Scientists have launched the satellite with the most secured crypto-channel in the world! It is quantum channel (BB84). But hackers had managed to sniff it. You should help those hackers to find out what was in the satellite’€™s transmission. File: https://mega.nz/#!jfpChKTT!TTDfy2l1hGrNwDrM3DQEjX6kmUVDy5DmMatnka5NvXc
