Recommended Posts

I'm not sure if anyone is aware of this, but there's been a recent exploit found in HTTPS encrypted connections. We were actually discussing this in college yesterday.

A security researcher has discovered a critical security bug in multiple F5 firewalls and load balancers that causes HTTPS encrypted connections to leak sensitive data. The bug affects almost 1,000 popular websites and website owners are advised to check for the vulnerability urgently.

The security flaw, known as Ticklebleed, was discovered by Cloudflare cryptography engineer Filippo Valsorda. Some packets – a unit of data routed between an origin and destination on the internet – sent by a Cloudflare customer using the Railgun web optimisation tool caused an error that confused Cloudflare's Railgun TLS stack.
