How To Make A Dangerous ZIP Bomb Which Expands To TBs


Zip bombs are very small files, that when unzipped, can expand from some few kilo bytes to thousands of terabytes, they are  usually used to take out antivirus software.
Zip bombs of course has a single base, a text file containing only 0s Usually that text file is 4GB, written in either notepad or wordpad, how you make a Zip File is explained below

1⃣ Open notepad or word pad and write in 1000 zeros and then you should have a text file of about 1Kb
2⃣ Now use the CTR+A, CTR+C, CTR+A buttons on your keyboard to select all, copy the selected and then paste it(respectively)
3⃣ Repeat step 2 until your text file becomes 4GB
4⃣ Now save the text file under any name with of course a .txt extension, so now you have a 4GB text file containing only of zeros
5⃣ Now Compress this text file into a zip file(This will be our base) let's call it zip1
6⃣ Now copy this zip file(zip1) 17 times and now you will have 17 copies of the original  zip1 file, and now zip all these zip1 files into 1 zip file let's call it zip2, now zip2 contains 17 zip1s
Now make 17 copies of zip2 and zip it into zip3
7⃣ Now continue step 6 until you have gone to zip5 or 5 layers, each containing 17 zip files
Now you know how to make a zip bomb, here is how it's used, hackers place zip bombs near their malware, so the zip bomb acts as a bait and the anti virus tries to open this zip file but then gets 17 smaller zip files and opens them, and the size increases unexpectedly fast and  the antivirus will either crash or stop opening these zip files and temporarly shut down, now the Malware will do its magic.
