### Sebucsert: ASD's Unsolved CTF Challenge

For three years sebucsert sat live each year on Pecan+ and was only solved last year. An encrypted document, how the document was encrypted and nothing more, where no player or organiser could work out the solve and with no solution.md provided, it was dead in the water. Following the conclusion of the ctf 2025 and hearing about how the challenge would be shelved we decided that we were going to face the challenge and solve it.

#### Sam & Ben

Sam Leong does a variety of IT-related things, like sysadmin, shaders and informatics, with the primary philosophy of 'if it ain't done right, do it yourself'
Ben Pye has great interests in various things cybersecurity and sword fighting but is often found in ctfs, writing scripts to privately exploit games or listening to Master Boot Record.
General Info:
CSides Monthly Security Meetups provide an opportunity to listen to and share security research within the Canberra region. The meeting occurs normally on the 2nd Friday of every month. Each meetup consists of 1-2 talks of around 30 mins each. Talks start at 6pm and are followed by some socialising at a local pub. New attendees are welcome, just come along! (There are no entry fees, and no tickets to book) The talks at CSides are technical. CSides welcomes new and interesting speakers to present - the topic will be on a technical or security issue. As a speaker you can be an expert, a student, someone learning a new area or maybe a regular speaker on the conference circuit, but we also love to have new and occasional speakers. Please contact one of the organisers below if you are interested in speaking. You are very welcome to propose running activites other than talks, such as hands-on workshops, an infosec quiz or something else relevant to our techie audience!
