The Health Insurance Organization (OHI) warns beneficiaries of the system about incidents of sending false and malicious text messages to mobile phones, which appear to come from GeSY, using the name GESY, with an announcement on Friday 14/11/2025.
As stated, OAU and GeSY have nothing to do with the specific messages, which misleadingly inform the recipient that he must follow a specific electronic link in order to correct his personal information.
It is emphasized that OAU will never ask for passwords, login details, payment details or any other personal data via text messages (SMS), nor will it ask citizens to make any financial transactions via links.
In case users receive a message of this type, please do not open the link and delete the message immediately, the announcement concludes.
