Hack The Box had our very first Business CTF just recently, from July 23rd to July 25th. To say the event was a smash success would be an understatement. Frankly, our event was more successful than we ever could have possibly imagined! You know what that means? We’re going to have a Business CTF each and every year. And things can only go up from here. We first mentioned the CTF on our blog about a month ago if you’d like to check that out.

Capture The Flag games in the context of cybersecurity and hacking are competitions where multiple hackers or teams of hackers hunt for metaphorical flags in an application, virtual machine, or virtualized network. The flags could be a line of code or any sort of hidden entity in software. Our Business CTF brings multiple teams together to compete against each other to see which teams can find the most flags. The teams who compete in our Business CTF are from companies of many sizes and in many different industries around the world. Our Business CTF is a fun way to train your employees to hone their cyber offensive skills in order to make your corporate networks more secure.

“HTB Business CTF 2021 was great. We all had a ton of fun and learned a lot. I most definitely would recommend the event to fellow cyber teams. HTB has the best selection of machines out of any CTF, hands down. The staff and support team has been superb as well, answering any questions we had within a few minutes! HTB offers a premium CTF experience that you cannot find anywhere else. Getting the team together and working on the challenges together was without a doubt the highlight from my perspective. Will join again next year.”

Harald Andreasen, Founder @ Xormatic 
Xormatic CTF Team Captain

“I really liked the HTB Business CTF 2021. Overall the challenges were pretty realistic, which is a big plus for me. Would definitely recommend joining the CTF, as it lets you test your skills in realistic scenarios, and challenge yourself against the best specialists in the field. The best moment was solving the Ghost challenge which was quite challenging. We will join again next year.”

Lukasz Lamparski, Security Manager | Senior Incident Responder @ ING
INGBank CTF Team Captain

“This was a very well-organized CTF. Would definitely recommend it to peers and other companies, and we will be looking to join next year as well. The biggest highlight of our experience during the hacking competition was the ability to learn new tech by exploitation.”

Our winners were motivated to show off their hacking skills. But they probably also were motivated by our huge competition prizes. They won £20,000 worth of prizes in total. Here’s what our winners received:

  • For first place, Xormatic’s team won six months worth of HTB Academy for Business training, a huge HTB trophy for the whole team, and Super Hacker capes for each of the team members, each player received a $100 Synack Swag Box, a £100 HTB Swag Card, a $50 HackerOne Swag Box, and the team received a $150 Hak5 Gift Card.

  • For second place, Synacktiv’s team won six months worth of HTB Advanced Dedicated Labs for Business, a $100 Hak5 Gift Card for the team, and each player received a £50 HTB Swag Card.

  • For third place, StandardNerds won three months worth of HTB Academy for Business, the team won a $50 Hak5 Gift Card, and each player received a £25 HTB Swag Card.

  • For fourth and fifth place, INGBank’s team’s players and 0xCD00’s players each received an HTB Pro Lab of their choice for a month and a £25 HTB Swag Card.
