Passive WiFi Tracking

Doesn't iOS 8 do dynamic Mac addresses now? This would mitigate most privacy concerns from WiFi tracking.

It does but only if the device is locked and not associated to a wifi network. Even if those conditions are met, the device will only broadcast the "random" mac on set intervals and the locally generated mac will always have the second-least-significant bit set to 1.

From a consumer perspective, it's quite easy: to prevent being tracked, don't walk around with wifi turned on.

From an engineering perspective, toss out any mac with the U/L bit set to 1.

So that's why so many malls have 'free' wireless :-)

no, doesn't seem to. I'll report back after I setup my tracker in a few days http://www.imore.com/closer-look-ios-8s-mac-randomization
