PayPal is one of the best-known payment services in online trading. But there are also numerous risks lurking when paying online.

For example, the Federal Criminal Police Office warns of a scam on classified ads. PayPal also has another scam that criminals can use to get your money. If you want to send money to friends or family using PayPal, you usually use an email address. Alternatively, you can also do this using your PayPal login name or mobile phone number. The money can be accidentally sent to the wrong person. If a stranger sends money to you, you shouldn't keep it. This could be considered “unjust enrichment”. PayPal advises on the website to contact the payment provider if you receive suspicious messages. “Do not open links, download attachments, or call any phone number that may be provided,” it says. The scam is already known on Reddit. ‘I would be very careful and call Paypal and tell them about it,’ one comment said. Only last year did the consumer advice center warn of a Paypal trap in fake shops.
