Passive Sniffing It is called passive because it is difficult to detect “ Passive sniffing” means sniffing through a hub Attacker simply connects the laptop to the hub and starts sniffing

The Dude Sniffer Developed by Mikro Tik, the Dude network monitor is a new application which can improve the way you manage your network environment Functions: Automatically scans all devices within specified subnets Draws and lays out a map of your networks Monitors services of your devices Alerts you in case some service has problems It is written in two parts: Dude Server, which runs in a background Dude Client, which may connect to local or remote dude server Įthereal Ethereal is a network protocol analyzer for UNIX and Windows It allows the user to examine data from a live network or from a capture file on a disk The user can interactively browse the captured data, viewing summary and detailed information for each packet captured ĭisplay Filters in Ethereal Display filters are used to change the view of packets in captured files Display Filtering by Protocol Example: type the protocol in the filter box arp, http, tcp, udp, dns Filtering by IP Address ip.addr = 10.0.0.4 Filtering by multiple IP Addresses ip.addr = 10.0.0.4 or ip.addr =10.0.0.5 Monitoring Specific Ports tcp.port=443 ip.addr=192.168.1.100 machine ip.addr=192.168.1.100 & tcp.port=443 Other Filters ip.dst = 10.0.1.50 & frame.pkt_len > 400 ip.addr = 10.0.1.12 & icmp & frame.number > 15 & frame.number ip.src=205.153.63.30 or ip.dst=205.153.63.30 Protocols Vulnerable to Sniffing Protocols that are susceptible to sniffers include: Telnet and Rlogin : Keystrokes including user names and passwords HTTP : Data sent in clear text SMTP : Passwords and data sent in clear text NNTP : Passwords and data sent in clear text POP : Passwords and data sent in clear text FTP : Passwords and data sent in clear text IMAP : Passwords and data sent in clear text

Objective Sniffing Protocols vulnerable to sniffing Types of sniffing ARP and ARP spoofing attack Tools for ARP spoofing MAC flooding Tools for MAC flooding Sniffing tools Types of DNS poisoning Raw sniffing tools Detecting sniffing Countermeasures ĭefinition: Sniffing A program or device that captures vital information from the network traffic specific to a particular network Sniffing is a data interception technology The objective of sniffing is to steal: Passwords (from email, the web, SMB, ftp, SQL, or telnet) Email text Files in transfer (email files, ftp files, or SMB)
