Apple Mac Computers are considered to be much safer than Windows at keeping viruses and malware out of its environment, but that’s simply not true anymore.
It’s not because Mac OS X is getting worse every day, but because hackers are getting smart and sophisticated these days.

The bad news for Mac users is that malware targeting webcams and microphones has now come up for Mac laptops as well.
Patrick Wardle, an ex-NSA staffer who heads up research at security intelligence firm Synack, discovered a way for Mac malware to tap into your live feeds from Mac’s built-in webcam and microphone to locally record you even without detection.
Jan 30, 2019 How to see if your webcam is being hacked You can check to see if your webcam is in use in a few ways. The easiest way on some webcams, notably the type that you attach to your laptop, is to see if. If your webcam light turns on a few seconds after you reboot your computer, without launching any applications – you might’ve been hacked. If this is what’s happening, move on to the next step. Step 4: See if your webcam process is running.
For each account, Mac OS X will list the time and date of the last login to all existing accounts. If the most recent login to any of the accounts happened at an abnormal time, it probably was done by a hacker masquerading as a legitimate user.
Wardle is the same researcher who has discovered a number of security weaknesses in Apple products, including ways to bypass the Gatekeeper protections in OS X.
Wardle also released a free tool called RansomWhere? earlier this year that has generic detection capabilities for Mac OS X ransomware variants.
Wardle is scheduled to present his new findings at the Virus Bulletin conference in Denver later today, along with his research demonstrating how malware could easily piggyback on your legitimate webcam sessions to keep its spying activity hidden.
Yes, piggybacking legitimate webcam sessions initiated by you.
Here’s How Mac Malware Works:
Since Mac’s firmware-level protection lights the green LED for any unauthorized access to user’s webcam, Wardle believes that attackers can use a malicious app that quietly monitors the system for any outgoing feed of an existing webcam session – like a Skype or FaceTime call – where the light indicator would already be ON.
The malware then piggybacks the victim’s webcam or microphone to secretly record both audio and video session, without any visible indication of this malicious activity and any fear of detection.
In his paper presentation, titled ‘Getting Duped: Piggybacking on Webcam Streams for Surreptitious Recordings,’ Wardle outlines the threat along with countermeasures to detect “secondary” processes that try to access an existing video session on OS X.
How to Prevent Your WebCam and Mic from Being Hacked
Wardle has developed and released a free tool, dubbed OverSight, which not only monitors webcam and microphone activities but also alerts you when a secondary process accesses your webcam, asking whether you want to allow or block access.

Moreover, physically covering your webcam – like what Facebook CEO Mark Zuckerberg and FBI Director James Comey do – also offers a low-tech approach to keeping snoopers away. Text to mp3 converter download.
I am very suspicious that I am being hacked..like the kind where they can watch your screen and see through your webcam. How would I go about checking to see if this is true? Is there a way?
My computer has been freezing up and three times now a message box has popped up with the icon of the yellow triangle with an exclamation point inside, but before I can read what it says or manually close it, it goes away...

Also, I had posted this question before, along with a similar post on here yesterday, and they were beginning to receive comments back, and now they're gone. I haven't deleted anything from here, so does apple remove my posts, or is someone else..?
Any help is appreciated. Thanks!
