In-Reply-To: <EDA6886713F7F94081284F78EEB0B1B026DC7F () arvexc01 asiapacific cpqcorp net> Yet another way to detect sniffers on your network, specifically on Windows systems, is to scan for the presence of the WinPcap driver. Most of the freely available sniffers (L0phtcrack4.0, Ethereal, etc) use this driver, and you can scan for it using WMI or SCM queries.
Can somebody guide me on detecting a sniffer on my network. can i still=20 detect a sniffer even if the computer running the sniffer has disabled the=20 TCP/IP stack
Just out of curiosity, how would someone be able to sniff if they disabled the TCP/IP stack? Are you saying that they'd capture all ethernet frames, and then parse those apart? If the IP stack is disabled (and not replaced), then how would the IP packets be parsed, or passed up to the application layer? Also, I think moreso that "decompiling the kernel", someone would be more likely to patch it. --------------------------------------------------------------------------- Ethical Hacking at the InfoSec Institute.
