It sure has been a long time since I last wrote anything here, so I remembered there was a blog that is either dead or is about to die :)
Anyway, just wanted to say “hi” to everyone out there and let them know the blog is not dead, I will be sharing some of the work I have been doing, as soon as I can. For now, just wanted to share a couple of documents for those interested in working on HDFS. Continue reading
Hola,
I know it seems that the zone has been abandoned for a year, and that is why I didn’t want the year to end without posting anything. Anyway, this presentation has been covered in Feb-2016, and thought why not share it with the DFIR community, maybe it will be useful to someone out there.
Presentation title: Anti-Forensics: Leveraging OS and File System Artifacts.
It doesn’t cover all the anti stuff, but it is a good start.
Enjoy…
The Case:
A company’s web server has been breached through their website. Our team arrived just in time to take a forensic image of the running system and its memory for further analysis. The files can be found below:
1- System Image: here
2- System Memory: here
3- Hashes: here
4- Passwords = DFChallenge@s4a

I tried to help by giving ideas, but it seems they didn’t help solve the case! So I said to myself why not replicate the process and do some checks!
Actions below done not in exact listed order (more later)!!!
1- Started a cmd.exe with Administration priveleges, and executed:
net user cmduser cmduser /add
2- From the Windows Control Panel and using the User Account applet, I added a user named guiuser.
Now; the first idea I had in mind is I thought that checking the system logs alone was enough to find clues about the exact location of execution & creation. I was wrong about that! Both log entries showed no difference at all except the username for sure :)
