@PhilippeDelteil Fair call, our mistake. It came from someone early in the field, and we stand behind him. If you’ve been in cybersecurity long enough, you know human error happens. We’ve been training defenders globally for 10+ years, first time this happens, and it’s already fixed.

@hackdef you just spammed a group of hackers 😅😅😅😅

The hacker spirit showed up strong at BSidesBUD. 🔐 Congrats to our @CTF winners 🏆—and respect to everyone who jumped in and played. Prizes sponsored by @hackdef & BSidesBUD. Keep hacking. #BSidesBUD2026 #CTF

From CTF to real-world defense 🚀 Cherifi Houdaifa 🇩🇿 @BSidesAlgiers | @shellmates Now CCWD Certified. Proof that hands-on training + CTF mindset builds real defenders. This is how cyber talent is forged. #CyberSecurity #CTF #BlueTeam #MalwareAnalysis

#Shellcode isn’t a tool. It’s how execution really works. Most people never get to this level. #CyberSecurity #ReverseEngineering #Infosec

Understanding the stack is fundamental for reverse engineering and malware analysis. PUSH, POP, stack frames, and return addresses control how programs execute — and attackers often manipulate them to hijack execution flow. #CyberSecurity #ReverseEngineering #MalwareAnalysis

#Malware checks for local interception tools. If it detects them, it may stop communicating. #INetSim simulates real internet services at the network level — reducing red flags and improving visibility. We teach it hands-on in Module 2: Tools Arsenal. youtu.be/5biJ5HS0qJg?si…

#HackDef se viene el 10th aniversario del torneo #CTF pionero en México, y queremos dejarle saber al mundo donde estan laborando esas promesas q ahora defienden organizaciones Ayúdanos a ser una motivación nacional para los futuros talentos mexicanos hackdef@hack-defender.mx

Malware doesn’t bypass Windows. It uses the same Win32 APIs as legitimate software: CreateFile. VirtualAlloc. CreateProcess. There’s no malware-only interface. The difference is intent — and defenders detect it by analyzing API behavior. #WindowsAPI #MalwareAnalysis #BlueTeam

Ransomware doesn’t encrypt files by itself. It uses crypto APIs. In the final part of Module 9, we intercept encryption in memory with NeZa and restore encrypted files. youtu.be/ZXr4QnYjdJY?si… #CyberSecurity #RansomwareAttack #MalwareAnalysis #BlueTeam #Cyberdefense

Malicious browser extensions abuse trust to steal data from inside the browser. At 𝙃𝙖𝙘𝙠 𝘿𝙚𝙛𝙚𝙣𝙙𝙚𝙧 𝘼𝙘𝙖𝙙𝙚𝙢𝙮, we teach how to analyze manifests, inspect extension JS, deobfuscate code, and detect runtime abuse. Browser security needs real analysis.
