I am making an Honeypot right now in golang that reports IPs (ipabusedb) when they access unauthorized an port ex: UDP/37810. Now to my problem how do I listen to every udp port easy? I dont want to make 65500 sockets for each udp/tcp port… Continue reading Golang Honeypot (Detecting unauthorized connections to ports tcp/udp)
Is it possible to spoof the IP once a TCP handshake was performed successfully?
For example:
Perform the handshake
Use the session with the same IP which performed handshake but on
different machine and network then send a request e.g PO… Continue reading Spoof IP address after a TCP handshake established
I have a question for my security class related to the TCP handshake. The question is:
A hacker just set up a TCP connection with a web server in Chicago, Illinois, claiming he is coming in with a source IP address that
clearly belongs to… Continue reading Speed of TCP handshake to prove an IP is spoofed [closed]
For some experiments I have conducted using the Mininet SDN, I test with varying network parameters — specifically in my case, network link delay and packet loss.
However, the feasibility of my experiments involving these parameters truly… Continue reading How is latency (link delay) and packet loss (network jitter) implemented in Mininet? Are they realistic? [closed]
There is a small piece of code that is making request to Web server through socket. i am able to see that its a TCP over no SSL through wireshark.
My question is, Is it technically possible to see contents of TCP packets? All communication… Continue reading Decoding TCP Packet in wireshark
I want to use the openvpn client on my Ubuntu 20.10 to connect to ExpressVPN’s VPN.
Unfortunately I have to use the TCP ports, as the UDP ports are blocked.
ExpressVPN’s website only allows to download configuration files for UDP port.
How… Continue reading Configure openvpn for ExpressVPN TCP ports [migrated]
An application is running in a customer’s environment on a single server and consists of a collection of Windows Services that communicate with each other using (unencrypted) TCP messages.
Although these messages can’t be viewed across the… Continue reading IPC Security on Server
There’s more to a primitive under the surface, and once we discover what it’s actually doing, it opens up a whole new way for us to inspect and filter packets.
Lets use the TCP primitive as an example. What is it actually doing? How does it show us o… Continue reading Pcaps and the Tools That Love Them Part 2 of ???
How do sequence numbers and timeouts provide a reliable channel for application-layer data?
I’m looking for existing tools, at best with a Python-API, which would allow me to silently intercept an established TCP connection for which the following assumptions hold:
All IP packets of the TCP-stream are routed through my node; the… Continue reading Tool for Special-Case Interception of established TCP-connection
