ABout MasterCard data breach – Aug 2019

Preface: Still remember that when I was work in bank environment. Visa and Master payment solutions looks indeed secure. Those facilities are running in standalone machine. The communication protocol is the IBM SDLC communication. In order to communication with S390 mainframe. We setup data link switch in network switch and define VTAM major nodes on mainframe. Can we say the invention of internet jeopardize the world. Yes, it does.

Incident details: MasterCard said it was investigating a data breach of a loyalty program in Germany. There are about 90000 personal records was steal. Perhaps the actual figure has not been finalize yet! but rumor said that the leaked personal data is selling on darknet now. However, when we manually view the programming source it shown to us there is a lot of weakness on backend server. For instance, the backend system run on vulnerable Apache version. So i am imagine that whether there has possibility let attacker exploit CVE-2017-3167 to bypass the authentication on the front end web server then stolen the data?
