I suspect that I have encountered fraudulent text messages .. Please help me analyze them.

This is a typical fraud, don't be fooled.

This kind of fraud is that the package contains prohibited items, pretending to be a courier company such as logistics to deliver goods to the victim, and then claiming that the package contains drugs or other prohibited items. Later, for the safety of the victim's funds, the staff posing as public security organs took the victim's deposit bank and bank card number and password, and then transferred the victim's deposit or asked the victim to transfer the deposit to the "safe account" provided by him.
