Hello, I think I'm victim of DoS. I'll explain you why I think that below.
First, you must know that the problem is on my personal device. I use it at home and at work and I have the problem in both places.
The problem is that I'm receiving a lot of packets, even though I'm doing absolutely nothing on my laptop.
You cand find a capture I've done on my PC for 1 hour while I was doing nothing (the only application that was open on my laptop was wireshark) there
So, on this capture, my private IP adress is 192.168.1.24 and you can see that I'm continually receiving packets from various IP adresses. When you search on the Internet who owns these adresses, you discover that they come from various companies, mostly companies that provide cloud services, such as Akamai, Cloudflare, Fastly, etc.
Generally, between the reception of these packets, I also receive many packets using the SSDP protocol. I'm not sure if this is linked and I'm genuinely surprised there's no trace of it in this capture.
I want to insist on the fact that I've received all these packets while only wireshark was running. Because of that, my laptop has received 15 Go of data in 2 days with wifi, altough I've just sent 2 emails... It's clearly not normal.
Don't hesitate to let me know what you think and and how you think I can stop being flooded. Thanks in advance!
