Apple's TestFlight: One year later
5
It's been almost a year since Apple re-launched TestFlight. Apple had acquired TestFlight in 2014, and the much-anticipated announcement at WWDC gave many in the industry hope that TestFlight would spell the end for the numerous headaches associated with development builds and beta distributions. So where does TestFlight stand a year later? Has it lived up to these hopes? UDIDs...
Masque unmasked
Don't panic but do pay attention
12
"Masque Attack" is the new name—given by security firm FireEye—to an old trick intended to fool you into installing malicious apps on your iPhone or iPad. Most recently detailed by security researcher Jonathan Zdziarski, tricks like Masque Attack won't affect most people, but it's worth understanding how it works and, in the event you are targeted, how to avoid it.

Why most of us don't have to worry about 'WireLurker'

Is CurrentC helping you buy, or selling you out?
38
Just as quickly as CurrentC popped into the limelight, questions arose around the companies intentions. Even though I don't have an invite for CurrentC's invite-only mobile payments and loyalty rewards system, I decided to take a look. I posted some initial findings on Twitter and a brief summary on iMore, but wanted to do a more in-depth technical post for anybody who was curious....

Why is the CurrentC app collecting your device information?
29
Over the last few days, CVS and Rite Aid have disabled NFC technology at their retail outlets to prevent customers from using Apple Pay. It's been reported that this is due to an existing deal in place with a system called CurrentC, which involves the use of an app, QR codes, your bank account, and their servers. Walmart recently explained MCX's — the consortium behind CurrentC —...
Who's tracking who?
iOS 8 MAC address randomization and you
10
Normally when you're walking around with a WiFi-enabled device, if it's not connected to a network, it's broadcasting probes in order to try and find known networks. These probes would be sent using your phone's WiFi MAC address, which is a unique and normally persistent value. This means that anybody monitoring these probes, say in a department store for example, can persistently track...

Why bad bugs hit good people
53
Software is buggy. Humans write and test software and humans are imperfect; as a result, so is software. This is the reality of software and should come as a surprise to nobody. What can be surprising are the kind of bugs we actually see make their way out into the wild. We've seen two very prominent examples this week. The first was the release of iOS 8.0.1 on Wednesday which broke...

How Apple is keeping your iPhone and iPad safe!
3
Apple has posted a new version of their terrific white paper on iOS security, this one updated for iOS 8 an dated September, 2014. I haven't had time to read through it yet, but if last year's version is any indication, encryption enthusiasts should be in for a treat. The timing, immediately following iOS 8's release, and Tim Cook's letter on privacy, probably isn't a coincidence. Apple...

Location permissions in iOS 8: Explained

Every day our iPhones and iPads become a little more integrated in our lives. Every day they learn a little more about us and become more capable than they were before.

There's a seemingly endless list of apps that...
TestFlight in iOS 8: Explained
17
Beta testing apps has long been a pain point for iOS developers. So it's no surprise that the announcement of TestFlight as part of iOS 8 was met with much fanfare at WWDC 2014. Since Apple's acquisition of Burstly (makers of TestFlight), there has been a lot of speculation and hope that Apple could finally release a more friendly solution for handling the distribution of beta apps....
Understanding Apple's SSL/TLS Bug

Yesterday Apple released updates for iOS 6, iOS 7, and Apple TV to squash a security bug that affected SSL/TLS connections. Often times, security patches can fix obscure bugs that could only occur under the strangest of circumstances, and they get rolled in to larger updates that address many other issues. However, this fix warranted its own updates, both for iOS 7 and for iOS 6. So...

Earlier this week, security researcher Daniel Wood disclosed his findings on Starbucks' insecure handling of sensitive user information in their iPhone app. The sensitive information discovered includes usernames, passwords, emails, addresses, location data, and OAuth keys. While Wood's findings are valid, the interpretations of his findings have been inaccurate and exaggerated.

The Internet has been buzzing about Coin, a credit card replacement announced last Thursday. Currently taking pre-orders, and planning to launch Summer 2014, Coin is a credit card-sized device which is capable of storing and behaving as pretty much any card with a magnetic strip: credit cards, gift cards, membership cards, etc. Coin allows you to select which card you want to use, and...

After a failed attempt last month at rolling out BlackBerry Messenger (BBM) for iOS and Android, BlackBerry is giving the rollout another try. However, anybody who did not sign up previously is stuck waiting for their turn as BlackBerry slowly rolls out BBM to new users... unless you know how to skip the line.
Is iMessage secure? The good, the bad, and the complicated

Last week, researchers from QuarksLab gave a presentation at HITBSecConf2013 on the security of iMessage. The researchers sought to investigate claims made by Apple that nobody but the sender and receiver could read iMessage data thanks to their use of end-to-end encryption. While the researchers discovered that they were able to intercept and decrypt iMessages, Apple was quick to...
