O=Kaspersky Lab ZAO, CN=Kaspersky Anti-Virus personal root certificate O=Kaspersky Lab, CN=Kaspersky Anti-Virus personal root certificate Well, here is a list of some of these kind of certificates we found (there are hundreds of unique ones we found.) Ok then, who might be using this method in their products? So the options are don’t decrypt, allow criminals infect our users….or decrypt and protect the users…… Is there any other way of doing it? We are in constant search to improve our user experience and yes there are some other ways but they are yet to be proven as a good working alternative. And that is why these local https proxies are used so that the security product can have access to content to check for malicious activity.ĭo I like it? No. How can your content filtering product classify a website if its encrypted? Of course it can’t! That’s another reason why it must be decrypted. This is also a problem for content filtering products. That means as long as the criminals can have an encrypted channel to your computer they can push down all the malware they want and because you can’t decrypt the content you won’t know. Hmm…so the local application must install a rootkey so that it can read the encrypted content! Sounds bad right? Well, how else can you check the content for anything malicious in it, unless you decrypt it? Of course you can’t. The proxy is effectively operating a man-in-the-middle attack, allowed by the client’s trust of a root certificate the proxy owns. In such situations, proxy analysis of the contents of a SSL/TLS transaction becomes possible. Consequently, a root certificate generated by the proxy is installed into the browser CA list by IT staff. In a workplace setting where the client is managed by the organization, trust might be granted to a root certificate whose private key is known to the proxy. The SSL/TLS chain-of-trust relies on trusted root certificate authorities. Web filtering proxies are not able to peer inside secure sockets HTTP transactions, assuming the chain-of-trust of SSL/TLS has not been tampered with. What is it, well will explain it in more detail. ![]() With what is happening in the market place with superfish, there is a “realization” of an old and established method called “HTTPS Local Proxy”. ![]()
