james.wilson Posted August 1, 2010 Share Posted August 1, 2010 Engadget have a story about Chris Paget (rfid hacker) where he has fooled the gsm protection system and can listen into calls etc. This seems to be 2G only, but as the majority of dualpath signalling devices use this do we see this as conerning? http://www.engadget.com/2010/07/31/hacker-intercepts-phone-calls-with-homebuilt-1-500-imsi-catcher/ securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Guest Oxo Posted August 1, 2010 Share Posted August 1, 2010 Concerning? Yes as its intercepting the outbound call so to speak. Link to comment Share on other sites More sharing options...
hpotter Posted August 2, 2010 Share Posted August 2, 2010 might be listening in, but dont seem to be preventing the calls, or aint i reading it right? Link to comment Share on other sites More sharing options...
james.wilson Posted August 2, 2010 Author Share Posted August 2, 2010 as i read it, it fools the gsm device into thinking its a valid base station. I suppose you could then do what you want with that call. Pass it through to where its supposed to go... or somewhere else. Worse than a jammer as the system will beleive the signal has been passed. Any device IMHO thta uses gsm as its primary path is a concern. Id assume this wouldnt affect gprs. 3g has other issues as femtocells could be used in the same way. But id assume there is more security on this as its a newer std. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

hpotter Posted August 2, 2010 Share Posted August 2, 2010 eg G2 redcare: dont stu want ack from bt esp after period (eg 10 secs in alarm) or esp reports comms fail within 60 mins if polling failure? G3/4 obviously faster Link to comment Share on other sites More sharing options...
james.wilson Posted August 2, 2010 Author Share Posted August 2, 2010 Everything wants some sort of acknowledgments. But a SOHU. is a low security ack. Don't know what secure uses but I'd assume that would be relatively trivial to find out. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

hpotter Posted August 2, 2010 Share Posted August 2, 2010 do you think we're relying on the integrity of gsm network rather than encryption of messages within? well both i guess? Link to comment Share on other sites More sharing options...
james.wilson Posted August 2, 2010 Author Share Posted August 2, 2010 Is agree ie both. If the gsm network becomes public integrity will be as important as it is on up signalling. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
