I’m using two routers in my home network, as described in this question (router B in the diagram). Therefore, router B is not accessible from the internet.
Going over the logs of this router, I was surprised to find what is logged as "… Continue reading How can a SYN flood affect a router in this scenario?
In a hping3 SYN flood attack with random sourced spoofed IP addresses in a VM, wireshark shows no SYN ACK’s. Is that normal?
There were about 28000+ packets sent in less than 1 minute. All in all about 500000 packets were sent (luckily the… Continue reading SYN flood with spoofed IP addresses but no SYN ACK [closed]
A new study claims that in the next 80 years, the global land area exposed to coastal flooding as a result of climate change is set to increase by roughly 50 percent, threatening tens of millions of people, and up to 20 percent of global GPD. The autho… Continue reading Coastal flooding could put 20 percent of global GDP at peril
I am a new programmer. I made a SYN Flood program. I observed many packets with Wireshark. But I don’t know how many megabytes there were.
I don’t know how many packets are going to the target in a healthy way.
Is there a test platform… Continue reading SYN Flood Test Platform [closed]
I used hping3 to stress test a web app (DoS):
sudo hping3 -S –flood -V -p 80 [IP addr/url]
When I attempted to get access to the target web application through my network, it refused to connect with the error
This site can’t be reac… Continue reading Why does hping3 test DoS not successfully?
I’m studying Dos attacks and in particular the syn flood one.
I’m replicating the attack on local Debian VMs.
Attack VM:

I have a virtual environment and I am making a SYN flood attack to a Ubuntu Server’s port 53 using Kali 2020.
I realized that a countermeasure for this attack is to limit or block the responses to the SYN packets, which are the SYN,ACK.

Just for fun, I’ve ping flooded my bluetooth speaker at home using l2ping on Linux and I was unable to connect to it as the pinging continued. I’ve tried flooding my phone and it seems to have received the packets as I got a response (just… Continue reading Why are some Bluetooth devices susceptible to ping floods and some are not?
Fighting against a large SYN Flood attack that is happening every 2 minutes repeatedly.
During attack, number of syn-rcv is between 290-550
