I have multiple devices - a Samsung and a Lenovo tab, an Amazon Alexa, an HP laptop running Windows 7, and another running Windows 10. Bored, I tried to DoS my Windows 10 laptop using my Windows 7 laptop. I did it using a batch file with the ping command, like so:
:loop ping 192.168.0.1 -l 65500 -w 100 -n 1 goto :loop
A very primitive and basic way of trying it indeed. So I open about 30 command prompts running the same batch file all at once. This method worked quite well for my TP-Link router and other devices mentioned above, except for my Windows 10 laptop. It seems to have some sort of protection against the attack. It was quite literally unaffected.
Note that I was on the same network and did it using my Windows 7 laptop, and attacking the router cut off internet access for all other devices on the network as well.
Why exactly did this work on other devices, and not specifically on Windows 10?
What firewall rules and other mitigation measures does Windows 10 have in the above example that rendered it virtually immune to this simple yet effective DoS?
