Karsten Nohl on Cloud Hacking, Central Bank Ends SMS 2FA and Macron’s Filter: Commsrisk Show Episode 10

It is difficult to think of bigger names than Karsten Nohl (pictured right) in the arena of telecoms hacking. As a ‘white hat’ hacker he has identified and explained a series of vulnerabilities relating to GSM, GPRS, SIM cards and many other technologies that have been central to the evolution of modern communications. So we had better pay attention when Nohl observes how hackers could subvert the cloud servers used by comms providers and other businesses. Nohl joined us for yesterday’s episode of The Communications Risk Show to talk about hackers potentially gaining access to cloud containers and then breaching all the customer data and taking the network down.

Episode 10 also featured the regular team of presenters debating whether other countries will follow the lead of Malaysia’s central bank, which has ordered the country’s financial institutions to stop using SMS to authenticate users and their transactions. The conversation then went on to examine the reasons why French President Emmanuel Macron has promised to implement a new nationwide filter on scam messages sent by SMS and email, and the risks created by a new iPhone feature which gives users the ability to clone a voice in just 15 minutes.

The Communications Risk Show streams live every Wednesday at 4pm UK time. Producing a live show means everyone can ask questions of the guests and presenters. But if you miss a live webcast then you can always catch up with the video recording or the audio podcast soon after. Yesterday’s show can be replayed below.
