Hack Filevault 2
So here’s a tip for you: to quickly solve some of the issues mentioned in this article. But to help you do it all by yourself, we’ve gathered our best ideas and solutions below.FileVault is one of those Mac features that you know is there but are never really sure what it’s there for. Apple has never really made a big song and dance about how the feature protects your data or why you should bother with it, so we’re going to do it instead.This won’t be a literal song and dance, unfortunately, (we don’t have the natural rhythm) but we will tell you all you need to know about FileVault, as well as how and why you should use it. But feel free to sing the words as you read them and dance along at the same time.Okay, let’s get into it. What is FileVault?FileVault is macOS’s built-in disk encryption feature.

It's designed to encrypt your Mac's hard drive and all of the files located on the drive using 128-bit AES encryption with a 256-bit key.Once FileVault is enabled on your Mac, all existing data will be encrypted. From then on, any new and changed data will be automatically locked down and password protected on boot to prevent unauthorized access.FileVault was originally introduced to Mac back in 2003 on OS X 10.3 Panther.
But to say it wasn’t very good would be an understatement. It was terrible. The functionality was poor, the implementation was shoddy, and only the home directory could be encrypted.Thankfully, 2003 was a long time ago and now, with FileVault 2, you can expect full-disk encryption and the ability to use the Find My Mac feature to wipe your drive remotely if ever your system falls into suspect hands.

Should I use FileVault?Yes, is the short answer.If you’re concerned about the privacy of your files and user data, and your computer contains information that shouldn’t be seen without authorized access, you should absolutely use FileVault disk encryption.The feature is particularly good if you’re a MacBook user that regularly takes your laptop on the move where there’s a greater chance of it becoming lost or misplaced.FileVault offers peace of mind and that counts for a lot. There are, however, reasons why you might not want to bother with the feature.First of all, FileVault enforces a password. If you struggle to remember passwords (it’s well worth using a password manager if you do) or prefer using your Mac without one, you might consider FileVault to be more effort than it’s worth.Secondly, FileVault encryption is backed into the CPU which can affect performance.
If you own a newer SSD-equipped Mac you’re unlikely to notice the difference, but in older Macs with HDDs performance can take a significant hit — enough for you to consider using your computer without encryption. How to check if FileVault is enabled?In systems running OS X Yosemite 10.10 and newer, Apple encourages you to turn on FileVault 2 during setup. So, if you’re using a newer Mac, there’s every chance that your files are already being encrypted.Here’s how to check:. Click on the Apple menu and select System Preferences. Select Privacy & Security. Click on the FileVault tab and the status will be displayed.Before you turn on FileVault, be aware that the initial encryption process can take hours. However, it does run in the background so you can continue using your Mac as normal, albeit not at peak levels of performance.Also, FileVault encrypts the entire disk.
Any additional users will need to be enabled so that they can unlock the disk by entering their password.

Cryptology researchers have analyzed Apple’s FileVault 2 volume encryption technology and determined that, with a secure password, it would take up to 34 years to break with a brute-force attack, (PDF) announced. The findings came as part of a successful attempt to create an independent method of decrypting an encrypted volume without using Apple’s decryption technique.The researchers found that FileVault 2 on its own is relatively secure compared to competing encryption techniques. Assuming a strong password, it would take up to 2 30 seconds, or 34 years to break into a FileVault encrypted volume with a brute force attack.However, the security of the encrypted volume is only as good as the password used to protect it.

Assuming a six character common word password, FileVault 2 can be breached in as little as 5.6 hours.In addition to testing FileVault’s efficacy, the researchers successfully created a new method of decrypting a FileVault-encrypted volume without employing Apple’s proprietary decryption method. This new method requires access to the user’s password or FileVault recovery token, and so does not by itself pose a security threat, but it may lay the groundwork for further deconstruction of Apple’s encryption method and could eventually lead to a FileVault security breach.The researchers were able to circumvent FileVault’s own decryption scheme due to the fact that, in order for the volume to be decrypted, some information on the disk must remain separate from the encrypted volume to serve as the key for unlocking the data. This separate key is unlocked with a user password and then goes on to unlock the volume.Using an algorithm to derive the decryption key, the researchers successfully decrypted the volume without using Apple’s FileVault process.
As mentioned above, the user password or FileVault recovery password (which is generated when a user activates FileVault for the first time) is still required to complete the decryptionNow that researchers no longer need Apple’s FileVault decryption scheme, however, FileVault encrypted volumes can be accessed from other computers—such as those of a hacker or forensic scientist—and potentially decrypted. Further, the method developed here may lead to advancements in which the user password is not needed at all for decryption.This recent FileVault research is separate from by password recovery company Passware. Passware was able to break FileVault’s security by performing an analysis of a Mac via a FireWire or Thunderbolt connection and obtaining the decryption keys from system memory.While the Passware breach was important for the security of all FileVault users, it was only possible if the attacker had physical access to the Mac and the user had already logged in. From there the decryption key, which is stored in memory so that it can decrypt files as needed, could be copied, a scenario that is unlikely for those Mac users who have automatic login disabled.FileVault 2 has proven itself to be safer and more effective than its predecessor, which only encrypted the user’s home folder, but no encryption can remain completely secure indefinitely.via Shutterstock.
