How to Hack Windows, Mac and Linux User Passwords

3238029478_aa1df44c98[1]
Password cracking  seems like a difficult task but these techniques make it as simple.  We’ll show you some software which cracks windows, mac, and linux user account passwords in a just a few minutes.   The programs basically do all the hard work for you as noted in this tutorial.

Breaking into a computer is an illegal activity but it does help to know how to re-access your own equipment.  So, this post is for informational and ethical purposes only! This how-to covers three OS we use and the methods to crack the log-in passwords.

Windows

For Windows OS, Ophcrack is the tool of choice. It is a free Windows Password cracker based on Rainbow Tables. It has a GUI which makes it easier to run. The software can decipher passwords up to 14 characters in length in a quick 10 seconds.

To use Ophcrack one needs to download the Ophcrack ISO and burn it to a CD (or load it via a USB drive). Run the CD by loading it in the tray and restarting the computer with the power switch. Switch to the BIOS options and set the computer to boot from the CD Drive. The computer boots up and reads the Ophcrack CD which then proceeds to break the password. Use this password to log into the machine.

Ophcrack is a multi-platform software and so can be used for Mac and Linux too.

Mac OS X

Apart from Ophcrack, another simple method involves using the Mac OS X installation CD (for v10.4). Insert and reboot to display UTILITIES. Choose RESET PASSWORD to get a new one. Login using this password. To reset the password in Mac OS X 10.5, reboot the computer and press COMMAND + S.

At the prompt type in:

sck -fy
mount -uw /
launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
dscl . -passwd /Users/UserName newpassword

Login with the new reset password.

Linux

Power on the computer, press the ESC key and on the boot loader (GRUB) screen select the ‘Recovery Mode’. Press the ‘B’ Key to enter the single user mode. At the default prompt, type in ‘passwd’ and key in your new password. For access to a single account on the system type ‘passwd username’ replacing ‘username’ with the login name for the account you would reset the password for.

A lesson in cracking is also a lesson in security. Joe Tech’s article advocates the use of encryption (Blowfish or AES-128) as a failsafe against password breach.

Google Wave Invites: How To Get Them

The web is buzzing with excitement and anticipation. In less than 24 hours, Google Wave will launch to 100,000 early adopters. The real-time communication platform has been making headlines ever since it was announced back in May as a result of its potentially game-changing features.

And while we’ve received our fair share of questions about Google’s newest product (most of which we answered in our Google Wave guide), one keeps popping up time and time again: how do I get an invite to Google Wave?


There Are Four Ways to Get an Invite


Google clarified things earlier today with an update to their blog. They specifically highlighted the four key ways you can secure an invite. Here are the methods and what you need to know:

1. You signed up early on for a Google Wave account. Google put up a request form for Wave invites not long after Wave was announced. Most of the invites arriving tomorrow will go to people on that list. Your chances improve if you signed up early on and wrote a message to the Wave team.

2. You have an account on the Developer Preview of Wave. The Sandbox version of Google Wave has been active for a select group of developers for several months now, allowing them to test Wave, report bugs, and build Wave extensions. They will all get accounts.

3. Some paying users of Google Apps will get accounts. It’s likely several companies asked Google for invites when the real-time tool launched. They will get accounts. Some schools that use Google Apps will also get early access.

4. You are invited by someone currently using Wave. This is the most intriguing revelation made today by the search giant. Here’s how Google explained it:

“We’ll ask some of these early users to nominate people they know also to receive early invitations — Google Wave is a lot more useful if your friends, family and colleagues have it too. This, of course, will just be the beginning. If all goes well we will soon be inviting many more to try out Google Wave.”

Do you know what this reminds us of? Gmail. Do you remember when it first came out and there were a select number of invites users could send out? I remember that people were willing to pay cold, hard cash for one of those invites. You might see the same type of frenzy over Wave.

Regardless, these are currently the only four ways to get an account on Wave. So if you don’t get an invite tomorrow, you still have hope. You’ll probably have to beg someone for an invite, though.

AT&T, Google trade barbs over Google Voice while FCC listens in

AT&T filed a scathing letter with the FCC earlier today complaining that Google's exhibiting a blatant double standard with Google Voice by blocking customers' access to numbers hosted by carriers that charge higher interconnect fees — something that's specifically forbidden for traditional telephone carriers under so-called common carrier laws. The argument essentially revolves around the fact that Google's move helps it compete unfairly against AT&T and others by arbitrarily blocking calls to numbers that'd cost it too much to connect, which AT&T says puts Google in an "intellectual contradiction" given its "noisome trumpeting" (ouch!) of support for net neutrality.

It is pretty interesting that Google wants a free, open internet with the left hand while it’s blocking certain telephone calls with the other, but Mountain View wasted no time in responding to the communication, posting an quick blog piece where it says there are “many significant differences” that should exempt it from common carrier legislation (some sound reasonable, though the argument that “Google Voice is currently invitation-only, serving a limited number of users” makes us think they’re digging pretty deep to come up with reasons they shouldn’t have to pony up the cash to get these calls connected).

If there's a bright side to the bickering, it's that both AT&T and Google can agree on one thing: rural carriers' continued ability to charge high connection fees hurts everyone — it's a "badly flawed" system, in Google's words, and it'd be great if the FCC would do something about it. Whether this whole spat ultimately influenced the outcome of the Google Voice iPhone app debacle is unclear, but it's obvious that AT&T's been stewing about this for a while — so let it all out, guys, mommy FCC's here for you, and one way or another we suspect GV's going to have to end up going legit if it wants to grow its user base by any significant measure. Check out the gallery for AT&T's letter and follow the read link for Google's shorter, slightly less aggressive response.

Create Your Own USB-Powered Gadgets [Weekend Project]

USB-powered desktop gadgets can be fun, and sometimes useful, but they’re often priced at not-so-fun prices. Learn how to splice a USB cable to power simple gadgets with MaximumPC’s guide.

The USB splicing tutorial is actually just one part of a single hack from their “Nine Kick-Ass DIY Projects,” but it’s a nice primer for anyone who’s never been up for cutting open their own spare cables. Once you’ve pinned down how to splice, connect, and ground your connections, you can power up just about any low-power device you have laying around, like fans, coffee warmers, toys, lights, or whatever else you’d like.”

You’ll definitely want to read through for MaximumPC’s cautions, and maybe Google the project you’re attempting to see if others warn against it, but this looks like a photo-friendly project waiting to happen. If you’ve already done it, in fact, we’d love to see the results in the comments.


Nocs is a Google Docs-Powered Notepad Clone [Downloads]

Windows only: Notepad clone Nocs looks and feels just like the regular Windows utility, but instead of editing local files, it can save and edit text notes directly to your Google Docs account.

Once you’ve downloaded, installed the utility, and entered your Google account information, you’ll be able to create text notes and save them directly to Google Docs. The notes can be encrypted by flipping a switch in the preferences, and you can switch from one account to another easily.

The only real problem is that the notes are stored on the Google Docs side in a single spreadsheet, and not in human-readable format—but if you are looking for a way to quickly store and retrieve notes that can be accessed from any computer (with Nocs installed), this might be worth a look. Nocs is free and open source, available for Windows only.

$4,000 Alienware Aurora ALX benchmarked: domination this world has never seen

Alienware’s Aurora ALX, which was just unveiled this week alongside ATI’s blisteringly fast Radeon HD 5870 GPU, gets going at $2,299. If that doesn’t bother you, the late-October estimated ship date might. Somehow, the benchmarking fiends over at HotHardware were able to grab hold of one of these rigs, and the results are fairly stunning (if not expected). Granted, their test configuration was a fully loaded $4,074 model, complete with a 3.33GHz Core i7 Extreme Edition 975 CPU, twin ATI Radeon HD 5870’s in a CrossFire configuration and 6GB of DDR3 memory. Oh, and blue lights. Lots of blue lights. Put simply, the one-two CPU / GPU punch produced results that led to domination that made pretty much anything else out there look weak. Don’t believe us? Hit that link for the bar-charted proof.

Video: Intel’s Light Peak running an HD display while transferring files… on a hackintosh

Intel just did a pretty impressive demo of its new Light Peak optical device interconnect, driving a greater-than-HD display while saturating an SSD RAID all over one cable, but we couldn’t help but notice the monster Frankenstein test rig on stage was running OS X — looks like someone’s violating their EULA! Video after the break.

Selectively Block Flash Animations in Google Chrome [Annoyances]

Firefox users have Flashblock and other extensions to cut down on memory-hogging, browser-destabilizing Flash animations thrown haphazardly around the web. If you’re a Google Chrome convert, BlockFlash2 can offer much the same protection against random moving objects.

At the How-To Geek’s home away from Lifehacker, Lifehacker intern alumnus Asian Angel details how to install, activate, and use the BlockFlash2 user script to replace Adobe Flash elements on a page with yellowed links. Those links can be clicked if the Flash element turns out to be important—like, say, on a YouTube page—or left to sit and never auto-play for faster, less crash-y browsing.

Got another Chrome-friendly script (besides the previously mentioned AdSweep) that streamlines the web? Tell us about it in the comments.
