Dec 5, 2012 · If the system runs the sniffer, its interface will be in promiscuous mode. The test works like this: Send a ping with the correct IP address into the network but with a wrong mac address. The sniffing host will answer the ping packet, as it will receive every packet in promiscuous mode.

A sniffer (packet sniffer) is a device that intercepts data as it travels via a network. If computers are connected to a non-filtered or switched local area network, traffic can be broadcast to all computers in the same segment. This doesn't happen very often because computers are programmed to disregard all incoming and outgoing traffic from other...
Active and passive sniffing are the two types of sniffing. Active, as the name implies, entails some activity or involvement on the attacker's part to obtain information. In passive mode, the attacker lies inert and gathers information. Let's start with passive smelling.
This type of sniffing takes place at the hub. A hub is a device that receives traffic on a single port and then retransmit it to all other ports. It ignores the fact that the traffic is not intended for other destinations. If a sniffer device is positioned at the hub in this instance, the sniffer can directly record all network traffic. The sniffer...
In short, a switch learns a CAM table comprising the mac addresses of the destinations. The switch uses this table to determine which network packets should be forwarded. The sniffer will flood the switch with fraudulent requests during active sniffing, causing the CAM table to fill up. Once the CAM is full, the switch will act as a switch, transmi...
Passive smelling, as previously said, is extremely difficult to detect. Active sniffing is a little more evident, but you'll still need some technical know-how. You might operate your sniffer and monitor all DNS traffic in your network to detect any odd behavior if you feel there is a sniffer in your midst. Use the protection methods outlined above...
Sniffers are devices placed inside a network to intercept data and track what is communicated. You've probably seen at least one film in which a cunning investigator taps a suspect's phone line and listens in as they discuss various nefarious matters. Sniffers are similar to sniffers, but for the internet. The following is a list of people who migh...
