Serious IT breach at the ABC. Bitcoins, as Crikey explained on Monday, is an online-only currency system quickly increasing in value. And one ABC staffer has apparently cashed in, in a serious IT breach Crikey understands is being investigated by the national broadcaster. An ABC insider takes up the intriguing story:

"The week before last an IT staff member of ABC Innovation with privileged access to ABC servers installed a 'Bitcoin miner' application on ABC servers. This application used idle CPU time of ABC servers and audience members to help create bitcoins for the private profit of this person. In other words, if you visited the ABC website, this program connected to your computer without your knowledge or permission and used it to help create money/currency for this individual for his own private profit. And that's putting to one side the whole shady nature of the currency itself.
