It's possible to stream a MacBook's entire computer screen without using Apple's Screen Sharing application and without opening any ports on the target device. A hacker with low user privileges on the backdoored Mac may be able to view a victim's every move in real time no matter where they are.
Continuing the hacking macOS series, in this article, I'll show how to covertly stream a MacBook's desktop to an attacker's system so they can watch the user's every move in real time without using Apple's Screen Sharing functionality. This assumes that the attacker has already configured a backdoor on the target Mac. Below is an example GIF of the attack in action.
How To Hack A Mac Camera
Such an attack is utilized by penetration testers gathering behavioral information about a target user and possibly to use discovered information to further exploit the device, the Wi-Fi network, and information about the target's personal and work life. Black hat hackers would also use such tactics to blackmail a user by leveraging private email, chats, iMessages, and web browsing habits that may embarrass the victim in their professional or social life.
So, now you know how a hacker can stream audio and video from a backdoored MacBook. But we're not done hacking Macs yet. There's a lot more to explore besides what we've covered already, so keep coming back and keep an eye out for more Mac hacks.

Hackers, researchers have discovered, can use a piece of software called a Remote Administration Tool to get around that security feature. RAT allows people to control a computer from anywhere on the Internet to turn on the iSight camera without turning on the light.
Can a MacBook camera be on without light? Apple assures its customers that the FaceTime HD camera cannot be used without enabling the indicator light. However, cybercriminals are constantly finding software vulnerabilities and overcoming security safeguards, making it essential for users to watch out for other signs of webcam hacking. All-in-one security software.
Note that cybercriminals can store pictures and videos in random folders on your Mac. Thus, the lack of suspicious media materials in the Photos Library folder does not necessarily mean your device is safe from hackers.
Camfecting or webcam hacking can result in a serious violation of your privacy. After a successful breach, cybercriminals can record your most private moments and release them online. They can also demand money for destroying the recordings, which might not happen even if you cave in and pay the ransom.
Once installed, Pegasus can record video and audio, collect iPhone usage data and transmit it to hackers. Due to the overwhelming popularity of Pegasus among hackers and intelligence agencies, its developer collected $240 million in revenue in 2020 alone.
That study was published in 2013 and looked at MacBook and iMac models predating 2008, so you might be thinking that your Mac is safe from such intrusions, but as recently as June 2019 the threat of Mac web cams being hacked into caught the headlines.
Though slapping on a bit of tape onto your webcam is the most cost-effective way of preventing others from accessing your camera, if you want to avoid sticky tape residue on the lens, you could also go for a webcam cover. There are tonnes to choose from on Amazon and you can often buy them in packs of three or more.
Spyware: Here hackers attempt to gather sensitive data about you, such as your log in details. They might use key loggers to record what you type and eventually have the information they need to log in to your accounts. In one example, the OSX/OpinionSpy spyware was stealing data from infected Macs and selling it on the dark web.
Ransomware: Some criminals use Ransomware to try and extort money from you. In cases like KeRanger hackers could have encrypted files on Macs and then demand money to unencrypt them. Luckily Security researchers identified KeRanger before it started infecting Macs so it was addressed before it became a serious threat.
Once a hacker has access to your Mac there are various ways in which they might try to gain information about you, or use the processing power of your Mac for their own purposes. As we mentioned above, in the case of spyware the hacker might attempt install a keylogger so that it can record what you are typing and look out for your password. The hacker could also attempt to highjack your mic or video camera.
If you think your Mac has been hacked there are a few ways to find out. First of all look for the signs: Has your Mac slowed down? Is your web connection painfully slow? Do the ads you are seeing look a bit more dodgy than usual? Have you noticed anything strange on your bank statements?
If you've ever looked into your webcam lens and wondered if a hacker is looking back, it's more likely than you may think. Cybercriminals have multiple tools in their arsenal they can use to hack into your webcams.
So, how easy is it for someone to hack your webcam? In short, it's not incredibly easy. It's not like a hacker can locate and access your webcam without some aid. However, if a hacker gains a foothold on your PC or laptop, it should be a simple job for them to peer through your webcam at you.
There were claims that the feature was only used in cases of reported laptop theft. However, many students reported briefly seeing the webcam indicator light flicker on, causing some to tape over the camera.
A webcam that connects to another device over the internet is a convenient way to check up on your home while you're out. A lot of smart home security kits offer surveillance cameras you can access from anywhere to spot burglars. You can also turn a webcam into a home surveillance tool using special software.
If a hacker cannot use an existing entry point to your webcam, they can create one instead. This is the easiest method for hackers, as they don't need to look for victims; instead, the victims come to them.
That's why it's so important to download a dependable antivirus, keep it up to date, and give your PC a scan every so often. A good security suite will spot intrusions and protect you from a hacker's attack.
If you have a USB webcam, be sure to unplug it when you're not using it. No matter how good a hacker is, they can't look through your webcam if it's not physically plugged in. When it's time to show your face to the world, plug the webcam back in. Remember to unplug it again once you're done.
A hacker may be smart enough to breach your defenses and enable your webcam, but if something covers the lens, all that effort would be for naught. After all, even the best hackers can't see through tape without X-ray vision!
Is it easy to hack a webcam? Yes, if you give the hacker the tools they need to get into it. However, there are plenty of steps you can take to stop that from happening, and if all else fails, just cover it up!
Many people are seen to put strips of tape and other adhesive materials on their MacBook camera in an attempt to thwart any potential hacker from accessing their system and camera. MacBooks have a green "camera light" on the right side of the FaceTime camera on the front that seems to turn on when the camera is activated (i.e. the sensor is provided energy and transmits a signal to the motherboard).
Does the camera of a modern MacBook require that the green camera light turns on as well? In other words, is the camera light hardwired to the camera in such a way that if the camera is supplied electricity, that itself would enable the camera light? This would prevent a hacker from being able to obtain any information from the camera without the user being notified by the green light.
The original cameras had the problem that the JHU researchers detailed in the article that your linked to. Problem was that the firmware was downloaded on every boot and there was no security/encryption mechanism for verifying it. The part used was fairly common and the firmware was just in RAM (hence the loading after a cold boot), as oppose to flashed.
On some laptops the indicator light can be hacked and turned off. However, as a reader has pointed out to me, Apple has a physical method to ensure the light can not be disabled. It is wired in series with the camera so if you turn off the light, power no longer goes to the camera.
The FaceTime HD camera built into your Mac computer is designed with your privacy in mind and uses a camera indicator light that glows green when the camera is active. So you will always know when the camera is on.
Student Ryan Pickren, who previously discovered an iPhone and Mac camera vulnerability, said the new webcam vulnerability concerned a series of issues with Safari and iCloud. The flaws, now patched by Apple, could let malicious websites launch attacks.
Pickren further explained the problem would give an attacker full access to all web-based accounts, including big services like Gmail, iCloud and PayPal. It also would enable permission to use the microphone, camera and screen-sharing. Use of the camera might not go undiscovered, though, because the green indicator light would show as usual.
Today's electronic devices such as desktop computers, laptop computers, smartphones, and tablet computers are often provided with cameras. Electronic devices with cameras can include an indicator light to indicate when the camera is recording, to alert the user and/or others in the vicinity of the camera that they may be being recorded. However, conventional devices having cameras and indicator lights can be vulnerable to tampering to disable the indicator light, which can expose the user or others to being recorded without notification.
Apple's invention covers systems, devices, and methods for prevention of masking, disabling, destroying, and/or otherwise tampering with a visual indicator that a camera is recording or otherwise capturing images or other information. In one or more implementations, a light sensor is provided in close proximity to a visual indicator (e.g., a light source such as a light-emitting diode (LED) configured as an indicator light for the camera) and coupled to the camera, such that insufficient light received by the light sensor disables the camera. In this way, if the indicator light is covered, masked, or damaged (e.g., in an attempt to allow the camera to record and/or capture other information such as images, sound, depth or other information without an indication of recording by the indicator light), the light sensor resultantly disables operation of the camera. 2ff7e9595c
