How to Fight Mass Surveillance Even Though Congress Just Reauthorized It
What the battle looks like after Section 702's reauthorization
For over a decade, civil libertarians have been fighting government mass surveillance of innocent Americans over the Internet. We’ve just lost an important battle. On Jan. 18, when President Trump signed the renewal of Section 702, domestic mass surveillance became effectively a permanent part of U.S. law.
Section 702 was initially passed in 2008, as an amendment to the Foreign Intelligence Surveillance Act of 1978. As the title of that law says, it was billed as a way for the National Security Agency to spy on non-Americans located outside the United States. It was supposed to be an efficiency and cost-saving measure: The NSA was already permitted to tap communications cables located outside the country, and it was already permitted to tap communications cables from one foreign country to another that passed through the United States. Section 702 allowed it to tap those cables from inside the United States, where it was easier. It also allowed the NSA to request surveillance data directly from Internet companies under a program called PRISM…
How the Supreme Court Could Keep Police From Using Your Cellphone to Spy on You
The cellphones we carry with us constantly are the most perfect surveillance device ever invented, and our laws haven’t caught up to that reality. That might change soon.
This week, the Supreme Court will hear a case with profound implications for your security and privacy in the coming years. The Fourth Amendment’s prohibition of unlawful search and seizure is a vital right that protects us all from police overreach, and the way the courts interpret it is increasingly nonsensical in our computerized and networked world. The Supreme Court can either update current law to reflect the world, or it can further solidify an unnecessary and dangerous police power…

Mister Chairman and Members of the Committee, thank you for the opportunity to testify today concerning the security of credit data. My name is Bruce Schneier, and I am a security technologist. For over 30 years I have studied the technologies of security and privacy. I have authored 13 books on these subjects, including …
Who Is Publishing NSA and CIA Secrets, and Why?
There’s something going on inside the intelligence communities in at least two countries, and we have no idea what it is.
Consider these three data points. One: someone, probably a country’s intelligence organization, is dumping massive amounts of cyberattack tools belonging to the NSA onto the Internet. Two: someone else, or maybe the same someone, is doing the same thing to the CIA.
Three: in March, NSA Deputy Director Richard Ledgett described how the NSA penetrated the computer networks of a Russian intelligence agency and was able to monitor them as they attacked the U.S. State Department in 2014. Even more explicitly, a U.S. ally—my guess is the U.K.—was not only hacking the Russian intelligence agency’s computers, but also the surveillance cameras inside their building. “They [the U.S. ally] monitored the [Russian] hackers as they maneuvered inside the U.S. systems and as they walked in and out of the workspace, and were able to see faces, the officials said.”…
Infrastructure Vulnerabilities Make Surveillance Easy
Weakness in digital communications systems allows security to be bypassed, leaving users at risk of being spied on.
Governments want to spy on their citizens for all sorts of reasons. Some countries do it to help solve crimes or to try to find “terrorists” before they act.
Others do it to find and arrest reporters or dissidents. Some only target individuals, others attempt to spy on everyone all the time.
Many countries spy on the citizens of other countries: for reasons of national security, for advantages in trade negotiations, or to steal intellectual property.
None of this is new. What is new, however, is how easy it has all become. Computers naturally produce data about their activities, which means they’re constantly producing surveillance data about us as we interact with them…
Snoops May Soon Be Able to Buy Your Browsing History. Thank the US Congress
Think about all of the websites you visit every day. Now imagine if the likes of Time Warner, AT&T and Verizon collected all of your browsing history and sold it on to the highest bidder. That’s what will probably happen if Congress has its way.
This week, lawmakers voted to allow internet service providers to violate your privacy for their own profit. Not only have they voted to repeal a rule that protects your privacy, they are also trying to make it illegal for the Federal Communications Commission to enact other rules to protect your privacy online…
How to Keep Your Private Conversations Private for Real
Don't get doxed.
This essay also appeared in The Age.
A decade ago, I wrote about the death of ephemeral conversation. As computers were becoming ubiquitous, some unintended changes happened, too: Before computers, what we said disappeared once we’d said it. Neither face-to-face conversations nor telephone conversations were routinely recorded. A permanent communication was something different and special; we called it correspondence.
The Internet changed this. We now chat by text message and email, on Facebook and on Instagram. These conversations—with friends, lovers, colleagues, fellow employees—all leave electronic trails. And while we know this intellectually, we haven’t truly internalized it. We still think of conversation as ephemeral, forgetting that we’re being recorded and what we say has the permanence of correspondence…
The Value of Encryption
In today’s world of ubiquitous computers and networks, it’s hard to overstate the value of encryption. Quite simply, encryption keeps you safe. Encryption protects your financial details and passwords when you bank online. It protects your cell phone conversations from eavesdroppers. If you encrypt your laptop—and I hope you do—it protects your data if your computer is stolen. It protects your money and your privacy.
Encryption protects the identity of dissidents all over the world. It’s a vital tool to allow journalists to communicate securely with their sources, NGOs to protect their work in repressive countries, and attorneys to communicate privately with their clients…
Cryptography Is Harder Than It Looks

Writing a magazine column is always an exercise in time travel. I’m writing these words in early December. You’re reading them in February. This means anything that’s news as I write this will be old hat in two months, and anything that’s news to you hasn’t happened yet as I’m writing.
This past November, a group of researchers found some serious vulnerabilities in an encryption protocol that I, and probably most of you, use regularly. The group alerted the vendor, who is currently working to update the protocol and patch the vulnerabilities. The news will probably go public in the middle of February, unless the vendor successfully pleads for more time to finish their security patch. Until then, I’ve agreed not to talk about the specifics…
Data Is a Toxic Asset, So Why Not Throw It Out?
Thefts of personal information aren’t unusual. Every week, thieves break into networks and steal data about people, often tens of millions at a time. Most of the time it’s information that’s needed to commit fraud, as happened in 2015 to Experian and the IRS.
Sometimes it’s stolen for purposes of embarrassment or coercion, as in the 2015 cases of Ashley Madison and the U.S. Office of Personnel Management. The latter exposed highly sensitive personal data that affects security of millions of government employees, probably to the Chinese. Always it’s personal information about us, information that we shared with the expectation that the recipients would keep it secret. And in every case, they did not…
