Tracking our faces and whereabouts is getting out of control. It’s a mass surveillance infrastructure that keeps growing in Borg-like fashion. Facial recognition and license plate readers are proliferating at a stupefying pace and companies like Flock are consolidating the collected data and packaging it up for sale to law enforcement agencies. Even if no human in these agencies were to abuse this data, it’s creating an irresistible target for scheming hackers and nation states keen on espionage. The longer we let this go, the harder it will be to stop.

In today’s news: Asus routers are being hacked and you need to take action; 23andMe has been sold, along with its users’ genetic data; AI-generated videos have just become way more realistic; US government taps surveillance company to centralize all its citizen data; CFPB regulation limiting data brokers is axed; Kroger is packaging and selling its customer loyalty data; automated license plate reader data use is expanding in scary ways; Android phones gain key new security feature; EU court rules that real-time bidding data gathering is illegal; Montana is first state to plug data broker loophole; and I relate my recent privacy experience at the US border.

VPNs were not invented for privacy, despite the name – they were invented for security. Nevertheless, in recent years, they have been touted as privacy tools to thwart rampant and fanatical data gathering. With a regular VPN, this really just means you’re shifting your trust from your internet service provider to your VPN provider. But what if your encrypted data traffic was actually divided between two separate companies? The split trust model is a powerful way to protect your privacy and it’s the key technology behind new services like Apple’s Private Relay and Obscura VPN. Today we’ll discuss the benefits of this approach with Obscura’s founder, Carl Dong.

There are way too many messenger apps today. It’s a sad state of affairs and I don’t see it getting better anytime soon. But the real problem (for me) is that almost all of the popular messenger apps aren’t really that secure and private. Most do not have end-to-end encryption (E2EE) at all or it’s not turned on by default. And frankly even the apps with E2EE are run by companies whose revenue model is based on monetizing your personal data. I’m going to suggest you try Signal.

Almost exactly two years ago, “Five Eyes” intelligence agencies discovered a successful and ongoing cyber attack on critical US infrastructure by a state-sponsored actor based in China. This group, associated with the People’s Liberation Army and known as Volt Typhoon, was tasked with quietly gaining persistent remote access to critical systems including water, power, communications, and transportation systems, as well as ports and government networks. The goal was to deter the US from interfering with a future invasion of Taiwan by China, either by crippling the US infrastructure or threatening to. Despite dire warnings from the four top cyber officials in a Jan 2024 Congressional hearing, the US is still woefully unprepared for such attacks. Josh Corman is leading an effort labeled UnDisruptable27 to greatly improve the resilience of our critical systems before 2027, the year China seems to be targeting to make their move.

As we learned last week from Zach Edwards, our smartphones have a globally unique mobile ad ID, or MAID, that is automatically associated with everything we do on our phones… unless we take explicit steps to turn this off. Today I’ll tell you how this works and why you should disable this insidious form of tracking.

In other news: the FTC warns us about a new type of scam; dating app Raw exposed sensitive user data; a determined reporter documents his efforts to disable all the AI features in his Google phone; “juice jacking” is back with a tricky twist; Apple’s AirPlay has a vulnerability whose fix may not reach all devices; Microsoft is pushing hard for passwordless accounts; Google Wallet allows you to verify your age without giving up personal info; and there’s a new and troubling update to the Signalgate saga.

Data brokers are out of control. While we think of them gathering data in order to target us with ads, they can actually use the targeted ad system (real-time bidding) to collect vast quantities of personal information. It’s a very shady business and the primary players are trying hard to obfuscate what they’re doing. Thankfully, we have people like my guest, Zach Edwards, whose investigations are ripping the cover off of these unscrupulous practices.

Going through border security today – even just returning to your own country – is not at simple and stress-free as it should be. The likelihood of our digital devices being searched by a border agent has increased in recent years and political sensitivities today can be high. Our devices have access to a ridiculous amount of extremely personal information. How can we protect ourselves? The answers aren’t great, but I’ll give the current best advice from immigration lawyers and civil rights groups.

In other news: the Apple-UK data privacy court case will be at least partially public; some companies are ignoring automated opt-out signals; Waymo may use interior car video to train its AI; data breaches at Hertz and a Planned Parenthood medical lab; air travel group paints a picture of future use of facial recognition; San Francisco police have a new surveillance center; Ukraine drones come with anti-Russian malware; judge rules that ‘cell tower dumps’ require a warrant.

It’s easy to be a Monday morning quarterback, even with cybersecurity. But defending a business, of any size, against cyber threats today is hard. Like, really hard. Defenders have to succeed every single time; attackers only need to succeed once. And then your company makes the headlines. Today we’ll delve into the world of the “blue team” – the defenders who are charged with protecting your data and the services you depend on – with cyber expert Oz Jones. Along the way, we’ll learn valuable lessons for everyone.

When we collect a lot of personal data, say via the US Census, the goal is to glean important aggregate information and statistics, while somehow preserving the anonymity and privacy of the individual respondents. There’s a rigorous mathematical process for doing this – that’s actually not that hard to understand – called Differential Privacy. I’ll explain how it works.

In the news: iOS has a new location privacy setting; Google confirms it’s rolling out AI to Gmail; Windows makes it much harder to avoid creating a Microsoft Account; WhatsApp is rolling out AI in Europe with no way to opt out; Switzerland is considering undermining encrypted communications; 23andMe is going bankrupt – it’s time to delete your data; France rejects a backdoor mandate; and finally, I have a lot to say about the US officials’ Signal chat debacle.

We’ve been installing apps on our smartphones for almost two decades now. The iPhone and Android app stores kicked off in 2008 and we still, to this day, have no real way to know what’s in them. It turns out that most apps are an amalgamation of software libraries and development kits from various third party vendors, so often even the makers of apps don’t fully understand the makeup of their products. Lisa LeVasseur from Internet Safety Labs has worked to build tools to dissect and inspect our apps and help us understand what they’re really doing.
