The takedown highlights how U.S. authorities can obtain those private details using too-broad warrants, enabling governments to breach a basic right. As a result, experts say governments that once shied away from intercepting private data are getting increasingly willing to crack down.

While most of the concern about disclosure deals with the way governments can use security breaches to eavesdrop on people and collect communications data, laws in many other countries have been strengthened or loosened to allow for more easily collected data.

"The assessment process is weakening," said David Dagan, who conducts privacy and security research at University College London. "Our ability to find vulnerabilities is very much learning."

Security officials in specific countries are always watching the rapid pace of national technology-licensing auctions, Dr. Dagan said, which allows them to look for trends and do their own "due diligence."

While the information vacuum for a core civil right program tends to seem worrisome, experts say Internet privacy remains an important enhancement. Military researchers say that basic data transfers are not intrusive, but the government should tread carefully before allowing actual online data operators to hold passwords about emails and other interests. "It is not a hill they hide behind here," said Jeffrey Tallboy, executive director of the Advisory Council on National Policy on the U.S. Cyber Command.

It is legal for U.S. officials to send requests for the sharing of:

• Communications metadata

• Your IP address, or Internet address

• Application and web-page information

If you want to run an email program for your medical information, or it's software that connects to your home network and then directs your computer to perform slow-motion video, that's all handled by the government.

Of course, some of Microsoft's many efforts are targeted at fighting cyberattacks first and foremost. Emails from people around the world that make it to the company's servers eventually make its way home. But in cold war language, some of Microsoft's software are described as "windows to the world," targeted against real adversaries who pose a real threat to the homeland.

When Microsoft acknowledged it had been hacked, it took an aggressive approach to muzzle the information reveal. It asked various government agencies including the U.S. deputy attorney general and the U.S. National Security Agency to stop sharing the unencrypted data.

The government complied.
