SPIDER1CODE

بداء البث المباشر 🧑🏻‍💻

اجهزووو

الحمدالله دائما و ابدا 🤍 بعد دخولي ctfs 0xFun و IT Gate Academy و #snky جبت توتال فلاجات ليا كانو 8 اربعه في 0xFun و اربعه في IT Gate Academy و 95% من فلاجات كانت كريبتو 🧠🤍 و 5% كانو فرونزيكس 🧑🏻‍💻🤍 Alhamdulillah, always and forever 🤍 After joining CTFs like 0xFun, IT Gate Academy, and #snky I got a total of 8 flags. Four in 0xFun and four in IT Gate Academy. About 95% of my flags were in Cryptography 🧠🤍 And 5% were in Forensics 🧑🏻‍💻🤍 #CyberSecurity #CTF #CaptureTheFlag #Cryptography #CryptoChallenges #Forensics #EthicalHacking #InfoSec #BugBounty #SecurityResearch #CTFPlayer #OffensiveSecurity #CyberLearning #InfosecCommunity #BlueTeam

حد لاحظ اني نسيت اعمل بث ؟

سعيد جدا و فخور اني بشارك رايتب من اصعب رايتب الي موجودين علي منصه #flagyard الرايتب عباره عن تحدي كريبتو و حاليا مفيش غير 40 انسان حول العالم بس الي قدرو علي حل تحدي I’m happy to share a new CTF write-up I’ve published on Medium : “Reduced Collisions” 🧠🔐 In this challenge (Cryptography – FlagYard), I analyzed a custom hash function built on linear algebra and modular arithmetic, then exploited its structure to generate hash collisions. 🔍 What this write-up covers : Reverse engineering the provided server-side cryptographic logic Modeling the hash function as a linear system Applying lattice reduction (LLL algorithm) to recover valid collision vectors Crafting a working solution to obtain the flag This challenge was a great exercise in combining theory (linear algebra & lattices) with practical exploitation, which is something I really enjoy about cryptography-focused CTFs. 📖 Full write-up : https://spider1sec.medium.com/ctf-write-up-reduced-collisions-9373e48adc75

طبعا هيكون الجمعه الساعه 6 بتوقيت مصر 🤍 Of course, it will be on Friday at 6 PM Egypt time 🤍

البث هيبداء الساعه 6 و عشر دقائق عبال ما ناس تصلي

لاسبوع الجاي هنفتح بث نحل في ctfs من pico 🤍
