According to the FTC alert, whatever the original purpose for the P2P transmission, and whatever its intended recipient,the material "is available on peer-to-peer (P2P) file-sharing networks to any users of those networks, who could use it to commit identity theft or fraud."
Time to tighten the clamps on business use of P2P connections -- if you allow them at all. If you don't, time to find out if any of your employees are using your networks for P2P, whether for business convenience or personal file-shares.
Any P2P use is risky, but improperly configured sharing could make an entire disk's contents available to the P2P network, not just the files being deliberately (if foolishly) shared over the connection.
It's all too easy for P2P's convenience to become an info-leak night mare, as Supreme Court Justice Breyer's office found out not long ago.
