Hacking, Cracking and Attacking Tools

TOP 20 TOOLS:-

Nessus: The "Nessus" Project aims to provide to the internet community a free, powerful, up-to-date and easy to use remote security scanner for Linux, BSD, Solaris, and other flavors of Unix.

Ethereal: Ethereal is a free network protocol analyzer for Unix and Windows. Ethereal has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session.

Snort: Snort is an open source network intrusion detection system, capable of performing real-time traffic analysis and packet logging on IP networks.

Netcat: Netcat has been dubbed the network swiss army knife. It is a simple Unix utility which reads and writes data across network connections, using TCP or UDP protocol

TCPdump: TCPdump is the most used network sniffer/analyzer for UNIX. TCPTrace analyzes the dump file format generated by TCPdump and other applications.

Hping: Hping is a command-line oriented TCP/IP packet assembler/analyzer, kind of like the “ping” program (but with a lot of extensions).

DNSiff: DNSiff is a collection of tools for network auditing and penetration testing. dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, and webspy passively monitor a network for interesting data (passwords, e-mail, files, etc.).

GFI LANguard: GFI LANguard Network Security Scanner (N.S.S.) automatically scans your entire network, IP by IP, and plays the devil's advocate alerting you to security vulnerabilities.

Ettercap: Ettercap is a multipurpose sniffer/interceptor/logger for switched LAN. It supports active and passive dissection of many protocols (even ciphered ones)and includes many feature for network and host analysis.

Nikto: Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 2500 potentially dangerous files/CGIs, versions on over 375 servers, and version specific problems on over 230 servers.

John the Ripper: John the Ripper is a fast password cracker, currently available for many flavors of Unix.

OpenSSH: OpenSSH is a FREE version of the SSH protocol suite of network connectivity tools, which encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other network-level attacks.

TripWire: Tripwire is a tool that can be used for data and program integrity assurance.

Kismet: Kismet is an 802.11 wireless network sniffer - this is different from a normal network sniffer (such as Ethereal or tcpdump) because it separates and identifies different wireless networks in the area.

NetFilter: NetFilter and iptables are the framework inside the Linux 2.4.x kernel which enables packet filtering, network address translation (NAT) and other packetmangling.

IP Filter: IP Filter is a software package that can be used to provide network address translation (NAT) or firewall services.

pf: OpenBSD Packet Filter

fport: fport identifys all open TCP/IP and UDP ports and maps them to the owning application.

SAINT: SAINT network vulnerability assessment scanner detects vulnerabilities in your network's security before they can be exploited.

OpenPGP: OpenPGP is a non-proprietary protocol for encrypting email using public key cryptography. It is based on PGP as originally developed by Phil Zimmermann.
