People get their identities stolen every day, and it is a super, super, super shitty process to go through depending on how deep it goes. It can change your life forever.
Having oldass OS and application versions make that a thousand times easier when you have so, so, so many CVEs you can exploit. And LLMs have been show to make this very trivial now.
All you need to do is click on the wrong pop-up, or the wrong link in your email, or tap something on your phone screen, or have a poorly configured (often from the factory) router, and the initial intrusion takes place. After that, an outbound encrypted session quickly gets setup, and congrats, now your network is acting as a residential proxy that can be sold to criminals that want to download CSAM from your IP, AI companies that will use your connection for scraping, and other elements that will either mine the data on your systems (your PII, logins, etc) and scrape your screens.
But if you don't care about your life becoming a living hell, then I can't make you.
This happens all the time, every day.
If you have a car, you maintain it. If you have a bike, you maintain it. Power tools? You maintain them. Your electronic devices also need to be maintained. They have access to your most sensitive data, and potentially private conversations.
