[Release] sysCrasher

Or change the icon yourself with something like Resource Hacker.

Maybe put a less suspecting icon next time so we can troll noobs

If you want a custom icon, pm me so I can compile it for you

To put in in autostart on a school pc.

I like the way you think.

 

[RyDog]

Yeah, but that still shouldn't cause a BSoD, especially since svchost deals with handling network hosts. Watch it with a network monitor or verbose firewall and you'll see a lot of familiar outbound connections being made. For example, it handles Skype's binding of ports 80 and 443 and the associated traffic. Killing a process that has kernel hooks in place, however, would cause a BSoD (which is essentially a kernel panic).

Scvhost.exe doesn't just control networking.
These are all the scvhost.exe processes:

And this specific process is what causes the BSOD if you force close it:

Notice how it says (No Network)? This means these services that are being hosted by that process are services that don't require networking, but they host core Windows services.

Its like a shutdown shortcut...

But in style!

Presumably this requires admin privileges, though??

No. Drag and drop the EXE into the startup folder for the Start Menu. But doing so is retarded. Destructive malware never made sense to me. Data mining is much more practical.

Hmm I'm surprised that you can kill tasks without admin privileges. Seems like a major security flaw

If you replace this with a autostart app that presumably needs admin privileges like cmd or sticky keys (anything in the system32 directory), yes this doesn't require admin privileges. But if you put it in the autostart directory where Windows automatically runs installed programs, no they don't have admin privileges. I tried doing this on another local account and it don't autostart so I'm assuming it doesn't work.
Any ways, I created a bomb that duplicates itself rapidly to suck your PC's resources dry and since there are so many processes of it duplicating, it's impossible to cancel without rebooting or waiting for the script to crash Windows. Anyone interested?
EDIT: My antivirus picked this up as a trojan so I don't think I should share it here...

 

[mgrev]

For fun, maybe?

If you want fun, make this progran start on boot on a friends pc. (Fixable by booting something like a linux distro and deleting the program)

Did it give you a error or did you deny the admin access?

Ran as admin, didn't work, I have UAC turned off btw

Does CMD pop up at all? If it does, what shows up on the command line?

 

[Dr.Hacknik]

Hehe, put it in the Startup folder (Or Autostart) of a School PC, and have it crash the PC once you login....

CMD pops up for a second and closes

No i tried that already... It doesn't crash since it requires admin. I did make a new script that loops and creates a 'buffer overflow' that causes your computer to run out of resources and crash. It doesn't require any admin privileges but my antivirus picks it up as a Trojan... Would you like it?

Shift + right click in the location of sysCrasher and click on the option called 'open command prompt here' and then type in sysCrasher.exe and send it and then tell me what command prompt tells you.

A buffer overflow is when you overflow the buffer to the point where code can be executed out of the stack. What you have would technically be called a local DoS.

It does overwrite some memory locations since it overwrote my GPU's process and cause all the text to mess up and scaled my resolution down to as low as possible, but this couldve been because my GPU crashed.
