According to its website, "the challenges focus(ed) on IMINT, GEOINT and journalistic investigative techniques surrounding a threat intelligence specialist, self-aware Roombas and containing the Coronavirus pandemic".
This would be the first official public OSINT CTF I participated in and although IMINT and GEOINT is not my strongest skillset, I've demonstrated I was able to handle it after solving an unofficial challenge provided by an instructor during my OSINT SANs course back in 2018, and eventually won the in-class CTF at the end of the course.
So after my buddy shared me the link to join - I accepted and invited another buddy of mine to join. Made up of 3 individuals, the team was called "Apa2Lah" which basically is a Malay language slang for "whatever".
The CTF organized by CYBAR was straight-forward. Solve the challenges, gain as many points as possible and the top few win the cash prizes. Our intention was simply to experience the kind of questions in this CTF and I have to admit, once we scored a couple of points, we got hooked and zoned into the challenges. Something I just wanted to spend like maybe 2-3 hours became 15 hours (the 9 hours was for sleeping and family time).
To cut the story short, we were able to answer all the question within 7 hours except for two questions. Two bloody questions, with the two highest score points, that we spent the remaining hours trying to solve them.
