The ZIP of Death

This is a exploit of the compression algorithms to make a small zip that will extract into extreme amounts of data. There are more and better ways ones than this one, but i will only show how to make a simple 1k = 1m ratio.

1) Make a.txt file.

2) Open and type the null character (alt + 255).

3) Press ctrl + a then ctrl + v a couple times to make some null bytes.

4) If u have a hexeditor make the hex 00 for about 50 kilobytes.

5) Now make several copies of a.txt and name accordingly.

6) Open cmd.exe.

7) Type copy /b *.txt b.txt

8) Now every copy is made into a super copy and repeat.

9) Once you have a nice empty big text file like 1gb. Put it in a zip archive.
Because of the simple construction of the file, 1gb of null bytes.....!

The zip is only 1 mb in size and can really annoy friends.
For added fun hex edit the zip and you will see a bunch of hex 5555.

Just add some more and the file will expand amazingly.

Make sure to not open the zip this after.

You can always create your zip of death from the command line in linux
dd if=/dev/zero bs=1000 count=1000000 | gzip > test.gz

I'm amazed, I have to admit. Rarely do I encounter a blog that's both
equally educative and engaging, and let me tell
you, you've hit the nail on the head. The issue is something not enough people are speaking intelligently about. Now i'm very happy that I came across this
in my search for something relating to this.
