Hack Sim Unity · Hacking Simulator
In Development

A hacking-simulator sandbox built solo in Unity โ€” terminal-flavored gameplay wrapped around systems built from scratch, from the ground up. Same obsession that drives the CTF write-ups on strikesec.tech, pointed at making something playable instead of something exploitable.

๐Ÿ“Œ More Projects

๐Ÿช™ CoinGrade AI Live

AI-powered coin grader โ€” upload obverse & reverse photos and it analyzes wear, luster, strike quality, and eye appeal to assign a grade on the Sheldon 1โ€“70 scale used by NGC and PCGS.

๐ŸงŠ DropToFloor_Blender Public

A Blender add-on that snaps any selected object straight down to the nearest floor or plane with a single right-click in object mode โ€” no more nudging things into place by hand.

๐Ÿ“ก JoystickChannelIDgrab Public

A small Python utility that grabs a channel's ID straight from Joystick.tv โ€” built for quick lookups instead of digging through page source by hand.

๐Ÿšฉ CTF-Writeups Public

Walkthroughs and exploitation notes from HackTheBox and PicoCTF boxes โ€” recon, privilege escalation, and everything in between, documented as I go. More on strikesec.tech.
