I suddenly received a dunning call for no reason, but there was no loan. What happened?

1. It is possible that the information has been stolen. After it is clear that you have no loan, but you do owe a certain amount of loan, you need to call the police to solve the debt dispute.

2. If the information is not stolen, it may be that a friend owes an online loan, so you need to call to check whether the friend owes a loan.

3. I may have visited the loan website, which led to the disclosure of personal information. Lending companies will use this as an excuse to attract new users and should be more cautious when dealing with similar incidents.

Methods to prevent information leakage:

1. When registering on some small websites or unknown websites, don't fill in real personal information carefully. Some small websites are vulnerable to hackers because of weak security measures, which leads to the disclosure of registered user information. At the same time, the staff management system of these small websites is not perfect, which may lead to the staff leaking user information to criminals.

2. Regularly kill Trojans on mobile phones and computers. Mobile phones and computers may be infected with Trojans during use, and these Trojans will send the information in the mobile phone or computer to the location designated by the writer. Therefore, we need to regularly use security tools to kill viruses on mobile phones and computers in parallel. At the same time, we should develop good online habits: do not install software of unknown origin, do not open dangerous links, and do not browse illegal websites.

3. Carefully upload photos of ID cards, and add words indicating the purpose to the photos when uploading ID cards. Password retrieval, payment tool authentication and online credit card application all need to upload ID card photos, so be careful. When uploading a photo, you must add a text watermark to explain the purpose of the photo. The watermark should overlap with the text of the ID card to a certain extent, not all in the blank space.
