Is the FBI's Fitness App a Cop?Sep 29, 2018
For site security purposes and to ensure that this service remains available to all users, all network traffic is monitored in order to identify unauthorized attempts to upload or change information or otherwise cause damage or conduct criminal activity. To protect the system from unauthorized use and to ensure that the system is functioning properly, individuals using this computer system are subject to having all of their activities monitored and recorded by personnel authorized to do so by the FBI (and such monitoring and recording will be conducted). Anyone using this system expressly consents to such monitoring and is advised that if such monitoring reveals evidence of possible abuse or criminal activity, system personnel may provide the results of such monitoring to appropriate officials.
That fine print raises the question of whether the FBI was using some sleight of hand to gain access to users' data. And CNBC noted that while the app apparently accesses both a device's GPS and accelerometer, it's not listed in the location services section of iOS settings and there's no clear in-app notifications that it enables the accelerometer.
So, to recap: There's no evidence that the FBI's app is tracking your movements, though it might be collecting standard metrics like how often you use the app.
But the FBI also has other dubious ways to track people of interest that are probably more effective than releasing an app secretly primed to spy on random users. For example, as the Intercept reported earlier this year, Section 702 of the Foreign Intelligence Surveillance Act allows the National Security Agency to "spy on Americans' transnational communications without a warrant so long as the 'targets' are not Americans," though documents leaked by former CIA employee and intelligence contractor Edward Snowden shows the program sucks up large swathes of domestic communications.
Section 702 has no controls on how that data can be used, giving the FBI and other federal law enforcement agencies the opportunity to collect it without a warrant. A bipartisan reform effort earlier this year failed after key Democrats failed to support it.
