These TLS features are all things that current versions of Chrome and Firefox get right.
Kaspersky Cannot Guarantee Authenticity Of The Domain To Which Encrypted Connection Is Established Install A RootThey install a root certificate into the users browser and then they perform a so-called Man in the Middle attack.Superfish and Privdog did this in an obviously wrong way, Superfish by using the same root certificate on all installations and Privdog by just accepting every invalid certificate from web pages.By default Kaspersky intercepts connections to certain web pages (e.
In ESET TLS interception is generally disabled by default and can be enabled with an option. There has been a lot of debate and progress in the way TLS is done in the past years. Kaspersky Cannot Guarantee Authenticity Of The Domain To Which Encrypted Connection Is Established How To Do TLSA number of vulnerabilities in TLS (upon them BEAST, CRIME, Lucky Thirteen, FREAK and others) allowed to learn much more how to do TLS in a secure way. Modern browsers protect users much better from various threats than browsers used several years ago. You may think: Of course security products like Antivirus applications are fully aware of these developments and do TLS and certificate validation in the best way possible. After all security is their business, so they have to get it right. Unfortunately thats only whats happening in some fantasy IT security world that only exists in the minds of people that listened to industry PR too much. The real world is a bit different: All Antivirus applications I checked lower the security of TLS connections in one way or another. It is a technology that a lot of people in the IT security community are pretty excited about: It allows a web page to pin public keys of certificates in a browser. It is a very effective protection against malicious or hacked certificate authorities issuing rogue certificates. They wont enable the feature for manually installed certificates. Kaspersky Cannot Guarantee Authenticity Of The Domain To Which Encrypted Connection Is Established Software Like TheseThe reason for that is simple (although I dont like it): If they hadnt done that they wouldve broken all TLS interception software like these Antivirus applications. Kaspersky vulnerable to FREAK and CRIME Having a look at Kaspersky, I saw that it is vulnerable to the FREAK attack, a vulnerability in several TLS libraries that was found recently. Even worse: It seems this issue has been reported publicly in the Kaspersky Forums more than a month ago and it is not fixed yet. ESET doesnt support TLS 1.2 and therefore uses a less secure encryption algorithm. Kaspersky enables the insecure TLS compression feature that will make a user vulnerable to the CRIME attack. Both Avast and Kaspersky accept nonsensical parameters for Diffie Hellman key exchanges with a size of 8 bit. Avast is especially interesting because it bundles the Google Chrome browser.
