"I didn't expect that swindlers would cheat with commonly used work apps." According to media reports, recently, many people have encountered "shared screen" fraud. In such fraud cases, swindlers generally first fake the identity of police, judges or bank employees to deceive the victim's trust, ask the victim to download some common or specific conference apps, in the name of assistance, deceive the victim to open the sharing screen and wait for the opportunity to steal the victim's bank card account number, password and other property information. Under the linkage of public security and the media, the overwhelming anti fraud publicity gradually improves people's awareness of anti fraud. They will take the initiative to reject all kinds of uncommon apps and all kinds of operations with obvious risks, which makes the road for swindlers narrower and narrower. However, when people receive a call from a liar and doubt it, the liar asks people to download commonly used software, which will make people relax their vigilance and feel that "there should be no problem with commonly used software". Some victims do not know that when sharing the screen, swindlers can fully see their various operations and input information. Swindlers' behavior is hateful and shameful, which objectively shows that not only citizens' awareness of anti fraud needs to be continuously improved and strengthened, but also it is urgent to protect personal privacy in multiple ways. The reason why fraud using "shared screen" can succeed is that it takes advantage of the security "loopholes" of mobile phone software to display all the information, so that the liar can use a small screen to obtain the key information of the victim. Therefore, all kinds of conference software and financial apps should repair these hidden dangers as soon as possible. The conference software needs to add security tips. When the user opens the shared screen, highlight the property risks that the user may encounter when using the "shared screen" to arouse the user's awareness of prevention. At the same time, if the privacy policy permits, once it is detected that the user opens the financial software or carries out financial operations, the relevant information shall be actively blocked. Financial apps should also take relevant protective measures: on the one hand, when it is detected that information sharing software such as sharing screen is running, the user should be prompted to cut it off immediately; On the other hand, we should also strengthen the construction of safe keyboard and other applications, cover the key input information, and prevent the "peeping" of other software. It is not enough to repair security vulnerabilities only technically. We should also use technical means to establish a funnel-shaped anti reporting network. When various apps detect that users have opened the sharing screen and transfer money to strangers, we should gradually raise the warning, and notify the police as soon as possible when it reaches a certain level. Of course, to prevent Telecom fraud, in the final analysis, we should enhance citizens' awareness of anti fraud, not only see the moves, but also take precautions. The so-called "see the move and remove the move" is to constantly find new situations, solve new problems, timely follow up all kinds of new fraud methods, inform them as soon as possible, and conduct all-round and multi angle publicity with the media. The so-called prevention is to carry out anti fraud training for citizens and immediately think of what to do when people encounter suspected fraud. It is undeniable that fraud essentially takes advantage of the weakness of human nature. When people are always careless, thinking blind spots or do not pay attention for a while, swindlers compile all kinds of scripts and scripts to expand people's cognitive errors and do not give people time to "breathe" in their thinking. No matter how many tricks there are, the core is to cheat the trust of the victims. Therefore, it may be better to cooperate with publicity to improve people's anti fraud awareness and train people's stress response when encountering several key actions.
