Windows 10 SSTP with self-signed certificates

I can’t seem to get the Windows 10 sstp client to connect to the (router) sstp server

I have tried numerous combinations when creating my self signed certificates (ca & server) but I have to admit that I’m a little stumped

CA : + Server : +

Windows 10 : +

Q1) When installing the certificate in Windows I usually select [Local Computer] certificate store rather than [current user]. Is it normal for Windows to also install a copy in the [current user] store ? If so what is the point of this duplicate certificate installation ?

Q2) When installing the certificate into the “Trusted Root Certificate Authorities” for [current user] I obtain the following warning : – why don’t I get this same warning when installing via [Local Computer] ?

Q3) What is the meaning of the yellow triangle with exclamation mark on both [Basic Constraints] and [Key Usage] ? +

Q4) Why doesn’t the SSTP client ( detect the presence of the previously installed (sstp server’s ca) certificate ?

Q5) I feel like my multiple certificate installation attempts may have ‘polluted’ my Windows’ certificate store. Is this possible ? If so is there a way to ‘clean up’ the certificate store (besides manually deleting unwanted certificates) ?

Q6) I believe that this used to work with Windows 10 before but, maybe because of the regular updates, things seem to have changed ?

Using Windows Registry and File Forensic Locations in Investigations

There are a number of forensically-useful areas in the Windows registry and file system like those detailed in this SANS Poster. I’ve found this data can be really useful when I’m conducting investigations.

I was curious about how much others take advantage of this data.

  1. Do you use the data found in those locations as part of your investigations?
  2. What tool(s) do you use to extract the data from those locations?
  3. What tool(s) do you use to visualize/interact with the data you’ve extracted?
  4. Do you bring that data you’ve extracted into your SIEM?
  5. Do you use any dashboards/add-ons/apps within your SIEM to interact with that data?

understanding an integer overflow under windows 10

I did this test case that checks for the lens of contents, and based on what I was researching on the internet it says from -128 to 127 the length range, but the code was compiled under visual studio 2019 with the following: /GS , /dynamicbase , however, the proof of concepts is below. once I got executed the POC of concept in order to overwrite EIP / seh chains. I got __report_gsfailure which is where it detects the overflow. i am trying to overwrite the seh chains in order to get code execution. I also tried to overwrite seh chains eb 0 pointing to a non safeseh , but it doesnt work either

exp poc

junk = "A" * 1000  nseh = struct.pack('<I', 0x42424242) #struct.pack('<I',0x90906eb) #struct.pack('<I', 0x42424242)  seh = struct.pack("<I", 0x43434343) # 320 nseh # 316 seh  payload = junk #+ nseh + seh

Any tool to help disable Windows defender? by creating a file to send to the victim VM and test? [closed]

I am using two VMs on my computer , A Kali Linux, and a Windows 10 machine.

I was able to exploit the windows machine without any problem. however I had to disable windows defender first.

I was wondering if there is any tool in Linux Kali that can either remotely disable windows defender, or I can create a file that then move to the windows machine and execute to disable windows defender to simulate a real life scenario.

Thank you!!

Windows 10 version 1809, not offered an upgrade to 1909 in Windows update

My Windows 10 build version is 1809. When I go into Windows update it does not offer to upgrade me to 1909 which should be the most recent as of today.

I notice that there is a bad bug (source: in 1909 which is patched by KB4551762 (, but I don’t get it on my build.

So does this mean 1809 is not vulnerable to the SMBv3 ‘wormable’ issue? ANd why don’t I get the newest version of Windows?

SSD not working anymore and windows not opening [migrated]

I’m struggling with a problem: the Windows suddenly stopped working when I connected the HDD with rack on my laptop. I’ve tried almost everything, so later on I have discovered after re-installing the HDD, and place the SSD in the rack that SSD is not initialized and also, is 100% free. After that, I tried to recover the files from the SSD because I’ve lost sensitive information and a lot of photos from the past years… nothing worked, What happened and what solutions do you think I have? Is the SSD broken somehow? EDIT: Last error when I`m trying to initialize enter image description here

Destroy cluster windows server 2012 r2

I want know how to delete a Windows Server Failover Cluster. My case is a bit special.

I encountered some problems while creating a failover cluster, and I stopped the cluster services then I did “evict nodes”, then “destroy cluster”.

Then the cluster disappears and now I can no longer recreate a cluster because it tells me that the servers are in a cluster. In this case how to delete a cluster which is not visible in server manager?

It’s for SQL Server high availability.
