A packet sniffer, or network sniffer, is a program that monitors the network activity flowing over a computer down to an individual packet level. Microsoft has quietly added a built-in network packet sniffer to the Windows 10 October 2018 Update, and it has gone unnoticed since its release. This program will simply listen to connections on port 3040 and print the string received shell32.dll. So, overall, after checking the relevant kernel parameters, no problem was actually found. Finally, it is clear that the problem is caused by the rcvbuf value being set too small on the Web server. After adjusting the parameters, the upload speed was significantly improved.

It needs to adapt the value based on the delay that it experiences in the network. This would allow a maximum TCP Window of 8 Megabytes. The window scaling option tells the peer that the receive window value found in the TCP header should be scaled by the given number to get the real size. a timer on the receiver should send an ACK for the latest data if it has not been acked within about 20ms. By opening many connections of this nature to a server, the attacker consumes all of the space in the server’s TCP connection table , preventing legitimate users from establishing a connection. Alternately, the attacker can open many connections with a very small (around 4-byte) window size, forcing the server to break up information into a massive number of tiny 4-byte chunks. Many connections of this type will consume a server’s available memory, also causing a denial-of-service.
