kkamagui / bitleaker Goto Github PK

I am attempting to recover my personal data. I first used napper, which reports my system is vulnerable. However when I run bitleaker, I get the following "Get PCR data from bitleaker driver.. Fail". Does the bitleaker driver support sha1 pcr data, and is it possible to recover my data using bitleaker?

The targeted disk has 5 partitions

sda4 should be the primary system drive for Windows.

When I ran bitleaker.py, the program runs normally but ends with an error :

BitLeaker: Error. /dev/sda3 is not BitLocker-locked partition

Hi
Napper working and get pcr vulnerable
Why in bitleaker fail.
And how change drive like /dev/sda3
To /dev/sda5
Sda3 is no lock
Sda5 have bitlock

When trying to run bootstrap, it attempts this step:

git clone https://github.com/kkamagui/bitleaker-grub.git

However, that repository doesn't seem to be published yet. Are you planning on releasing that?

Hi, I'm trying to recover my data from my Dell Latitude 5511 laptop, as I cannot recover the recovery key since I've never activated bitlocker.
I found your amazing project and I thought perhaps I have a chance to get back my data.
I run Napper 1.3 live cd but after starting Napper, it seems to stack with no progress at the "Napper 1.3 is stacking without no results at the "Reading PCR values of TPM and checking a vulnerability ..." , I noted that there is an error, I will add a picture to let you understand better my problem

Can you please help me?

Hi,

I checked the device with napper (and it said the device is vulnerable). I installed an Ubuntu 18.04 on an USB stick and build the bitleaker tool.
When i start the stick, it says that the uefi event log cannot be read due to invalid parameters. On another machine, grub can read the event log, but the device is not vulnerable. The differences of the two devices is, that the vulnerable device uses an Intel fTPM and the other a dTPM.
Has anyone a clue, where the error is? I changed nothing.

Hi. I was asking before about V1 code. I modified your code to use either the V1 or the V2 code depending on which key you press at boot time. I've been working on trying to get the script to work. I've been able to get most of the pieces, but I wanted to find out if there was a SHA1 that needed to be used for the signature? I've checked a few things (I monitored the LPC bus, and checked against the data you recovered). And I still seem to be missing something, as I get all the way to the Unseal command and it fails. I can't give you direct logs or anything now because I don't have the system available. Unfortunately, I don't have a compiler handy to compile PCRTool, which I believe would be helpful, but I can't find an executable, just source code (I can't compile on my target. No compiler). Also, it seems that there might be more things sent to the TPM than got logged. Maybe there is another way to check this Windows TPM logs?

This isn't really a bug, but there didn't seem like a better place to put this.

I was wondering if bitleaker has some kind of log for when you are attempting to boot windows to discover what the TPM messaging looks like? If so, how can I activate it? If not, do you have any ideas on how to implement one? I don't know what kind of logging grub already has available. My current quick approach would be a video camera I guess.

Hi, I am also trying to run napper (liveCD) to check vulnerability.
Unfortunately it stucks at the Stage "Reading PCR values of TPM and checking a vulnerability".
I also run resourcemgr and tpm2_listpcrs.
Will try to attach logs.

what could have gone wrong? Notebook Futjitsu.

Any chance to fix this error (newest ubuntu):

Everything appears to be working beautifully but the data seems to be a lot shorter than the other logs I have seen which is causing it to fail. The unit is a NUC using Intel PTT

Any ideas would be greatly appreciated

Hi There,

I wonder if you can help.

I'm trying to mount a Windows 10 partition that is currently locked by TPM. (TPM with Secure Boot ON appears to unlock the drive and try to boot the Windows partition).

Bitleaker appears to be my last hope.

When running this tool on a USB setup of Ubuntu 18.04.6 LTS (in UEFI mode) I get the below results:

I currently have Secure Boot disabled i the BIOS to allow me to get to this stage.

I did notice it's showing PCR 0 at the start though?

Great job!!!!
Maybe you are planning to release a ready bitleaker USB version (.iso) ? I want to test this on my system.
Or maybe you can give some advice how can I do it myself (how to create a bootable bitleaker USB).

Thank you!

Is it possible to integrate Bitleaker into Kali Linux ISO?
I ran ./bootstrap in Cubic, but Build BitLeaker kernel module failed:

For checking the S3 sleep feature of the system, it's needed to find "[deep]" string from /sys/power/mem_sleep like below.

$> cat /sys/power/mem_sleep
s2idle [deep]

Thank you for @roboknight.

Failed at getting PCR data from BitLeaker driver. No more details directly available. Is this error code common?
I was able to get some PCR output from napper-for-tpm, but no success with bitleaker.

I'm having a somewhat similar problem to #9. I'm attaching my bitleaker log: log.txt

I'm fairly new to TPM, so I've been trying to understand what is happening. As far as I can tell, bitleaker reads a binary blob from dislocker, and that is supposed to contain 220 bytes of the priv/pub object, and the rest is something else.

Here is the snippet that dislocker is returning:

The private portion is 0xaa bytes long. So the public portion should start at 0xac. The size of the public portion is then 0x4e, and so it should end at 0xae + 0x4e = 0xfc. But 0xfc > 0xdc == 220. So it seems like maybe my keys are 0x20 bytes larger than usual, and bitleaker is truncating them, which causes the TPM2_Load to fail?

I am not sure if it is relevant, but I have SecureBoot disabled, and I am running Windows 11.

I'll try to change 220 to 0xfc in bitleaker.py and see if that fixes the TPM error.
