Installing Nessus on Backtrack 4

Here is an easy to follow tutorial on installing nessus on the Backtrack 4 Pre Release. This is courtesy of secure_it at the remote-exploit forums.

First download these packages


Nessus-3.2.1-ubuntu804_i386.deb
NessusClient-3.2.1-debian4_i386.deb


(I have chosen debian package because NessusClient-3.2.1.1-ubuntu804.i386.deb was missing some of dependencies and was not installing correctly.instead the debian package worked like a charm as its upto-date with dependencies and it produces no error at all.


Next register your copy to get plugins update using homefeed and please provide the real mail ID as they will send you the activation key for homefeed.

now configure the certificate & admin user for nessus

(configure options accordingly or just press enter for default)

CA certificate life time in days [1460]:

Cracking OS X Lion Passwords

UPDATE [2011-10-15]: The issues described in this post have now been resolved by Apple. Users running OS X Lion 10.7.2 or security update 2011-006 are no longer affected by the vulnerabilities detailed below (CVE-2011-3435 and CVE-2011-3436). For further details on this security update please see Apple's advisory . In 2009 I posted an article on Cracking Mac OS X passwords . Whilst this post has been quite popular, it was written for OS X 10.6 and prior. Since the release of Mac OS X Lion (10.7) in July, I have received numerous requests for an update. Typically, I would have just updated the existing article without the need for a new post. However, during my research I discovered something interesting about OS X Lion that I'd like to share. In previous versions of OS X (10.6, 10.5, 10.4) the process to extract user password hashes has been the same: obtain the user's GeneratedUID and then use that ID to extract hashes from a specific user's shadow file (See my pr

Cracking Mac OS X Passwords

In this post I will demonstrate how to both extract and crack Mac OS X passwords. The OS X variants that this tutorial is aimed at are 10.4 (Tiger), 10.5 (Leopard) and 10.6 (Snow Leopard). Whilst Mac OS X is based on a Unix variant (BSD), there are several key differences between traditional Unix-based and Mac OS systems when it comes to password storage. Lets take a quick look at some of the differences. If you have ever poked around on an OS X system, you may have noticed the absence of the /etc/shadow file. Whilst traditional Unix and BSD variants store their password hashes in /etc/shadow and /etc/master.passwd respectively, Mac OS X does not. Since the release of OS X 10.3 in 2003, Macintosh products have stored their shadow files in the /var/db/shadow/hash/ directory. Another key difference is the way in which the two systems store their hashes. On a Unix-based system, every hash associated with the system is stored in the /etc/shadow file. This differs from OS X whereby each

Metasploit Autopwn: Hacking made simple

Image
Nowadays, exploiting a system requires little, if no knowledge of computer systems or networking. Merely, someone with 10 minutes on their hands that is interested enough to Google how it’s done. One with very little skills has the ability to fire up Metasploit, load an exploit, and fire it at the target system – giving attacker’s the ability to compromise a system within minutes. I thought I would write a post on Metasploit’s autopwn module to reiterate just how simple it is to attack/compromise a system in today’s environment. My intentions here are to give you a tutorial on the Metasploit autopwn module and provide a timely reminder on just how important it is to have a good patch policy in place. I would also recommend regular audits on system services. The tools I will be using in this tutorial are: Nessus - A free vulnerability scanner for Mac OS, Windows and Linux Metasploit – framework 3 - A free exploit framework for launching exploits against targets A virtual machine runni
