Responsibility Deflected, the CLOUD Act Passes

Cloud leaky 0

UPDATE, March 23, 2018: President Donald Trump signed the $1.3 trillion government spending bill—which includes the CLOUD Act—into law Friday morning.

“People deserve the right to a better process.”

Those are the words of Jim McGovern, representative for Massachusetts and member of the House of Representatives Committee on Rules, when, after 8:00 PM EST on Wednesday, he and his colleagues were handed a 2,232-page bill to review and approve for a floor vote by the...

We Still Need More HTTPS: Government Middleboxes Caught Injecting Spyware, Ads, and Cryptocurrency Miners

Sovereign keys

Last week, researchers at Citizen Lab discovered that Sandvine's PacketLogic devices were being used to hijack users' unencrypted internet connections, making yet another case for encrypting the web with HTTPS. In Turkey and Syria, users who were trying to download legitimate applications were instead served malicious software intending to spy on them. In Egypt, these devices injected money-making content into users' web traffic, including advertisements and cryptocurrency mining...

Geek Squad's Relationship with FBI Is Cozier Than We Thought

Geek 1 1

Update: A Best Buy spokesperson confirmed to reporters that at least four Geek Squad employees received payments from the FBI.

After the prosecution of a California doctor revealed the FBI’s ties to a Best Buy Geek Squad computer repair facility in Kentucky, new documents released to EFF show that the relationship goes back years. The records also confirm that the FBI has paid Geek Squad employees as informants.

EFF filed a Freedom of Information Act (FOIA) lawsuit...

How Congress’s Extension of Section 702 May Expand the NSA’s Warrantless Surveillance Authority

Nsa eagle 2

Last month, Congress reauthorized Section 702, the controversial law the NSA uses to conduct some of its most invasive electronic surveillance. With Section 702 set to expire, Congress had a golden opportunity to fix the worst flaws in the NSA’s surveillance programs and protect Americans’ Fourth Amendment rights to privacy. Instead, it reupped Section 702 for six more years.

But the bill passed by Congress and signed by the president, labeled S. 139, didn’t just extend Section...

When Trading Track Records Means Less Privacy

Locational privacy

Sharing your personal fitness goals—lowered heart rates, accurate calorie counts, jogging times, and GPS paths—sounds like a fun, competitive feature offered by today’s digital fitness trackers, but a recent report from The Washington Post highlights how this same feature might end up revealing not just where you are, where you’ve been, and how often you’ve traveled there, but sensitive national security information.

According to The Washington Post report, the fitness tracking...

An Open Letter to Our Community On Congress’s Vote to Extend NSA Spying From EFF Executive Director Cindy Cohn

Paglen nsa credit 1

Dear friends,

Today, the United States Congress struck a significant blow against the basic human right to read, write, learn, and associate free of government’s prying eyes. 

Goaded by those who let fear override democratic principles, some members of Congress shuttered public debate in order to pass a bill that extends the National Security Agency’s unconstitutional Internet surveillance for six years. 

This means six more years of warrantless surveillance under...

Groups Line Up For Meaningful NSA Surveillance Reform

702 og

Multiple nonprofit organizations and policy think tanks, and one company have recently joined ranks to limit broad NSA surveillance. Though our groups work for many causes— freedom of the press, shared software development, universal access to knowledge, equal justice for all—our voices are responding to the same threat: the possible expansion of Section 702 of the FISA Amendments Act.

On January 5, the Rules Committee for the House of Representatives introduced S. 139. The...

Supreme Court Won’t Hear Key Surveillance Case

702 og 1

The Supreme Court announced today that it will not review a lower court’s ruling in United States v. Mohamud, which upheld warrantless surveillance of an American citizen under Section 702 of the Foreign Intelligence Surveillance Act. EFF had urged the Court to take up Mohamud because this surveillance violates core Fourth Amendment protections. The Supreme Court’s refusal to get involved here is disappointing.

Using Section 702, the government warrantlessly collects...

Court Challenges to NSA Surveillance: 2017 in Review

Nsa eagle 2

One of the government’s most powerful surveillance tools is scheduled to sunset in less than three weeks, and, for months, EFF has fought multiple legislative attempts to either extend or expand the NSA’s spying powers—warning the public, Representatives, and Senators about circling bills that threaten Americans’ privacy. But the frenetic, deadline-pressure environment on Capitol Hill betrays the slow, years-long progress that EFF has made elsewhere: the courts.

2017 was a year...

Urgent: We Only Have Hours Left to Stop the NSA Expansion Bill

According to reports published Tuesday evening by Politico, a group of surveillance hawks  in the House of Representatives is trying to ram through a bill that would extend mass surveillance by the National Security Agency. We expect a vote to happen on the House floor as early as tomorrow, which means there are only a few hours to rally opposition.  

The backers of this bill are attempting to rush a vote on a bill that we’ve criticized for failing to secure Americans’ privacy. If...

Don’t Reauthorize NSA Spying in a Must-Pass Funding Bill

Nsa eagle 2

The next two weeks will be a flurry of activity in Congress. Before they can leave for the holidays, our government must—at minimum—pass at least one bill to keep the government running and also decide what to do about a controversial NSA spying authority called Section 702. Some legislators want to reauthorize Section 702, without meaningful reform, by attaching it to must-pass spending legislation. This is a terrible idea. The legislative process surrounding Section 702 already lacks...

FISC Assurances on Spying Leave Too Many Questions Unanswered

Nsa eagle 2

Last week, FBI Director Christopher Wray faced questions from the House Judiciary Committee about how his department is implementing one of the government’s most powerful surveillance tools. Despite repeated bipartisan requests, Director Wray refused to tell the Members of the Committee how many Americans have been impacted by Section 702, enacted as part of the FISA Amendments Act. This isn’t the first time the FBI has refused to answer to Congress.

EFF has long held that Section...

EFF’s Street-Level Surveillance Project Dissects Police Technology

Sls header plain

Step onto any city street and you may find yourself subject to numerous forms of police surveillance—many imperceptible to the human eye.

A cruiser equipped with automated license plate readers (also known as ALPRs) may have just logged where you parked your car. A cell-site simulator may be capturing your cell-phone data incidentally while detectives track a suspect nearby. That speck in the sky may be a drone capturing video of your commute. Police might use face recognition...

Printer Tracking Dots Back in the News

Printer dots 1

Several journalists and experts have recently focused on the fact that a scanned document published by The Intercept contained tiny yellow dots produced by a Xerox DocuColor printer. Those dots allow the document's origin and date of printing to be ascertained, which could have played a role in the arrest of Reality Leigh Winner, accused of leaking the document. EFF has previously researched this tracking technology at some length; our work on it has helped bring it to public...
