A zip bomb is also kown as Decompression Bomb or Zip of Death. It is a malicious archive file created for a crash useless program trying to access it. A zip bomb is a small file is easy to transport and avoid suspicion. Mostly zip bomb is measured in kilobytes.

When a zip bomb is activated it fills up the complete storage of by decompressing into a very large amount of data.

For instance, there is a file called 42.zip which is 42 kilobytes in size but when unzipped, it is 42 petabytes - twelve orders of magnitude larger.

Zip bomb is used to disable antivirus software so that virus sent afterward could get into system undetected. When zip bomb is unzipped its contents are more than what the system can handle. This file easily unpacks into hundreds of gigabytes of garbage data.

42.zip file contains 42 kilobytes of compressed data with five layers of nested zip files in sets of 16. Every bottom layer archive containing a 4.3-gigabyte file for a total of 4.5 petabytes of uncompressed data.

How To Create Zip Bomb

• First, open up a text editor like notepad.
• Now start typing lots of zeros (0).

• Now open compression software like WinRar and compress this text file.
