how to make your own Zip Bomb of Death
1: Create a new text file, name it a.txt
Open and type the null character (alt + 255) in it.
2: Now press Ctrl + A then Ctrl + V a couple times to make some null bytes.
3: Open Command prompt and navigate to the folder containing a.txt . Type the following command:
copy /b *.txt b.txt
4:This will write all the contents of a.text and its copies into a new text file called b.txt, hence making every copy is a super copy. Repeat the above steps from the beginning again and again to make a really big text file.
5:Once u have a nice empty big text file like 1gb or more,then compress it using Winrar or Winzip into a zipfile.You will find that it will be compressed to very small size (about 1mb) It is because of the simple construction of the file as the text file contains 1gb of null bytes.
Notes & warning:
* Make sure that YOU DONT OPEN THIS afterwards.
* You can make the same file in Linux by typing -
[dd if=/dev/zero bs=1000 count=1000000 | gzip > test.gz]
* Make sure that your antivirus is turned off, otherwise it will consider Zip bomb as a malicious program.
Also,you can check out the one of the most famous zipbomb alive today –42.zip (only 42 KB) which will uncompress to about 4 Petabytes(1 Peta byte = 1024 TB and 1 TB = 1024 GB ) of file size.
