Flaws Allow Every 3G Device To Be Tracked
mask.of.sanity writes "New privacy threats have been uncovered by security researchers that could allow every device operating on 3G networks to be tracked. The vulnerabilities could be exploited with cheap commercial off-the-shelf technology to reveal the location of phones and other 3G-capable devices operating on all 3G compliant networks. It was similar, but different, to previous research that demonstrated how attackers could redirect a victim's outgoing traffic to different networks."
I'm pretty sure the word flaw should be in quotation marks in this context.
Sure. If they know the IMSI of the mobiles that the protesters are using in advanced. This attack gives the TMSI of the device, which is a temporary identifier, and will change when the mobile roams outside of the current location area.
Then they need to set up compromised base stations all over the city if they want to track this protester, and I am sure that there are easier ways to go about that.
