Microsoft doesn't give NSA direct access to email



Microsoft does not give the National Security Agency direct access to its customers’ email or instant messages, contrary to previous news reports, a company executive said.
News reports last week suggested that Microsoft has helped the NSA circumvent the company’s own encryption in order to conduct surveillance on email accounts through Outlook.com, but company General Counsel Brad Smith said Tuesday that’s not true.
“We do not provide any government with direct access to emails or instant messages,” Smith wrote in a blog post. “Full stop.”
The company does not help government agencies circumvent its encryption, he added. “To be clear, we do not provide any government with the ability to break the encryption, nor do we provide the government with the encryption keys,” he wrote. “When we are legally obligated to comply with [government] demands, we pull the specified content from our servers where it sits in an unencrypted state, and then we provide it to the government agency.”
Microsoft on Tuesday asked U.S. Attorney General Eric Holder to permit Microsoft and other communications providers to share “more complete information” about how they handle national security requests for customer information, Smith added.
“We believe the U.S. Constitution guarantees our freedom to share more information with the public, yet the government is stopping us,” he said. The U.S. government has not responded to a June 19 request Microsoft made to publish the number of national security requests it receives, and the company hopes Holder will step in, Smith said.
Microsoft provides government access to data stored in its SkyDrive service and to Skype calls when presented with a legal order to do so, such as a search warrant or national security letter, Smith said. If asked for customer data in enterprise email or document storage, Microsoft attempts to redirect the requesting government agency back to the customer, he said, “and we notify the customer unless we are legally prohibited from doing so.”
Microsoft has never provided any government with customer data from any business or government customers for national security purposes, he said. In 2012, the company complied with four law enforcement requests related to business or government customers, he added.

NSA wiretaps Skype video calls

In 2008, Skype told that the service could not be wiretapped. Microsoft no longer stands by that claim, and a National Security Agency document shows analysts can eavesdrop on video calls.

Skype now has a backdoor that permits government surveillance of users' video and audio calls, according to a new report in the Guardian.
The report, based on leaked slides from the National Security Agency, appears to confirm growing suspicions about the popular video chat service -- and indicates calls may be able to be monitored as easily as an old-fashioned phone call.
One document quoted by the newspaper says intelligence analysts began to be able to monitor Skype video calls in July 2012: "The audio portions of these sessions have been processed correctly all along, but without the accompanying video. Now, analysts will have the complete 'picture.'"
This is a dramatic change from Skype's previous apparent resistance to eavesdropping.
In 2008, when the company was owned by eBay instead of Microsoft, a Skype spokeswoman told CNET that: "We have not received any subpoenas or court orders asking us to perform a live interception or wiretap of Skype-to-Skype communications. In any event, because of Skype's peer-to-peer architecture and encryption techniques, Skype would not be able to comply with such a request."
CNET asked Microsoft yesterday morning whether that statement was still correct. Microsoft did not respond.
It's possible for companies to create communications systems using strong end-to-end encryption believed to be proof against government snoops. Silent CircleOff-the-Record Messaging for instant messages, and e-mail messages encrypted with PGP do precisely that.
But few companies take that step, which can be a significant engineering expense and complicated for customers to use. Another classified document, citing collaboration between NSA and FBI, said: "Feedback indicated that a collected Skype call was very clear and the metadata looked complete. Collaborative teamwork was the key to the successful addition of another provider to the PRISM system."
After buying Skype, Microsoft dramatically overhauled its architecture, replacing peer-to-peer "super nodes" with thousands of servers run by Microsoft -- a more centralized approach that may have made it easier for government eavesdroppers. Around the same time, Microsoft would no longer stand by Skype's earlier claim to be wiretap-unfriendly.
Matthew Kaufman, Skype's principal architect, said in a message on an e-mail list last month that the server change was due to the increasing use of mobile apps, which interact with Skype differently than desktop machines and often run in the background or get evicted from memory:
 How do we solve that for our users? Servers. Lots of them, and more and more often in the Windows Azure cloud infrastructure. In the case of instant messaging, we have merged the Skype and Windows Messenger message delivery backend services, and this now gets you delivery of messages even when the recipient is offline, and other nice features like spam filtering and malicious URL removal. For calling, we have the dedicated supernodes already, and additional services to help calls succeed when the receiving client is asleep and needs a push notification to wake up. And over time you will see more and more services move to the Skype cloud, offloading memory and CPU requirements from the mobile devices everyone wants to enjoy to their fullest and with maximum battery life.
There is no evidence that encrypted Skype calls can be passively monitored by the NSA or FBI without the assistance of Microsoft. In other words, the intelligence agency's vast eavesdropping apparatus can't vacuum up and use Skype calls in the same way it reportedly can intercept unencrypted e-mail or Web traffic by using fiber taps.
Instead, the federal government would serve an order on Microsoft, using a Title III wiretap order or a Foreign Intelligence Surveillance Act order, requiring it to divulge the contents of a Skype call.
Microsoft's most recent transparency report says the company did not divulge any Skype audio or video content to police in 2012. But the report refers only to "law enforcement requests," and does not appear to include requests made under FISA's separate procedures.

Court Decides Warrantless Wiretapping Is OK

A US federal appeals court has given the green light for warrantless wiretapping. That means federal government can now spy on communications between America citizens without any warrants—and without fear of being sued, either.
The ruling came Tuesday, Wired reports, in the process reversing the original ruling from the first and only case to successfully challenge the Terrorist Surveillance Program. A three-judge panel of the 9th U.S. Circuit Court of Appeals wrote:
"This case effectively brings to an end the plaintiffs' ongoing attempts to hold the executive branch responsible for intercepting telephone conversations without judicial authorization."
The case centered around two American attorneys who struggled—but managed—to prove they were spied on without warrants. The court ruled that the pair could "bring a suit for damages against the United States for use of the collected information" but are unable to "bring suit against the government for collection of the information itself." Speaking to Wired, Jon Eisenberg, the lawyer working on behalf of the two attorneys, explained:
"This case was the only chance to litigate and hold anybody accountable for the warrantless wiretapping program. As illegal as it was, it evaded accountability."
All of which means that, from today, federal government can happily spy on anybody's communications without warrants or fear of the consequences.
