7MS #432: Tales of Internal Network Pentest Pwnage - Part 21

Yay! It's time for another tale of pentest pwnage! Highlights include:

  • Making sure you take multiple rounds of "dumps" to get all the delicious local admin creds.

  • Why lsassy is my new best friend.

  • I gave a try to using a Ubuntu box instead of Kali as my attacking system for this test. I had pretty good results. Here's my script to quickly give Ubuntu a Kali-like flair:

sudo apt-get update sudo apt-get upgrade -y sudo apt-get install openssh-server -y sudo apt-get install nmap curl dnsrecon git net-tools open-vm-tools-desktop python3.8 python3-pip unzip wget xsltproc -y #Aha helps take output from testssl.sh and make it nice and HTML-y sudo git clone https://github.com/theZiz/aha.git /opt/aha #Awesome-nmap-grep makes it easy to grep nmap exports for just the data you need! sudo git clone https://github.com/leonjza/awesome-nmap-grep.git /opt/awesome-nmap-grep #bpatty is...well...bpatty! sudo git clone https://github.com/braimee/bpatty.git /opt/bpatty #CrackMapExec is...awesome sudo mkdir /opt/cme cd /opt/cme sudo curl https://github.com/byt3bl33d3r/CrackMapExec/releases/download/v5.1.0dev/cme-ubuntu-latest.1.zip -L -o cme.zip sudo unzip cme.zip sudo chmod +x ./cme #eyewitness is a nice recon tool for putting some great visualization behind nmap scans sudo git clone https://github.com/FortyNorthSecurity/EyeWitness.git /opt/eyewitness cd /opt/eyewitness/Python/setup sudo ./setup.sh #impacket is "a collection of Python classes for working with network protocols" #I currently primarily use it for ntlmrelayx.py sudo git clone https://github.com/CoreSecurity/impacket.git /opt/impacket cd /opt/impacket sudo pip3 install . #mitm6 is a way to tinker with ip6 and get around some ip4-level protections sudo git clone https://github.com/fox-it/mitm6.git /opt/mitm6 cd /opt/mitm6 sudo pip3 install -r requirements.txt # install service-identity sudo pip3 install service-identity # lsassy sudo python3 -m pip install lsassy #nmap-bootstrap-xsl turns nmap scan output into pretty HTML sudo git clone https://github.com/honze-net/nmap-bootstrap-xsl.git /opt/nmap-bootstrap-xsl #netcreds "Sniffs sensitive data from interface or pcap" sudo git clone https://github.com/DanMcInerney/net-creds /opt/netcreds #PCCredz parses pcaps for sensitive data sudo git clone https://github.com/lgandx/PCredz /opt/pcredz #Powersploit is "a collection of Microsoft PowerShell modules that can be used to aid penetration testers during all phases of an assessment" sudo git clone https://github.com/PowerShellMafia/PowerSploit.git /opt/powersploit #PowerupSQL is a tool for discovering, enumerating and potentially pwning SQL servers! sudo git clone https://github.com/NetSPI/PowerUpSQL.git /opt/powerupsql #responder is awesome for LLMNR, NBT-NS and MDNS poisoning sudo git clone https://github.com/lgandx/Responder.git /opt/responder

7MS #648: First Impressions of Level.io

Hey friends, today I'm sharing my first (and non-sponsored) impressions of Level.io, a cool tool for managing Windows, Mac and Linux endpoints. It fits a nice little niche in our pentest dropbox deployments, it has an attractive price point and their support is fantastic.

7MS #646: Baby's First Incident Response with Velociraptor

7MS #646: Baby's First Incident Response with Velociraptor

Hey friends, today I'm putting my blue hat on and dipping my toes in incident response by way of playing with Velociraptor, a very cool (and free!) tool to find evil in your environment. Perhaps even better than the price tag, Velociraptor runs as a single binary you can deploy to spin up a server and then request endpoints to "phone home" to you by way of GPO scheduled task. The things I talk about in this episode and show in the YouTube stream are all based off of this awesome presentation from Eric Capuano, who also was kind enough to publish a handout to accompany the presentation. And on a personal note, I wanted to share that Velociraptor has got me interested in jumping face first into some tough APT labs provided by XINTRA. More to come on XINTRA's offering, but so far I'm very impressed!

7MS #644: Tales of Pentest Pwnage – Part 64

Hey! I'm speaking in Wanatchee, Washington next week at the NCESD conference about 7 ways to panic a pentester! Today's tale of pentest pwnage is a great reminder to enumerate, enumerate, enumerate! It also emphases that cracking NETLM/NETNTLMv1 isn't super easy to remember the steps for (at least for me) but this crack.sh article makes it a bit easier!
