Eric Giguere writes "In a story that has Bay Street (the Canadian equivalent of Wall Street) in a kerfuffle, the Globe and Mail writes that bank employees defecting to set up a rival investment firm didn't realize that their employer could easily track the emails and messages they sent and received, even when they're sent via a nominally-secure system like RIM's BlackBerry. In particular, the employees were assuming that the messages they sent via direct PIN-to-PIN communication (a PIN uniquely identifies a BlackBerry device) weren't trackable. But if they're on the device, they're available to the employer to see. The employees may also have thought that PIN-to-PIN messages are encrypted, though RIM has always said that they're not -- it's only the connection to the corporate email server that is secure. A lot of damning information pulled from those emails and messages has made its way into a lawsuit."
