1. Nmap

I think everyone has heard of this one, recently evolved into the 4.x series.

Nmap (“Network Mapper”) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source.

Can be used by beginners (-sT) or by pros alike (–packet_trace). A very versatile tool, once you fully understand the results.

2. Nessus Remote Security Scanner

Recently went closed source, but is still essentially free. Works with a client-server framework.

Nessus is the world’s most popular vulnerability scanner used in over 75,000 organizations world-wide. Many of the world’s largest organizations are realizing significant cost savings by using Nessus to audit business-critical enterprise devices and applications.

3. John the Ripper

John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), DOS, Win32, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix flavors, supported out of the box are Kerberos AFS and Windows NT/2000/XP/2003 LM hashes, plus several more with contributed patches.

You can get JTR Here

4. Nikto

Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 3200 potentially dangerous files/CGIs, versions on over 625 servers, and version specific problems on over 230 servers. Scan items and plugins are frequently updated and can be automatically updated (if desired).

Nikto is a good CGI scanner, there are some other tools that go well with Nikto (focus on http fingerprinting or Google hacking/info gathering etc, another article for just those).

Get Nikto Here

Also see – Nikto 2.1.0 Released – Web Server Security Scanning Tool.

5. SuperScan

Powerful TCP port scanner, pinger, resolver. SuperScan 4 is an update of the highly popular Windows port scanning tool, SuperScan.

If you need an alternative for nmap on Windows with a decent interface, I suggest you check this out, it’s pretty nice.

Get SuperScan Here

6. p0f

P0f v2 is a versatile passive OS fingerprinting tool. P0f can identify the operating system on:

– machines that connect to your box (SYN mode),
– machines you connect to (SYN+ACK mode),
– machine you cannot connect to (RST+ mode),
– machines whose communications you can observe.

Basically it can fingerprint anything, just by listening, it doesn’t make ANY active connections to the target machine.

Also see – p0f – Advanced Passive OS Fingerprinting Tool.


7. Wireshark (Formely Ethereal)

Wireshark is a GTK+-based network protocol analyzer, or sniffer, that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and to give Wireshark features that are missing from closed-source sniffers.

Works great on both Linux and Windows (with a GUI), easy to use and can reconstruct TCP/IP Streams! Will do a tutorial on Wireshark later.

Get Wireshark Here

Also see – Wireshark 1.2.1 Released – Network Protocol Analyzer.

8. Yersinia

Yersinia is a network tool designed to take advantage of some weakeness in different Layer 2 protocols. It pretends to be a solid framework for analyzing and testing the deployed networks and systems. Currently, the following network protocols are implemented: Spanning Tree Protocol (STP), Cisco Discovery Protocol (CDP), Dynamic Trunking Protocol (DTP), Dynamic Host Configuration Protocol (DHCP), Hot Standby Router Protocol (HSRP), IEEE 802.1q, Inter-Switch Link Protocol (ISL), VLAN Trunking Protocol (VTP).

The best Layer 2 kit there is.

9. Eraser

Eraser is an advanced security tool (for Windows), which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. Works with Windows 95, 98, ME, NT, 2000, XP and DOS. Eraser is Free software and its source code is released under GNU General Public License.

An excellent tool for keeping your data really safe, if you’ve deleted it..make sure it’s really gone, you don’t want it hanging around to bite you in the ass.

Get Eraser Here.

10. PuTTY

PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an xterm terminal emulator. A must have for any h4x0r wanting to telnet or SSH from Windows without having to use the crappy default MS command line clients.

Get PuTTY Here.


11. LCP

Main purpose of LCP program is user account passwords auditing and recovery in Windows NT/2000/XP/2003. Accounts information import, Passwords recovery, Brute force session distribution, Hashes computing.

A good free alternative to L0phtcrack.

LCP was briefly mentioned in our well read Rainbow Tables and RainbowCrack article.

Get LCP Here

Also see – LCP – A Good FREE Alternative to L0phtcrack (LC5).

12. Cain and Abel

My personal favourite for password cracking of any kind.

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.

13. Kismet

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.

A good wireless tool as long as your card supports rfmon (look for an orinocco gold).

14. NetStumbler

Yes a decent wireless tool for Windows! Sadly not as powerful as it’s Linux counterparts, but it’s easy to use and has a nice interface, good for the basics of war-driving.

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:

  • Verify that your network is set up the way you intended.
  • Find locations with poor coverage in your WLAN.
  • Detect other networks that may be causing interference on your network.
  • Detect unauthorized “rogue” access points in your workplace.
  • Help aim directional antennas for long-haul WLAN links.
  • Use it recreationally for WarDriving.

15. hping

To finish off your download hacking tools mission, something a little more advanced if you want to test your TCP/IP packet monkey skills.

hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to the ping unix command, but hping isn’t only able to send ICMP echo requests. It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features.

Some Good Tips to Secure Linux

Outsmart Malicious Hackers


I came across this while browsing, has some pretty solid stuff, goes deeper than most basic Linux security guides.

It has some good sections like this on protection against fork bombs:

Fork bombs are programs that keep creating child processes until system resources are all used, they actually aren’t remote exploits because they require a local user to execute the bomb, however, users may be tricked into running a fork bomb, for example the following example may look innocent, but running it on an unprotected system may take the whole system down:

:( ){ : |:& }; :

WARNING: do NOT run the above code on an unprotected system!

The above shell script will actually keep forking at an exponential rate until system resources are exhausted.

To protect a system against such attacks, there is a file for limiting the number of processes for each user, it is /etc/security/limits.conf, add the following two lines to it:
@users soft nproc 100
@users hard nproc 150

The lines prevent anyone in the users group from having more than 150 processes, and issue a warning at 100 processes.

Your system may not have a users group, so you may need to edit the lines to suit your needs.

There are some other things you can do like using a file integrity checker, installing a log checker or centralising logs with something like syslog-ng, scanning for SU files on a regular basis, setup alerts if a new user is added and so on, but this gives you a start.

It has some security tips for OpenSSH, Samba and MySQL too.

I recommend taking a look anyway!

British Hacker Gary McKinnon Fears Guantanamo

Keep on Guard!


I don’t know what he was thinking really, tampering with US military or governmental systems without some SERIOUS protection.

A British man accused of being behind the largest ever hack of US government computer networks could end up at Guantanamo Bay, his lawyer has claimed.

Gary McKinnon, from London, denies causing $700,000 (£400,000) damage to military and Nasa systems in 2001-2.

Bow Street Magistrates’ Court was told the 40-year-old feared a prosecution might take place under US anti-terror laws if it agreed to his extradition.

Jailed under the anti-terror laws, a little extreme for hacking no?

It’s not like he’s the member of an opposing countries cyber attack squad.

What’s worse is if he’s subjected to Military Order Number One – a legal procedure which enables the president to specify that suspects can be detained indefinitely..

If he gets that, well he’s basically screwed.

Mr McKinnon is accused of hacking into computers in 14 states, including at the Pentagon and naval weapon station Earle.

At an earlier hearing his lawyers suggested his actions were not malicious – he had been trying to expose lax computer security and access what he believed was withheld information about UFOs.

It seems to be pretty sensationalist though, from what I know he used some pretty standard out of the box tools to hack into some poorly secured peripheral systems. He was trying to expose the flaws rather than use them for some malicious purpose.

But well, the lesson is there, don’t mess with things you shouldn’t..and if you HAVE to, cover your tracks ;)

I also found a VERY interesting interview with McKinnon over here.

New Critical MEGApatch fixes 10 Vulnerabilities in Internet Explorer

Keep on Guard!


Well how many does that leave unpatched? 30+ if I remember correctly from the PivX page that got taken down mysteriously.

Microsoft on Tuesday released a “critical” Internet Explorer update that fixes 10 vulnerabilities in the Web browser, including a high-profile bug that is already being used in cyberattacks.

The Redmond, Wash., software giant sent out the IE megafix as part of its monthly Patch Tuesday cycle of bulletins. In addition, Microsoft delivered two bulletins for “critical” Windows flaws, one for an “important” vulnerability in Outlook Express and one for a “moderate” bug in a component of FrontPage and SharePoint.

I think this whole Patch Tuesday is a stupid idea in itself, why can’t they release patches for critical vulnerabilities ASAP?

Some pretty scary news though eh? For normal users anyway.

Eight of the 10 vulnerabilities repaired by the IE update could be abused to gain complete control over a Windows computer running vulnerable versions of the Web browser.

Apparently they say, only one has been used…the one we talked about previously (The CreateTextRange Exploit).

According to Microsoft’s bulletin, three of the 10 vulnerabilities fixed by the update had been publicly disclosed. Only the CreateTextRange flaw was being exploited in attacks, the software maker said.

Basically you can get complete control of the machine just by getting a user to visit a maliciously built web page, good stuff!
