If you get SMS messages on your phone and think you have two-factor authentication, you’re kidding yourself. That’s the message Nick Weaver and David Kris extract from two stories we cover in this week’s episode of The Cyberlaw Podcast – DOJ’s indictment of a couple of kids whose hacker chops are modest but whose social engineering skillz are remarkable. They used those skills to bribe or bamboozle phone companies into changing the phone numbers of their victims, allowing them to intercept all the two-factor authentication they needed to steal boatloads of cryptocurrency. For those with better hacking chops than social skills, there’s always exploitation of SS7 vulnerabilities, which allow interception of text messages without all the muss and fuss of changing SIM cards.
