About Me

I am Daylam Tayari, a junior cybersecurity college student at Arizona State University and incoming penetration testing intern at Bishop Fox who is currently based in Phoenix, Arizona, United States.
In my free time, I love working on various open source projects, enriching my cybersecurity skills, maintaining and improving my homelab and diving deeper in the Linux ecosystem.

I am an avid supporter of open source software and a privacy advocate, helping introduce people to better ways of protecting their personal privacy.

Ever since joining local infosec and Linux communities and being welcomed with open arms, I have thrived in them, introducing numerous people to them and even getting elected to positions of leadership in some of them.

After being an active member of Devilsec, ASU's cybersecurity club which holds weekly presentations with workshops and competes in national collegiate cybersecurity competitions, for numerous years, I was recently elected to Vice-President and have since helped push the club forward encouraging more interactive workshops and building a CTF platform for the club.
I also compete with Devilsec in collegiate cybersecurity competitions such as in the National CCDC.

I also am an active member of ASU's Linux User's Group (ASULUG) where we hold weekly events from installfests to hosting presentations on a myriad of topics, on top of being a welcoming community to ASU students, helping them setting up and configuring their Linux installations.

Whenever I am able to, I also attend talks hosted by PHX2600, Phoenix's 2600 group which hosts a wide variety of interesting talks from demonstrations of some of the first digital computers to talks on cybersecurity and lock picking.

I also remain active in an advisory position for ASU Esports Counter-Strike team having previously played on the varsity team and ranked as one of the best North American players playing competitvely on numerous teams before I decided to fully dedicate all my focus to cybersecurity and my career.

Thanks to my past interest in gaming, I learned about the livestreaming platform Twitch and started building minor tools for the community. When a major copyright restriction crisis hit the platform, developed a tool which aided streamers in the handling of their content including allowing them to recover 'purged' content which has gained over 100,000+ downloads (More details). Building this tool introduced me to Twitch's' GraphQL API and due to them still having public introspection fully enabled, started tracking its changes which included the implementation of new features which were only publicly implemented month later. By monitoring the changes on a regular basis, I was able to discover and announce the introduction of a 'brand safety score' which proved highly controversial leading to the posts alone getting millions of impressions and numerous articles about it in various publications.

I am originally from the suburbs of Paris, France and moved around a lot growing up so am fully bilingual in French (natively) and English, having pursued the majority of my education in English academic systems.
