13 Jeff Crocker - Responsibilities Email Server

14 Jeff Crocker - Preparation Email Server Online Tutorials Veteran Knowledge Presentations Passwords

15 Jeff Crocker - Mistakes Open Relay Fix Sitting by the phone User Accounts Excessive Passwords

16 Jeff Crocker – Lessons Learned Check Assumptions Gear Switching Googling Skills Availability vs. Integrity

17 Ben Cumber - Responsibilities Windows File Server Windows 2008 R2 server Running freeFTPd Windows XP workstations 7 and 8

18 Ben Cumber - Preparation Windows hardening guide on personal machine. Read through team binder. Reviewed PRCCDC rules.

19 Ben Cumber - Mistakes Couldn’t RDP to Windows server. Could not connect to file service. Reinstalled file service (wasn’t necessary)

20 Ben Cumber – Lessons Learned RDP Filezilla and WinSCP Gained a much better understanding of what exactly a file server is.

21 Keith Drew - Responsibilities Maintain Logs of System Changes Maintain Telephone Logs Windows Workstation Hardening

22 Keith Drew - Preparation Documentation Mini Lab on Personal Computer Developed Hardening Guides

23 Keith Drew - Mistakes Not killing malicious process Not utilizing all tools available to me (Vsphere Client)

24 Keith Drew – Lessons Learned How attacks are performed

25 Heather Haphey - Responsibilities Smoothwall Virtual Router Handle injects Policy writing Report generation Briefing Binder creation

26 Heather Haphey - Preparation Researched Smoothwall and Virtual Routing Reviewed and rewrote real policies Practiced briefing Collected and created binder materials Read offensive and defensive tactics

27 Heather Haphey - Mistakes Learned wrong Virtual Router Vyatta instead of Smoothwall Didn’t back up editable sample documents Realized the router GUI too late Not prepared to detect and prevent attacks

28 Heather Haphey – Lessons Learned More research about red team tools Back up anything useful Snapshot -> Harden-> Snapshot Get injects done ASAP, use full time Review requirements part-way through Stay focused on AOR, remain calm ASK ASK ASK and trust intuition Get into the scenario, seek real answers

31 Nate Krussel - Mistakes Firewall Rules Need to only allow certain IP’s to be allowed to access domain, and domain resources Should slow down the red team To much time as Domain Admin account Much easier for red team to steal credentials if they break into the box Not checking schedules tasks Allowed red team to manipulate our firewalls across domain Didn’t lock out all additional user accounts that weren’t required for score bot or us Not how a normal business runs, but works well for the competition

32 Nate Krussel – Lessons Learned Always scan inside and outside your network and speak up if a new box appears If given vsphere client, turn off servers RDP and ssh abilities (if possible) and use the client Check firewall rules regularly Use virtual router to try and limit access by port level if possible, reduces attack surface greatly Always communicate and make sure to get conformation of a task that needs to be done to make sure the message got across Easier to have the DC auto update the group policy instead of having everybody update it themselves

33 Chris Waltrip – Responsibilities Kali Linux VM Outside of Corporate Network Used to see what is visible from the outside Port Scanning Network Sniffing Vulnerability Analysis Windows Server 2008 R2 (HMI Server) Not initially planned

34 Chris Waltrip - Preparation Learned the basics of Nmap and Wireshark Researched Web Application Firewall Specifically ModSecurity Never actually used Created Cheat Sheets Useful Tools Common & Useful Commands

35 Chris Waltrip - Mistakes Didn’t see VPN on Second Day Nmap Port Scans Wireshark DNS Traffic HMI Server Saw server, but thought was Vyatta Firewall Didn’t know Default Credentials Attached to Domain Cobalt Strike Beacons
