If you're in cybersecurity, you've probably heard of CISSP All-in-One, The IDA Pro Book, or Gray Hat Hacking.

Now imagine learning directly from someone who co-authored the 4th and 5th edition of Gray Hat Hacking and has worked in global threat teams like Symantec, Mandiant, and Palo Alto Networks.

Hack Defender Academy (@hackdef) is built for defenders who want to go deep — reverse real malware, follow shellcode injected in another process, dissect infostealers, intercept ransomware encryption key in memory, analyze .NET threats with WinDBG SOS plug-in, automate the deobfuscation with our unique tool NeZa and sharpen your skills by solving live Capture the Flag challenges.

💻1200+ min streaming
🏁CTF-based labs
🛠️Your own IDA Classroom License

Led by DanuX (Dan Regalado), a veteran reverse engineer and speaker at REcon, DEFCON, and RSA.

This is not a passive course. This is real-world training — for real defenders.

Your hooligans burned the Palestinian flag and the Dutch flag ! They pulled Palestinian flags off houses . Then they started provoking , destroyed a taxi driver's car , and beat up the driver ! Some of them were seen with metal chains , ready to attack ! They refused to hold a minute of silence for the Valencia flood victims ! They even started illegal fireworks . They sang racist extermination songs against Arabs !

A Zionist plays the victim , just like a pig trying to claim purity and cleanliness ! 🤮
