@hunters_flag @KrakenEU_ @l30nuz @NavajaNegra_AB @AsturCONtech @Hack_en_ @8dot8 En seis meses sobra tiempo para hacer retos originales, a los hechos me remito que desde @flaggermeister montamos un begginer track con mas de 15 retos , un expert track con mas de 10 retos y una final presencial en 3 meses para la UAD de 2021 , no vengáis a robar a la carcel.
Viendo esta respuesta, no puedo más que sentir bochorno y asco profundo ante semejante caradura. ¿Justificar plagiar retos? ¿6 retos en 6 meses?. No tenía muy claro si escribir algo, pero allá vamos.[1/x]

CrowdStrike effectively bricked windows, Mac and Linux today. Windows machines won’t boot, and Mac and Linux work is abandoned because all their users are on twitter making memes. Incredible work.

Se acabó la #ROOTEDValencia. Una edición más, el equipo @Sofistic al pie del cañón!! Enhorabuena a toda la organización @rootedcon!! A descansar y nos vemos en la siguiente!!!
I'm happy to announce the release of Chainsaw v2! 🥳 Chainsaw allows users to rapidly search through Windows event logs and hunt for threats using @sigma_hq detection rules, all without a SIEM! Version 2 includes some exciting new features, info in 🧵 github.com/WithSecureLabs…
Write-up for the hard Forensics challenge SquatBot from the @hackthebox_eu Business CTF where my team @Sofistic ended in 18th position, 1st Spanish. github.com/Zarkrosh/ctf-w…
Record inflation. Market crash. War in Ukraine. Growing tension with China. School shootings. Growing cyber risk. Climate crisis. Supply chain issues. By all means let’s focus our efforts on limiting women’s rights instead. Absolutely idiotic.
Finalmente acabó el ctf de la uad360, con los siguientes finalistas. 🥇 @Zarkrosh 🥈 @asterixco 🥉@CampilloPatrick Os recordamos que los retos van a seguir activos durante un tiempo y esperemos que os haya gustado!
