Remote user or browser plug-in
Hello All,
A few days ago I was using Safari browser on an iMac( 2016 version running Sierra) when I had to fight for control of the mouse. It seemed there was a remote user fooling around with the browser opening menu items, checking out bookmarks inthe favorites bar, and even deleting a bookmar and closing a tab. I was able to close all open applications and shut down the machine. I waited and then rebooted and everything seemed back to normal. I did a complete scan and nothing was detected. How can an intruder get in the machine undetected like that? It only seemed to affect the browser.

Hello,
Sorry for my reply. I'm also only F-Secure user (their home solutions);
Also I'm not friendly with Mac/iOS platforms - so I not sure about many of points, but I just briefly search web by some words from your situation;
And if it was not a random (even not sounds like this) -> maybe good to doublecheck about potential installed addons/extensions or applications (or just some other scans - if Mac platform able to do with trusted on-demand scanners, as example); Or re-check some system's settings;
At least, possible to get an answer about your ask:
How can an intruder get in the machine undetected like that? It only seemed to affect the browser.
with many different words.
As example, some articles/pages about abilities (which can be used for such view); Maybe most of them should be known for you (and some of them about 'conceptions' only). From certain malware to 'valid' installed application or addons/extensions (under system or browser); Also some default(?) features like remote control by iPad/iPhone; OR certain features under Mac/iOS design;
But probably all of this with limitations like: you have to do so; or someone - who able to use your device/network; With other meanings -> it should be something what security software should to detect (and if it undetected.....maybe possible to investigate it more);
Thanks!
