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.

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.

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.

Tax time is once again upon us here in the USA, which means that the tax scammers are coming out of the woodwork. Many will claim to be representing the IRS, claiming that there is an urgent need to fix a problem with your return, threatening penalties if you don’t pay them money. Others will simply try to file fake returns in your name, but send the massive false refund checks to themselves. I’ll help you spot and avoid these scams.

In other news: Apple’s Passwords app was vulnerable to phishing attacks (now fixed); Amazon is forcing Echo owners to share voice recordings; the Bluetooth chip “backdoor” that wasn’t; Captchas were used by Google to translate books and Street View images; ICE uses third party tool to scrape tons of your data; beware of online file converters; Clearview AI attempted to buy millions of mugshots; RCS messaging will soon allow end-to-end encrypted chats between iPhones and Android phones.

Josh Summers lived in China for many years and learned a lot about privacy and security. Since he left, he’s made it his mission to share this knowledge through his website and YouTube channel called All Things Secured – helping regular, everyday people like you and me to protect our data and devices. Today we’ll talk specifically about improving your security and privacy on iPhones and Android phones, and even some alternatives outside the Apple and Google ecosystems.

Google’s Chrome browser is rolling out changes that will hamstring ad blockers – so there’s never been a better time to try a better browser. There are a handful of good options, but I’m going to recommend that you try Firefox with a fantastic ad blocker called uBlock Origin. If you’ve never tried this powerful combination, you won’t believe what you’ve been missing.
