Phishing
I just saw some calendar notes on my calendar that says “Your information have been exposed to everyone” and I have to click on it to install the anti-malware app which I obviously did not do. But I ran the link on my laptop using an incognito web browser and it did open up a link to install the app. I closed the browser and did nothing to the app. I did not install it. But how was I able to get calendar notes on phone without me knowing? Does that mean someone already has an access to my phone remotely?
