QUESTION
I use a TPM 2.0 with verified and measured boot. Now I read about external TPM modules for mainboards, which do not have a TPM module yet. I am a bit confused on how secure this is. I think a attack vector could look like this:
- Put a man-in-the-middle device between mainboard and TPM which records every data sent
This way an attacker could exfiltrate e.g. windows bitlocker keys. Are there any methods to prevent such attacks? I am also interested about the security about TPM modules on motherboards, since there the same attack could be done. How is the firmware measured into the TPM? Does this rely on data from the TPM?
...ANSWER
Answered 2021-Nov-04 at 17:04Yes such man-in-the-middle attacks against the TPM are well-known; articles describing them seem to come out with regularity, almost on an annual basis (see here for the latest one).
The way to protect against them is session-based encryption. (see section 21 here)
To present the simplest use case, where the session is not an authorization session and is not bound to a TPM object: basically, you would start a salted session, which will ensure that only you and the TPM have access to the salt. Interception of the session start message would not help, as the salt is encrypted with a TPM key.
Then the session key is computed:
QUESTION
I try to set Creation, Write and Access time for all files in a directory. And that works if file is on local machine. But when I try to do it for directory on a removable disk, I get an exception:
System.IO.IOException: 'The parameter is incorrect. : '*path*'
I really don't know why it happens, but:
- the path is correct
- BitLocker is turned off
- files don't have a read-only attribute
ANSWER

I am in need of help regarding powershell command - Enable-Bitlocker
The following code is an example:
...ANSWER
Answered 2021-Mar-04 at 12:58I managed to solve my own problem after reading the microsoft documentation of bitlocker a little bit more thoroughly.
It seems i have done every step required to automate the process , but in order to receive a recovery key , we need to add a recovery password protector (do note that adding a recovery password protector does not require us to actually submit a password but only to receive a recovery password and a numerical password) The process of receiving the password is achieved by invoking the following command with powershell.
QUESTION
I am trying to create a report using Microsoft SQL Server Management Studio 2012. I've got a fair amount of experience writing SQL reports, but have never had to use what I think should be a PIVOT until now.
Our RMM - Kaseya, uses the same column for all "custom audit fields", we have made a few custom "columns" like: SMART Drive Model, SMART Status, and SMART Last Updated date. You'd think these are defined as their own columns, but no -- regular entries in a cell, linked to an agentguid.
From looking at the table below, the fieldValue on the right is dependent on the fieldName to the left of it. I'm not sure how to turn these rows into their own columns based on the fieldName.
I'm seeking a query that produces five columns:
- agentguid
- Model
- Size
- Updated
- Status
I will later run an INNER JOIN on this data, to compare against the agentguid and be able to customize my final report.
Below is a sample of data
...ANSWER

agentguid,
MAX(CASE WHEN fieldName = 'SMART Drive Model' THEN fieldValue END) AS Model,

MAX(CASE WHEN fieldName = 'SMART Updated' THEN fieldValue END) AS Updated,
MAX(CASE WHEN fieldName = 'SMART Status' THEN fieldValue END) AS Status

QUESTION
Cannot seem to get GraphAPI to query Bitlocker Recovery Keys out of PowerShell. Using an Azure AD App registration
...ANSWER
Answered 2020-Nov-19 at 06:03For this problem, the error was caused by incorrect grant type(grant flow). As we can see the document shows us this graph api requires Delegated permission BitLocker.ReadBasic.All, BitLocker.Read.All
, and it doesn't support "Application" permission.
So we can't use client credential flow to get the access token, we need to use username/password flow to do it. Please refer to my test in below screenshot.
After running the command, we can see the result don't show the error message.

QUESTION
I'm developing a computerCheck program, it's Python based (for now). The programs basically checks some Windows OS status, e.g. if the correct AV is running, if bitlocker is activated and so on.... The result of the check OK or NOT OK is reported into the database. However, since it's about 10 checks...I would like to report in a smart way back to the database. I don't want to have an entry for every check in the record, because this would be a problem when the number of checks change. So I would like to send a "smart" kind of checksum... The checksum should give which of the checks are NOT OK (e.g. check nr.1 is false, check nr.4 is false) and preferable a reason...like nr 1. status 2 (2 represents e.g. service not running..)
Now, the big question is, is it possible to do it that way, so e.g. always sending a x character long code to the database and when reading the code back, you can "unpack" it to something human readible again....
I hope it's clear what I'm looking for...
Thanks in advance! /Jasper
...ANSWER
Answered 2020-Sep-03 at 10:35You could create a string where every index represents one check. You will have more than enough chars to use as states. For example:
"0120"
-> check0 ok, check1 error state 1, check2 error state 2...
New checks can simply be appended to the string, removed checks need to be marked as no more existent:
"0X200"
-> check1 doesn't exist anymore and one new check appended at the end.
QUESTION
I wrote a program that will close the hard drive with BitLocker in Windows by using libraries datetime
and subprocess
but I cannot get the correct result.
Here is my code:
...ANSWER
Answered 2020-Jun-27 at 16:16That is because you are checking the current time now = datetime.datetime.today()
, then add 2 hours to it and immediately after check, if time_delta
is equal to now
.
Thus the if statement always results in false and the code in it does not get executed.
You need to put something in place to wait. Something like that.

Install bitlocker
You can use bitlocker like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
