![]() dnsspoof: Forge replies to arbitrary DNS address / pointer queries on the LAN.fragrouter :-) must be turned on ahead of time. kernel IP forwarding (or a userland program which accomplishes the same, e.g. This is an extremely effective way of sniffing traffic on a switch. arpspoof ( ARP spoofing): Redirect packets from a target host (or all hosts) on the LAN intended for another local host by forging ARP replies. ![]() This text belong to theĭsniff “README” written by the author, Dug Song. This is a list of descriptions for the various dsniff programs. To learn more about using dsniff, you can explore the Linux man page. The man page for dsniff explains all the flags. etc/dsniff/dsniff.magic Network protocol magic /etc/dsniff/rvices Default trigger table If no host file is specified, replies will be forged for all address queries on the LAN with an answer of the local machine’s IP address. These are the files that are configured in dsniff folder /etc/dsniff/ /etc/dsniff/dnsspoof.hosts Sample hosts file. Its man page explains that Dug Song wrote dsniff with "honest intentions - to audit my own network, and to demonstrate the insecurity of cleartext network protocols." He then requests, "Please do not abuse this software." The "dsniff" tool decodes passwords sent in cleartext across a switched or unswitched Ethernet network. The name "dsniff" refers both to the package as well as an included tool. It handles FTP, Telnet, SMTP, HTTP, POP, poppass, NNTP, IMAP, SNMP, LDAP, Rlogin, RIP, OSPF, PPTP MS-CHAP, NFS, VRRP, YP/NIS, SOCKS, X11, CVS, IRC, AIM, ICQ, Napster, PostgreSQL, Meeting Maker, Citrix ICA, Symantec pc Anywhere, NAI Sniffer, Microsoft SMB, Oracle SQL*Net, Sybase and Microsoft SQL protocols. As the name implies, dsniff is a network sniffer, but it can also be used to disrupt the normal behavior of switched networks and cause network traffic from other hosts on the same network segment to be visible, not just traffic involving the host dsniff is running on. The applications sniff usernames and passwords, web pages being visited, contents of an email, etc. sshmitm and webmitm implement active man-in-the-middle attacks against redirected SSH and HTTPS sessions by exploiting weak bindings in ad-hoc PKI. arpspoof, dnsspoof, and macof facilitate the interception of network traffic normally unavailable to an attacker (e.g., due to layer-2 switching). dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, and webspy passively monitor a network for interesting data (passwords, e-mail, files, etc.). DSniff is a set of password sniffing and network traffic analysis tools written by security researcher and startup founder Dug Song to parse different application protocols and extract relevant information.
