https://www.wired.com/story/inside-the-nsas-secret-tool-for-mapping-your-social-network/<p>While reading the article, my screen went blank, displayed a spinner, then went to the lock screen.

Is this just a random fluke, or was something served from the wired website to cause this?
I have heard news about recent security breaches with ios Mail app and push notifications. Apple managed to patch it earlier this month. Could be related to that but it was not for browser.
