With Thailand rapidly moving to a full internet banking ecosystem, the demand for online security has never been needed more than it is today. As the security and privacy of internet users depend on HTTPS, a web encryption protocol, for securing communication between users and web servers, HTTPS is essentially the center of the web ecosystem today. Unfortunately, despite the increasing number of HTTPS adoptions, numerous studies have shown that a large number of websites have adopted HTTPS incorrectly, rendering users vulnerable to information leakages e.g., eavesdropping and man-in-the-middle attacks. The correctness of HTTPS deployment is even far greater for internet banking services due to carrying user’s sensitive information and being prime targets for criminal activities. In this paper, we present WEAPONS, a novel black-box testing tool for evaluating the completeness and correctness of web encryption deployment including the deployment of HTTPS, and web encryption-related mechanisms i.e., HSTS, secure cookie, HTTPS redirect, HSTS preload. We use WEAPONS to conduct an assessment of 8 popular internet banking websites in Thailand. We demonstrate that WEAPONS is able to find HTTPS deployment incorrectness. Several of these weaknesses can expose the affected services to man-in-the-middle attacks and sensitive data exposure.
