　　At the beginning of the new year, cybersecurity issues have once again become the focus of people's attention. The entire IT industry has fallen into two major vulnerability incidents: chip "meltdown" and "ghost"; Today's headline has been accused by users of having "microphone monitoring" issues ..... In the Internet world, personal data generated by the Internet is growing exponentially, and users are increasingly paying attention to the problem of information leakage and starting to refuse to "run naked" on the private Internet. Identifying vulnerabilities early and preventing them before they occur is the way to solve problems. Chinese mainstream Android apps have been exposed to the risk of "application cloning". Yesterday, Tencent Security Xuanwu Laboratory and Zhichuang Yu 404 Laboratory officially disclosed their attack threat model "application cloning" at a joint press conference. The head of Tencent Security Xuanwu Laboratory, Yu Yang (TK instructor), stated that this attack model is based on some basic design characteristics of mobile applications, so almost all mobile applications are suitable for this attack model. From the perspective of this attack model, many security issues that were previously thought to pose little threat and were not taken seriously by vendors can easily be "cloned" into user accounts, stealing private information, * * accounts and funds, etc. On the spot, Alipay was taken as an example to show the effect of the "application cloning" attack: when you click a website link on your mobile phone, you can see a normal looking Alipay red packet grabbing page, but once you click it, the nightmare begins. The account was "cloned" into the "attacker"'s mobile phone in a second, so the attacker can view the user information at will and use your Alipay to consume. This is a typical way of exploiting vulnerabilities to transmit malicious code at present. TK sect leader said that clicking on malicious links on mobile phones will completely control vulnerable applications. The TK leader stated in response to a reporter's question that this type of attack on text messages should be indistinguishable to users themselves and should not appear to be any different from other text messages. It is possible that the attacker is not on your friend's contact list, and you may have received an unknown number, which could alert you. This makes people feel creepy. Tencent stated that after testing, "application cloning" is effective for most mobile applications, with 27 out of 200 mobile applications found to have vulnerabilities, accounting for over 10%. The vulnerability discovered by Xuanwu Lab this time involves at least one app in the domestic Android application market, such as Alipay, Elema and many other mainstream apps, all of which have vulnerabilities, which affect almost all domestic Android users. After discovering these vulnerabilities, Tencent Security Xuanwu Laboratory reported relevant information to the manufacturer through CNCERT and provided a repair plan to prevent the vulnerability from being exploited by criminals. Discovering vulnerabilities is not difficult, but really thinking about defense issues can be very headache inducing. TK instructor said, "The vulnerability issue is actually very clear, at least we have figured out how to fix it, and we can also inform some vendors. However, in the longer term, if we really want to solve the security problem, it cannot rely on a certain link and users to pay more attention. It requires everyone to do a good job in every link of the entire chain, of course, it is a good state." Zhou Jingping (Black Brother), the security officer of Chuangyu 404 Laboratory, said that the "application cloning" vulnerability attack, the risk points involved in the entire attack are actually known. This vulnerability was discovered in 2012, and in March 2013, Black Brother mentioned this risk in his blog. At that time, he purchased an HTC and wanted to study the risks of the Android system. On a mobile app, for example, if you log in to Weibo with your phone, when you exit the Weibo process or close your phone, and then restart and reopen Weibo, you will find that it is still in the login state. What would be the effect if the relevant application data on this phone is moved to another phone? When transferring Weibo account data to another phone, of course, there are also some data related to the phone involved, and it will complete the login process on the other phone. He reported the relevant issues to Google, but did not receive a response. Zhou Jingping said that truly thinking about defense issues can be a headache for many people and companies, even if you solve this problem, there may be other issues as well. We need to constantly adjust the architecture and modify the design framework. We also need to consider whether solving your security issues will bring some performance issues to users. Network security risks are often present and not difficult to detect, but there is still a long way to go in terms of attaching importance to security and truly solving the problem. There is also an issue of attack cost involved here. To master relevant attack techniques, some attacks have very high costs, but why do vulnerability researchers spend a lot of effort and cost to study them? Zhou Jingping said that we hope to be ahead of the attackers. For those who engage in black industry or malicious activities, before they discover this, we report to some manufacturers and regulatory agencies to solve the problem and bring security to everyone.

　　The invention of lawn mowers has reduced people's working hours, reduced labor output, and further developed the labor of workers. Workers no longer have to work time-consuming and labor-intensive, and have provided us with better services. At the same time, it has a certain level of noise, and many lawnmowers make loud noises, affecting people's normal lives.

　　4. The new machine cannot be used at high speed. Please run in at low speed for 3 hours (equivalent to 5 pots of oil).

　　Clean the front filter every 25 hours with a front air filter, and clean the paper core every hour. When there is a lot of dust, it should be more frequent. The cleaning of the front air filter is the same as that of the foam filter element. The paper filter should be lightly tapped on a flat surface.
