New Year’s Resolutions 2025!

The start of a new year is always a good time to add some big juicy goals to your to-do list – call them New Year’s Resolutions, if that works for you, but really it’s just about making up your mind to tackle some important personal objectives. Today I’ll give you several ideas to improve your privacy and security in 2025, and those around you. In the news: dozens of malicious Chrome Browser extensions identified; net neutrality is dead, again, and probably for good this time; Apple to pay a me...

ALPRs Are Everywhere

There are many ways in which we are tracked in the real world, but one of the most ubiquitous and insidious technologies is Automated License Plate Readers. These camera systems are deployed in just about every city by both public and private organizations. Furthermore, the third parties who sell and operate these systems collect and collate data from around the country, making it available to law enforcement and marketing firms. Because these systems capture images of your car, they can also do...

Replay: Golden Age of Surveillance

I’m digging into the vault for a classic replay! I first interviewed Phil Zimmermann, creator of Pretty Good Privacy (PGP), on May 7, 2018. It was Episode 63 (we’re now at 408) and it was entitled “We Now Live in the Golden Age of Surveillance”. In this episode we talk a little about the origins of PGP in the 1990’s and what he feels about the FBI’s claims that we’re “going dark” due to strong end-to-end encrypted communications. I’ve added some new commentary, but the original episode is preser...

Deleting Your Data

Have you ever searched for your personal information online? There are dozens of “people search sites” out there, but a simple Google search can also find information about you, too. Behind the scenes, there are hundreds if not thousands of data brokers who are scouring the web constantly for your info creating dossiers on all of us, for sale to anyone willing to pay. We have no federal privacy laws in the US, but even if you live in the EU (with GDPR) or a US state with some privacy protections...

Letters from the Mailbag

It’s been too long since I’ve dipped into the listener mailbag, so today I’m going to answer a small selection of your questions on the air! Topics include privacy-respecting baby monitors, the “IoT network” on some Orbi routers, why you can’t really use a computer monitor as a “dumb” TV, and whether browser privacy plugins work on first party tracking. We’ll also cover some news stories: why you shouldn’t upload medical images to AI chatbots; the Fancy Bear “nearest neighbor” attack; Google’s ...

Privacy is Power

Privacy has been defined in many ways. The right to tell your story your own way. The right to have control over your personal information. The right to be left alone. There’s a reason we have T-shirts that say “dance like no one is watching”. We censor ourselves when we’re being watched. But if knowledge is power, then asymmetries in knowledge must lead to asymmetries in power. Privacy is a human right but it’s also a collective good – something we need to respect and support, even if we do not...

Holiday shopping season is here! And today I’ll give you the highlights of my annual Best & Worst Gift Guide for 2024, with regard to privacy and security. The worst offenders may not surprise you, though some have actually gotten worse since just last year. And I have a few new suggestions for people on your nice list! In the news this week: another popular browser extension has gone rogue; Mozilla laid off 30% of their staff; FBI warns that bad guys are filing fraudulent emergency data reques...

Cutting the Software Tether

Device manufacturers are breathing new life into old mundane products by connecting them to the internet, giving us the ability to monitor and control them from anywhere. However, this connection to the cloud works both ways. Not only do device makers now have unprecedented access to our usage and personal information, but they can hobble or limit our use of these devices at their whim. Today I’ll speak with IoT expert Stacey Higginbotham who is working with Consumer Reports and other consumer r...

Curbing Location Tracking

Our location is being tracked mercilessly today, in several ways. In the digital age, location data is among the most sensitive information we share, providing a record of our daily lives that can reveal where we live, who we associate with, and our personal routines. For app developers, marketers, and even law enforcement, this data is a goldmine for the ‘app economy’. Today I’ll talk about the most common sources of location data and give you some tips for limiting the tracking. In other news...

Understanding AI Chatbots

Artificial Intelligence (AI) is the buzzword of the day. There are many types of AI, but one particular flavor is getting a lot of press these days: chatbots. Formally referred to as Large Language Models (LLMs), chatbots like ChatGPT, Claude and Gemini are everywhere – either directly or integrated with other popular apps. This technology is real and it’s here to stay, so it’s important that we understand what it is, how it works, and what the limitations are. Today I’ll explore some aspects of...

L0pht Heavy Industries

L0pht Heavy Industries (pronounced “loft”) was one of the most influential hacker groups in history. Unlike many others, L0pht carefully cultivated a relationship with mass media, sold profitable products, started businesses, and even testified before the US Senate. Cris Thomas, aka Space Rogue, was one of the earliest members of the L0pht and he recently published a book chronicling the groups long and storied history called Space Rogue: How the Hackers Known As L0pht Changed the World. Today I...

Indicators of Account Compromise

Sometimes it’s obvious when your accounts are hacked. Maybe your money is gone. Maybe you can no longer log in using the password you know is correct. Maybe everyone you know has gotten a scam email from you that you didn’t send. But sometimes bad guys aren’t so obvious. They may lurk around in your accounts to gather information for identity theft or in hopes of gaining access to other more lucrative accounts. I’ll tell you how to find out. In other news: CA governor vetoes opt-out signal bill...

TunnelVision, VPNs and You

Two security researchers showed how many modern VPN services are vulnerable to malicious misconfiguration, exposing some or all of your internet traffic. While this is not likely to impact most of us, it does expose the limitations of Virtual Private Networks and why they are not silver bullets for security of privacy – despite many marketing claims to the contrary. Today we’ll discuss how TunnelVision works, how it can be mitigated, and how this affects different privacy threat models with the ...

Malware Reboot Remedy

We often think of malware as a problem for our computers and perhaps our smartphones. But bad guys love to hack our home routers and IoT devices, as well. Thankfully, purging malware from those types of devices can usually be done just by rebooting them. (There’s a reason tech support always asks you to try turning your device off and back on again.) I’ll explain why this works and what you should do to protect your connected devices. In other news: I explain why most people are not in danger o...

Post-Quantum Crypto

You may be vaguely aware of the term ‘quantum computing’ from media reports. But what you may not have picked up on is that one of the primary uses for quantum computers may be to break data encryption. Furthermore, you may not realize that if three-letter agencies can save off our encrypted emails and messages now, this could mean they could read them in the future when sufficiently powerful quantum computing becomes viable. How does this work? And what can we do about it now to protect our pri...

The Truth is Out There

Mis- and disinformation is just a fact of modern life, but certain events can cause the practice to significantly increase – like a big election. This is a good time to review this phenomenon, learning how to recognize it, how to avoid being drawn in, and perhaps most importantly how to reduce its spread. In other news: Telegram’s CEO was arrested in France; too many people keep saying Telegram is an secure messaging app when it’s really not; if you think ads and tracking are bad now, wait till...

Crazy Proton Summer

Proton released three major new products this summer, all within the span of about a couple months: Proton Docs, Proton Wallet and Proton Scribe. Given that Proton is a privacy-focused company, some of these offerings seemed almost at odds with that mission. So today I ask Andy Yen (Proton’s CEO) some questions about the privacy of their Bitcoin wallet and AI editing tool. We also discuss the new Proton Foundation and how it safeguards their privacy mission for the future. Finally, I ask Andy if...

National Public Data Breach

The headlines have been on fire with stories about 3 billion people’s data being leaked from a company you’ve never heard of. But like many such stories, the mainstream media gets a lot of the important details wrong and glosses over a lot of the important nuances. Today we’re going to dive into what really happened and what you should do about it, whether your data was part of the breach or not. In other news: Illinois waters down its landmark biometric information law; US court rules geofence...

Dating App Privacy

Finding your soul mate or even just a one-night stand can all be done digitally now – there’s an app for that. Several, in fact. But in order to find the best match, you need to turn over a lot of extremely personal information. You probably also need to let the app track your location, so you’re only matching people within some acceptable distance. You would hope that dating apps would be better than other apps at securing your private data… but are they? And are these services selling my data ...
