`  == New Fake ``CryptoLocker`` circulating on the Internet ==  A few days ago, in the institution where my wife works they catch it with CryptoLocker-like virus that in all external signs resembles normal CryptoLocker virus. I asked her to send me several ``encrypted`` files together with their unencrypted copies to analyze them and the first thing I noticed was the difference in their size. The ``encrypted`` files are smaller than the originals - something that will not happen when encoding with RSA, especially ``2048-RSA`` as in the message for ransom claimed. This ``CryptoLocker`` simply use some sort of data compression like in RAR format.   Does anyone have more information about this virus?   `
