Spotlight on different types of fraud

The increasing digitization of our everyday lives also increases the possible avenues of attack available to cyber criminals. They constantly make use of new methods to obtain data and money. That’s why it’s crucial to be able to recognize the different types of fraud. We constantly monitor how the threats are changing.

  • Scammers are currently sending phishing letters containing a QR code by post, claiming that they are from PostFinance. The QR code leads to a phishing page. The title of the letter is “Access to e-banking needs to be reactivated”. PostFinance does not send this type of letter.

    Please do not follow the instructions in the letter and destroy the document.

    If you have received this letter, please contact our hotline immediately on 0848 888 710 (max. CHF 0.08/min. in Switzerland).

    You can find more information on other types of fraud in the blog post "Scammers’ tactics. What you need to know".

  • Fraudsters call customers and pretend to be PostFinance employees. The purpose of the call is to gain access to e-finance. A commonly used pretext is that the victim’s e-finance has been hacked. Victims are urged to install software or apps on their computer or smartphone in order to carry out a security check. Hang up immediately if you receive a call like this – it’s a scam.

    • install third-party software on your computer

    • tell them your security elements
    • switch off security functions on your devices

  • Cyber criminals also like to find victims on online marketplaces such as Ricardo, tutti.ch or Scout24. For example, by offering bogus goods and bargain offers that are never delivered. Or by posing as fake buyers and pretending not to be able to inspect the goods, but paying for them in advance. Phishing links are then used to steal data in a sophisticated way. You can read more about the process in this blog post.
