Hosted by Darren Kitchen and Shannon Morse. New episodes Tuesdays.
Put together by a band of IT ninjas, security professionals and hardcore gamers, Hak5 isn't your typical tech show. We take on hacking in the old-school sense, covering everything from network security, open source and forensics, to DIY modding and the homebrew scene. Then we wrap it all up with a... Read More
The Hack Across America series concludes after 6 weeks and the first order of business at the new place in the San Francisco bay area is to build an inexpensive home server to host virtual machines. Then Shannon has a Windows power tools two-fer and Jason joins us for some Android application development -- can you way wardriving app?
Show Notes
First and foremost I apologize for the audio. I'm working on getting something resembling a set together and I'm still making due with my field equipment (read: shotgun mic). The 12' ceilings aren't helping. I promise to have it cleaned up by next episode when I get the rest of the Hak5 gear shipped out.
Speaking of next week, quick programming note: We'll be at E3 with Jenn Cutter. That means follow us on twitter for the latest.
Another reason to keep up on the social nets is for the upcoming SF Bay Hak5 meetup. Venue and other details TBD.
First appearing in MS-DOS 6, this command line program was a staple of Windows systems until being replaced by RD with the Windows NT line.

Do you ever feel paranoid of someone casually 'fixing' your computer with a handy flashdrive, thinking they are actually tossing on a keylogger? There is a useful tool called USB Write Protector for just that. It's a small windows utility that turns on or off USB write protection. USB Write Protector will secure you computer against would-be physical USB attacks like that of the USB Switchblade / USB Rubber Ducky by making USB thumb drives non-writable.
And second, have you ever run into the problem on Windows where you can't delete a file because it's being used by another program or person? Now we have Unlocker, a portable app that unlocks files so you can delete them.
USB Write Protector can be downloaded from here. By using USB Write Protector, you can protect your Windows computer from harmful rays from the USB Switchblade of death! Easily run the program from a .rar file, and just run the exe. You can also use this as a portable app. Double click, and choose USB Write Protection on or off. If you cant read Dutch, change this to English or whatever your language is. When ON, no files or data can be written onto a USB thumb drive.
Unlocker can be downloaded from here. Problems occur while attempting to delete a file such as: *Cannot delete file: Access is denied. *The file is in use by another program or user. *Make sure the disk is not full or write-protected and that the file is not currently in use, etc.
Trying to find the problem is a pain! So we have Unlocker. It's a free downloadable tool for Windows and it comes for installation or as a portable version. Just install and you're set. Now, try to delete a file and if you get a popup, right click on the file and choose Unlocker. Lockers will appear in a list. Choose unlock all and the file becomes available for use. If file is not locked, you still have the option to delete, rename, or move the file straight from unlocker.

The first order of business after moving to the SF Bay has been to build a cheap wall-mounted virtual machine server for the home.
Ok, I'll be honest I had a spare CPU and made the mistake of going to Fry's with a few bucks. But it's totally justifyable as I've needed a place to house a plethora of virtual machines for all sorts of mischevious testing.
Of course I cheaped out when it came to buying a case. Who needs a case? Wall mounted to a piece of black acrylic is so much cooler. Trust me, your spouce will love it.
This rig is running the latest version of Ubuntu and my favorite virtualization technology - VirtualBox.
What makes this project really special is the use of a Virtualbox web front end. There's a really nifty project over at code.google.com/p/vboxweb called VirtualBox Web Console -- and it does just that.
Simply using the VirtualBox API, Python, jQuery and flash (for the RDP client) it is able to provide a pretty slick web front-end to your virtual machines. Simply put, if you can get access to your home web server you can have access to all of your machines.
I'll be the first to admit that it's a little rough arond the edges, but I think this project holds a lot of promise. I'll continue using it and let you know how I really feel in the weeks to come.
What do you think? Found a better solution? Using VMware or another virtualization technology? Figure the wall-mounted server would be leeter with some laser beams? Email feedback@hak5.org.
