1, the following matters should be paid attention to in preventing online fraud. Someone wants a verification code. Don't give it, the verification code is very common, but it is not a simple number, which means authentication! Don't provide others with a verification code of unknown origin that you don't know, especially strange numbers. Once the criminals get the verification code, the consequences are unimaginable! There is a link in the short message. Don't click, friends should remember: links are pits! Although there are security links sent by banks and other institutions in short messages, pseudo base stations and rebranding software have just died out and started again. Liars always have various ways to disguise themselves. Many relatives can't tell the truth from each other's short message number, short message content and link form. Therefore, children are advised not to click on any links in text messages. Especially for Android phone users, it is more important to guard against Trojan virus.
2. The phone does not display the number. Don't answer, at present, any government, enterprise, bank, operator and other institutions have official telephone numbers. "Don't show the number" basically comes from VoIP, either advertising or fraud. In short, hang up when you see a phone with no display number. Ask for your bank card number. Needless to say, whether it is a phone call, SMS, QQ chat or WeChat conversation, you will never mention information such as bank card number, password, ID number and medical insurance card number, so as not to be used by scammers. Even if you use a well-known number to chat with WeChat, you should pay attention to prevent your friends from being stolen.
3. You can call some numbers to check whether it is true or not. The scammer will call you by imitating the official customer service of operators and banks through virtual number change software. Recently, criminals used the rebranding platform to impersonate "China Mobile International Roaming Service Hotline1380010186" to defraud users' information. In this case, friends can hang up the phone, take the initiative to dial the relevant number (don't call back directly), connect to the real customer service hotline, and know the truth after careful inquiry.
4. Money can only go in and out, and any request for payment and remittance should be doubted! What child is in hospital? Please don't believe when you are accused of paying a deposit or something. The police suggested that even if you really want to remit money, you'd better choose to go to the offline bank counter, explain the situation to the bank counter staff and consult more people.
