7MS #595: Choosing the Right XDR Strategy with Matt Warner of Blumira
Today we're joined by Matt Warner of Blumira (remember him from episodes #551 and #529 and #507?) to talk about choosing the right XDR strategy! There's a lot to unpack here. Are EDR, MDR and XDR related? Can you get them all from one vendor - and should you? Do you run them on-prem, in the cloud, or both? Join us as Matt answers these questions and more!

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 #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
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.
