300px-National_Security_Agency_svg_1The first time we heard about the secret NSA projects and the PRISM program was when Edward Snowden leaked NSA documents showing how Verizon was ordered to hand over phone records. Then we heard about larger tech involvement with the US Government, listing Microsoft, Yahoo, Google, AOL, Apple, Facebook, PalTalk, Skype, and YouTube. Edward Snowden even did a Q&A on Twitter with #AskSnowden.

Today, The Guardian has reported that Microsoft has allowed the NSA to bypass encryption to view users’ emails on Outlook.com, video and chat conversations through Skype, and even their files on SkyDrive. The details came to surface in more top-secret documents provided by Edward Snowden.

The documents list:

• Microsoft helped the NSA to circumvent its encryption to address concerns that the agency would be unable to intercept web chats on the new Outlook.com portal;

• The agency already had pre-encryption stage access to email on Outlook.com, including Hotmail;

• The company worked with the FBI this year to allow the NSA easier access via Prism to its cloud storage service SkyDrive, which now has more than 250 million users worldwide;

• Microsoft also worked with the FBI’s Data Intercept Unit to “understand” potential issues with a feature in Outlook.com that allows users to create email aliases;

• Skype, which was bought by Microsoft in October 2011, worked with intelligence agencies last year to allow Prism to collect video of conversations as well as audio;

• Material collected through Prism is routinely shared with the FBI and CIA, with one NSA document describing the program as a “team sport”.

The latest documents come from the NSA’s Special Source Operations (SSO) division, described by Snowden as the “crown jewel” of the agency. It is responsible for all programs aimed at US communications systems through corporate partnerships such as Prism.

Microsoft made the following statement to The Guardian:

We have clear principles which guide the response across our entire company to government demands for customer information for both law enforcement and national security issues. First, we take our commitments to our customers and to compliance with applicable law very seriously, so we provide customer data only in response to legal processes.

Second, our compliance team examines all demands very closely, and we reject them if we believe they aren’t valid. Third, we only ever comply with orders about specific accounts or identifiers, and we would not respond to the kind of blanket orders discussed in the press over the past few weeks, as the volumes documented in our most recent disclosure clearly illustrate.

Finally when we upgrade or update products legal obligations may in some circumstances require that we maintain the ability to provide information in response to a law enforcement or national security request. There are aspects of this debate that we wish we were able to discuss more freely. That’s why we’ve argued for additional transparency that would help everyone understand and debate these important issues.

In a joint statement, Shawn Turner, spokesman for the director of National Intelligence, and Judith Emmel, spokeswoman for the NSA, said:

The articles describe court-ordered surveillance – and a US company’s efforts to comply with these legally mandated requirements. The US operates its programs under a strict oversight regime, with careful monitoring by the courts, Congress and the Director of National Intelligence. Not all countries have equivalent oversight requirements to protect civil liberties and privacy.

In practice, US companies put energy, focus and commitment into consistently protecting the privacy of their customers around the world, while meeting their obligations under the laws of the US and other countries in which they operate.
