For several months now, security authorities have been observing an increase in fraud attempts using so-called SMS blasters. In this process, a large number of fraudulent text messages are sent within a short period of time.
25.08.2026 –In some cases, devices are used that mimic mobile networks and transmit messages directly to nearby smartphones. These messages often contain links to fake websites. For example, they claim that parking fines or other outstanding bills need to be paid. The aim is to steal card details and personal information.
Here’s how to protect yourself:
- Don’t click on links in suspicious text messages
- Always check payment requests carefully
- Never enter card details or personal information on unfamiliar websites
- If possible, disable the 2G function on your smartphone; SMS blasters exploit vulnerabilities in the outdated 2G mobile network standard.
It pays to stay alert! A quick safety check can save you a lot of trouble.
