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 2020, I successfully completed all of the challenges and submitted my write-up to the Counter Hack Team for the second year in a row. This entry was one of 47 entries to earn a Super Honorable Mention, which is defined as:

SUPER HONORABLE MENTIONS
A group of people who really went above and beyond with their entries. Their write-ups were SUPERB, demonstrating excellent technical skills along with impressive communication skills.
