Is There a Spanish Idiom for "Hand Caught in the Cookie Jar?"

Another harmful and embarrassing revelation for the NSA:

The NSA has been systematically eavesdropping on the Mexican government for years. It hacked into the president’s public email account and gained deep insight into policymaking and the political system. The news is likely to hurt ties between the US and Mexico.

The National Security Agency (NSA) has a division for particularly difficult missions. Called “Tailored Access Operations” (TAO), this department devises special methods for special targets.

That category includes surveillance of neighboring Mexico, and in May 2010, the division reported its mission accomplished. 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.”

Everybody spies on everyone they can manage to spy on, especially neighbors. The trick is to be smart enough about it not to get caught, and if you do get caught you want to get caught quietly. If Mexico had caught us, there would be words behind closed doors, maybe an expulsion or two. To get caught out in public like this? That hurts.
