Tresorit engineers conquer one of the world’s toughest hacker challenges

At Tresorit, security lies at the core of everything we do. To prove that we do what we say, we launched a hacker challenge back in 2013. We invited the best talents from organizations such as MIT, Stanford, Caltech, and Harvard to try to break into our servers offering a $50,000 bounty. No one succeeded – but we did not stop there.

We take immense pride in employing a team of world-class security engineers who are constantly motivated to uphold and improve their professional skills. They regularly attend the world’s toughest and most prestigious hacking competitions where they can learn from and compete with leading industry experts.

On that note, we are excited to announce that they recently won third place at Google “Capture The Flag” (CTF), one of the most recognized hacker competitions to date, competing as part of the !SpamAndHex hacker team. While Google CTF was running, other members of the !SpamAndHex team, including two Tresorit engineers, were competing in Japan where they secured 7th place in the finals of CODE BLUE CTF which took place a few days before. This is not the first time our experts have excelled in a competition; the team has a long history of making it to the top; earlier this year they came in fifth at Facebook’s CTF.

“As a security professional, it is important to always be on top of your game and at the forefront of industry trends. These trends often determine the type of challenges competitors must face – solving them helps keep us one step ahead of emerging attack techniques.” – explained JB, our top security engineer.

CTF competitions consist of a set of computer security puzzles involving reverse-engineering, memory corruption, cryptography, web technologies, and more. “Some of the challenges we have to solve at the CTFs require us to dig deep into commonly used frameworks and technologies many of which are used by Tresorit. Such analysis often sheds light on obscure, at times undocumented behavior, and helps us with our own in-house risk assessment and code review activities.” – he added.

At Tresorit, we feel incredibly lucky to work with a pool of top-notch security talents. Thanks to their motivation to continuously challenge themselves and upscale their skills, we have the best in house engineers keeping your data safe.
