[@MushokuThing]

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.

unrelated, but the htmls here are *quite* troublesome

@@competetodefeat4610 I'm pretty sure dude was talking about windows and its way of managing the zip bomb. Besides, you have to understand not always will a person be warned when having a zip bomb in his computer.

[@competetodefeat4610]

@@pedrodesu Again it initially handled it by telling him the file wasn't safe and Windows resisted allowing him to even store it. It's right there... in the video... him bypassing the warning. Windows EXPLICITLY said it could be malware, if you choose to ignore that then sorry but it's mostly your fault. So you're wrong, windows DID manage it correctly and he chose to disregard it and force Windows to let the file be saved onto system. He literally had to force Windows into saving it to begin with.

The real question from me though is, has anyone been affected legitimately by a zip bomb? I've been using the internet for over a decade and a half now and literally just heard about these for the first time. I feel like Defender would need a pretty big rework to deal with zip bombs as it would have to change its way of dealing with removing and extracting threats. Perhaps it's sufficient for it to warn you instead of taking immediate action?

Why explorer starts to see ghost files? Where do they come from? What is it actually reading? Fascinating

[@deadair32101]

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

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: \ / : * ? " < > |

[@CaseyDplays]

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.

[@benwitherspoon1038]

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 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.

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.

There's a registry key regarding path name character limit, I think it may be referring to that when you're unable to copy the r folder to r due to it having to add to that path name past the set value limitation. I believe it's set to 255 by default

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.

[@runed0s86]

It absolutely is! You can also edit the registry to remove the limit.

The replicating zip seems a lot like a fork bomb, except with storage instead of memory.

[@keeperofthehammer6795]

How did you compress a zip file further? When I tried to recreate this my first nested zip ended up maintaining the collective storage of the 16 zips inside it.
