Phishing scams using postal mail have been increasing in Germany and Austria. These crimes exploit traditional postal mail while integrating digital technology to steal recipients’ personal information.

In Germany, fake mail impersonating banks or public institutions has been discovered, often containing QR codes. When recipients scan these codes without suspicion, they are directed to a fraudulent website that closely resembles the official site of the institution. This site prompts users to enter financial information, which is then immediately transmitted to scammers, leading to account hacking and financial losses. These tactics are becoming increasingly sophisticated, extending beyond fake invoices to counterfeit tax notices that appear to be from government agencies.
Similar cases have emerged in Austria. Scammers distribute yellow postal notices that resemble failed delivery slips, also featuring QR codes. When recipients scan the code, they are redirected to a fake site that mimics an official tracking page and are prompted to enter personal information. If they provide their address or credit card details, the information is instantly sent to scammers, exposing them to further phishing attacks or direct financial fraud.
Mail-based fraud cases are occurring worldwide. In the United States, phishing mail impersonating the United States Postal Service (USPS) has been reported. These fraudulent letters include a message stating that “verification is required due to a delivery issue,” along with a URL leading to a fake website. Once recipients visit the link, they are prompted to enter their personal information. Notably, some fraudulent USPS mail is designed so convincingly that recipients are led to believe a package has gone missing.
In Australia, scammers have impersonated the police by sending fake fine notices. These letters threaten legal action if the recipient does not pay the fine immediately. The scam directs users to a fraudulent website where they are tricked into entering credit card details or making direct payments.

Japan has also seen cases where fake mail impersonating financial institutions has been discovered. These letters include a QR code prompting recipients to update their passwords. When scanned, the QR code leads to a fake login page that looks almost identical to the official banking website, tricking users into entering their account credentials, which are then stolen by scammers.
Since physical mail provides a sense of authenticity, it has traditionally been considered more trustworthy than email. However, as postal fraud incorporating digital elements becomes more prevalent, increased security awareness is essential.
Recipients must always verify the sender’s identity and carefully review QR codes or website links included in unexpected mail. Extra caution is required for documents that appear to be from financial or government institutions, and it is safer to verify the information directly through the institution’s official website or customer service. If suspicious mail is received, recipients should contact the relevant institution or report it to local law enforcement immediately. In case of a security breach, swift action is crucial to prevent further damage.
Organizations issuing invoices via QR codes must also consider alternative payment methods. Many utility bills, including gas, electricity, and apartment management fees, incorporate QR codes. Proactive measures by businesses and institutions can help mitigate the risks of fraud.
As digital technology advances, new types of scams continue to emerge. Therefore, maintaining vigilance and implementing timely preventive measures is more important than ever.
