How to Set Up Google Chromecast : Windows 8

1.   Chromecast is a 2.83-inch (72 mm) HDMI dongle ,a digital media player developed by Google that plays audio/video content on a high-definition display by directly streaming it via Wi-Fi from the Internet or a local network. Users select the media to play using mobile apps and web apps that support the Google Cast technology. Alternatively, content can be mirrored from the Google Chrome web browser running on a personal computer, as well as from the screen of some Android devices.This post further brings you screen shots of the Chromecast setup as I set it up on one windows 8 Laptop...sadly it doesn't have a straight setup for UBUNTU OS...though I have seen few forums wherein a plugin mention in regular chrome browser would set the cast working...but alas not tried it is a simply setting it up on Windows 8.

Step 1 : As you plugin the chromecast powered by USB Power in the HDMI slot ,you get a similar looking screen.
On your Chrome browser log onto
As you click the above link you get a download setup file...around 800 that and your installation begins....
Typical Next Next.....
You get the device number as detected by the Laptop machine

Once connected a unique code is seen as below on the TV...just confirm that you see the same on your PC too as shown further below :
Unique code replicated on Laptop screen as below :
Click on That's My Code and continue as seen below :
Seen connecting to the network SSID
Setting up the Device on joining the network
and you are ready to cast :
The first time the device is ready to cast,expect recent update on the Chromecast dongle like seen below...likely to take few minutes...mine took 7-8 minutes
Updating still....12%
Updating still....61%
Updated and now applying updates
and the first look of the device on way to cast a Youtube stream as below :
What do I cast first ? course Rajinikanth....:-)

Few things to ponder and for info first time users :

- Why is not ready for Opensource OS?
- Works equally ready with Android devices with ease
- Does not work on a Windows OS running in Virtual Box/Machine.

Hardening your Android Device : Few Essentials

1.   Android is the most popular mobile platform in the world, with a wide variety of applications, including many applications that aid in communications security, censorship circumvention, and activist organization. Moreover, the core of the Android platform is Open Source, auditable, and modifiable by anyone. Unfortunately though, mobile devices in general and Android devices in particular have not been designed with privacy in mind. In fact, they've seemingly been designed with nearly the opposite goal: to make it easy for third parties, telecommunications companies, sophisticated state-sized adversaries, and even random hackers to extract all manner of personal information from the user. This includes the full content of personal communications with business partners and loved ones. Worse still, by default, the user is given very little in the way of control or even informed consent about what information is being collected and how.
2.  This presentation brings out few basic steps that every android phone user should configure to harden his/her device.Although the list is not completely exhaustive but it brings out basic necessities as expected from any smart user.

USB Condoms

1.   Ever heard of this term : USB CONDOM..first as I read about this though like some tech humour but it was was for real.This device prevents accidental data exchange when device is plugged into someone else’s computer or a public charging station. This is achieved by blocking the data pins on any USB cable and allowing only power to flow through. This minimizes opportunities to steal your data or install malware on your mobile device.

2.  As I read this ,the term became ok :-) to discuss around in my blog here.So the basic Juicejacking attack becomes null and void by the use of a USB Condom.

"The simple board at its core carries only the current from the outside pins on a USB connector — which pass along the 5V needed to charge. The middle pins that would normally transmit data can’t, as there’s no circuitry to do so on the Condom. You’ll be able to confidently charge in public as long as you’ve got your USB Condom handy, safe in the knowledge that no juice jacker is going to mess with your precious device." from :

FaceDancer : Security Issue Buzzing USB !!!!

1.   The typical USB protocol requires that anything with USB  declares itself as either a "device" or "host". "Host" can be a PC and other bigger machines accessible whereas "Devices" can be iPod, iPads, USB thumb drives, and other "small" accessory-like things.  If you ever want a USB "host" to pretend to be a USB "device", you need special hardware. The FaceDancer is that key.

2.   The FaceDancer allows a computer (or "host") to masquerade as a USB "device" to communicate with other USB devices or USB Hosts. The FaceDancer allows a developer to access data on the USB bus from high level languages like C, Python, and Ruby.
