Apple Responds to 'Masque Attack' Vulnerability, Not Aware of Customers Affected by Attack

Just a couple days after the discovery of an iOS vulnerability referred to as Masque Attack because of its ability to emulate and replace existing legitimate apps with malicious ones, Apple has responded in a statement to iMore. 

"We designed OS X and iOS with built-in security safeguards to help protect customers and warn them before installing potentially malicious software," an Apple spokesperson told iMore. "We're not aware of any customers that have actually been affected by this attack. We encourage customers to only download from trusted sources like the App Store and to pay attention to any warnings as they download apps. Enterprise users installing custom apps should install apps from their company's secure website."

Masque Attack works by luring a user to install an app outside of the iOS App Store by clicking a phishing link in a text message or email. For example, a user could be prompted to download a new app in a text message that says something like "Hey, try out Flappy Bird 2". A user is then directed to a website where they're prompted to download the app, which will install the fake app over the legitimate one using iOS enterprise provision profiles, making it virtually undetectable.

Masque Attack in action
Earlier today, the United States government issued a warning about Masque Attack to iOS users. The vulnerability was discovered just a week after reports of malware called WireLurker surfaced. WireLurker is able to attack iOS devices through OS X using a USB cable. Both vulnerabilities are unlikely to affect the average iOS user as long as Apple's security features are not bypassed.

Both WireLurker and Masque Attack can be avoided by staying away from suspicious apps and avoiding links that prompt users to install apps outside of Apple's App Stores.

why is being able to install faked apps on iPhone considered a vulnerability, when on every other OS the same thing could happen and they call it "open."

Because Apple always claims that their "closed" system is more secure than those others due to the review process?

Frankly, I don't understand why some people on this forum keep downplaying these security flaws. Perhaps they think they need to "defend" Apple, but that is misguided IMO. The "fappening" made it very obvious that Apple doesn't necessarily act to improve their security policies without public pressure. If that hadn't happended, we'd probably still have the weak iCloud security policy and incomplete 2-factor authentication. Public attention can only help to make the system more secure for everyone by forcing Apple to act.

Because the apps replace an app that is already on the phone that is signed by a different developer. My guess is Apple is doing their usual "there is nothing to see here", while they are working to fix the issue as quietly as possible.

Quite honestly this has already run its course. Enough already.

Indeed. Count on MR to run a sensational story about a trivial threat. After all, gotta get those ad impressions!

It'll have run its course when Apple fixes the problem. You should not expect or want any less.

While this is a legitimate issue, it's not specific to ONLY iOS. It is a phishing trick than any software can run in to on any system. If Apple fixes this, i'm impress since this is still and issue on every other system. You still get warning emails from your IT guys for not clicking on strange links, dont you? You can't fix stupid (ignore warnings) or greed (free apps).

I think people who are defending Apple is trying to get this point across. there're multitude of apple haters that are trying to make this an iOS issue only hence the need to counter their point. Beside , there's nothing wrong with defending a product/brand than you like, not that they need defending.

Adobe Photoshop? Microsoft Office for OS X? Are these gold standards available on the Mac App Store?

I don't think so...and to install them you have to break security code and change your settings, and allow untrusted installs...

Oh no! Apple doesn't want you installing these evil programs. They want you to use only Pixelmator and Pages...

Right...


Masquerade Attack is an iOS exploit and you are referring to OS X apps. Two different operating systems with two different App Stores.
