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.

China Spying on Undersea Internet Cables

Supply chain security is an insurmountably hard problem. The recent focus is on Chinese 5G equipment, but the problem is much broader. This opinion piece looks at undersea communications cables: But now the Chinese conglomerate Huawei Technologies, the leading firm working to deliver 5G telephony networks globally…

Surveillance and the Internet of Things

The Internet has turned into a massive surveillance tool. We’re constantly monitored on the Internet by hundreds of companies—both familiar and unfamiliar. Everything we do there is recorded, collected, and collated—sometimes by corporations wanting to sell us stuff and sometimes by governments wanting to keep an eye…

Finding Sociopaths on Facebook

On his blog, Scott Adams suggests that it might be possible to identify sociopaths based on their interactions on social media. My hypothesis is that science will someday be able to identify sociopaths and terrorists by their patterns of Facebook and Internet use. I’ll bet normal people interact with Facebook in ways…

Can I Be Trusted?

Slashdot asks the question: I’m a big fan of Bruce Schneier, but just to play devil’s advocate, let’s say, hypothetically, that Schneier is actually in cahoots with the NSA. Who better to reinstate public trust in weakened cryptosystems? As an exercise in security that Schneier himself may find interesting, what…

Detaining David Miranda

Last Sunday, David Miranda was detained while changing planes at London Heathrow Airport by British authorities for nine hours under a controversial British law—the maximum time allowable without making an arrest. There has been much made of the fact that he’s the partner of Glenn Greenwald, the Guardian reporter whom…

Volkswagen and Cheating Software

Portuguese translation by Ricardo R Hashimoto For the past six years, Volkswagen has been cheating on the emissions testing for its diesel cars. The cars’ computers were able to detect when they were being tested, and temporarily alter how their engines worked so they looked much cleaner than they actually were. When…

Excess Automobile Deaths as a Result of 9/11

People commented about a point I made in a recent essay: In the months after 9/11, so many people chose to drive instead of fly that the resulting deaths dwarfed the deaths from the terrorist attack itself, because cars are much more dangerous than airplanes. Yes, that’s wrong. Where I said “months,” I should have…

Feudal Security

It’s a feudal world out there. Some of us have pledged our allegiance to Google: We have Gmail accounts, we use Google Calendar and Google Docs, and we have Android phones. Others have pledged allegiance to Apple: We have Macintosh laptops, iPhones, and iPads; and we let iCloud automatically synchronize and back up…

The Insecurity of Secret IT Systems

We now know a lot about the security of the Rapiscan 522 B x-ray system used to scan carry-on baggage in airports worldwide. Billy Rios, director of threat intelligence at Qualys, got himself one and analyzed it. And he presented his results at the Kaspersky Security Analyst Summit this week. It’s worse than you might…

Frequent Password Changes Is a Bad Security Idea

I’ve been saying for years that it’s bad security advice, that it encourages poor passwords. Lorrie Cranor, now the FTC’s chief technologist, agrees: By studying the data, the researchers identified common techniques account holders used when they were required to change passwords. A password like “tarheels#1”, for…

What I've Been Thinking About

I’m starting to think about my next book, which will be about power and the Internet—from the perspective of security. My objective will be to describe current trends, explain where those trends are leading us, and discuss alternatives for avoiding that outcome. Many of my recent essays have touched on various facets…

A Hardware Privacy Monitor for iPhones

Andrew “bunnie” Huang and Edward Snowden have designed a hardware device that attaches to an iPhone and monitors it for malicious surveillance activities, even in instances where the phone’s operating system has been compromised. They call it an Introspection Engine, and their use model is a journalist who is…

The NSA is not made of magic (2014)

I am regularly asked what is the most surprising thing about the Snowden NSA documents. It’s this: the NSA is not made of magic. Its tools are no different from what we have in our world, it’s just better-funded. X-KEYSCORE is Bro plus memory. FOXACID is Metasploit with a budget. QUANTUM is AirPwn with a seriously…

Schneier on Security: Recording the Police

I’ve written a lot on the “War on Photography,” where normal people are harassed as potential terrorists for taking pictures of things in public. This article is different; it’s about recording the police: Allison’s predicament is an extreme example of a growing and disturbing trend. As citizens increase their…

No, RSA Is Not Broken

I have been seeing this paper by cryptographer Peter Schnorr making the rounds: “Fast Factoring Integers by SVP Algorithms.” It describes a new factoring method, and its abstract ends with the provocative sentence: “This destroys the RSA cryptosystem.” It does not. At best, it’s an improvement in factoring—and I’m not…

Insecurities in the Linux /dev/random

New paper: “Security Analysis of Pseudo-Random Number Generators with Input: /dev/random is not Robust, by Yevgeniy Dodis, David Pointcheval, Sylvain Ruhault, Damien Vergnaud, and Daniel Wichs. Abstract: A pseudo-random number generator (PRNG) is a deterministic algorithm that produces numbers whose distribution is…

Bounty to Recover NIST's Elliptic Curve Seeds

This is a fun challenge: The NIST elliptic curves that power much of modern cryptography were generated in the late ’90s by hashing seeds provided by the NSA. How were the seeds generated? Rumor has it that they are in turn hashes of English sentences, but the person who picked them, Dr. Jerry Solinas, passed away in…

I'm Writing a Book on Security

I’m writing a book on security in the highly connected Internet-of-Things world. Tentative title: Click Here to Kill Everybody Peril and Promise in a Hyper-Connected World There are two underlying metaphors in the book. The first is what I have called the World-Sized Web, which is that combination of mobile, cloud…

Who Does Skype Let Spy?

Lately I’ve been thinking a lot about power and the Internet, and what I call the feudal model of IT security that is becoming more and more pervasive. Basically, between cloud services and locked-down end-user devices, we have less control and visibility over our security—and have no point but to trust those in power…

Security Risks of TSA PreCheck

Former TSA Administrator Kip Hawley wrote an op-ed pointing out the security vulnerabilities in the TSA’s PreCheck program: The first vulnerability in the system is its enrollment process, which seeks to verify an applicant’s identity. We know verification is a challenge: A 2011 Government Accountability Office report…

Blockchain and Trust

In his 2008 white paper that first proposed bitcoin, the anonymous Satoshi Nakamoto concluded with: “We have proposed a system for electronic transactions without relying on trust.” He was referring to blockchain, the system behind bitcoin cryptocurrency. The circumvention of trust is a great promise, but it’s just…

Worst-Case Thinking

At a security conference recently, the moderator asked the panel of distinguished cybersecurity leaders what their nightmare scenario was. The answers were the predictable array of large-scale attacks: against our communications infrastructure, against the power grid, against the financial system, in combination with…

Security in 2020

There’s really no such thing as security in the abstract. Security can only be defined in relation to something else. You’re secure from something or against something. In the next 10 years, the traditional definition of IT security—­that it protects you from hackers, criminals, and other bad guys—­will undergo a…

Cell Phone OPSEC for Border Crossings

I have heard stories of more aggressive interrogation of electronic devices at US border crossings. I know a lot about securing computers, but very little about securing phones. Are there easy ways to delete data—files, photos, etc.—on phones so it can’t be recovered? Does resetting a phone to factory defaults erase…
