 dollars, and ask you to be afraid of fear. However, the software recovers only some of the chat records deleted, and fails to completely restore the deleted information. Customer service explains that this is because the database is covered. It seems that the data recovery software purchased by 10 yuan is still not strong enough. On a treasure, the most expensive data recovery service charges 5000 yuan, we have rich scientific recovery technology and operation experience. Help you to get back the important documents in the first time! Ask Wangwang to consult! Such slogans are redacted by sellers and put on the details page of the merchandise. Frankly, this kind of service can help you when you want to get back the information, and when the information doesnt want to be seen, it is likely to be killed. How did this be done A number of security experts told reporters that the resumption of WeChat chat records is theoretically possible. According to WeChats official statement, WeChat does not upload user chat messages to the cloud, and the chat record is actually stored on the phone. Image analysis technology security expert Pan Xiaobo analysis, WeChat chat record recovery may be similar to the file system recovery. The deletion of the file by the operating system is only a mark, and only the file index is deleted. Therefore, you can search the disk directly to find the content of the file and restore the deleted information. Sun Weibo, the safety technology director of the Ivy cloud, explained that the general deletion of the file is just marking the area of the document on the storage device. It has not been completely deleted. When the next file is written, it will cover the area to achieve the effect of the deletion. And the above businesses restore the deleted software, it is to retrieve the markup, and then return the file back. Do you have a way to permanently delete The technical experts statement makes people shudder, the deleted documents can be retrieved, then what security can there be? Reporters found that businesses also provide another service: permanently deleted. The service charges 490 yuan, and promises no one can use any software and restore tools after completely deleted. Permanent delete requires professional personnel to enter the cloud background operation, can permanently delete account information, but will not see the content. Tian Jiyun, a technical security expert at the top, argues that businesses may be able to remotely install a software similar to a file smashed in a phone to achieve an unrecoverable effect. First install the smashed files, fill the space with duplicate files, then delete them, mainly for small white users. Sun Weibo also said that if the file to be prevented from being deleted is restored, it can be achieved by repeating the memory area of the erasure file, and the actual storage location of the deleted file is covered many times to increase the difficulty of the file recovery. But even so, it is still impossible to ensure that deleted files can not be restored. This is because by deleting files and replicating a large number of useless files to fill the storage space, it is not 100% to confirm that it is impossible to recover, but only to reduce the possibility of recovery. Sun Weibo said. Theoretically deleted files can be retrieved, even if the data storage area is erased many times, it can still be recovered. But this is not what ordinary recovery software can do. Is it so difficult for ordinary people to delete a file? This is not the case. Sun Weibo suggested that ordinary users should not worry too much. There are also some mobile phone file destruction software on the market, which may be enough for ordinary people. Privately, however, he revealed that he would never sell his old cell phone to protect privacy. (quietly ask, is your old cell phone still in your own hands?) And if you really want to delete the information in the device once and for all, is there any way? The answer of the two safety experts is astonishing: the safest and safest way is blister hammer and physical destruction. Does it say this? I suggest here a picture of a triad throwing a cell phone into the sea in a movie. Sun Weibo quipped. In his disciples, undercover Daniel Wu threw his cell phone into the water after receiving his command. (Xiaobian tried to find a picture, though you may not see Daniel Wu throwing a cell phone) this article source: Beijing News Editor: Yang Qiang _NN6027
