Kon-Boot is an prototype piece of software which allows to change contents of a linux kernel (and now Windows kernel also!!!) on the fly (while booting). In the current compilation state it allows to log into a linux system as ‘root’ user without typing the correct password or to elevate privileges from current user to root. For Windows systems it allows to enter any password protected profile without any knowledge of the password. It was acctually started as silly project of mine, which was born from my never-ending memory problems Secondly it was mainly created for Ubuntu, later i have made few add-ons to cover some other linux distributions. Finally, please consider this is my first linux project so far Entire Kon-Boot was written in pure x86 assembly, using old grandpa-geezer TASM 4.0.

So basically, Kon-Boot enables you to log into any Windows or Linux password protected computer without knowing the password or anything about it.

The tech behind it? Kon-Boot basically latches onto parts of the memory and starts patching parts of the kernel (the Brain!), mainly the parts that have to do with the log-on auth and security. These patches let you logon without a password. Then, the bootkit does it so quickly that it leaves no footprints behind after you leave.

DUDE!

To do this:
Go to the website above and download Kon-Boot, open the zip file, and burn the .iso to a disc. I use ImgBurner because it is fast, easy, and FREE.

Shut down the computer you intend to get on to. When booting up, if it isn’t already set to boot from CD (or flashdrive, or whatever Kon-Boot is on), go into the BIOS and set it. You should see the Kon-Boot splash screen for a few seconds, then the username/password screen will appear with the main username already set if they have it saved. If not you need to know the username ahead of time. Press enter or type in some random characters (it doesn’t really matter) and press enter. You’re in!

Now party, snoop around, and get that file you wanted. Get your flashdrive or CD out, then shut the computer back off like usual.

Protecting yourself:
Password protect your BIOS!
True Crypt your entire harddrive!

Want to bypass those nasty restrictions imposed by your corporate or university firewalls? Darren has just the trick with Internet Redirection. Ever wanted to hide secret data inside a photo? Shannon’s show us a neat steganography app. Plus Matt answers your virtualization questions!

Internet Redirection

Corporate and university firewalls can be a particular PITA — especially if you’re a gamer. And while SSH tunneling (even over DNS)or VPN technologies are often preferred, it is quite possible to “bounce” your traffic off an Internet Redirection server. Like a fancy proxy, rinetd allows you to specify incoming and outgoing IP and port. It features basic client access rules based on IP and even supports logging. In my segment I demonstrate accepting traffic on port 80 and transmitting it to an IRC server on port 6667.

Granted this isn’t going to fool your more complex firewalls that actually inspect packets — but if you’re just looking to get traffic through an open port I highly recommend giving rinetd a try.

–Darren

Steghide

Download a copy of Steghide. Extract the zip.

You want to hide a file. First thing you need is a file to hide it in. Choose a file – whether that be a music file, jpeg, word document… whatever – and save it inside the steghide folder, which was extracted from the zip folder. Also, save your file that you want to hide inside that same folder as well.
Open up your command prompt and open the steghide folder directory. Open the steghide.exe file. The last few rows of type will tell you how to embed and extract your hidden file.

Embedding:
Type into the command prompt: ’steghide embed -cf file.jpg (this is your regular file) -ef hiddenfile.txt’ (this is the file you want to hide).
Choose a Passphrase and you’re done! You’ll notice the original photo or music file has changed it’s byte size now that you’ve embedded something inside it.

Extracting:
Type into the command prompt: ’steghide extract -sf file.jpg’ and enter the passphrase. Now, you’ll see the extracted hidden file appear inside the same folder.
Your done! Simple, eh?

Darren shows off some nifty tricks for Netcat and a targeted brute force attack dictionary generator. Matt continues his series on Virtualization with redundancy and Shannon pimps the blog with her WordPress plugin picks. Plus the results of our Monkey Contest, the Code Challenge and this weeks easter egg hunt

Show Notes

Common User Password Profiler

The Common User Password Profiler from Remote-Exploit is a password/passphrase generator specifically targeted as an individual user. Feed it some info like names, birth dates, spouce, children and pets and it will generate individually, or along with an existing dictionary, thousands of potential passwords. Just add water, feed to your favorite brute forcer and enjoy.

From personal experience I can vouch that, while simple sounding, this would have a HIGH success rate on some of my _former_ (L)users. Administrators take note and enforce BOFH password requirements

netcat – “The Swiss-army knife for TCP/IP”

When it comes to sending and receiving TCP and UDP any which way from the console nothing is more versatile or easy to use than netcat.

With a few simple commands you can use netcat to initiate chat, file transfer or even shell access in either direction between a “server” and a “client”.

The tool can be set to listen or broadcast on any port and tied together with some shell-fu almost anything is possible.

Some listener favorites include cloning hard drives over a network with dd and netcat, tailing a log across the network, port scanning, IP redirecting, or even spoofing user-agents and referrers. Internet Explorer 22 anyone?

Digininja points to this great netcat cheat sheet (PDF 128K).

Shannon’s WordPress Plugin Picks

Twitme

This plugin allows you to automatically post your new posts on the twitter website. This is good because the iPod and iPhone for example have a large amount of twitter clients to pick from. Your blog posts will arrive to people while they are walking the streets.

Socialite

Socialite allows your WordPress posts to publish to Twitter, Facebook, and MySpace. Each social networking site can be enabled or disabled for publishing, and each is configured separately with their own options. Support for Short URL services such as zz.gd and Tinyurl.com is also supported.

Sociable

Automatically add links to your favorite social bookmarking sites on your posts, pages and in your RSS feed. You can choose from 99 different social bookmarking sites!

MobilePress

MobilePress is a WordPress plugin that will render your WordPress blog on mobile handsets, with the ability to use customized themes. The plugin also allows specific themes for specific devices / mobile browsers, such as iPhone, Opera Mini, Windows CE Mobile and other generic handset browsers.

Resize at Upload Plus

The plugin will automatically resize an image upon upload, depending on the maximum width and height that you define. Gone are the days when you, or your client, will ruin a site’s layout by uploading a huge file with 25 megapixels. Be advised: there is no backup, no copy of the originally uploaded image.

WP-Cache 2.0

WP-Cache is an extremely efficient WordPress page caching system to make your site much faster and responsive. It works by caching Worpress pages and storing them in a static file for serving future requests directly from the file rather than loading and compiling the whole PHP code and then building the page from the database. WP-Cache allows to serve hundred of times more pages per second, and to reduce the response time from several tenths of seconds to less than a millisecond.

WordPress Backup

Backup the upload directory (images), current theme directory, and plugins directory to a zip file. Zip files optionally sent to email.

WP Security Scan

Scans your WordPress installation for security vulnerabilities and suggests corrective actions.

WP Ban

It will display a custom ban message when the banned IP, IP range, host name or referer url trys to visit you blog. You can also exclude certain IPs from being banned. There will be statistics recordered on how many times they attemp to visit your blog. It allows wildcard matching too.

pixelstats

Count every viewer and every article view for each blog entry, no matter how and where it is read: pixelstats tracks views of each blog post or page, not only on a single article page but also on each other page where the complete article is shown, i.e. the blog front page, category pages, search result page, archive pages and even RSS fee

Thanks for watching, subscribing, and most of all supporting the show. Custom commissioned WiFi Pineapples running Jasager are still available.

Twilight Hack

Wii Homebrew

You need a few things:

* wii
* wii mote controller
* computer
* internet access
* small sd card formatted as FAT.
* Zelda Twilight Princess for Wii

The Wii Brew Wiki
Homebrew Channel

How to install the Wii Homebrew Channel on your Wii using the Twilight Hack.

Download the Twilight Hack. There are two versions, one for Wii system 3.3, and one for 3.4. I haven’t updated mine, so I’m still on 3.3.

Download the Homebrew Channel zip file.

Also, if you want, go ahead and download some apps from the HackMii website. I suggest the Homebrew Browser so you dont have to copy apps to the SD card every time you wanna download something new.

You’ll need a small SD card 2 gig or smaller. Make sure to format your SD card as FAT. Do to this, right click on the SD card, and choose format. Simple!

Put the SD card in your Wii, then turn it on. Go to the Wii Options–>Data management–>Save Data–>Wii section of the menu. Find your Zelda: Twilight Princess saved file, and copy it. If you havent played it yet, you might not have a saved file, so go ahead and play a bit. Put your SD card in your computer and copy the “Private” folder from the card to your comp, just in case you may need it in the future.

Move the homebrew executable that you extract from the zip file to your SD card root directory and save it as boot.dol or boot.elf.

Also, save the Twilight Hack Private folder from the extracted zip file to your SD card.

Now, check out your Twilight Princess game CD. It should have some hard to read serial numbers inscribed on the inner circle. Match this serial with the corresponding “Save slot”.
RVL-RZDE-0A-0 JPN /private/wii/title/rzde/data.bin TwilightHack0RVL-RZDE-0A-0 USA /private/wii/title/rzde/data.bin TwilightHack0RVL-RZDE-0A-2 USA /private/wii/title/rzde/data.bin TwilightHack2
Region Inner circle text File Save slot
Europe/Australia RVL-RZDP-0A-0 JPN /private/wii/title/rzdp/data.bin Twilight Hack
Asia (JPN) RVL-RZDJ-0A-0 JPN /private/wii/title/rzdj/data.bin Twilight Hack
America (USA)
America (USA)
America (USA)

Inside the private–>wii–>title folder are 3 folders with letters corresponding to the serials. Delete the two that don’t match your cd.

Put your SD card back in the Wii. Go to Wii Options–>Data management–>Save Data–>Wii and erase the Zelda save now. Open the SD card menu and choose Twilight Hack. Copy to the Wii.

Stick your game CD in your Wii and boot up Zelda! Choose the save slot that corresponds with your serial. Mine was TwilightHack0. Go ahead and skip the intro, it doesn’t hurt the hack. Once you see Link as a playable character, either walk backwards or talk to the guy in front of you. This will start up the hack install process, so just choose “Agree” to everything.

You’re done! Now you can play on the homebrew channel. Yay!

Get the homebrew browser so you can download apps straight from the channel instead of shuffling your SD card around.

To do that, simply stick the sd in your computer and create a folder called apps. Copy the homebrew browser folder and its contents over to the sd and back it goes to your wii!

If you have some cool homebrew for the Wii, tell me about it or ask me any questions at Snubs@hak5.org.

Don’t forget to submit your questions@hak5.org and feedback@hak5.org and thanks for your contributions.

DNS Tunneling

The basic premise comes down to this: If you can connect to a wireless access point that has a captive portal running, constantly forwarding your web requests to a payment page, you can most likely bypass those restrictions if you can get name resolution.

Simply open a shell and ping your favorite website. It doesn’t matter if you get ICMP packets back, what you’re looking for is name resolution. If ping says “Pinging www.l.google.com [74.125.95.99]” or similar you should be all set to tunnel your traffic over DNS

In order to get going you’ll need a domain, or sub-domain, a set of Perl scripts called Ozyman, a server to run the ozyman and ssh daemons on, and a little luck

Full step by step instructions can be found at Mubix’s wonderful blog o goodness at Room362.com.

Public Key Encryption

In this segment we show you how to setup public key authentication between a windows and a linux host. There are many different software packages through which to accomplish this but we used openssh and putty.

Requirements:

Linux machine or VM running OpenSSH (most distros have it in their repository, or you can find it here: http://www.openssh.com/portable.html

Windows machine with putty software (download the whole package) http://www.openssh.com/portable.html

Installing openssh on linux is relatively straightforward. Refer to their site for details. Once that’s setup, we generated a key using the command “ssh-keygen” and specified the filenames. You can customize the keys you generate as you wish, but we went with the defaults. After entering a passphrase twice, you’ll have a public and private key file, with the public having the extension .pub. The private key file stays on the server but we copy the public key over to our windows machine and convert it into putty format using Putty Generator. After you have the key, you can either pass it with scp using scp -i (pscp in our example since we’re using putty’s scp executable), or you can use the putty ssh client in order to pass the key instead of just a password to authenticate to the server. This makes an easy two-factor authentication mechanism.

Driver Backup

After installing a fresh copy of your Windows OS of choice, the biggest headache for most of us is the arduous task of trying to locate drivers for all of our different components. So this post is all about making your reinstall a little less troublesome.

Hereís a list of some of the better driver backup utilities!

DriverBackup2 is a lightweight driver-backup tool. The application is portable with a caveat: youíll need administrative privileges for full use. You can opt to backup one or all of your drivers, the backed up files are dumped into a tree structure based on driver name. DriverBackup2 also allows you to restore and delete unnecessary drivers. If you ever hunted for obscure drivers online, when installing legacy or obscure hardware for instance, DriverBackup2 will save you the hassle of searching them out again.

Double Driver lists all the hardware drivers installed on your system and creates backups of both the actual drivers and lists of the driver names. While handy with any computer, Double Driver really shines if you have a computer that came with pre-installed drivers that are hard if not impossible to come by. With a few clicks youíll have those archaic laptop drivers backed up and ready to put back to work after a fresh install.

DriverMax allows you to easily reinstall all your Windows drivers. No more searching for rare drivers on discs or on the web or inserting one installation CD after the other. Simply export all your drivers (or just the ones that work ok) to a folder or a compressed file. After reinstalling Windows all drivers can be back in place in less than 5 minutes.

DriverView is a helpful upgrade from looking through devices individually in the Device Manager, but the real value here is in the list generation. Create an HTML-formatted backup list for your future troubleshooting needs or export to text to show friends or forum members just whatís gone wrong. While it doesnít actually backup drivers, if youíre still into doing things the old fashion way, DriverView is a great choice!

Now that weíve got all of the corporate slogans and descriptions out of the way, my personal favorite is the first link weíve talked about here. The interface is the least cluttered, and the process really couldnít be any easier. For those of you who are looking to deploy driver backups in an automated fashion, thereís a built in commandline builder! Like I said, Iíve personally used it and really does make life alot easier after a reinstall.

So check it out and if you have any questions, remember: matt@hak5.org – Revision3 Forum or Hak5 Forum

Music Organizers

I have thousands of songs on my computer and some of them are missing titles, artists, etc. So when I hop on iTunes to download my feed of podcasts (like Hak5!), I use TuneUp Media to clean up some of my music.

TuneUpMedia

TuneUp Media has the ability to find your songs basically by listening to them, and tell you the information for each one. You simply drag your song over to the clean up bar on the right, and TuneUp finds your songs info in a few seconds. It even gives you a choice of album art you can use.

I like TuneUp simply because Iím really organizational. There are a few bugs thoughÖ Firstly, once you download TuneUp, you donít have the option to close it while in iTunes (unless this has changed recently). Second, there are two versions – free and not free. With the free version, you only have 500 songs to clean up. In the payed version- you can clean up as much as you want.

TagScanner

The second one is TagScanner. Tagscanner is good for someone who doesnít like iTunes. In tagscanner, you can not only clean up the names and artists on your music, but you can also fix up the ID3 tags for each song, down to lyrics and album art. You can also export your music into a .txt or excel spreadsheet, which is pretty neat.

Then in part three he covers basic Wireshark usage and advanced techniques. Read more on packet sniffing on his blog at ChrisGerling.com

Shannon Morse shares with us DosBox, the free and open source IBM PC emulator that allows you to break out those old floppies and play your DOS games once again. While we wait for DNF, anyone for a Duke Nukem 3D deathmatch?

Christine Bourquin demos Alice, an innovative 3D programming language that makes it easy to teach programming using a simple drag-and-drop interface. Perfect for the next generation of computer scientists.

Darren Kitchen brings us his review of Day-Con with photos courtesy of the security twits. He also talks about Jasager batteries both big and small.

And on a production note: We’ve switched over from a standard-def composite based video mixing solution to a high-def HDMI based system. We’re not ready to release the full 720p quite yet as we’re ironing out (read: developing on the fly) the post production process but in the mean time we’ve got damn good looking 480p and we’re looking for your feedback. Thanks a million to everyone who has donated and helped make this happen!

On my segment, I chatted with ya’ll about Dosbox. The first time we shot the segment, we had such bad audio quality that I had to go back and shoot the segment again late into the night… /sigh. Such things happen when you work on a show.

Dosbox is a totally nifty creation that emulates an IBM pc compatible computer running MSDOS. Although dosbox is basically intended to run old school video games from the late 80′s and early 90′s, it can take on other tasks.

One of the key features about Dosbox is it’s ability to run peer-to-peer and internet/intranet video games. It simulates an entire modem, so you and your friends can play those old TCP/IP or IPX network multiplayer games easily with each other.

You can also take simple photos of your gameplay or video footage which is created with the ease of the click of a button. Hit CTRL+F5 for your photo, or CTRL+ALT+F5 to begin a video then again to end it. This makes for easy tutorial building, as well as nice video clips to share. The video is recorded into a folder called captures.

I found lots of good information about Dosbox at this wiki: http://en.wikipedia.org/wiki/DOSBox, as well as their main site: http://www.dosbox.com/. Here, you can find a HUGE list of games that are supported by Dosbox as well as FAQ’s, their own wiki, and forums.

Oh, and did I mention it’s open source and free? Yup

Synergy co-op Mode gives us an amazingly fun mod called Synergy.  You can use this mod for Half-Life 2, ep. 1, and ep. 2. To install it, you basically have to have the Half-Life games, with the SDK Source installed.  You then run the synergy installation and it’s all set!  Synergy mod even shows up as an independent game in X-fire.  It’s pretty cool

There’s a few kinks I found while playing the game with 2 other people.  There are a few places where the game skips (just a few puzzles, the end of a level, etc..). Another thing is the Half-Life games were obviously made for one player mode, and when you have multiplayer- it gets a little easy.

But it’s frackin TOTALLY RAD to run into a level with a team and take it out in minutes~!! omg!  Play it!!  It’s really fun to go through the Half-Life games on multiplayer!!!
