7MS #334: IT Security Horrors That Keep You Up at Night

This week I got to celebrate Halloween with my friends at Netwrix by co-hosting a Webinar called IT Security Horrors That Keep You Up at Night. The content was a modified version of the Blue Team on a Budget talk I've been doing the past year or so, and essentially focuses on things organizations can do to better defend their networks without draining their budgets.

The presentation had a Child's Play theme and showed Chucky trying to hack Andy's company via:

  • Phishing
  • Abusing bad domain passwords
  • Abusing bad local admin passwords
  • Responder attack
  • Lack of SMB signing

Each attack was also followed up my some advice for how to stop it (or at least slow down its effectiveness).

The presentation itself was a blast and I learned some good public speaking lessons as a result:

  • Get your slides done early! - when co-presenting, it makes sense that they want to see your slides sooner than the day of! :-)

  • Don't freak out about an audience of "none" - I always think Webinars are weird because you can't see people's faces or interpret their body language to get a feel for whether they appreciate your humor or understand the points you're trying to make. I learned you just gotta keep pushing forward "blind" whether you like it or not.

  • Setup a redundant presentation system - ok so file this one with the irrational fears dept, but I actually had a second laptop ready with my presentation loaded, and the laptop was connected to a cell hotspot I setup on a tablet. That way if my machine BSOD'd or Internet went out in my house, I could quickly rejoin the presentation and pick up where I left off. Safe or psycho? You decide!

Happy belated Halloween!

7MS #593: Hacking Billy Madison - Part 3

7MS #593: Hacking Billy Madison - Part 3

Hey friends, today my Paul and I kept trying to hack the VulnHub machine based on the movie Billy Madison (see part 1 and 2). In our journey we learned some good stuff: Port knocking is awesome using utilities like knock: /opt/knock/knock 10.0.7.124 1466 67 1469 1514 1981 1986 Sending emails via command line is made (fairly) easy with swaks: swaks --to eric@madisonhotels.com --from vvaughn@polyfector.edu --server 192.168.110.105:2525 --body "My kid will be a soccer player" --header "Subject: My kid will be a soccer player" You could also use telnet and do this command by command - see this article from Black Hills Information Security for more info. Hyda works good for spraying FTP creds: hydra -l user -P passlist.txt ftp://192.168.0.1 Check out my quick cheat sheet about bettercap (see episode #522) for some syntax on extracting WPA handshake data from cap files: # ...it looks like the new standard hash type might be m22000 per this article (https://hashcat.net/forum/thread-10253.html). In that case, here's what I did on the pcap itself to get it ready for hashcat: sudo /usr/bin/hcxpcapngtool -o readytocrack.hc22000 wifi-handshakes.pcap # Then crack with hashcat! sudo /path/to/hashcat -m22000 readytocrack.hc2000 wordlist.txt

7MS #592: 7 Steps to Recover Your Hacked Facebook Account

Today we're talking about 7 steps you can take to (hopefully) reclaim a hacked Facebook account. The key steps are: Ask Facebook for help (good luck with that) Put out an SOS on your socials Flag down the FBI Call the cops! Grumble to your attorney general Have patience Lock it down (once you get the account back)! Also, I have to say that this article was a fantastic resource in helping me create the outline above.

7MS #591: Tales of Pentest Pwnage - Part 52

Today we talk about an awesome path to internal network pentest pwnage using downgraded authentication from a domain controller, a tool called ntlmv1-multi, and a boatload of cloud-cracking power on the cheap from vast.ai. Here's my chicken scratch notes for how to take the downgraded authentication hash capture (using Responder.py -I eth0 --lm) and eventually tweeze out the NTLM hash of the domain controller (see https://7ms.us for full show notes).

7MS #590: Hacking Billy Madison - Part 2

Today my Paul and I continued hacking Billy Madison (see part one here) and learned some interesting things: You can fuzz a URL with a specific file type using a format like this: wfuzz -c -z file,/root/Desktop/wordlist.txt --hc 404 http://x.x.x.x/FUZZ.cap To rip .cap files apart and make them "pretty" you can use tpick: tcpick -C -yP -r tcp_dump.pcap Or tcpflow: apt install tcpflow tcpflow -r To do port knocking, you can use the knock utility: sudo git clone https://github.com/grongor/knock /opt/knock knock 1.2.3.4 21 23 25 69 444 7777777

7MS #589: Tales of Pentest Pwnage - Part 51

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))

7MS #588: Becoming a Sysmon Sensei with Amanda Berlin

7MS #588: Becoming a Sysmon Sensei with Amanda Berlin

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.
