SourceVORACLE = CRIME for VPNs
VORACLE is not a new attack per-se, but a variation and mix of older cryptographic attacks such as CRIME, TIME, and BREACH.
In those previous attacks, researchers discovered that they could recover data from TLS-encrypted connections if the data was compressed before it was encrypted.
Fixes for those attacks were deployed in 2012 and 2013, respectively, and HTTPS connections have been safe ever since.
But Nafeez discovered that the theoretical points of those attacks were still valid when it came to some type of VPN traffic.
Nafeez says that VPN services/clients that compress HTTP web traffic before encrypting it as part of the VPN connection are still vulnerable to those older attacks.
...and that, ladies and gents, is why HTTPS is so important.
