Aug 31, 2016 If you're one of those people who gets made fun of for putting a piece of tape over your webcam, don't worry—you're not crazy. Unfortunately, your paranoia is justified, since it is, in fact, possible for the internet's elite lets call them to sec. Here's how you can stop someone from accessing your Mac’s webcam. Zoom vulnerability: Mac webcams could have been hacked. Including activating their Mac’s webcams. May 20, 2020 However, webcams can also be used by hackers to spy on you. Any webcam, including built-in laptop and phone cameras, can be hacked and used for webcam spying. It’s easy to think you’re safe from hacking on a private network, but without extra security, you. Im not sure about built-in webcams, but I think it is most likely possible. I've found info on Logitech Webcams, where you can turn off the LED in the registry keys. For QuickCam versions 11.5.0.1169 thru 11.9.0.1263, LVUVCLEDControl is located in the following registry key.
Apple’s iOS and macOS are always considered to have better security than Android and Windows, but not all the time. A security researcher found a zero-day vulnerability in the Safari browser, which has seven different flaws that may allow any remote hacker to access users’ microphone, camera, location and even saved passwords. And being a Zero-day, there were no exploitations yet and Apple rewarded the finder a bounty of $75,000.
Rayn Pickren, a security researcher has surfaced seven different flaws from Apple’s Safari browser that may allow any hacker to the bluff user and the browser to spy on you. As we all knew, any app for functioning needs certain permissions like access to the microphone, camera, gallery, storage, etc. These were allowed by the user manually and could deny anytime he wants. But, few flaws in the Safari browser let this consent go out of hand.

Safari being insecure
An error in Safari’s hostname parsing blurs the differentiation between authentic and malicious websites. This allows hackers to craft a fraudulent website that resembles legitimate sites and have their permissions reflected to them. For example, a user letting camera and microphone permission to Skype is normal, which was stored by Safari as the user allowed so. And the next time when he visits Skype, Safari would directly let the user go onto video by default.
And when a hacker crafts a malicious site resembling Skype, this could fool Safari. He may add meaningless hostnames like file: javascript: or data: to fool Safari as a legitimate site. Simply, Safari has failed to check the website’s origin policy, which should be coming from the same. Further, this would let the hacker gain plaintext passwords too! But, there’s a limitation. This trick works only when the websites are currently opened.
Patch is available
These flaws were informed to Apple by Ryan a while back, and Apple has released patches for them in subsequent updates. These were pushed in Safari version 13.0.5 (28th January 2020) and version 13.1 (24th March 2020), where users are recommended to update immediately to avoid being exploited.

Q. I’m getting a Chromebook. There’s no malware on that, right?
A. Google has earned the right to brag a little about the security built into its browser-based Chrome OS that runs on cheap, light and increasingly popular Chromebook laptops.
As the company explains in a tech-support note, Chrome OS closes off most traditional entry points for malware. You can’t install traditional programs at all, the browser and individual pages run locked inside “sandboxed” areas of memory, and at each reboot, a Chromebook verifies that its software hasn’t been tampered with and repairs it if necessary.
Chrome OS also downloads and installs its own security updates automatically. And since it stores your data online, even setting a Chromebook on fire should not jeopardize your info.
But all of those features don’t reduce the “attack surface” of Chromebooks to zero: An adversary can still exploit features of Chrome OS, and of your brain, for ill purposes. At a minimum, a hostile page can still try to lock up your browser and leave it stuck on a demand that you pay up. As a Google advisory notes, you can escape that by resetting the Chromebook, then restarting Chrome while declining its option to restore earlier open pages.
That kind of page hijacking can also present the user with a prompt to install a malicious third-party extension—a browser add-on that runs inside of Chrome.
“We are seeing more and more aggressive malicious advertising (malvertising) campaigns that trick or force users to install bogus extensions,” said Jérôme Segura, lead malware-intelligence analyst at the security firm Malwarebytes. Last year, he found one such extension had been downloaded over a thousand times before Google yanked it from the Chrome Web Store.
The newfound ability of Chrome OS to run Android apps—it’s confined to a few recent Chromebooks now, but this feature announced last summer should soon arrive on more models—adds an exceedingly low but non-zero possibility of infection. Android malware exists and can sweep across phones in vast quantities, but almost all of it arrives via third-party app stores, not Google’s Play Store. But some malicious apps sneak in, just as they rarely do in Apple’s iOS App Store.

Segura added that a Chromebook remains as vulnerable as any other computer to “man-in-the-middle” attacks, in which a hostile WiFi network (or a wireless router that’s been remotely hacked) can start spying on your Web traffic or redirecting it to other malicious sites. Using a virtual private network service to shield and encrypt your connection will stop that threat, although VPNs often cost extra.
Finally, phishing e-mails and other types of “social engineering” ploys that try to fool you into giving up a password or other valuable data don’t care what software you run. They only prey on your own mind. The best defense against them remains a healthy skepticism towards solicitations on the screen that you weren’t expecting. That, in turn, remains good advice for keeping any other computer secure.
