In both a 2021 essay and my 2022 book, A Hacker’s Mind , I talk about AIs finding vulnerabilities and exploits—hacking—the legal system.

This essay was written with Cindy Cohn, and originally appeared in Lawfare. One of the many legacies of the terrorist attacks of Sept. 11 is the government-wide shift from targeted surveillance—such as individual wiretaps or pen register/trap and trace orders—to mass surveillance techniques—such as tapping into the…
The NSA has become too big and too powerful. What was supposed to be a single agency with a dual mission—protecting the security of U.S. communications and eavesdropping on the communications of our enemies—has become unbalanced in the post-Cold War, all-terrorism-all-the-time era. Putting the U.S. Cyber Command, the…
I was supposed to testify today about the TSA in front of the House Committee on Oversight and Government Reform. I was informally invited a couple of weeks ago, and formally invited last Tuesday: The hearing will examine the successes and challenges associated with Advanced Imaging Technology (AIT), the Screening of…
This morning, I spent an hour in a closed room with six members of Congress: Rep. Lofgren, Rep. Sensenbrenner, Rep. Bobby Scott, Rep. Goodlatte, Rep. Mike Thompson, and Rep. Amash. No staffers, no public: just them. Lofgren had asked me to brief her and a few Representatives on the NSA. She said that the NSA wasn’t…
Polish translation I’m going to start with three data points. One: Some of the Chinese military hackers who were implicated in a broad set of attacks against the U.S. government and corporations were identified because they accessed Facebook from the same network infrastructure they used to carry out their attacks…
In the span of just weeks, the US government has experienced what may be the most consequential security breach in its history—not through a sophisticated cyberattack or an act of foreign espionage, but through official orders by a billionaire with a poorly defined government role. And the implications for national…
For decades, I have been talking about the importance of individual privacy. For almost as long, I have been using the metaphor of digital feudalism to describe how large companies have become central control points for our data. And for maybe half a decade, I have been talking about the world-sized robot that is the…
Spanish translation Communities across the United States are starting to ban facial recognition technologies. In May of last year, San Francisco banned facial recognition; the neighboring city of Oakland soon followed, as did Somerville and Brookline in Massachusetts (a statewide ban may follow). In December, San…
An antidote to the American cycle of threat, fear, and overspending in response to terrorism is this, about Norway on the first anniversary of its terrorist massacre: And at the political level, the Prime Minister Jens Stoltenberg pledged to do everything to ensure the country’s core values were not undermined. “The…
We’re afraid of risk. It’s a normal part of life, but we’re increasingly unwilling to accept it at any level. So we turn to technology to protect us. The problem is that technological security measures aren’t free. They cost money, of course, but they cost other things as well. They often don’t provide the security…
I have a love/hate relationship with the Cato Institute. Most of their analysis I strongly disagree with, but some of it I equally strongly agree with. Last September 11—the tenth anniversary of 9/11—Cato’s David Rittgers published “Abolish the Department of Homeland Security“: DHS has too many subdivisions in too…
Last month, Attorney General William Barr gave a major speech on encryption policy—what is commonly known as “going dark.” Speaking at Fordham University in New York, he admitted that adding backdoors decreases security but that it is worth it. Some hold this view dogmatically, claiming that it is technologically…
For two days in September, Afghanistan had no internet. No satellite failed; no cable was cut. This was a deliberate outage, mandated by the Taliban government. It followed a more localized shutdown two weeks prior, reportedly instituted “to prevent immoral activities.” No additional explanation was given. The timing…
In an open letter, seven secure messaging apps—including Signal and WhatsApp—point out that the UK’s Online Safety Bill could destroy end-to-end encryption: As currently drafted, the Bill could break end-to-end encryption,opening the door to routine, general and indiscriminate surveillance of personal messages of…
Back in June, when the contents of Edward Snowden’s cache of NSA documents were just starting to be revealed and we learned about the NSA collecting phone metadata of every American, many people—including President Obama—discounted the seriousness of the NSA’s actions by saying that it’s just metadata. Lots and lots…
I don’t have a lot to say about the Sony hack, which seems to still be ongoing. I want to highlight a few points, though. At this point, the attacks seem to be a few hackers and not the North Korean government. (My guess is that it’s not an insider, either.) That we live in the world where we aren’t sure if any given…
Someone recently noticed a Washington Post story on the TSA that originally contained a detailed photograph of all the TSA master keys. It’s now blurred out of the Washington Post story, but the image is still floating around the Internet. The whole thing neatly illustrates one of the main problems with backdoors…
Interesting speculation that the NSA is storing everyone’s phone calls, and not just metadata. Definitely worth reading. I expressed skepticism about this just a month ago. My assumption had always been that everyone’s compressed voice calls is just too much data to move around and store. Now, I don’t know. There’s a…
Secret NSA eavesdropping is still in the news. Details about once secret programs continue to leak. The Director of National Intelligence has recently declassified additional information, and the President’s Review Group has just released its report and recommendations. With all this going on, it’s easy to become…
Yesterday, we learned that the NSA received all calling records from Verizon customers for a three-month period starting in April. That’s everything except the voice content: who called who, where they were, how long the call lasted—for millions of people, both Americans and foreigners. This “metadata” allows the…
Police are already using self-driving car footage as video evidence: While security cameras are commonplace in American cities, self-driving cars represent a new level of access for law enforcement and a new method for encroachment on privacy, advocates say. Crisscrossing the city on their routes, self-driving cars…
Last week, CIA director John Brennan told a Senate committee that there wasn’t any strong cryptography outside of the US. CIA director John Brennan told US senators they shouldn’t worry about mandatory encryption backdoors hurting American businesses. And that’s because, according to Brennan, there’s no one else for…
It turns out that the NSA’s domestic and world-wide surveillance apparatus is even more extensive than we thought. Bluntly: The government has commandeered the Internet. Most of the largest Internet companies provide information to the NSA, betraying their users. Some, as we’ve learned, fight and lose. Others…
Like many, I was surprised and shocked by the election of Donald Trump as president. I believe his ideas, temperament, and inexperience represent a grave threat to our country and world. Suddenly, all the things I had planned to work on seemed trivial in comparison. Although Internet security and privacy are not the…
In July 2012, responding to allegations that the video-chat service Skype—owned by Microsoft—was changing its protocols to make it possible for the government to eavesdrop on users, Corporate Vice President Mark Gillett took to the company’s blog to deny it. Turns out that wasn’t quite true. Or at least he—or the…
Persuasion is as old as our species. Both democracy and the market economy depend on it. Politicians persuade citizens to vote for them, or to support different policy positions. Businesses persuade consumers to buy their products or services. We all persuade our friends to accept our choice of restaurant, movie, and…
We’re in the middle of an epic battle for power in cyberspace. On one side are the traditional, organized, institutional powers such as governments and large multinational corporations. On the other are the distributed and nimble: grassroots movements, dissident groups, hackers, and criminals. Initially, the Internet…
This isn’t phishing; it’s not even spear phishing. It’s laser-guided precision phishing: One of the leaked diplomatic cables referred to one attack via email on US officials who were on a trip in Copenhagen to debate issues surrounding climate change. “The message had the subject line ‘China and Climate Change’ and…
If there’s any confirmation that the U.S. government has commandeered the Internet for worldwide surveillance, it is what happened with Lavabit earlier this month. Lavabit is—well, was—an e-mail service that offered more privacy than the typical large-Internet-corporation services that most of us use. It was a small…
Useful best practices for malware writers, courtesy of the CIA. Seems like a lot of good advice. General: DO obfuscate or encrypt all strings and configuration data that directly relate to tool functionality. Consideration should be made to also only de-obfuscating strings in-memory at the moment the data is needed…
