Hiding Secret Messages In Skype Silences

Orome1 writes "A group of researchers from the Institute of Telecommunications of the Warsaw University of Technology have devised a way to send and receive messages hidden in the data packets used to represent silences during a Skype call. After learning that Skype transmits voice data in 130-byte packets and the silences in 70-byte packets, the researchers came upon the idea of using the latter to conceal the sending and receiving of additional messages."

There goes that idea

If you are going to hide something, don't let everyone know where you put it.

Now that the exploit has been discussed it will be watched out for.

Nothing to see hear.

Re:Eloquent silence

Exactly what I was thinking.

You would think that a packet specifying X seconds of simulated silence could be packed into a few bits, so maybe two bytes should suffice.

Were you planning on sending that "two seconds of silence" packet at the _start_ of the pause? If so I know a few theoretical physicists and at least one state lottery commission who would _love_ to see your algorithm.

C may currently have overtaken Java as the most popular language but Whitespace is going to overtake them all!
