About Me
> Security specialist focusing on defensive systems through offensive understanding.
$ whoami
I'm zer0x64, a cybersecurity specialist focused on finding and understanding vulnerabilities within modern applications. My work spans offensive operations, cryptographic audits, and memory corruption exploitation.
I approach systems with the belief that security is not a state, but a continuous process of analysis. Understanding how complex systems fail at a low level is essential to making them resilient.
# technical_expertise
0x01. Offensive Security
Penetration testing, network exploits, and red teaming. Specializing in demonstrating realistic threat vectors and bypassing complex defense systems.
0x02. Cryptography
Analyzing protocols, implementing cryptographic algorithms, and finding side-channel or logical flaws in custom crypto configurations.
0x03. Memory Corruption Exploitation
Decompiling binaries, analyzing malware, heap/stack exploitation, and writing custom tooling to inspect running process architectures.
! NorthSec CTF
I serve as a challenge designer for NorthSec CTF, one of the premier live-hacking events globally. My role is to design engaging, creative challenges that prioritize the fun factor and clever logic.
By building fun and innovative challenge environments, I help participants explore obscure exploitation mechanisms, from custom memory corruption bugs to complex cryptographic side-channels.
~ Philosophy
Security through obscurity is not security. I advocate for open-source analysis, detailed disclosures, and active collaboration within the white-hat community. The only way to build secure platforms is to fully understand how they break.

We seek after knowledge... and you call us criminals.
We exist without skin color, without nationality, without religious bias... and you call us criminals."
