&YBNQMF$5'

&YBNQMF$5' - The flag is displayed after successful login -
In CTF events that contain multiple challenges, there is often a common prefix for flags, in this case "techverse_", and this prefix can serve as a hint to participants

&YBNQMF$5' - The flag value is confirmed by the facilitator,
or by a judge server - In the case of a judge server and multiple teams participating in the event, you can make a scoreboard etc. - If there is a scoreboard, it's common to reward more points for more difficult challenges Facilitator Judge Server

CTF as an equalizer • No matter how much experience
you have, there's always something you haven't learned or tried before • Experienced team members don't have all the answers • CTF can demonstrate this • Experienced team members can guide about how to learn and investigate Preparation •CTF can help us be prepared for real work scenarios Creativity •Not only solving, but also making interesting CTF challenges requires creativity $POOFDUJPOUP&OHJOFFSJOH$VMUVSF

• Capture the Flag events are active and represent "do"
as compared to "tell" • The facilitator learns how to give hints and guidance without giving the answer • Effective hints are often given as questions that need to be answered, rather than as statements about the challenge • Participants learn the engineering and security concepts needed to solve the challenge, and also learn "what questions to ask" when doing an investigation $POOFDUJPOUP&OHJOFFSJOH$VMUVSF
