SkypeHide to Send secret messages into silence of Skype Calls

Polish Researchers have discovered a clever way to send secret messages during a phone call on Skype. We know that, by default skype calls use 256-bit advanced encryption, but researchers find that is not enough. So they find out this new way to communicate messages more secretly by using silence.

Mazurczyk, Maciej Karaś and Krzysztof Szczypiorski analysed Skype data traffic during calls and discovered that there is a way in Skype silence, where rather than sending no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.

So by taking advantage of this they hijacks these silence packets and then inject encrypted message data into some of them. The Skype receiver on other end will always simply ignores the secret-message data, but it can be decoded back to receive that secret message.

Team decide to present this at Steganography conference by creating a POC tool called SkypeHide that will be able to hijacks some of the silence packets and then injecting the encrypted hidden messages i.e text, audio or video , that can be transmitted at a rate of almost 1 kilobit per second.

We wish them Good Luck for their huge success and Conference Talk !

Facebook’s best hacks of 2012


Facebook’s best hacks of 2012

Facebook had some pretty sweet hacks over the past year. They basically deep-fried a server with phenomenal results. They created a QR code that can be seen from space. And one guy even made a 3D-printed map of Facebook.

The company holds regular internal hackathons to keep employees moving fast and breaking things, as per the social network’s now-famous Hacker Way code of conduct. And even outside those structured events, hacks just happen. It’s part of the Facebook way of life.

Some hacks are little more than pranks. Others end up becoming part of the site that you and I use every day. And in between those extremes, some hacks becoming canonized as Facebook lore, a sort of company-specific Jargon File that lives on Facebook’s servers and in its oral traditions.

This year, the company picked eight of its favorite hacks to share with the world. Here they are, in no particular order:
