Write-up

For those looking to learn or expand on their technical abilities these types of challenges can often be a good starting point with many participants choosing to document and publish their write-ups for every challenge completed.

Included as part of the SANS HHC is the option to submit your write-up for each challenge (prior to the deadline) to enter into the SANS Contest.

In January 2021, I successfully completed all of the challenges and submitted my write-up to the Counter Hack Team for the third year in a row. This entry was one of 77 entries to earn a Honorable Mention, which is defined as:
