The ransomware can simply encrypt the already-encrypted data once again, with its own key this time. In principle, BitLocker cannot protect you from ransomware – on the contrary, it could be abused by ransomware to lock your data from yourself.
Does ransomware work on BitLocker?
If the PC does not have a ‘data partition’ other than the operating system partition, the malware is able to create (and encrypt with BitLocker) a file containing a virtual partition (VHD) and move all the user’s documents into this ‘virtual partition’ (this is referred to as ‘VHD Locker Ransomware’).
Can BitLocker To Go be hacked?
Most internet sites will tell you that it’s not possible to get access to the data on a hard drive that is encrypted with Bitlocker, but this is not true. In December 2021 we developed a process that allows us to hack the security of Bitlocker encrypted hard drives and get access to the decrypted data.
Does encryption a drive protect against ransomware?
No one solution available in the market today can completely protect against ransomware, but data encryption is key to any comprehensive data protection strategy. Data encryption software affords control over security policies that prevent malicious users and rogue processes from taking control of your sensitive data.
What does BitLocker protect against?
BitLocker (and BitLocker To Go) is a whole-disk encryption program that encrypts data on a Windows PC or USB flash drive to prevent unauthorized access from anyone that does not have the decryption key or user’s account credentials.
How safe is BitLocker without TPM?
BitLocker, even without a TPM, provides a reasonable level of security, but only if the user is careful. Don’t carry the USB key around in the same bag as the computer (or permanently plugged into the computer). That defeats the whole point of having it. At the same time, don’t lose the key.
Can ransomware be detected?
Detection By Abnormal Traffic
Monitoring file operations is an endpoint-level form of behavior-based threat detection. However, ransomware can also be detected at the network level by looking for anomalous traffic that may indicate a ransomware infection or malware in general.
How long does it take to crack BitLocker?
Assuming we could somehow process 500 trillion passwords an hour (which would be 3,623 times more than the ~138 billion passwords per hour capability of a desktop computer in 2008 under 10% load), it would still take us ~7.7 x 10^19 years to brute force crack this 48 character numerical recovery password.

What happens if I delete my BitLocker recovery key?
If you use Bitlocker encryption, you need to have either a password or a key to restore the file. If you have deleted the Bitlocker key, you must find the backup key to unlock the file. If the key is not found, the encrypted file basically cannot be opened. This is how to find Bitlocker recovery key in Windows.
Can ransomware spread through flash drive?
Anyone bringing a USB stick to the office is now a possible ransomware infection vector. Simply navigating through the folders on your system or desktop using double-click will execute the worm. Using this strategy, it will not only spread to USB thumb drives, it will also encrypt newly created files on the system.
How long does it take for ransomware to encrypt your files?

BitLocker monitors the system for changes to the boot configuration. When BitLocker sees a new device in the boot list or an attached external storage device, it prompts you for the key for security reasons. This is normal behavior.
Does BitLocker need TPM?
BitLocker normally requires a Trusted Platform Module, or TPM, on your computer’s motherboard. This chip generates and stores the actual encryption keys. It can automatically unlock your PC’s drive when it boots so you can sign in just by typing your Windows login password.
Can TPM 2.0 Be Hacked?
Can the attacker use it to hack your network? Research published last week shows that the answer is a resounding “yes.” Not only that, but a hacker who has done her homework needs a surprisingly short stretch of time alone with the machine to carry out the attack.
Is BitLocker tied to the motherboard?
Bitlocker makes use of TPM that’s embedded to motherboard so you don’t need to unlock a Bitlocker encrypted drive during boot. When a motherboard is replaced, the unlock key no longer exists, so you will be prompted to enter a recovery key. Therefore, you will want to make sure you have a backup Bitlocker recovery key.

The BIOS password does not have any effect on DMA attacks. The BitLocker pre-boot PIN can assist in mitigating a specific type of DMA attack called “early DMA”, which is carried out before the IOMMU is initialized and ready to restrict memory access from devices. See here for more detailed information.
What happens if you pay ransomware?
