Why explorer starts to see ghost files? Where do they come from? What is it actually reading? Fascinating
in order of question 1. explorer crashed likely due to running well past the normal file path limit 2. the files were either files that explorer failed to delete correctly due to the pathing issue or the like 3. Most windows programs deal with extremely long paths extremely badly, usually either failing to path correctly if not just outright crashing. only recently in windows 10 was a option to extend the file path limit even offered so most programs are still not ready for extended paths

I think what a lot of people are failing to realize, is that Windows Defender saw the original 42.zip and nuked it before FlyTech could do anything with it. But the encrpyted version has a different file hash, and the contents (lib*.zip) didn't have the zip bomb hash either. When he created a new zip file via Explorer, the resulting filesize was 547KB. The original is 42KB... The hash, without even having to actually hash it to check, is different. So why does this mean Windows Defender did nothing wrong? Because when scanning the zip file, it needs to extract the contents of the zip file to hash them to see if they are a known threat. To really explain how AntiViruses work would be far too in-depth for a youtube comment, and I only have a very very high level understanding of them at that, but ultimately Windows Defender did it's job. The known 42.zip, which is named 42.zip because it's a zip file with the filesize of 42KB that explodes to a massively larger filesize, was detected and deleted immediately.

I have a question. I noticed while copying images en masse from the photos app on Windows 10 that if you get too many it hangs windows. The process 1 have a LOT of pictures. 2 open the photos app to see all the photos from locations (folders) you told it to show. 3 select a LOT of them like 400 to 500 images. 4 right click and choose copy (Here is were it starts getting interesting) 5 open an explorer folder that is not the one where the pictures are stored 6 right click inside the folders blank space and click paste. If it's only a few photos being copied this goes on without a hitch. But when there are lots of photos being copied many glitches seem to happen Some of them were explorer not responding when trying to open a folder. The Windows clipboard 'forgetting' it has copied photos and so wont let you paste them The photos app using lots of ram and CPU The photos app crashing without any error message ... It just disappears and can be reopened without issue but all your selections will be lost An already open folder when clicked on in the taskbar to bring to front will give the "you can't do that" ding tone appear in front of the photos app then instantly go behind it again. This effectively makes it useless You can stop this behavior by clickinh the X for the folder in the preview image over the task bar after hovering the mouse over the taskbar folder icon. The computer I did this on had 8 gigs of ram a 4tb external hdd (which is what I was moving the photos on [not on to as they photos were simply being moved from one folder to another on the same drive they were already on]) and a quad core processor. This pc also has a sepreate GPU though I'm unsure if it played a role in this or not. Anyone it was just some intresting windows 10 and photos app behavier I've noticed.
You're flooding the clipboard app with more than it's available memory and are essentially creating a stack overflow and using more RAM than the computer has.
To prevent explorer from freezing completely, make sure to check out the folder options, there is an option called something like "open a new window as a seperate process" Definitely easier to troubleshoot this way, and you don't lose all the other open folders.
The action that Windows Defender took was basically "Hey, there's a landmine there. Stay away from it, while I go there and step on it so it doesn't harm you."
The reason why you cannot extract encrypted ZIP files is because you have to extract the main ZIP file that is holding all those encrypted ZIP files and enter the password that links to the encrypted ZIP files.
8:17 you can get above compatibility limit in explorer easily by changing a registry key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem] "LongPathsEnabled"=dword:00000001 While Windows' standard file system (NTFS) supports paths up to 65,535 characters, Windows imposes a maximum path length of 255 characters (without drive letter), the value of the constant MAX_PATH. This limitation is a remnant of MS-DOS and has been kept for reasons of compatibility. There used to be even shorter names - 8.3 filenames (also called a short filename or SFN) is a filename convention used by old versions of DOS For performance reasons, it is better to avoid more than 4 levels of subdirectories and loading more than 5k items from a directory :) I had a problem once in a Linux distro where by default screenshots had 𝐡𝐡:𝐦𝐦 in the file name. Windows photo viewer refused to work with it since a filename in Windows cannot contain any of the following characters: \ / : * ? " < > |
“Are you Windows Defender?” “Yup.” “And this is a zip bomb?” “Yup.” “I found this zip bomb, so can you delete it?” “That makes sense to me.” “Then delete it.” “ *EXTRACTING* “
A zip bomb is a type of ZIP file that is way too compressed. Some applications like Windows Defender handle it incorrectly and when trying to remove, it tries to extract the bomb, causing SSD Utilization to peak 100% and stay on 100% and causing the CPU tons and tons of pain. Link to see more: en.wikipedia.org/wiki/Zip_bomb
I had a program that generated a super deep directory in Windows before. It wasn't a virus, but Windows started updating and locked some of my folders causing the program I was using to bug out. I ended up having to write a recursive directory walker program to fix it, because I couldn't delete a folder tree 3,000 levels deep... Windows did not appreciate that.
I first learned about zip bombs and the logic behind file compressions back when I was (I think) 12 or 13 years old (around 7 years ago). But Jesus Christ, I didn't know bottomless zips are a thing until now. That really piqued my curiosity about zips again.
So apparently there's a default file path limit in Windows of 260 characters (I learned this when dealing with massive file hierarchies at work). This could be part of the problem in your r.zip section.
It's fascinating that Defender recognises zip bombs as actual malware. I wonder what it's looking for... It can't be zipfiles inside other zipfiles. Is it the compressed size vs uncompressed being completely unusual?
I have seen that Avira always takes a bit of time and disk activity when scanning Java's rt.jar archive (which is really a zip file). It has many directories with a lot of files, including more archives inside.
Well, there's your first problem. Using an online adblocker other than windows defender will actually cause more lag! I'm sad that they didn't try the offline windows defender scan. It may or may not have deleted the file.

I think I tried to do this on a school computer where I would take a picture and put it into a zip and put that in a zip and so on and so forth, just to see if the system had some kind of hard limit to how many times you can nest a zip file. It was a 15kb jpg, so it never did anything significant 😂
I think the issue is that it only realizes its a zipbomb after like the 2nd or 3rd level, but thinks the rest of the file is good. So it attempts to remove the part of the zipbomb that it deems a virus, but the catch is that 1) the whole thing has to be read and rezipped to delete a part, and 2) the whole thing should really be deleted

Thanks for this video! I was trying to figure out if my Windows installation was bugged or if Defender was really that bad at handling threats in zip files
I enjoyed the music more than the content. That means that I absolutely loved the music and very much loved the content.
Windows: hey this is bad let me remove it

Nestless ZIP bombs, when you want to fill your host space using a VM with a self-expanding drive.
@c6amp exactly
wdym self expanding?? once it reaches 100% of the capacity you assigned it doesn't expand further
@stelios m never seen that before but I can believe it
@@midleno8364 basically it expands in size when you add more files to the VMs disk
3:50 This is where Windows defender tries to kill your main SSD by constantly writing data (known as SSD degradation)
Hopefully, this will urge Microsoft to fix it. If I remember correctly, you can submit bugs to Feedback hub. I've solved a bug with their thumbnail creator doing so

woah
Windows Defender: There's a zip bomb in this. Do not extract it! I'll get rid of it for you.
User: Okay, get rid of it.
Windows Defender: Alright. *extracts zip bomb*
*IN ANOTHER TIMELINE*
Windows Defender: Eh, this file isn't worth the effort unzipping. Just let it through. We'll be fine.
6:44 that's why you don't use a vm with a dynamic drive when playing with zip bombs
I always use static drives at 8-16GB
Even those should cap the size, right?

it's amazing to see that you can do damage via zip file.
I have a question. I noticed while copying images en masse from the photos app on Windows 10 that if you get too many it hangs windows.
The process
1 have a LOT of pictures.
2 open the photos app to see all the photos from locations (folders) you told it to show.
3 select a LOT of them like 400 to 500 images.
4 right click and choose copy
(Here is were it starts getting interesting)
5 open an explorer folder that is not the one where the pictures are stored
6 right click inside the folders blank space and click paste.
If it's only a few photos being copied this goes on without a hitch.
But when there are lots of photos being copied many glitches seem to happen
Some of them were explorer not responding when trying to open a folder.
The Windows clipboard 'forgetting' it has copied photos and so wont let you paste them
The photos app using lots of ram and CPU
The photos app crashing without any error message ... It just disappears and can be reopened without issue but all your selections will be lost
An already open folder when clicked on in the taskbar to bring to front will give the "you can't do that" ding tone appear in front of the photos app then instantly go behind it again. This effectively makes it useless
You can stop this behavior by clickinh the X for the folder in the preview image over the task bar after hovering the mouse over the taskbar folder icon.
The computer I did this on had 8 gigs of ram a 4tb external hdd (which is what I was moving the photos on [not on to as they photos were simply being moved from one folder to another on the same drive they were already on]) and a quad core processor. This pc also has a sepreate GPU though I'm unsure if it played a role in this or not.
Anyone it was just some intresting windows 10 and photos app behavier I've noticed.
You're flooding the clipboard app with more than it's available memory and are essentially creating a stack overflow and using more RAM than the computer has.
Windows photo app has always been borderline non-functional
To prevent explorer from freezing completely, make sure to check out the folder options, there is an option called something like "open a new window as a seperate process"
Definitely easier to troubleshoot this way, and you don't lose all the other open folders.
Defender: hey this file is dangerous lemme remove it

I'm still learning bash, can someone explain to me what does the "do" command do and what is the ":;" after "while" in 7:37?
`do` is syntax for a loop.
while ; do cmd1; cmd2; ..., cmdN; done
Setting : as condition is equivalent to `while true`, i.e. an infinite loop

The reason why you cannot extract encrypted ZIP files is because you have to extract the main ZIP file that is holding all those encrypted ZIP files and enter the password that links to the encrypted ZIP files.
8:17 you can get above compatibility limit in explorer easily by changing a registry key:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem]
"LongPathsEnabled"=dword:00000001
While Windows' standard file system (NTFS) supports paths up to 65,535 characters, Windows imposes a maximum path length of 255 characters (without drive letter), the value of the constant MAX_PATH. This limitation is a remnant of MS-DOS and has been kept for reasons of compatibility.
There used to be even shorter names - 8.3 filenames (also called a short filename or SFN) is a filename convention used by old versions of DOS
For performance reasons, it is better to avoid more than 4 levels of subdirectories and loading more than 5k items from a directory :)
I had a problem once in a Linux distro where by default screenshots had 𝐡𝐡:𝐦𝐦 in the file name. Windows photo viewer refused to work with it since a filename in Windows cannot contain any of the following characters: \ / : * ? " < > |

“Are you Windows Defender?”
“Yup.”

“Yup.”

A zip bomb is a type of ZIP file that is way too compressed. Some applications like Windows Defender handle it incorrectly and when trying to remove, it tries to extract the bomb, causing SSD Utilization to peak 100% and stay on 100% and causing the CPU tons and tons of pain.

I had a program that generated a super deep directory in Windows before.
It wasn't a virus, but Windows started updating and locked some of my folders causing the program I was using to bug out.
I ended up having to write a recursive directory walker program to fix it,
because I couldn't delete a folder tree 3,000 levels deep... Windows did not appreciate that.
godness..
its like Minecraft where you put a chest of chest of chest of chest... (using nbt) to a chest
I first learned about zip bombs and the logic behind file compressions back when I was (I think) 12 or 13 years old (around 7 years ago). But Jesus Christ, I didn't know bottomless zips are a thing until now. That really piqued my curiosity about zips again.
Flytech: I don't know how to stop it.
Also Flytech: *Forgot to delete the zipped folder
Windows: how am i supposed to throw away the garbage without opening the garbage bag?
So apparently there's a default file path limit in Windows of 260 characters (I learned this when dealing with massive file hierarchies at work). This could be part of the problem in your r.zip section.
It absolutely is! You can also edit the registry to remove the limit.

It's fascinating that Defender recognises zip bombs as actual malware. I wonder what it's looking for... It can't be zipfiles inside other zipfiles. Is it the compressed size vs uncompressed being completely unusual?
I suppose it's the compression factor, yes

I have seen that Avira always takes a bit of time and disk activity when scanning Java's rt.jar archive (which is really a zip file). It has many directories with a lot of files, including more archives inside.
Well, there's your first problem. Using an online adblocker other than windows defender will actually cause more lag!
I'm sad that they didn't try the offline windows defender scan. It may or may not have deleted the file.

I think the issue is that it only realizes its a zipbomb after like the 2nd or 3rd level, but thinks the rest of the file is good. So it attempts to remove the part of the zipbomb that it deems a virus, but the catch is that 1) the whole thing has to be read and rezipped to delete a part, and 2) the whole thing should really be deleted
of course it'll crash, you're going over the path limit
The one with the unlimited Folders is exactly the shit that happens with some Users on Network Drives when they are giving Files and Folders complete sentences as Names and crash whole Network drives without noticing.
going down far enough gives explorer PTSD and it starts hallucinating r.zip.
