Using Nmap to find Local Admin

Using Nmap to find Local Admin

While conducting  penetration tests I almost always obtain user credentials; sometimes in cleartext, and other times just the hash. If your like me; you’ve often wondered, where do I have local Administrative privileges with these credentials.  If you haven’t checked out Joesph Pierini’s blog post here, I highly suggest you check it out before continuing.

I can’t even count the number of times I have had user credentials or a hash and wondered where I had Local Administrative privileges.  Sure I could fire up metasploit’s msfconsole and psexec across the network.  Hell I could even create a resource script to automate the entire task for me, but its doesn’t scale very well and often times the default metasploit config is not very stealth when you flag every workstation and server antivirus on the network.  That’s when I started to utilize Nmap’s smb-enum-shares NSE script.  I’ve been aware of the script for sometime now, but I wasn’t aware that you can feed it arguments such as a username, password, domain and others.  Even better, the NSE script doesn’t need cleartext credentials so you can pass-the-hash like we all love to do.  The syntax is pretty straightforward as seen below:Read More


Using Nmap to Screenshot Web Services Troubleshooting

Using Nmap to Screenshot Web Services Troubleshooting

Recently a member from the Trustwave SpiderLabs team created an nmap NSE script that could be used to take a screenshot of webpages as it scanned the network. Working for a top 10 accounting firm, I conduct a lot of internal penetration tests for clients that operate on very large networks, and sometimes I’m required to audit entire counties.  Having the ability to view all the webpages on the internal network without being required to manually type in each addresses into the browser sounded amazing.  This was very exciting news now that there was a way to automate this process and have the ability to scale.  I dove in right away to get started by installing the script based on the instructions in the link listed below:

I highly suggest you look over the article above as I wrote this article in hopes that it would help assist anyone when having issues getting the http-screenshot NSE script to function properly with the latest version of nmap.
