1. First of all, veterans have encountered online fraud and need to try to stay calm. They should determine the losses, such as money and goods, and if possible, make a list of losses and report them.

2. Secondly, after determining the loss, you must call the police as soon as possible, and never contact the online fraudsters again to prevent being deceived twice.

3. Finally, you can try to stop the loss after the alarm, such as contacting the bank or courier company as soon as possible. In case of online banking fraud, if the account information of the fraudster is kept, you can immediately log in to the online banking and telephone banking of the other bank, enter the account number of the other bank, and intentionally enter the wrong login password for three times, so that the online banking and telephone banking transfer functions of the other party are temporarily frozen for 24 hours, thus winning valuable time for contacting the bank, calling the police and further stopping losses.
