On my way to #H121 in Lisbon 🌞
Super cool to see the first LHE from @Hacker0x01 in Portugal.
Back in the day, @Regala_, @JLLiS, and I pitched this idea. Happy to see it finally happening!

Back in 2015, the @xstf_team team was founded at @uporto. I got invited to the first CTF and embraced the captain role shortly after.
In the first months, there were just 3 active players: @JLLiS , Joana Barão, and me. Almost no one wanted to join us. But we still pushed through sleepless nights, sometimes ending up with 0 points in multiple CTFs as we worked to grow the team.
Then, @cirne12, and now @goncalomelo_sw, stepped up as captains and took the team to a new level.
Let's go!

Hey everyone! It’s that time of the year again to vote for the top web hacking techniques of 2019.
Personally, i’m rooting for nullboi and exploring CI as a bb hunter (as im named in both) but desync http and google search xss are cool as hell portswigger.net/polls/top-10…

Last Sunday I had the pleasure to interview @0xacb: another @Hacker0x01 MVH, @0xDISTURBANCE member, and also known as the "the Shopify RCE guy". We talked about winning a CTF to go to live hacking events, reverse engineering, and getting an RCE on Steam. youtu.be/qq-JEV4ptTw?t=7574
