Last Friday there was news out of the Chaos Computer Club Congress in Berlin that two security researchers, Karsten Nohl and Sylvian Munaut, had successfully cracked the encryption used in the GSM cellular network. While not “VoIP”, per se, this is of interest to any of us working with VoIP as many VoIP clients are now working on “smartphones” running on top of the GSM network (like, oh, the iPhone, among others). Some of the articles on this topic:
- TheNextWeb: Hackers crack open GSM networks to eavesdrop on mobile calls
- InfoSecurity.com: Security researchers subvert GSM encryption
- eWeek Europe: Researchers Demonstrate GSM Phone Call Hack
The researchers are apparently not releasing their toolkit publicly, but obviously word of their success will encourage others to investigate further.
