Hello. I am trying to pin down Keyboard keystroke problems and looking at a possible key logger. Key strokes are missed on random computers by random users with random keyboards and random Windows OS. Running wire shark, I am not sure what to look for on the report output. Thank you.
There are so many ways in which a keylogger can exfiltrate data that it's impossible to give a specific answer. Any (meta-)data carrying protocol is a candidate, e.g., HTTP URL, HTTP header, IRC, SMTP, FTP, you name it. It would require detailed analysis of all communications to see if something cannot be identified as expected/valid traffic, something that may prove difficult in even normal networks.
On the other hand, it would be rather strange if a keylogger would cause keystrokes to be dropped, and thereby attracting attention to itself...
Hello. Do you happen to know of any "out of the ordinary" reasons key strokes would randomly not hit? We have tried a wide Varity of solutions to no avail...from hard replacement to software removals to driver updates...etc..
That is not a Wireshark question, I'm afraid.
