7MS #532: Tales of Pentest Pwnage - Part 39

Hey friends, wow...we're up to thirty-nine episodes of pwnage? Should we make a cake when we hit the big 4-0?! Anyway, today's TLDL is this: If you get a nagging suspicion about something you find during enumeration, make sure to either come back to it later, or exhaust the path right away so you don't miss something! Because I did :-/ A tip that's been helping me speed along my use of CrackMapExec and other tools is by using Kerberos authentication. You can grab a ticket for your test A...

7MS #531: Interview with Christopher Fielder and Eugene Grant of Arctic Wolf

Today we're joined by some of our friends at Arctic Wolf - Eugene Grant and Christopher Fielder - to talk about compliance. Now hold on - don't leave yet! I know for many folks, compliance makes them want to bleach their eyeballs. But compliance is super important - especially because it is not the same as being secure. So we discuss the differences between security and compliance, and practical work we can do to actually be more compliant and secure, including: Knowing what you have (asset...

7MS #530: Tales of Pentest Pwnage - Part 38

Hey friends, we have another fun tale of pwnage for you today. I loved this one because I got to learn some new tools I hadn't used before, such as: Get-InternalSubnets.ps1 - for getting internal subnets Adalanche for grabbing Active Directory info (similar to SharpHound) This tool worked well for me with this syntax: adalanche-windows-x64-v2022.5.19.exe collect activedirectory --domain victim.domain --port=389 --tlsmode=NoTLS Copernic Desktop Search for pillaging through shares ...

7MS #529: Interview with Matthew Warner of Blumira

Today we're featuring a great interview with Matthew Warner, CTO and co-founder of Blumira. You might remember Matt from such podcasts as this one) when Matt gave us a fountain of info on why out-of-the-box Windows logging isn't awesome, and how to get it turned up to 11! Today, we talk about a cool report that Blumira put out called 2022 Blumira's State of Detection & Response, and dive into some interesting topics within it, including: How do companies like Blumira (who we rely on to st...

7MS #528: Securing Your Family During and After a Disaster - Part 6

In today's episode, I try to get us thinking about our extended family's emergency/DR plan. Why? Because I recently had a close family member suffer a health scare, and it brought to light some questions we didn't have all the answers for: Do we have creds to log onto his computer? How about his email accounts? Do we have usernames/passwords for retirement accounts, bank accounts, etc.? For vehicles/ATVs/boats/etc. - do we have documentation about their service records? How about titl...

7MS #527: First Impressions of Purple Knight

In today's episode we talk about Purple Knight, a free tool to help assess your organization's Active Directory security. I stuck Purple Knight in our Light Pentest LITE pentest training lab and did an informal compare-and-contrast of its detection capabilities versus PingCastle, which we talked about in depth in episode #489. 

7MS #526: Tales of Pentest Pwnage - Part 37

Today's another fun tale of pentest pwnage - specifically focused on cracking a hash type I'd never paid much attention to before: cached domain credentials. I also learned that you can at least partially protect against this type of hash being captured by checking out this article, which has you set the following setting in GPO: Under Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > Security Options set Interactive logon: Number of previous logons...

7MS #525: First Impressions of InsightIDR - Part 2

Today we're sharing an updates to episode #512 where we ran Rapid7's InsightIDR through a bunch of attacks: Active Directory enumeration via SharpHound Password spraying through Rubeus Kerberoasting and ASREPRoasting via Rubeus Network protocol poisoning with Inveigh. Looking for a free way to detect protocol poisoning? Check out CanaryPi. Hash dumping using Impacket. I also talk about an interesting Twitter thread that discusses the detection of hash dumping. Pass-the-hash attacks wit...

7MS #524: How to Update VMWare ESXi From the Command Line

I'm extra psyched today, because today's episode (which is all about updating your VMWare ESXi version via command line) is complemented by video: https://www.youtube.com/watch?v=0-XAO32LEPY Shortly after recording this video, I found this awesome article which walks you through a different way to tackle these updates: List all upgrade profiles: esxcli software sources profile list --depot=https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml Grep for jus...

7MS #523: Local Administrator Password Solution - RELOADED!

Well friends, it has been a while since we talked about Microsoft's awesome Local Administrator Password Solution - specifically, the last time was way back in 2017! Lately I've been training some companies on how to install it by giving them a live walkthrough in our Light Pentest LITE lab, so I thought it would be a good time to write up a refreshed, down and dirty install guide. Here we go! (See the show notes for today's episode for more details!)

7MS #523: Local Administrartor Password Solution - RELOADED!

7MS #522: Pwning Wifi PSKs and PMKIDs with Bettercap - Part 2

Hey friends, a while back in episode #505 we talked about pwning wifi PSKs and PMKIDs with Bettercap. Today I'm revisiting that with even some more fun command line kung fu to help you zero in on just the networks you're interested in and filter out a bunch of noisy events from bettercap in the process.

7MS #521: Tales of Pentest Pwnage - Part 36

Hey friends! Today's another swell tale of pentest pwnage, and it's probably my favorite one yet (again)! This tale involves resource based constrained delegation, which is just jolly good evil fun! Here are my quick notes for pwning things using RBCD: # From non-domain joined machine, get a cmd.exe running in the context of a user with ownership rights over a victim system: runas /netonly /user:domain\some.user cmd.exe # Make new machine account: New-MachineAccount -MachineAccount EVIL7...

7MS #520: How to Succeed in Business Without Really Crying - Part 11

Hey friends, today we're giving another peek behind the curtain of what it's like to run a cybersecurity consultancy. Topics include: Setting the right communication cadence - and communication channels - with a customer during a pentest. Tips for collaborating well with contractors so that the customer experience feels like "a single human pane of glass" (insert barf emoji here). How we're using Intercom to publish self-help/FAQ articles for 7MS.

7MS #519: Tales of Pentest Pwnage - Part 35

7MS #518: Interview with Amanda Berlin of Blumira

Today we're pumped to share a featured interview with Amanda Berlin, Lead Incident Detection Engineer at Blumira. You might already be familiar with Amanda's awesome Defensive Security Handbook or fine work with Mental Health Hackers. We polled our Slack friends and structured this interview as an AAA (Ask Amanda Anything). That resulted in a really fun chat that covered many things technical and not technical! Questions we posed to Amanda include: Can you tell us more about your infosec su...

7MS #517: DIY Pentest Dropbox Tips - Part 6

Today we're continuing a series we haven't done in a while (click here to see the whole series) all about building and deploying pentest dropboxes for customers. Specifically, we cover: Auto installing Splashtop This can be done automatically by downloading your splashtop.exe install and issuing this command: splashtop.exe prevercheck /s /i confirm_d=0,hidewindow=1,notray=0,req_perm=0,sec_opt=2 Auto installing Ninite This can be done in a batch script like so: agent.msi /quiet ni...

7MS #516: Tips to Travel More Securely

In today's episode I talk about a cool self-defense class I took a while ago which was all about less lethal methods of protecting/defending yourself. I also talk about some safer ways to handle/hide cash while traveling on vacation.

7MS #515: Securing Your Family During and After a Disaster - Part 5

Today we continue the series we started a few years ago called Security Your Family During and After a Disaster (the last part in this series was from a few years ago. In today's episode we focus on some additional things you should be thinking about to strengthen the "in case of emergency" document you share with your close friends and family.

7MS #514: Tales of Pentest Pwnage - Part 34

Welcome to another fun tale of pentest pwnage! This one isn't a telling of one single pentest, but a collection of helpful tips and tricks I've been using on a bunch of different tests lately. These tips include: I'm seeing nmap scans get flagged a bit more from managed SOC services. Maybe a "quieter" nmap scan will help get enough ports to do a WitnessMe run, but still fly under the logging/alerting radar? Something like: nmap -p80,443,8000,8080 subnet.i.wanna.scan/24 -oA outputfile Using...

7MS #513: Interview with Christopher Fielder and Jon Crotty of Arctic Wolf

Today we're joined by our friends Christopher Fielder and Jon Crotty from Arctic Wolf to talk about their interesting report on The State of Cybersecurity: 2022 Trends (note: you can get some of the report's key points here without needing to provide an email address). The three of us dig in to talk about some of the report's specific highlights, including: Many orgs are running the bare minimum (or nothing!) for endpoint protection Cyber insurance costs are going up, and some customers a...

7MS #512: First Impressions of InsightIDR

Today I'm sharing some first impressions of the Rapid 7 InsightIDR as kind of a teaser for an eventual new chapter in our Desperately Seeking a Super SIEM for SMBs series. Disclaimer: remember these are first impressions. There may be some missed detections I talk about today that are a me problem and not the technology. I hope to get to the root of those unresolved issues by the time I talk more formally about InsightIDR in a future episode. Enjoy!

7MS #511: How to Succeed in Business Without Really Crying - Part 10

Today we're continuing our series focused on [owning a security consultancy], talking specifically about: How not to give up on warm sales leads, even if they haven't panned out for 5+ years!

7MS #509: Creating Kick-Butt Credential-Capturing Phishing Campaigns - Part 4

Today we revisit our phishing series with a few important updates that help us run our campaigns more smoothly, such as creating a simple but effective fake O365 portal, and being aware that some email systems may "pre-click" malicious links before users ever actually do.

7MS #508: Tales of Pentest Pwnage - Part 33

Hey friends! We have another fun test of pentest pwnage to share with you today, which is kind of tossed in a blender with some first impressions of ShellcodePack. We were on a bunch of pentests recently where we needed to dump credentials out of memory. We usually skim this article and other dumping techniques, but this time nothing seemed to work. After some discussion with colleagues, we were pointed to nanodump, which I believe is intended for use with Cobalt Strike, but you can comp...

7MS #507: Interview with Matthew Warner of Blumira

Today's featured interview is with Matthew Warner, CTO and co-founder of Blumira. We had a great chat about why out-of-the-box Windows logging isn't super awesome, "free" ways to get logging turned up to 11 (Microsoft's audit policy recommendations, sysmon, sysmon modular), as well as how to get better logging in hard-to-reach places like Kerberos. Be sure to also check out Blumira's resources on detecting Kerberoasting and simplifying Windows log collection and ongoing management with Poshim...

7MS #506: Tales of Pentest Pwnage - Part 32

Today's my favorite tale of pentest pwnage (again)! This time we're talking about sAMAccountName spoofing specifically. We also talk about my always-under-construction list of things I try early in a pentest for maximum pwnage: Run PingCastle Do the SharpHound/BloodHound dumps Run the DHCP poisoning module of Responder Check the ms-DS-MachineAccountQuota value in the domain - if its at the default (10), then any user can add machines to the domain. Why is the ability to add machin...

7MS #505: Pwning Wifi PSKs and PMKIDs with Bettercap

Hey friends, today I talk about the old school way I used to pwn wifi networks, then a more modern way, and then my new favorite way (spoiler alert: I use Bettercap).

7MS #503: First Impressions of Brute Ratel

Today's episode is all about Brute Ratel, a command and control center that is super cool, quick to setup, and much easier to use (IMHO) than Cobalt Strike. I also talk specifically about some of my favorite command line features, how slick and simple lateral movement is, and the "killer feature" that makes me giggle like the bad guy from Sonic the Hedgehog. In the tangent department, Mrs. 7MS makes an appearance via phone and I bore you to tears about my continued iFly addiction.

7MS #502: Building a Pentest Lab in Azure

Happy new year friends! Today I share the good, bad, ugly, and BROKEN things I've come across while migrating our Light Pentest LITE training lab from on-prem VMware ESXi to Azure. It has been a fun and frustrating process, but my hope is that some of the tips in today's episode will save you some time/headaches/money should you setup a pentesting training camp in the cloud. Things I like No longer relying on a single point of failure (Intel NUC, switch, ISP, etc.) You can schedule VMs t...

7MS #501: Tales of Pentest Pwnage - Part 31

Today we're closing down 2021 with a tale of pentest pwnage - this time with a path to DA I had never had a chance to abuse before: Active Directory Certificate Services! For the full gory details on this attack path, see the Certified Pre-Owned paper from the SpecterOps crew. The TLDR/TLDL version of how I abused this path is as follows: Grab Certi Grab Certify Run Certify.exe find /vulnerable, and if you get some findings, review the Certified Pre-Owned paper and the Certify readme fil...

7MS #500: Interview with John Strand

HAPPY 500 EPISODES, FRIENDS!

Hi everybody, today we're continuing a series we started way back in June called Securing Your Mental Health. Today I talk about some easy and relatively cheap things I'm doing to try and shutdown negative thoughts, punch imposter syndrome in the face, and be an overall happier and more positive person.  

7MS #497: The Stress and Satisfaction of Offering Live Security Training

Hey friends, today I'm giving you a peek behind the curtain of our Light Pentest LITE training to talk about the software/hardware we use to make it sing, the growing pains - and OMG(!) moments - that forced us to build in more infrastructure redundancy, and the cool (and expensive!) cloud options we're considering to offer a self-paced version of the course.

7MS #492: Tales of Pentest Pwnage - Part 29

Hello friends! We're long overdue for a tale of pentest pwnage, and this one is a humdinger! It's actually kind of three tales in one, focusing on pentesting wins using: Manual "open heart surgery" on the root of the Active Directory domain The new totally rad DHCP poisoning module of Responder An opportunity to abuse GPOs with SharpGPOAbuse (P.S. we talked about this tool about a year ago in episode 441)

7MS #491: Interview with Louis Evans of Arctic Wolf

Today we're joined by Louis Evans of Arctic Wolf to talk about all things cyber insurance, including: History on cyber insurance - who's buying it, what it does and doesn't cover, and when it started to be something you didn't want to leave home without What are insurance companies asking/demanding of customers before writing a cyber insurance policy? What basic things organizations can do to reduce malware/ransomware incidents (whether they are considering a cyber insurance policy or not...
