CNNIC Certificates

I thought I had done a post earlier in regards to Mozilla Revoking Trust in one CNNIC Intermediate Certificate. Turns out I had not. Also had planned on posting more about this earlier this weekend as Mozilla took further actions against the CNNIC certificate authority on Thursday, April 2nd. I did mention this briefly in the Firefox 37.0.1 Released post, but wanted to take a moment and explain about this in a little more detail. About 2-weeks ago on March 23rd, from the Mozilla Security Blog: China Internet Network Information Center (CNNIC), a non-profit organization administrated by Cyberspace Administration of China…

Google researchers announced recently of the POODLE (Padding Oracle On Downgraded Legacy Encryption) Attack which hackers take advantage of sites (around 0.3%) still using the outdated (introduced in 1996) SSLv3 security protocol. Mozilla has announced that SSLv3 will be disabled, unfortunately it won’t be until Firefox 34 which will be released on November 25th. However, user can (and are urged to) install the SSL Version Control extension which will disable SSLv3 on the fly. I would not be surprised though if Mozilla pushes out Firefox 33.1 update to have SSLv3 disabled in the coming days or weeks. Google Chrome is already testing changes to disable…

Browsers extensions are great as they enhance the usability and your experience with your browser. However, there are some extensions out there that will actually do the opposite. This seems to be a bigger problem for Chrome but there are a couple known ‘spying’ extensions in Firefox. These ‘evil’ extensions may track you or as in the case with Scott Hanselman inject ads into sites you are viewing. My perspective on JavaScript-based browser extensions has been far too naïve until this point. We were all burned by bad toolbars or evil ActiveX add-ons in the past, so when I run IE I run it with…
