In real life, there are some criminal routines that use information asymmetry to cheat, and the typical ones are called impersonating acquaintances, such as impersonating your leaders, such as impersonating your distant relatives. This kind of fraud is often carried out after you fully understand your information and personal situation.
Our information must be well protected to prevent criminal suspects from using our information, or from using other people's information to impersonate acquaintances to defraud us. Be sure to confirm when transferring money or asking for information verification code. Don't believe what we see. Maybe I can send you a video or voice when I confirm the information. Remember, this is not credible, you must follow the specified action. What do you mean by designated action? For example, please raise your left hand or make a video. In this case, you must absolutely confirm whether the other party really exists. Because their fraudulent means of posing as acquaintances are very "in place" now, he will ambush in advance, maybe for months or even half a year, and they will all ambush in advance. So be sure to confirm your identity when transferring money or giving information and verification code.
