This video will show you how to create a reverse SSH connection to a server/workstation

This exploit is taking advantage of vulnerability MS08-067 using Metasploit on Kali.
This is a Kali VM attacking a Microsoft 2008 server (this will also work on any machine without the patch)

The moral of this is to update your system

The official update from BackTrack Central:

Seven years of developing BackTrack Linux has taught us a significant amount about what we, and the security community, think a penetration testing distribution should look like. We’ve taken all of this knowledge and experience and implemented it in our “next generation” penetration testing distribution.

After a year of silent development, we are incredibly proud to announce the release and public availability of “Kali Linux“, the most advanced, robust, and stable penetration testing distribution to date.

Kali is a more mature, secure, and enterprise-ready version of BackTrack Linux. Trying to list all the new features and possibilities that are now available in Kali would be an impossible task on this single page. We therefore invite you to visit our new Kali Linux Website and Kali Linux Documentation site to experience the goodness of Kali for yourself.

We are extremely excited about the future of the distribution and we can’t wait to see what the BackTrack community will do with Kali. Sign up in the new Kali Forums and join us in IRC in #kali-linux on irc.freenode.net and help us usher in this new era.

How secure are your passwords? Hopefully they’re more clever than these top 25 most-popular (and therefore least secure) passwords.

SplashData, an online security management firm, compiled this list for 2012:

  1. password
  2. 123456
  3. 12345678
  4. qwerty
  5. abc123
  6. monkey
  7. 1234567
  8. letmein
  9. trustno1
  10. dragon
  11. baseball
  12. 111111
  13. iloveyou
  14. master
  15. sunshine
  16. ashley
  17. bailey
  18. passw0rd
  19. shadow
  20. 123123
  21. 654321
  22. superman
  23. gazwsx
  24. michael
  25. football

Are any of your passwords on the list? If so, it’s time to upgrade to one with varying numbers, capitalization and figures. Separate words with spaces or underscores. For crying out loud, don’t use your pet’s or your spouse’s name or even you children’s names.

Since the release of Windows 8 I am constantly asked “Where is this function, it is in Windows 7″. Well here is a quick way to find all the functions and features of Windows 8.

First off after you have booted Windows 8 and logged in select ‘Desktop’

godmode 1

Right click on the desktop and select ‘New>Folder

godmode 2

After the folder has been created, copy the below text, rename that folder, and paste the text as the file name.

GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}godmode 3

Once the above steps have been completed a new shortcut entitled GodMode will be visible. Opening this shortcut will display a Window similar to the below example.

godmode 4

Now you have all the power of the Gods.

Computational Engineers at the University of Southampton have built a supercomputer from 64 Raspberry Pi computers and Lego.

The machine, named “Iridis-Pi” after the University’s Iridis supercomputer, runs off a single 13 Amp mains socket and uses MPI (Message Passing Interface) to communicate between nodes using Ethernet.

The whole system cost under £2,500 (excluding switches) and has a total of 64 processors and 1Tb of memory (16Gb SD cards for each Raspberry Pi). Professor Cox uses the free plug-in ‘Python Tools for Visual Studio’ to develop code for the Raspberry Pi.

“The team wants to see this low-cost system as a starting point to inspire and enable students to apply high-performance computing and data handling to tackle complex engineering and scientific challenges as part of our on-going outreach activities,” says prof. James Cox.

What is a Raspberry Pi?

 

 

Hard disk failure is possibly the worst thing that can happen to your computer and it often occurs without giving any warning signs.

Test Your Hard Drive for Impending Problems

You may however run certain tests on your computer beforehand to get an idea about the current condition of your hard disk. This should  in turn help you decide whether a replacement drive is necessary or not.

Step 1: Check your hard disk for errors

All recent versions of Windows include a utility called Chkdsk.exe that can check your hard disk for any bad sectors.

You may either run Chkdsk from the command line (see details) or launch Windows Explorer, right click the drive that you wish to examine and choose Properties. Switch to the Tools tab and click the “Check Now” button under Error checking. Select “Scan for and attempt recovery of bad sectors” to perform a thorough disk check.

Step 2: Understand the sounds of your disk

Do you sometimes hear strange sounds coming out of the CPU box? Well, if the hard drive is making those sounds, it could be an alarming situation and your best bet would be that you turn off the computer before any further damage is done to the disk.

But how do you distinguish between sounds coming from a hard disk with noise that’s made by the fans or the power supply? Here’s a useful page where you can listen to recorded sounds of various hard drives that have lead to a crash. If your disk is making a similar sound, get a replacement quickly.

Step 3: Catch errors before they happen

Disk Checkup is a free hard disk monitoring utility that displays tons of diagnostic data about your disk. While the level of detail it provides may easily confuse even tech-savvy users, just ignore the numbers and keep the utility running in the background.

It monitors your disk’s temperature, read and write error rate, etc. and will alert you when the values of any of these parameters approach dangerous levels. These may be signs of an impending disk failure. Disk Checkup is free for personal use.

Step 4: Thoroughly test your Hard Disk

SeaTools is free diagnostic tool that can completely test your hard drive regardless of the OS installed on it. The tool is provided by Seagate but it works with non-Seagate   disk drives as well.

To get started, you need to download the ISO image of SeaTools for DOS and create a bootable CD. Now boot the computer with the CD in the drive, accept the license agreement and run a long test (the full scan). If any defects are found, a list will be offered at the end or after aborting the disk scan.

Other computer vendors /disk manufactures including Samsung, Hitachi, Toshiba (Fujitsu), Western Digital, Lenovo, Dell, etc.  too offer diagnostic tools that work only with their own brand of hard drives. If you are having frequent computer problems (like system hangs or fails to boot up), you may run these tools to confirm if the problems are hard drive related
