Join us at UAT in room 128, as we discuss the wonderful world of buffer overflow exploits in Linux Security: Agenda: Noon until 12:30 Greet, boot and rummage for last minute items. 12:30 to 12:45 Download presentation materials, get machines going. 12:45 Start Presentation - Lisa Kachold OverView History of Buffer Overflows Simplified Stack Architecture Code disassembly and build tools Stack overflow demonstration Layer Up or Stack above TCP Layer Down or Stack through to Application Layer Proof of Exploit on Production Systems Layer 8 or Mitigating the Risks 2:00 Break 2:15 Hack to Learn Labs We have desktops limited by UAT for web proxy and DNS/DHCP [Microsoft/Cisco MAC Address hammered down] running Win XP; we can boot Live CD's - but complete Internal DNS is also limited by MSDNS (external DNS is filtered) - so if you can port forward to your own DNS cache server for external DNS you have a fully featured Linux. UAT Wireless works, so if you bring your own Notebooks and LiveCD's you can easily hack using both systems, referring to reference materials via your own equipment. Alternately during the lab portion, we can successfully work in teams (to obtain escalated privs via buffer overflow) from one UAT Desktop running LiveCD while researching lab materials and accessing online sources from the other XP. These are basic skills for everyone to grasp, so come on over. Everyone attending HackFests agree to interact as ethical professionals, target only the systems that are clearly designated, and announce all flags.
