Since Apple first launched Activation Lock, incidents of iPhone theft have dropped dramatically. Because the function makes iPhones far more troublesome for thieves to revenue from stealing, the idea is that many would-be iPhone thieves usually tend to go for the lower-hanging fruit of different smartphones which have fewer anti-theft measures baked in.
Nevertheless, the recognition and worth of the iPhone nonetheless makes it a fascinating goal, and for skilled thieves, the place there’s a will, there’s a manner. Though the Activation Lock itself should be safe, there are different ways in which criminals can try and bypass a locked iPhone by way of “social engineering” ways — convincing both Apple or the unique consumer to easily swap the function off.
We reported earlier this 12 months on a few of these strategies, which embrace producing pretend receipts to try to persuade Apple that the thief is the respectable proprietor of the stolen iPhone, in addition to phishing assaults directed on the unique proprietor to try to get them to produce their Apple ID and password, typically by way of a pretend “Discover My iPhone” web page or one other associated technique that convinces the consumer that their misplaced iPhone has been discovered, and that the poor sufferer merely wants to produce this data — and even disable Activation Lock themselves — in an effort to be reunited with their system.
Defeating Distant Wipe
Since customers who discover their iPhone lacking typically put it remotely into “Misplaced Mode” and provide a contact quantity within the hopes that an sincere particular person will provide to return into them, thieves can in fact use this data to contact the unique proprietor and try and rip-off them into giving up further data.
Nevertheless, a brand new report from Engadget reveals that thieves and hackers might be able to get extra data from a locked iPhone than they need to. In response to the report, the teenage son of main safety skilled Marc Rogers, technical advisor for Mr. Robotic and organizer of the world’s largest hacking convention, DEF CON, lately had his iPhone stolen, with the thieves resorting to some methods that baffled even Rogers.
As one may anticipate from somebody with Rogers’ credentials, his son’s iPhone was configured virtually as securely as an iPhone could be, with all the newest iOS updates put in and an precise robust password fairly than only a four-digit code.
Since this was my child we’re speaking about, the telephone was updated and had a powerful password and FaceID enabled, and activation lock was turned on. As quickly because the telephone was discovered to be lacking it was switched to Misplaced Mode and later a wipe command was despatched to it.
Marc Rogers, in an electronic mail to Engadget
Rogers additionally added that his son observed the telephone lacking lower than ten minutes after its theft and instantly “started safety protocols,” switching it to Misplaced Mode and later sending a distant wipe command.
Whereas this could have been the top of the story, Rogers shortly realized that he was coping with skilled iPhone thieves. Firstly, the iPhone had dropped fully off the grid, acknowledging neither the Misplaced Mode activation or the distant wipe. This led Rogers to consider that the iPhone had both been powered down instantly or positioned in a bag that may block radio frequency indicators.
Since skilled criminals are effectively conscious of Activation Lock by now, that is recognized to be par for the course when an iPhone is stolen by an skilled thief, and specialised luggage aren’t essentially required — even placing it inside an empty potato chip bag could be sufficient to dam mobile indicators from reaching the iPhone, thereby defeating makes an attempt to remotely wipe it. Alternatively, merely powering down the iPhone additionally works simply as effectively, and in both case, the thief takes the iPhone to a spot the place no sign can attain it earlier than powering it again as much as examine it.
Switching the iPhone off or blocking its mobile sign gained’t bypass Activation Lock, nevertheless it does stop the telephone from being remotely wiped, which implies that all the consumer’s knowledge — and phone data — stays theoretically accessible, merely hiding behind their password. As soon as an iPhone is remotely wiped, thieves have virtually no likelihood of getting any contact data that may very well be used to launch a phishing assault in opposition to the unique proprietor, and finally the hope is that they handle to attain an iPhone with an older iOS model with safety vulnerabilities or a quite simple passcode that make it attainable to hack into it.
Within the case of Marc Rogers, nevertheless, what occurred subsequent was extra stunning. Just a few days after the theft, the teenager started receiving “extremely focused messages utilizing data they’d apparently managed to extract” from his iPhone. Contemplating that the iPhone was operating the newest model of iOS and used a posh password, this data shouldn’t have been accessible by thieves.
In response to Rogers, the data included not solely the kid’s appropriate Apple ID and its related electronic mail deal with, but in addition the telephone quantity related to it, “despite the fact that the SIM card had been killed.” Utilizing this data, the attackers “despatched a spread of various messages attempting to a number of totally different social engineering ways” to try to get Rogers’ son to surrender his password or disable the Activation Lock himself.
The assaults had been made within the type of textual content messages and iMessages that had been made to appear like they got here from Apple, though the attackers additionally “rotated by way of a spread totally different cellular numbers” and iCloud addresses, prone to keep away from detection or just being blocked.
Rogers did some digging on-line and found how widespread of an issue that is changing into, with many customers who’ve misplaced their iPhones being directed to click on on hyperlinks in phishing messages that can redirect them to pretend “Discover My iPhone” pages.
Apple boards are filled with customers asking for assist after clicking on comparable phishing emails. After which their telephone is nearly immediately deleted from their account, by no means to be seen once more.
What was much more stunning to Rogers was how widespread these “spearphishing” assaults are and the way in which by which they’re getting used. Usually, Rogers notes, this sort of very personalised assault is used in opposition to “high-value targets” like administrators of firms and authorities officers. The truth that it’s now getting used in opposition to “bizarre smartphone customers” means that the instruments to launch these sorts of assaults have turn into commonplace.
Leaking Contact Data
Nevertheless, probably the most critical factor about Rogers’ expertise is that the thieves had been capable of acquire his son’s contact data from an iPhone that ought to have been well-secured, which means that there’s a nasty privateness or safety bleed taking place someplace within the system, whether or not it’s from the iPhone itself or through the service networks.
All smartphone producers and the cellular carriers have to learn the way the attackers are harvesting private data from their victims with nothing however a locked stolen telephone. Clearly they’ve discovered a route they’ll leverage to extract key items of data, possible by way of a multi-step course of. A thief shouldn’t be capable of extract the sufferer’s contact data from a locked stolen system.
There are additionally legitimate ways in which a thief may acquire contact data from a locked iPhone. For instance, there might have been uncleared notifications in Notification Heart that might show any variety of private particulars, along with widgets on the Right now display screen, and even playing cards in Apple’s Pockets app.
Notably, a bug found in iOS 13 a number of days earlier than its public launch allowed customers to bypass the iPhone lock display screen to view contact data, and whereas the problem was reported to Apple again in July, it wasn’t patched till iOS 13.1 was launched. Rogers doesn’t specify what model of iOS his son was operating, aside from that it was updated, nevertheless in an article by Rogers on Dark Reading, he notes that the theft occurred on June 30, through the San Francisco Delight Parade, at which period the newest non-beta model of iOS was 12.3.1 (12.3.2 for the iPhone 8 Plus). The iOS 13 public betas out there at the moment, nevertheless, would possible have suffered from this specific vulnerability.
What This Means For You
Whereas the concept thieves can get into your stolen iPhone is regarding, it’s nonetheless unclear from Rogers’ story precisely how a lot data they may entry, and even whether or not they obtained his son’s contact data from the iPhone itself versus utilizing different means. Actually, regardless of Rogers’ observe that the SIM card “had been killed,” it’s possible that the quantity was nonetheless saved on the cardboard itself, plus if the telephone remained out of information protection, any “kill” directions from the mobile service wouldn’t have reached the iPhone anyway.
Regardless, nevertheless, the identical fundamental web security guidelines apply right here when coping with a stolen iPhone, and irrespective of how badly you wish to be reunited together with your system, it’s essential to deal with any communications you obtain with a wholesome dose of skepticism.
- Don’t flip off Discover My iPhone. Ever.

Higher but, use the Discover My app on one other iPhone or iPad when you have one out there, even when it’s from a buddy or member of the family.
- Set a powerful alphanumeric password in your iPhone. One of many largest hidden advantages of Face ID and Contact ID is that you simply don’t have to kind in your password fairly often. This makes it a lot simpler to make use of a posh alphanumeric passcode, fairly than a four- or six-digit code that may extra simply be compromised by hackers. Right here’s methods to set one up.
- Disable Notification Previews for Delicate Apps. Even on a secured iPhone, Notification Heart could be a treasure-trove of data, so it’s a good suggestion to disable Notification Previews for apps that may present knowledge that you simply wouldn’t need anyone else — particularly a thief — to see. Plus, when you’re utilizing a Face ID outfitted iPhone, hiding your notification previews gained’t get in the way in which of seeing them your self, as they’ll routinely be unhidden as quickly because it acknowledges your face. See right here for the way to do that.
- Disable Lock Display Options. When you actually wish to ensure your iPhone is safe, you’ll be able to lock down your lock display screen even additional, stopping entry to the Right now View, Notification Heart, Management Heart, Pockets, and extra. Though this may occasionally make your iPhone rather less handy to make use of, it considerably reduces the quantity of data that may be out there to a thief, and once more with a Face ID outfitted iPhone, it shouldn’t be too cumbersome, as you’ll solely use most of those options once you’re taking a look at your iPhone anyway, by which case they’ll nonetheless be out there as soon as your iPhone acknowledges your face. Right here’s methods to change these settings.
- Act quick. In case your system is misplaced or stolen, don’t delay — allow Misplaced Mode instantly and when you’re involved about your delicate knowledge, set it to distant wipe.

Misplaced Mode additionally silences all alerts from showing on the system, bettering privateness and safety. It additionally instantly invalidates all your Apple Pay and scholar ID playing cards — even when your system isn’t on-line, and as safe as Apple Pay already is, this side alone is an excellent purpose to allow Misplaced Mode even when you suppose your iPhone has no likelihood of reappearing.
