Using Your Linux Computer As A Media Center (Part 1) If you are a Windows or Mac user, you will be familiar with Windows Media Center or Front Row that both have the ability to turn your computer into a Media Center PC. Linux users don’t have such luck as most distros do not come with a media center application pre-installed. If you are like me who is a Linux user and owns a huge collection of music, videos and pictures, the world is not over for you yet. There are many open-source applications that you can use to turn your Linux machine into a lean, mean media center. In part one of this series, I will go through some of these free media center software that you can use in your Linux machine (also see Media Center alternatives for Windows). XBMC is by far, one of the best media centers around. With XBMC, not only can you enjoy your audio/videos/images that are stored in your local drive, you can also stream the multimedia content from the Web, via network share, SAMBA or even from uPnP devices. 2. 3. 4. 5. 6.

How Windows creates and stores password hashes and how those hashes are cracked. If you would like to read the next part in this article series please go to How I Cracked your Windows Password (Part 2). Introduction Passwords tend to be our main and sometimes only line of defense against intruders. The purpose of this article is to educate you on how Windows creates and stores password hashes, and how those hashes are cracked. How Windows Stores Passwords Windows-based computers utilize two methods for the hashing of user passwords, both having drastically different security implications. LM Password Hashes The LM hash of a password is computed using a six-step process: In practice, the password “PassWord123” would be converted as follows: Figure 1: A password transformed into an LM hash NTLM Password Hashes Conclusion
How I Cracked your Windows Password (Part 2) If you would like to read the first part in this article series please go to How I Cracked your Windows Password (Part 1). Introduction In the first part of this series we examined password hashes and the mechanisms Windows utilizes to create and store those values. We also touched upon the weaknesses of each method and possible avenues that can be used to crack those passwords. In the second and final article in this series I will actually walk you through the process of cracking passwords with different free tools and provide some tips for defending against having your password cracked. It is always crucial to note that the techniques shown here are strictly for educational purposes and should not be used against systems for which you do not have authorization for. Obtaining Password Hashes In order to crack passwords you must first obtain the hashes stored within the operating system. Physical Access If you are not quite comfortable doing this, you can use P.

Biometrics.gov - Introduction to Biometrics The NSTC Subcommittee on Biometrics and Identity Management developed this introductory material in order to better communicate both within the government and with other interested parties. Stating facts and discussing related issues in a consistent, understandable manner, will enable smoother integration of privacy-protective biometric solutions. Federal agencies are working to ensure that their outreach activities are consistent with, and occasionally reference, this suite of documents so that the public, press and Congress are able to easily understand their plans and discuss them productively. The Subcommittee encourages other entities to also use and reference this material. The background material here was developed in 2006. While the basic background information is still accurate, and useful for those new to the field, some of the more specific information on operational activities and specific standards are understandably dated.

Brute Forcing Passwords and Word List Resources Brute force, even though it's gotten so fast, is still a long way away from cracking long complex passwords. That's were word lists come in handy. It's usually the crackers first go-to solution, slam a word list against the hash, if that doesn't work, try rainbow tables (if they happen to have the tables for that specific hash type), and then the full on brute force. Some would say those first two steps are reversed, and it really is the choice of the the person doing it and the word lists they have to work with. Matt Weir and company created a cool tool that has the best of both worlds, Dictionary based Rainbow Tables with Dr-Crack, which you can find here: But, back to the reason of this post, word lists. I like to keep 3 size word lists: 1. small and fast: usually based on the output of one of the tools i'm about to tell you about 2. medium: this is my custom list that I add passwords I find / crack and generally think are good to add.
List of Rainbow Tables This page lists the rainbow tables we generated. LM rainbow tables speed up cracking of password hashes from Windows 2000 and Windows XP operating system. NTLM rainbow tables speed up cracking of password hashes from Windows Vista and Windows 7 operating system. The largest rainbow tables here are ntlm_mixalpha-numeric#1-9, md5_mixalpha-numeric#1-9 and sha1_mixalpha-numeric#1-9. Benchmark result of each rainbow table is shown in last column of the list below. Video demonstration of some rainbow tables on Perfect rainbow tables are rainbow tables without identical end points, produced by removing merged rainbow chains in normal rainbow tables. Rainbow Tables LM Rainbow Tables NTLM Rainbow Tables MD5 Rainbow Tables SHA1 Rainbow Tables Perfect Rainbow Table Generation, Sort, Merge and Conversion Commands All rainbow tables in this page can be generated with RainbowCrack software. © 2017 RainbowCrack Project
