SSL status of Taiwanese banks: a sad affair

Today there was a story on Hacker News, how someone tweeting a screenshot of a bank’s SSL certificate got harassed by the bank in Greece. This got me thinking about the status of the banks here in Taiwan, especially how this place is so wired and online now. So I took a list of taiwanese banks and run each of their sites through the SSL Test. From past experiences I haven’t had my hopes up, but boy is the result ugly…

SSL Test Overview

I had a list of 43 banks, and for a quick overview I took into account a few key features only. The first is whether there are any active vulnerabilities against the site according to the test (these were mostly CRIME, FREAK, and POODLE attacks). The second is whether RC4 encryption was enabled, as it is now prohibited, and having it on is an automatic Payment Card Industry Data Security (PCI) compliance failure, according to one of the commenters. Other various warnings are mentioned when something really stands out, they are not crucial but more nice to have (though I’d contend that Forward Secrecy and HTTP Strict Transport Security is more than “nice” for anything financial).

Edit: Since publishing this post, there’s a brand new password recovery attack against RC4, so it’s even more urgent to switch it off.
