Jefferson's Wheel

Karsten Nohl (SRG CpE PhD 2009) was on CBS’ 60 Minutes (April 17) as their “Moment of the Week”: Hacking into a congressman’s phone.

We heard we could find some of the world’s best hackers in Germany. So we headed for Berlin. Just off a trendy street and through this alley we rang the bell at the door of a former factory. That’s where we met Karsten Nohl, a German hacker, with a doctorate in computer engineering from the University of Virginia.

Karsten demonstrated to the reporter how to track a Congressman’s location and listen in on phone conversations using SS7 vulnerabilities (for a real Congressman, Ted Liu of California, who actually has a CS degree). With permission, of course!

We wanted to see whether Nohl’s group could actually do what they claimed — so we sent an off-the-shelf iPhone from 60 Minutes in New York to Representative Ted Lieu, a congressman from California. He has a computer science degree from Stanford and is a member of the House committee that oversees information technology. He agreed to use our phone to talk to his staff knowing they would be hacked and they were. All we gave Nohl, was the number of the 60 Minutes iPhone that we lent the congressman.

An excerpt from the show was also the 60 Minutes Moment of the Week.

PCWord has a story about CNBC’s attempt to “help” people measure their password security: CNBC just collected your password and shared it with marketers: An exercise in password security went terribly wrong, security experts say, 29 March 2016.

Adrienne Porter Felt, a software engineer with Google’s Chrome security team, spotted that the article wasn’t delivered using SSL/TLS (Secure Socket Layer/Transport Layer Security) encryption.

SSL/TLS encrypts the connection between a user and a website, scrambling the data that is sent back and forth. Without SSL/TLS, someone one the same network can see data in clear text and, in this case, any password sent to CNBC.

“Worried about security? Enter your password into this @CNBC website (over HTTP, natch). What could go wrong,” Felt wrote on Twitter. “Alternately, feel free to tweet your password @ me and have the whole security community inspect it for you.”

The form also sent passwords to advertising networks and other parties with trackers on CNBC’s page, according to Ashkan Soltani, a privacy and security researcher, who posted a screenshot.

Despite saying the tool would not store passwords, traffic analysis showed it was actually storing them in a Google Docs spreadsheet, according to Kane York, who works on the Let’s Encrypt project.
