British officials, speaking on condition of anonymity, said they were aware of the hacking, but that it did not pose a risk to national security. Passwords for their communications within Whitehall would be different from any of those used to access the Stratfor sites. Whitehall communications would also be protected by extra security walls, officials said.

However, they added that their personal communications could be at risk if individuals used the same password as they used to access Stratfor for their bank accounts and other personal communications.
