Bitdefender Finds 'Hypervisor Wiretap' For Reading TLS-Encrypted Communications (helpnetsecurity.com)

Orome1 quotes a report from HelpNetSecurity: Bitdefender has discovered that encrypted communications can be decrypted in real-time using a technique that has virtually zero footprint and is invisible to anyone except extremely careful security auditors. The technique, dubbed TeLeScope, has been developed for research purposes and proves that a third-party can eavesdrop on communications encrypted with the Transport Layer Security (TLS) protocol between an end-user and a virtualized instance of a server.
Bitdefender says the new technique "works to detect the creation of TLS session keys in memory as the virtual machine is running." According to HelpNetSecurity, this vulnerability "makes it possible for a malicious cloud provider, or one pressured into giving access to three-letter agencies, to recover the TLS keys used to encrypt every communication session between virtualized servers and customers. CIOs who are outsourcing their virtualized infrastructure to a third-party vendor should assume that all of the information flowing between the business and its customers has been decrypted and read for an undetermined amount of time."

This isn't a big deal, it's fucking huge.

TLS is in just about everything and if they can unwind that realtime, they can no doubt unwind some other encryption implementations sitting on top. #No_more_secrets.
