What happens at Black Hat…
While trying to escape the Las Vegas heat during Black Hat last month, watchTowr Labs researchers decided to poke around for weaknesses in the WHOIS protocol. They claim to have found a way to undermine certificate authorities, which the world trusts to keep the internet safe by verifying the identity of websites.
In deploying the new WHOIS server, the team crafted a response to anyone that hadn't updated their client to use the new mobi address, and this response included ASCII art – obviously. In this case it's the company's logo, which looks like a castle watch tower. It also included fake WHOIS details indicating watchTowr as the owner for every queried entity.
Just the gov addresses alone belonged to America, Argentina, Brazil, Pakistan, India, Bangladesh, Indonesia, Bhutan, Philippines, Israel, Ethiopia, and Ukraine, we're told. "We're all very, very aware of how much certificate authorities have been targeted in the last ten years by nation states," Harris said."So our ability to then start issuing things like certificates for microsoftmobi and googlemobi falls into the playing space of nation states who want to use this capability to intercept internet traffic at a country scale, all the way through to targeting individual users to snoop on communications.
