Capture the Flag: Final Scores – Ring 0 Wins!
Ring 0 pulled it off in the end, with VM to VM flag submission to prevent their own flags from going out on the wire, thwarting the McGrewchebag’s attempts at automated sniffing/resubmission. They were here all night hacking away and their devotion paid off. I expected to find them face-down on the keyboard when I [...]
CTF Weekend Update: Sunday 2:30 PM
The lab has been very busy this weekend. Yesterday at 3PM I received an email asking me to drop by and reboot the VMs due to sluggish performance, and I expected a handful of people in here when I arrived. When I got to the lab, I was very surprised to see a little over [...]
CTF Update: Friday 5:00 PM
After a very busy morning, the number of students in the lab hacking away at CTF went down in number, but up in rowdiness. There are three close “top” teams now, with “Where’s Jerry?” (formerly known as Team 4, name in reference to a missing member) joining McGrewchebags and Ring 0 in being very active. [...]
CTF Update: Friday Morning
Activity has seriously picked up after this morning’s brief class meeting. I discussed the events of my previous updates with them, clarified some rules, talked about useful tools, and gave a brief ramble on ways to effectively keep Wireshark from overwhelming them with data (or from crashing). Members of the previously less active teams are [...]
CTF Update: Thursday 5:00 PM
Today has been a busy day, but with slight movement to the scores. The two busiest teams, McGrewchebags and Ring 0, have been at work re-evaluating and re-deploying their sniffing and counter-sniffing measures. Representatives of two other teams have been by to poke at the network and their own reserved computers, yet remain quiet on [...]
CTF Update: Thursday Morning
I arrived to an empty lab this morning, just before 8AM, and the target VMs were running very sluggish. Rather than spending a lot of time diagnosing the exact problem, I felt it would be quicker to just shut the VMs down, restart VMWare, and bring them back up to see if they would spring [...]
CTF Update: Wednesday 5:00 PM
It’s time for me to leave the lab for the evening, but Capture the Flag and the participating teams march on.
After a briefing on the rules of CTF to the students from 9:00 to 9:45 this morning, this semester’s marathon Capture the Flag began. The five teams have until 9:00 Monday morning to rack up [...]
