A hooded hacker occupies the foreground, their figure illuminated by a glowing digital visor cutting through the dark. They sit at a futuristic desk, fingers racing across a dazzling neon keyboard. Surrounding the hacker are floating holographic screens, displaying streams of glowing code, fiery digital firewalls, and fragmented glitch effects. Behind them, a slick neon-lit city skyline stretches upward, drenched in cyberpunk style with digital billboards casting eerie glows. Towering among the cityscape, a futuristic university building crackles with subtle glitch effects. Rain falls diagonally across the cover, reflecting vibrant neon blue and electric purple against deep black streets tangled with cables and wires. Glowing binary code scrolls faintly through the foreground like an overlaid texture, adding depth to the scene.

The title, “GDGC Cyber Siege,” is bold and glitchy, rendered in fragmented neon hues of cyber red and vibrant pink, with subtle flickers mimicking screen errors. The author’s name, “GDGC Team,” is displayed in sleek, modern sans-serif font at the bottom, glowing faintly in neon blue to complement the overall tone.

The hacker dominates the lower third of the composition, creating an anchor for the viewer's eye. The book’s title is at the top center in large, glitchy font, stretching across the skyline yet leaving the background visible. The author’s name sits unobtrusively at the bottom, blending seamlessly into the rain-soaked street. The floating holographic screens are arranged organically around the hacker, leading the eye into the background where the futuristic city skyline and university building complete the scene.
