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. 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 make this attack better, the DoublePulsar exe should really be patched with some proper code and incorporated back into the master Github repo, but that will have to wait for now.

Regardless, it looks like work is underway to port the attack over to x86 in Metasploit anyways, so once that happens it will be much easier to attack most Windows-based embedded devices. Please share this post if you found it useful and reach out if you have any feedback or questions!

You might not know how at-risk your security posture is until somebody breaks in. Don't let small fractures in your security protocols lead to a breach.

I will avoid memory leak. Dangerous operation: attempt to control one transaction. Below operation is dangerous. NSA eternalromance modify transaction RefCount to keep controlled and reuse transaction after leaking info. This is easy to to but the modified transaction will never be freed. The next exploit attempt might be harder. I will avoid it. From a picture above, now we can only control trans2 by trans1 data.

Also we know only offset of these two. After reading memory by modifying and completing trans2, trans2 cannot be used anymore.

To be able to use trans1 after trans2 is gone, we need to modify trans1 to be able to modify itself. To be able to modify trans1 struct, we need to use trans2 param or data but write backward. On 32 bit target, we can write to any address if parameter count is 0xffffffff. On 64 bit target, modifying paramter count is not enough because address size is 64 bit. Because our transactions. To be able to write backward with offset only,. InParameters pointer before leaking next transaction.

InParameter is still 0xffffffff. Modifying token seems to be difficult. 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.

So when running eternalblue against a server R2 target the associated risks, fall more in line with running any other exploit. As you can see it completes successfully against the server R2 and it results in CMD access to the device.

If you look at the above configuration, no payload was configured, resulting in the default payload been used. Thats not meterpreter, so how do you get a meterpreter shell? This will show you all the running processes. To migrate into the winlogon. The windows command systeminfo will reveal what the servers function is under the OS Configuration option, see directly below. You could just run hashdump which you can see the result of directly below.

I have cracked my lab DC hashes over and over, as such they are in the john pot file and it will no longer reveal the password unless you specify it to do so, to specify that it does reveal previously reversed passwords use the —show switch. Easy to follow. No jargon. Pictures helped. Didn't match my screen. Incorrect instructions. Too technical. Not enough information. Not enough pictures. Any additional feedback? Submit feedback. Thank you for your feedback! Security update file names.
