Google's Four-Fecta of Critical Zero-Day Bugs
Google has just revealed a four-fecta of critical zero-day bugs affecting a wide range of Android phones, including some of its own pixel models. I've got an update on that, but it's not looking like it's ready for prime time yet. And then we'll get to my tip of the week where I'll talk about device fingerprinting or web fingerprinting or browser fingerprinting.
Marketers are desperately trying to follow us as we traverse the web. Tracking where we go and what we do allows them to better target us with ads. Browsers have built in protections to block older tracking techniques like cookies and tracking pixels, and so ad companies have had find new methods for identifying us across websites. Unfortunately, they’ve settled on a technique that is extremely difficult to defeat: fingerprinting. I’ll explain what is, how it works, and what you can do to mitigate it.
In other news: Google is warning Android users to update their devices right away in order to fix some truly nasty bugs; hackers are using malicious Chrome extensions to read your Gmail and potentially hack your Android device; popular fertility apps are collecting ridiculous amounts of highly personal data and sharing it with partners; scammers are using AI to simulate voices of people you know to steal your money; CISA has launched a great new ransomware vulnerability pilot program; I’ll tell you why you should opt out of sharing your data with your mobile service provider; America’s threatening to ban TikTok but this won’t fix the real problem; the IRS is supposed to be moving away from ID.me authentication.
