A report classified as "top secret" said: "TAO successfully exploited a key mail server in the Mexican Presidencia domain within the Mexican Presidential network to gain first-ever access to President Felipe Calderon's public email account."

According to the NSA, this email domain was also used by cabinet members, and contained "diplomatic, economic and leadership communications which continue to provide insight into Mexico's political system and internal stability." The president's office, the NSA reported, was now "a lucrative source."
