Now I can happily talk for ages on security, but this, writing a blog, I felt stuck, so why? In fact, just to prove this, there is a recording of me saying this very statement Enemies of the West — Neil Lines — Bsides London in front of a few hundred people at Bsides London.
If all goes to plan and this is a very big if , there is no requirement for any other typical pentesting tools or techniques. I like to earn it, but we can no longer bury our heads in the sand and I can no longer ignore MS Now anyone can use it you could even teach your Nan to do this , but without a little respect, or understanding, you will most likely reboot your target.
So what is a Domain Controller? Think of it as the most important server in a windows environment. Typically, people have multiple DCs and these multiple servers replicate the contained data, this offers resilience and load balancing. To summarize, DNS is offered as a service during active directory creation.
To do this, I look for any devices that offer DNS as a service. Below shows the full results of a typical Nmap scan of the suspected DC. The inclusion of the open ldap, kpasswd5, http-rpc-epmap, ldapssl and globalcatLDAP ports, are also typically connected to a DC server.
To do this quickly, you can use MSF or Nmap. The following quick overview shows operating system enumeration using both of these tools. You can also use the -O Enable OS detection switch, the results of using this can be seen directly below.
Alternatively, you can use -A to also enable OS detection, again the results of using this switch can be seen directly below. From the above results you can see two potential hosts Windows 7 Enterprise and Windows Server R2 which are potentially vulnerable to MS If you have seen the above failed response before in MSF, you have most likely caused the target machine to reboot. Windows 7 was released offering users a 32bit and 64bit version, the 32 bit was the most commonly installed, and as such, I personally would not target a windows 7 machine.
At this point, I figured my best option would be to make the original DoublePulsar implant work for my needs instead of trying to reverse engineer everything and create my own attack from scratch.
I will not go in-depth into the background of these commands, since the two posts I linked to above already do a great job of explaining the setup process. The initial attack is executed from the Win7 attack box using the EternalBlue attack within the Fuzzbunch framework with minimal deviations from the defaults:.
We can see the string at 0x :. Double-clicking on the string will bring it up in the. Right-clicking and choosing Graph view will provide a better idea of the flow of this routine. This gives us a graph that looks very promising for something like an OS version checking routine.
Notice the section that we jumped to is in the bottom right corner of this graph, so we can traverse upwards to see how we got here. A few levels up, we find the Windows 7 check. So the easiest thing to do here is just simply change the jz to a jnz. It looks like jz is 74 and jnz is Note it starts with the 74 opcode that we expected. Simply changing that to 75 will switch the path the program takes to kick this down the Win7 path.
Again, this is really hacky and a terrible shortcut but we can always come back and make a proper patch after verifying this works. Now we can see the updated jnz call. Permalink master.

MS exploit for Windows and later by sleepya. A transaction with empty setup:.
Note: method name is from NSA eternalromance. For Windows 7 and later, it is good to use matched pair method one is large pool and another one is fit. Additionally, the exploit does the information leak to check transactions. So this exploit should never crash a target against Windows 7 and later.
For Windows Vista and earlier, matched pair method is impossible because we cannot allocate transaction size. Only this transaction type uses this heap. Normally, no one uses this transaction type. So transactions alignment. The drawback. So this exploit has a chance to crash target same as NSA eternalromance against Windows Vista and earlier.
SrvImpersonateSecurityContext is used in Windows Vista and later before doing any operation as logged on user.
MS – The Nuke – red.
The next exploit attempt might be harder. This is my 1st blog post for red , so I wanted it to be good. Now that we have a listener setup on Kali, and a DLL ready to be injected that will make the victim call back to Kali, all we have left to do is actually inject the DLL using our modified version of DoublePulsar. To do this quickly, you can use MSF or Nmap. I was able to easily plant a backdoor using the EternalBlue tool, but the DoublePulsar implant was not developed with Windows Embedded 7 in mind and exploit attempts would throw an error upon execution:.

Thank you for your feedback! So follow that page to get those prereq patches on and then the patch will install. Monday, May 22, Following the massive Wana Decrypt0r ransomware outbreak from yesterday afternoon, Microsoft has released an out-of-bound patch for older operating systems to protect them against Wana Decrypt0r’s self-spreading mechanism.
These are old operating systems that Microsoft stopped supporting years before and did not receive a fix for the SMBv1 exploit that the Wana Decrypt0r ransomware used yesterday as a self-spreading mechanism. Microsoft had released a fix for that exploit a month before, in March, in security bulletin MS That security bulletin only included fixes for Windows Vista, Windows 7, Windows 8.
As the SMBv1 is a protocol that comes built-in with all Windows versions, the computers which did not receive MS remained vulnerable to exploitation via Wana Decrypt0r’s self-spreading package. While unconfirmed, many believe older Windows XP and Windows Server versions were the bulk of the infections pool, as they had no way to protect themselves.
