About me

Hi! I’m Tobias Gabriel F. (aka Yw4rf), a Cybersecurity and Networking student based in Buenos Aires. I'm passionate about Blue Team operations, focusing on threat detection and digital forensics. I spend my time building home labs, analyzing traffic with Wireshark, and automating security tasks with Python and Bash. Beyond the classroom, I actively participate in CTFs to stay sharp and bridge the gap between theory and real-world defense.

I enjoy documenting my learning journey through write-ups and technical notes. Here are some of my featured labs and CTF resolutions:

• 2025-03-23 Volatility3 Analysis of STRELASTEALER via Rundll32 Proxy Execution
• 2024-11-23 LFI/RFI Chain to NTLMv2 Hash Capture and WinRM Access
• 2025-01-26 LLMNR Poisoning and NTLMv2 Hash Cracking
• 2025-02-19 APK Decompilation, LFI via Swagger API, and Solar-PuTTY Backup Decryption
