Packet Sniffer Detection with AntiSniff
Ryan Spangler · 2003
Packet sniffing is a technique of monitoring every packet that crosses the network. A packet sniffer is a piece of software or hardware that monitors all network traffic. The security threat presented by sniffers is their ability to capture all incoming and outgoing traffic, including clear-text passwords and usernames or other sensitive material. While packet sniffers can be fully passive, some aren’t, therefore they can be detected. This paper discusses the different methods that AntiSniff uses to detect these sniffing programs.
