Zip bombs like Georgy.zip work by layering identical files or using repetitive data patterns that compression algorithms (like DEFLATE) can represent with very little code [5, 6].
Many zip bombs contain a zip file, which contains another zip file, and so on.
Strictly speaking, Georgy.zip is not "malware" in the sense that it doesn't usually steal your passwords or install a virus [5]. It is a tool designed to make your computer temporarily unusable [3, 6]. However, the sudden system freeze can lead to data loss if you have unsaved work open [2].
It is intended to overwhelm the computer's memory (RAM), disk space, and CPU, typically causing the system or the file explorer to freeze or crash [2, 3].
