It is a hardware device that enables the hacker to see individual data bytes in the network. It is used to capture data packet, decodes and analyzes the data. These devices can attach themselves at the hardware level and are used to monitor traffic. Hardware Protocol Analyzer:Ī protocol analyzer usually captures, analyzes the signal and data traffic in a network channel. There are various other packet sniffing tools such as EtherApe, Fiddler, OmniPeek, PRTG Network monitor, and so on. KisMac is used for MAC and OSX environments and works with any wireless card which supports raw monitoring mode. In simpler terms, Kismet is a network detector, packet sniffer, and intrusion detection system. Specifically used to sniff in wireless networks, even from hidden networks and SSIDs. NetworkMiner is one of the most commonly used tools that make network analysis simple, to detect host and open ports through packet sniffing. It is a set of password sniffing and network traffic analysis tools, used to sniff different protocols in UNIX and Linux systems only. Dsniffĭsniff was developed to parse different protocols and extract relevant information. It has lesser security risk and requires few resources only. Usually running under a command user interface, Tcpdump allows users to display TCP/IP and other packets being transmitted or being received over an attacked computer network. Wireshark is cross-platform and is extensively used to monitor network and packet flows in the network. These are open-sourced and widely used packet analyzers that are utilized for network troubleshooting, analysis, software, and communications protocol development. Various sniffing tools used currently and widely in the industry – Wireshark Join our CEH certification course online and become a professional certified Ethical Hacker! Tools used for Packet Sniffing Web password sniffing – HTTP sessions created by users are stolen by sniffers to get the user ID, password, and other sensitive information.Application-level sniffing – Applications running on the server are attacked to plan an application-specific attack.All details such as port number, service type, TCP sequence numbers, data are stolen by the hackers. TCP Session stealing – TCP session stealing is used to monitor and acquire traffic details between the source & destination IP address.ARP Sniff – ARP Poisoning attacks or packet spoofing attacks occur based on the data captured to create a map of IP addresses and associated MAC addresses. Different protocols such as ICMP, UDP, Telnet, PPP, DNS, etc., or other protocols might be used. Protocol Sniff – The sniffer attacks occur based on the network protocol used.A port-specific vulnerability attack happens in LAN sniffing. LAN Sniff – The sniffer attacks the internal LAN and scans the entire IP gaining access to live hosts, open ports, server inventory, etc.There are various types of sniffing attacks such as However, hubs hardly are used these days and hence passive sniffing attacks are barely reported. Contrary to active sniffing, here the hub can be directly injected with a sniffing device to easily extract the data packets. This kind of sniffing usually occurs at the hub. The redirected legitimate traffic finally allows the attacker to perform the sniffing of the traffic from the switch. Some of the examples of Sniffing attacks are:īroadly, sniffing attacks are classified into 2 categories: Active Sniffing attacksĪctive sniffing attacks majorly refer to attacks triggered by injecting Address Resolution Protocols (ARPs) into a network to flood the Switch Content address memory (CAM) table. There are different packet sniffers such as Wireshark, Dsniff, Etherpeek, etc. Unless the packets are encrypted with strong network security, hackers will be able to steal and access the data. They are called network protocol analyzers. The packet sniffers are the devices or media used to do this sniffing attack and capture the network data packets. The data packets are captured when they flow through a computer network. Sniffing attacks refer to data thefts caused by capturing network traffic through packet sniffers that can unlawfully access and read the data which is not encrypted.
