“Apparently, even though they fixed the issue internally, OEMs did not apply the fix (perhaps they forgot or simply missed it),” Beniamini told TechCrunch in a message. (Google didn’t comment on the exact timeline that lead up to the patches.)

Still, the vulnerability lingered in Android long enough for Beniamini to discover his exploit. A Qualcomm spokesperson said the company discovered the same vulnerabilities exploited by Beniamini as early as August 2014 and made patches available to Google in November 2014 and February 2015.

We rolled out patches for these issues earlier this year,” a Google spokesperson said. Google issued two patches earlier this year to fix the problems Beniamini discovered.īut according to Qualcomm, Google should have known about the vulnerability since 2014. “We appreciate the researcher’s findings and paid him for his work through our Vulnerability Rewards Program.

In a blog post published last week, Beniamini outlined the process of breaking Android’s full disk encryption he exploited several weaknesses in Qualcomm’s security to pull the encryption keys off an Android device.īeniamini disclosed the issues to Android and Qualcomm and was paid through Google’s bug bounty program for his work. (Although it’s possible that the FBI did find a way to do this anyway, the method it used to break into the phone has not been made public.) New find, old bug

If Apple stored the keys in software, investigators might have been able to pull the keys off the device and run password guesses more quickly and without the risk of losing all the data on the phone. Because Apple stores encryption keys in hardware, investigators couldn’t circumvent some of the features the company uses to protect its devices, like time delays between password attempts and a device wipe after 10 incorrect password attempts. The hardware-software distinction became a key part of Apple’s fight with the FBI over unlocking an iPhone used by the San Bernardino shooter.

The decryption exploit involves a complicated process, but the heart of the issue is that Android devices powered by Qualcomm chips store their encryption keys in software rather than in hardware. Security researcher Gal Beniamini discovered several issues in the implementation of Android’s full disk encryption that would allow an attacker to decrypt an Android device with a Qualcomm chip. While Apple tightly controls its manufacturing, Android is on thousands of devices over which Google has little to no control. iPhone is essentially just one device (okay, maybe a dozen devices if you want to count every 5s, 6 and 6 Plus as unique). Those devices are in turn made up of lots of different components from manufacturers of chips, cameras and other hardware.Īndroid frequently gets compared to its largest competitor, the iPhone, but the comparison is a bit sticky. Supply-chain complexĪndroid is an open-source platform, so lots of smartphone manufacturers are building devices to run Android. But to understand why users didn’t get their hands on a fix until May, you have to understand a little bit about the complex supply chain that goes into Android devices and Android’s approach to securing its massive ecosystem. With so much national focus on strong encryption, the year-long delay seems like a glaring problem. The FCC cited the Stagefright bug in Android as one of the security vulnerabilities that inspired the investigations.

The patches came as the Federal Trade Commission and the Federal Communications Commission announced parallel investigations into the pace at which Google and other smartphone makers roll out security updates. This diverse supply chain is what led to the exploit used to break Android’s full disk encryption.
