ZIP is a widely used file compression method. However, there are very dangerous files in the world that use the ZIP mechanism in reverse, called "ZIP bombs." In this video, we will first explain how compression works and explain the factors that cause the capacity to increase explosively when expanded (decompressed). We will take up the distinctive "non-recursive ZIP bomb" and examine what happens when this file is actually expanded (decompressed). ■Contents0:00 Opening0:25 Introduction (About compression algorithms)4:09 How ZIP bombs work8:57 The dangers of ZIP bombs9:29 Practical version12:43 Results of executing a ZIP bomb15:06 Details of the mechanism (non-recursive and recursive ZIP bombs)19:40 Conclusion■Notes・The contents practiced in the video may not necessarily be exactly as they are.
