The critical Firefox vulnerability being actively exploited in the wild to unmask Tor users has been patched with the release of new browser updates. Both Mozilla and Tor Project has patched the vulnerability that allows attackers to remotely execute malicious code on Windows operating system via memory corruption vulnerability in Firefox web browser. Tor Browser Bundle is a repackaged version of the open-source Mozilla Firefox browser that runs connections through the Tor anonymizing network configured to hide its user's public IP address. However, the exploit code released by an unnamed online user was currently being exploited against Tor Browser users to leak the potentially identifying information of Tor users. "The security flaw responsible for this urgent release is already actively exploited on Windows systems," an official of the anonymity network wrote in an advisory published on Wednesday.  "Even though there is currently...no similar explo

Firefox 37 arrives with Opportunistic Encryption support

Mozilla has rolled out the latest Version 37 of its Firefox browser for Windows desktop, Mac, Linux and Android operating systems. The new release also adds patches for 13 different security advisories along with some new security improvements as well as user-experience features. The biggest security feature added to Firefox 37 among others is the "Opportunistic Encryption" (OE) for servers and websites that support " HTTP/2 AltSvc. " Opportunistic Encryption (OE) allows Firefox browser to encrypt the traffic over plaintext HTTP connection without any need to authenticate it. This will help you to create, not complete, but some confidentiality from attackers to eavesdrop on your connection. So Opportunistic encryption can be implemented with very minimal changes to an existing IPsec implementation. The move by Mozilla is really a bonus for HTTP users with no encryption measure at all, but still it is not as good as authenticated encryption
