Top 10 Hacker Attack Tools Computer security "agents" must master the same tools used by the hackers they seek, and many of these programs are available to download for free. The man-in-the middle attack, (also known as the monkey-in-the middle) is a useful method of scanning network data and extracting what is known as interesting data, (passwords, e-mail, data files). Listed below you will find 10 programs used to assault and defend networks around the world. 1. Ethereal is the most
widely used network protocol analyzer in the world. Ethereal is a
multi-platform sniffer that captures data packets on a wired LAN or a
Wireless network. Ethereal can capture up to 683
protocols. 2. DSniff is a suite of
programs that can be used in auditing and penetration testing. (Wired
network or wireless.) dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf and
webspy monitors networks for interesting data (e-mail, files, and
passwords). Arpspoof, dnsspoof, and macof intercepts network traffic. All
of these tools facilitate the man-in-the middle attack against networks.
(Also known as monkey-in-the middle) 3. Ettercap is a suite
for man in the middle attacks on LAN. It features sniffing of live
connections, content filtering on the fly and many other interesting
tricks. It supports active and passive dissection of many protocols (even
ciphered ones) and includes many feature for network and host
analysis. 4. Kismet is an 802.11
layer2 wireless network detector, sniffer, and intrusion detection system.
Kismet will work with any wireless card which supports raw monitoring
(rfmon) mode, and can sniff 802.11b, 802.11a, and 802.11g
traffic. 5. NetStumbler is a tool
for Windows that allows you to detect Wireless Local Area Networks (WLANs)
using 802.11b, 802.11a and 802.11g. It has many
uses: 6. AirSnort is a wireless
LAN (WLAN) tool which recovers encryption keys. AirSnort operates by
passively monitoring transmissions, computing the encryption key when
enough packets have been gathered. 802.11b, using the Wired Equivalent
Protocol (WEP), is crippled with numerous security
flaws. 7. Cain &
Abel is a password recovery tool for
Microsoft Operating Systems. It allows easy recovery of various kind of
passwords by sniffing the network, cracking encrypted passwords using
Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP
conversations, decoding scrambled passwords, revealing password boxes,
uncovering cached passwords and analyzing routing protocols. The program
does not exploit any software vulnerabilities or bugs that could not be
fixed with little effort. It covers some security aspects/weakness present
in protocol's standards, authentication methods and caching mechanisms;
its main purpose is the simplified recovery of passwords and credentials
from various sources, however it also ships some "non standard" utilities
for Microsoft Windows users. 8. EtherApe is a
graphical network monitor for Unix modeled after etherman. Featuring link
layer, ip and TCP modes, it displays network activity graphically. Hosts
and links change in size with traffic. Color coded protocols display. It
supports Ethernet, FDDI, Token Ring, ISDN, PPP and SLIP devices. It can
filter traffic to be shown, and can read traffic from a file as well as
live from the network. 9. Netcat: The network
swiss army knife A simple Unix utility which reads and writes data across
network connections, using TCP or UDP protocol. It is designed to be a
reliable "back-end" tool that can be used directly or easily driven by
other programs and scripts. At the same time, it is a feature-rich network
debugging and exploration tool, since it can create almost any kind of
connection you would need and has several interesting built-in
capabilities. 10. PsTools is a set of command line utilities that allow you to manage local and remote systems.
