We are The Shades — a competitive Capture The Flag team operating from the intersection of deep technical skill and creative problem-solving. We don't just play CTFs; we study the craft.

Our team specializes in Binary Exploitation, Reverse Engineering, Cryptography, and Web Security. From heap grooming to obscure WASM vulnerabilities, we go where the shadows are deepest.
