3:52 This wasn't Windows trying to prevent repeated misuse, what happened was that when you saved the file, it wasn't written to the disk, it was in a disk-cache, and you crashed the system before the buffer was flushed to disk, but the MFT contains the expected size of the file, so when you open it, it just shows the correct number of bytes, but all null. This is an insidious problem that most people aren't aware can happen. I learned it the hard way one day when I had a BSOD and upon reboot, noticed that some files that had been created just before the crash were now blank. If I hadn't noticed, they would have remained blank but still set to the expected size and no indication of corruption. The reason I noticed was because the files were image files and when I rebooted, I noticed they weren't showing thumbnails. If not for that, I could have continued on, blissfully ignorant of corrupted files forever. Now, whenever Windows crashes, I boot into safe-mode to prevent files from being written to the disk, then do a search for files created or modified in the past day, and check the last few that were touched before the crash to see if they were corrupt. If you want to avoid losing data of an important file, you can get Uwe Sieber's drive-tool FFB to manually tell Windows to Flush File Buffers to ensure the file is written out to disk. It's one of the most important tools. This happens on internal drives that have their policies set to optimize speed since they're not removable; removable drives like flash-drives and memory-cards default to quick-removal and should write data directly to the drive, not to a buffer (at the expense of speed). You can usually change the policy of drives in the Device Manager. 5:44 Or you can hold down the Shift key to prevent startup items from running. Also, you put it in "shell:startup" which puts it in the current-user's auto-run. Holding Shift during boot will prevent the system from automatically logging into the user's account, so you can log into a different user and delete it from there. If you put it in "shell:common startup", then it would run on boot, so you'd have to hold Shift to prevent auto-run from running. 7:53 This is probably a race-condition, the shell is trying to run the random file before it's finished being written. Try changing the command to put the run command on the same line as the copy command with with double-ampersands (&& instead of &) to require to only run if the copy command has returned success. 8:11 It's heuristics.

No doubt the reason the file is being replaced with zeros is that it crashed before the disk cache was flushed, so the file content hadn't actually been written to disk yet. If you create the file and then reboot normally, it should stay. That also explains why some other methods didn't have that problem, because they took longer and did more file I/O, so the cache had time to be flushed. This is also why it's important to shut down properly.

Wow that’s really interesting. Is there any documentation on the thing where Windows replaces the characters with null bytes in the batch file? I’ve actually been seeing that exact thing happen on some Windows machines at my job and couldn’t figure out why an XML file had a bunch of null bytes in it instead of the data I expected.
I suppose it could be, but there’s over two dozen involved servers virtualized in a enterprise data center. The number of null bytes matches the amount of characters I would expect to be in the file and it happened right as the operating system crashed. We think it’s related to antivirus software scanning it at the time.
I suspect defender notices the self-copying file and when it tries to kill/inspect it, it runs into the path, makes a request to see what the file contains (to find out if the file is part of the malware) , and then confuses the computer into BSOD'ing

When I was in university, there was Windows 98 or 95 on computers, Norton Commander, Turbo Pascal etc. So, once I was looking onside different files and inside IO.SYS I found all those device names - CON, PRN, LPT1, COM1 etc, including CLOCK$. So I edited this file and changed "CLOCK$" to "SYSTEM". As a result, when Windows tries to boot, it just hangs before switching to graphics mode, with error message something like "Cannot find blabla.vxd". I don't remember exact text, nor name of that file, probably vmm32.vxd. You can boot to dos using F8, and use dos programs, but you cannot cd into any folder named SYSTEM.

Something interesting happens when doing this in VBox with EFI enabled: I have a windows 10 host, testing this bug with a Windows 10 VM running off Vbox EFI (experimental I think). The path crashed the VM as expected. Then the machine rebooted... And a few seconds later my *HOST* BSODed from a VirtualBox driver exception... DRIVER_IRQL_NOT_LESS_OR_EQUAL....
I wanna know when the user is bsod but the file is still there, but the inside of it's just NUL. So the question is why my watch in some app it said NUL? Is may watch can BSOD to? (4:17)
@Executed you can legit just flash a new windows install, or you can boot off a usb, mount the old hard drive and recover files. Or literally just remove it from startup in 15 seconds.
Hey Fly, I'm really curious about the crash that keep on occurring on loop which was not intended to when defender detected a threat or so.... Did you find the reason ?
When Defender finds the threat, it tries to access the directory the threat is detected from, since the directory is the crash dir, it will crash the system, my theory anyway.
I would be interested in a video that explores the consequences of changing the function to not require parameters, if that isn't how windows dealt with it.
You can't jeally just "make" a function not require parameters. You can try to catch the exception, but that also would literally just get rid of this one BSOD and nothing else

@@spammymcspambox4603 obviously, cause linux’s whole entire filesystem is different, heck, the two kernels are completely different
Yet another win for 🥇superior Linux🥇 😎

6:25 no cmd /c

i said it then and i will say it now: windows is seriously a broken mess
Yet it's used by mostly everyone.
Use Linux. It’s basically perfect.

I experienced a bsod on my windows 10 laptop on the first day of arrival, i was actually crying for hours and luckily i somehow fixed it
i got trolled by my friend he sent me that link then my laptop crashed and my monitor just starts to say no signal
SO I SEE THIS IS USEFULL FOR TROLLING
Lol, i was about to do this to my firends as well
Same
Lol just sent this to my friends
Dont do it! Sometimes it causes permanent damage
\\.\GLOBALROOT\Device\ConDrv\KernelConnect
Here ya go
Thank you!
I Dont Have PC
I Have One
what if you do it on chrome book will it work im on a school chrome book-
in like late 90s AOL they let you play sounds in the chat if you typed in a short command and the filename and if you tried playing con/con it would bsod anyone who hadn't disabled their sound
if i do this, will it restart the script on every reboot?
@echo off
copy /y %~f0 "%appdata%\Microsoft\Windows\Start Menu\Programs\Startup\mssec.bat"

This _does_ work in a local HTML file for me. I tested it in Brave Browser, which is a Chromium spinoff. It was reproducible as an img src.
eyy i use brave too
I don't get how Brave is 6x faster than Edge, Chrome, Firefox and Opera
@@zank8470 maybe cutting out the time spend loading code that tracks you. 6x is still a lot though...
@@lucrativelepton for me, brave is slower than edge and chrome is slower than edge

I tried this on my win10 VM and it did not work, maybe the bug was in earlier versions of Windows 10
I had a BSOD yesterday, just let it restart. It doesn't harm anything for me.
If anyones curious how he recorded the blue screen, he used a VM
i know that's what he did, but you can also do hdmi capture
@team lolpippiou there are hdmi capture boxes as well, for recording console gameplay
Duh
I'm on my phone so I can't check but can webpages redirect in any way to a local resource? I'm pretty sure the open() function won't work but what about editing the url directly?
i tried anything i could think of (window.location.href, window.location.replace, window.open etc) and every time i got the error. i even tried generating an a-element into the dom and setting the url to the bad path, but still got stopped by the local-protection. the protection really applies to everything.
@@FlyTechVideos Yeah I tried too, well better for security I guess
@@FlyTechVideos Maybe a gigabyte of RAM would do the trick?
if you go on a virtual machine thats on windows 95 or 98 or 2000 or ME, type in the run command "con/con/con" that will bluescreen the virtual machine
me: * attempts to bluescreen my entire computer by accessing a weird file *
google: -ok here's your bluescreen- *ERR_FILE_NOT_FOUND*
Its not working on windows 10 1511
Maybe it was fixed
Something interesting happens when doing this in VBox with EFI enabled:
I have a windows 10 host, testing this bug with a Windows 10 VM running off Vbox EFI (experimental I think).
The path crashed the VM as expected. Then the machine rebooted...
And a few seconds later my *HOST* BSODed from a VirtualBox driver exception... DRIVER_IRQL_NOT_LESS_OR_EQUAL....
0_0
Virtualbox bad
@@AhnafAbdullah you didn't try VirtualBox for yourself, did you?
I wanna know when the user is bsod but the file is still there, but the inside of it's just NUL. So the question is why my watch in some app it said NUL? Is may watch can BSOD to? (4:17)
this video is REALLY testing my curiosity
When I run the command all I get is “element not found”
type: "\\.\globalroot\device\condrv\kernelconnect" to broswer

@Executed you can legit just flash a new windows install, or you can boot off a usb, mount the old hard drive and recover files.
Or literally just remove it from startup in 15 seconds.
@Executed I tried it. It only BSODs and cleanly reboots.
EDIT: Tried it again, the issue is fixed, no more BSOD
how would it ruin someones career?
@@natew4724 what? what files would need to be recovered? its a bluescreen..
I just typed this on my laptop and it showed me a BSOD... i dunno what i was expecting
Maybe I'm doing something wrong or this bug was fixed
Note: This bug was fixed in the 2021-02 Cumulative Update.
Nooooo

Somehow the BSoD spread to my real pc when I ran it in VirtualBox :/

0:23 oh a windows insider build
2:44 Except I just did that (and opened it with chrome) and it worked.
Yeah Chrome doesn't protect img src values, shitty browser
So I never need to taskkill /im svchost.exe /f
@User Opening the directory doesn't need admin, but taskkill requires admin for that
*“Hey teacher I made this link for the class can you try it?”*
I don't know how most browsers and web tech works, but would it be possible to open this link using javascript or are file paths invalid redirects?
Hey Fly, I'm really curious about the crash that keep on occurring on loop which was not intended to when defender detected a threat or so.... Did you find the reason ?
When Defender finds the threat, it tries to access the directory the threat is detected from, since the directory is the crash dir, it will crash the system, my theory anyway.
I would be interested in a video that explores the consequences of changing the function to not require parameters, if that isn't how windows dealt with it.
You can't jeally just "make" a function not require parameters. You can try to catch the exception, but that also would literally just get rid of this one BSOD and nothing else
Basically, enter this path and condrv.sys breaks the system with an access violation.
Good Job, Windows 8.1, You Somehow Evaded The Crash.

I did it in a vm and it just froze and restarted then when it was loading up it said updating your system
This command said "Element not found" in Windows 11 (21H2), tried in CMD both normally and as Administrator
