How To Crack Android Full Disk Encryption Qualcomm Device

The hit fight amongst Apple and the FBI incited a ton of discuss Encryption – the innovation that has been utilized to keep every one of your bits and bytes as protected as could reasonably be expected.

We can not say a ton in regards to Apple's clients, but rather Android clients are at extreme danger with regards to encryption of their own and touchy information.

Android's full-circle encryption can be broken considerably more effectively than anticipated with animal power assault and some persistence, influencing possibly countless cell phones.
Google started implementing Full Disk Encryption on Android by default with Android 5.0 Lollipop. Full disk encryption (FDE) can prevent both hackers and even powerful law enforcement agencies from gaining unauthorized access to device's data.
Android's disk encryption, in short, is the process of encoding all user's data on an Android device before ever written to disk using user's authentication code. Once encrypted, the data is decrypted only if the user enters his/her password.
However, after thoroughly analyzing Android's full disk encryption implementation, a security researcher came to the conclusion that the feature is not as secure as the company claims it is, and he has a working code to prove it.

Cracking Android Full Disk Encryption: Exploit Available Online

Security analyst Gal Beniamini has found issues (CVE-2015-6639 and CVE-2016-2431) in how Android gadgets handle its full circle encryption, making it less demanding for aggressors to access the client's delicate information. 

Beniamini likewise distributed a definite orderly guide this week on how one can separate the encryption insurances on Android cell phones controlled by Qualcomm Snapdragon processors. 

You can locate the full wellspring of the adventure on GitHub.

Basically, Android's disk encryption on devices with Qualcomm chips based only on your password. However, in real, Android uses your password to create a strong 2048-bit RSA key (KeyMaster) derived from it instead.
Qualcomm runs in the Snapdragon TrustZone to protect critical functions like encryption and biometric scanning, but Beniamini discovered that it is possible to exploit an Android security flaw to extract the keys from TrustZone.
Qualcomm runs a small kernel in TrustZone to offer a Trusted Execution Environment known as QSEE (Qualcomm Secure Execution Environment) that allows small apps to run inside of QSEE away from the main Android operating system. KeyMaster is also a QSEE app.
The researcher has detailed how attackers can exploit an Android kernel security flaw to load their own version of QSEE app inside this secure environment, thereby exploiting privilege escalation flaw and hijacking of the complete QSEE space, including the keys generated for full disk encryption.
Once getting hold of this key, an attacker could perform a brute-force attack to grab the user password, PIN or lock, cracking Android's full disk encryption.
Moreover, Qualcomm or OEMs can comply with government or law enforcement agencies to break the FDE.
"Since the key is available to TrustZone, Qualcomm, and OEMs [Original Equipment Manufacturers] could simply create and sign a TrustZone image which extracts the KeyMaster keys and flash it to the target device," Beniamini wrote. "This would allow law enforcement to easily brute force the FDE password off the device using the leaked keys."
Beniamini has provided all the technical bits of the analysis on this blog, so you can go through this blog if you are interested in having highly technical details on the issue with Android's FDE.
Although Beniamini is working with both Qualcomm as well as Google, the core of the issue might not be completely fixable and might even require new hardware changes to fix.
