Basic Knowledge On Zip Bomber !! 🎇🎇

What Is A Zip Bomber

So,Hello Guys.

Welcome back to the G_Valtryek .I Kripto Geek heartily welcome you in my blog.This is about zip bomb and it's working.You will also get a gist  of how petabytes of files are converted into smaller files of kilo or mega bytes .Now I will take you through some things that will really intrigue you Let's get started straight away.

WHAT'S ZIP BOMB?

A zip bomb also known as zip of death or decompression bomb,is a malicious archive file designed to crash or render useless the program or system reading it.It is open employed to disable antivirus software in order to crate opening for traditional type of viruses.

Rather than high jacking the normal operation of a program,the zip bomb allows a program to work as intended,the archive is carefully crafted so that unpacking it i.e if an antivirus scan the zip file of viruses,will require inordinate amount of time ,disk space or memory.But as everything it  has certain limitations ofcourse .This zip file is very tiny zip file most of them are measured in kilobytes.Now you may have a lots of questions like -

1. Why is it so tiny?
2. Why call it a zip BOMB when it's so tiny?
3. How does it work?

1st -Why is it so tiny?

Zip bomb is a tiny zip file .Now it is made so tiny to avoid suspicion.It's obvious aint it?You don't want call the police you are thief,you make it look different.it  is made tiny because of compression of huge amount of data and the reason it being tiny makes using it a "pure hacker like mentality"

2nd -Why call it a zip BOMB when it's so tiny?

Never judge a book by it's cover.never underestimate smaller one's. It is called zip bomb or zip of death because it contains upto terabytes,petabytes or even exabytes of data.That's the key to clear out malware and hence blocking every obstacle in it's path leaving a strait asphalt. Now you will certainly want to know, how is it possible to complete such  large a file into a zip file of such  small size. Don't worry you will get your answers further. A simple example of a zip bomb is the file 42.zip,which is a zip file consisting of 42 kilobytes of compressed data,containing five layers of nested zip files in sets  of 16, each bottom layer archive containing a 4.3-gigabyte {4294 967 295 bytes;~3.99 Gib} file for a total of 4.5 petabytes{4 503 599 626 321 920 bytes;~ 3.99 Pib} of uncompressed data. this file is still available for download on various websites across the internet.In many anti-virus scanners, only a few layers of recursion are performed on archives to help prevent attacks that would cause a buffer overflow ,an out-of-memory condition, or exceed an acceptable amount of program execution time.

Dynamic programming methods can be employed to limit traversal of such files 

So that only one file is followed recursively at each level, effectively converting their exponential growth to linear.

3rd -.How does it work?

Zip bomb contains about petabytes of data, this if an antivirus tries to scan it, it will start to decompress it first. But just imagine what will happen if a file of about a kilobyte is decompressed and we get a file of about a few or more penta byte. The answers simple, before the zip file is completely scanned the antivirus will crash, creating a loophole for attackers.
