Slightly off topic, but a few years back there was a group that gained access to PRNewswire’s servers and was able to read announcements of earnings, mergers, etc earlier than the public. PRNewswire had a scheduled announcement function that allowed precomposed announcements to be made public at a specified future time. The group used this information to make stock and option trades and was pursued by the government for both the hacking and insider trading. Today, the obvious target for this type of attack would be xoom.
