[liberationtech] iPhones/iPads secretly track 'scary amount' of your movements

Thanks for the cellebrite.com info, they are mentioned in an article
posted today which notes that ACLU has submitted 70 Freedom of
Information requests to Michigan Police, but still without disclosure
about it's use of cellebrite technology

Cops refuse to say if they secretly snarf cellphone data

iPhone? More Like iSpy!

It's not just iPhones that record vast amount of data that can be easily
geo-located and reconstruct  person's movements,  networks, and personal
 communication - any cell phone going back 15 years stores  data through
log files, message  and SMS traffic that can be reconstructed and
retrieved to create pretty comprehensive profiles of usage and location.
 Devices that do forensic extraction (UFED) are quite widespread and in
use throughout police forces intelligence agencies as well as  most
cellular carriers  around the world. For those of you for whom  this is
a revelation, I'd advise you to take a look at this website of a leading
provider of UFEDs.  There are some interesting videos, and once you're
done,  take a look at where this company has  it's permanent
representatives.

Time for a reality check. Mobile phones are essentially digital dogtags
so if you're concerned about  the ability they have to track your
movements and  communications -  do like Osama, use  exclusively
off-line means through trusted intermediaries.  Otherwise  accepting
that cell phones are  a risk to privacy is just  the flip side of the
convenience that these devices bring.  With or without Apple  networks
are essentially  spiderwebs    -  that's the essence of modern signals
intelligence. 

It's worrisome that there are a lot of myths   among the activist
community about cell phone security. True, you can "drive up the
negatives" and make it  more difficult for a casual actor to scan or 
obtain PII  from your  phone ( so I  I agree with Nathan) -  but if
you're up against  well resourced opponents, most of these tools  plain
ineffective and their very presence on your phone may be more of a
giveaway that  actually makes you more  of a a target of interest.  
Unfortunately security is not a product or something you can buy
shrink-wrapped in code.  Its practice and process  and  ultimately comes
down to the risks you're willing to take in the service of an objective 
or cause.  And if you want to play in the big tent, it's  good
old-fashioned tradecraft and not better toys that make a difference.
