The post discusses concerns regarding Vietnamese banking apps improperly using private iOS APIs, which violates Apple's guidelines for app security. The original commentary from developer @opa334 highlights the risks posed by these practices in contrast to established safety measures, like the software developed by the author, which is designed to detect malicious applications more effectively. Additionally, insights shared by other developers draw attention to the potential security risks associated with these home-grown systems that banks claim offer adequate protection. This situation raises questions about the compliance of financial institutions with industry standards and the need for better practices in app development and security management.
