Huntress CTF 2023 #
In October 2023, Huntress ran a CTF to coincide with Cybersecurity awareness month. The competition ran from October 2, 12:00 PM ET - October 31, 11:59 PM ET, with new challenges released every day.
" For this specific Capture the Flag competition, we hope to offer hands-on and practical exercises based around malware analysis, digital forensics and incident response, threat hunting or cyber threat intelligence, and general security. We will be releasing new challenges for you to play every single day throughout the month of October. "
I was late to the party and joined on October 25th and did what I could in those few days and completed 15 of the challenges across Forensics, Malware, Miscellaneous and warmups categories.
Any write ups for challenges not on that list I did after the challenge had finished.
