Mac News & Updates - 06/19/16

With WWDC happening this week there has been lots of Apple/Mac news, so I figured I would take this opportunity to put out a list of links and videos that I found worthwhile to read/watch. I hope to do this at somewhat regular intervals so keep an eye out for them! A good portion of these I’ve already tweeted out – but I’ve been told not everyone is on Twitter so here you go!

Videos:

WWDC Videos can be streamed on various Apple devices or thru the Safari browser – for you Windows folks, you can download them in the ‘Resources’ section of each link below. All videos can be accessed from the main page here, https://developer.apple.com/videos/wwdc2016/. I will highlight some of the videos I think are particular useful.

New Script – iOS Locations Scraper

Similar to my iOS Frequent Locations Dumper script, I wanted to extract the iOS locations that are stored in various SQLite databases and review them in CSV and KML output to make analysis easier. You can get the Python script here: https://github.com/mac4n6/iOS-Locations-Scraper

iOS is storing location data (Lats/Longs) in a variety of databases that are only accessible via physical access using a Jailbreak. Each database contains slightly different location data from Cellular (ie: LTE/CDMA), to Wi-Fi (war-driving type data), to application specific (Yelp, see example below). I still have quite a bit of research to do in this area to determine what all these points mean and how they are generated, and how long they persist for - thus a script needed to be created to make my life easier.

/private/var/mobile/Library/Caches/com.apple.routined/cache_encryptedB.db

/private/var/root/Library/Caches/locationd/

  • cache_encryptedA.db
  • cache_encryptedB.db
  • lockCache_encryptedA.db

The new iOS Locations Scraper script takes these extracted databases from a directory, looks at each table for a column labeled ‘Latitude’ and extracts the tuple data and writes it into a CSV and/or KML file. Examples of these files are shown below.

An example of the CSV output:

An example of the KML output in Google Earth (Note: A KML file can be opened in a variety of different tools):

CAVEAT: I wanted to make sure that I put this caveat out there. Some locations are fairly exact to where the device was located at a certain time, however others are more of a general location area (ie: cell tower location). The KML example above shows location artifacts from one database table (cache_encryptedA.db, LocationHarvest) in relation to the Yelp application. That's my iPhone tracking my location when I was using the Yelp app this weekend. (Pretty neat huh?)

For more iOS location-based information take a look at some of my other presentations:

BSidesNOLA Preso - The iOS of Sauron: How iOS Tracks Everything You Do

in ,

I was lucky enough to again be selected as a speaker at one of my favorite BSides conferences, BSidesNOLA (4 years running!). This one has THE BEST speaker party. Backyard tiki bar, homemade gumbo, boiled crawfish, jambalaya, bananas foster. If you want to speak at a fantastic forensics heavy security conference, I highly recommend this one!

I presented my newest presentation "The iOS of Sauron". This is a presentation that I will be continuously researching and updating so be sure to visit again to get the newest version. I hope to also write various blog articles going into more depth on some of the topics covered.

This is very much a pattern-of-life presentation - if you have a particular "pattern" you are looking for - let me know. If you think its important, I bet someone else does as well!

You can find the presentation here.
