This tutorial covers various techniques and tricks you should be aware of if you’re concerned about someone remotely accessing your Mac.
What is Remote Access, and How is it Configured on MacBooks?
Remote access is the ability to use a different device to connect to a computer at any time and from any location. Through remote access software that someone may have set up on your computer, it is possible.
Be aware that remote access gives you the freedom to access and utilise files and programmes on a different computer from your own.
There are various ways to remotely access a computer via another device, depending on the operating system.
You must enable screen sharing, allow remote logins from another machine, or use Remote Desktop in order to access macOS remotely. Here’s how to control these parameters on your Mac if you don’t know how to:
Remote MacOS login
Keep in mind that if another machine is running macOS, it can connect to your Mac using Secure Shell (SSH). You must carry out the following actions in order to disable the remote login feature:
- In the upper-left corner of your screen, click the Apple icon.
- After the drop-down menu opens, click on System Preferences by scrolling down.
- Double-click the Sharing folder after finding it.
- The Remote Login checkbox must be unchecked.
- Nobody will be able to remotely use SSH to access your Mac once the Remote Login option has been disabled.
Mac screen access via screen sharing
One of the most popular methods for remotely accessing a computer is screen sharing. On macOS, follow these instructions to enable or disable this feature:
- Select Sharing by double-clicking in System Preferences.
- To enable or disable the screen sharing capability, locate the checkbox and click it.
- Additionally, you can choose whether to completely block remote access to your Mac via Screen Sharing or to selectively permit particular people.
Using a Remote Desktop for management
If the Remote Desktop capability in your macOS is turned on, another person can access your Mac remotely. It can be turned off by:
- Activate System Preferences.
- Double-click the Sharing folder after finding it.
- Uncheck the checkbox next to the Remote Management option once you’ve located it.
- Be aware that if your Mac has Remote Management turned on, Apple Remote Desktop can access it from a distance. Watch out for any overlapping rectangular images in the top right corner of your screen as well.
If it does, it signifies that someone is watching your computer. Fortunately, you may disable access to your Mac by selecting the Disconnect option.
How To Recognize A Hacked Mac
You might have been hacked if you’re wondering how to determine whether someone is remotely accessing your Mac. There are methods for determining whether it is being remotely accessed or hacked.
Keep in mind that the initial stages to determining whether your Mac has been hacked are to determine whether you enabled screen sharing and remote administration tools.
However, there are some more means by which you can confirm your worries. Here are a few warning indications that your Mac may be under attack.
Mac Became Slow Suddenly for No Known Causes
Your Mac is without a doubt one of the most powerful pieces of hardware on the market. There is a small risk that you will experience latency even if you are using an older version.
However, if your Mac seems to be operating slower than usual, that could be cause for concern.
Here are a few factors that could explain why your computer is running slowly:
Infections or Malware
The presence of a virus is one of the main causes that computer specialists link to a Mac that operates slowly. Threats from viruses or malware are common in today’s world, especially if your computer is always linked to the internet.
These programmes are made expressly to steal other users’ data without their knowledge and exploit it for illicit purposes.
Viruses and malware programmes are numerous, but they all function differently. They may also vary in terms of the threat they pose.
A virus can secretly access your computer’s files while hiding inside of it, sharing information with the hacker. For instance, dangerous software known as ransomware might prevent you from accessing your computer unless the specified sum is paid.
It’s crucial to remember that these malware applications might slow down your computer because they continue to run in the background. In the worst situations, they may corrupt your operating system files, slowing down or breaking your device.
Insufficient Disk Space
There isn’t much storage space on your Mac. Sometimes, you won’t even be aware that there isn’t much room left. Your Mac might operate more slowly if you don’t have enough storage. Usually, having a lot of data stored on your computer makes it challenging to access it right away. As a result, your Mac can take a couple of seconds longer than usual.
A Fresh OS was put in.
You may have installed an incompatible operating system, which is another factor that could cause your Mac to start acting abruptly slower. Not every operating system is designed to function with your Mac.
You won’t encounter any troubles if you utilise the most recent Mac hardware. However, the likelihood is that your older Mac may slow down as a result of shoddy hardware and incompatibility with the most recent OS.
Hardware Error
You can’t completely rule out the potential that the hardware in your computer will fail. As your computer ages, there’s a good chance that its hardware may break down and become less responsive.
Internet Use on Mac is Higher Than Normal
An additional indication that your Mac may be vulnerable to hacking is excessive internet bandwidth utilisation. It can be difficult to tell if your internet consumption has suddenly increased.
The availability of unlimited bandwidth by many Internet Service Providers makes it difficult to monitor internet bandwidth usage. If you use internet services with a metered bandwidth plan, however, a spike in data usage necessitates inquiry.
Before drawing any conclusions, you should consider the following factors:
Unsavory software
As was already established, viruses and other malware are the main culprits behind strange Mac problems. They are able to use your computer’s resources, such the internet, even though they could slow it down.
Once they get past your computer’s safeguards, viruses and other harmful software frequently connect to hackers.
They use your internet connection to accomplish this. As a result, if you observe an unusual rise in your internet bandwidth usage, a hacker may be utilising your Mac as a bot.
A number of Internet users
A frequent cause of increased internet bandwidth is an increase in connection usage. The increased internet consumption could be explained by the fact that your kids are spending the entire day watching YouTube on your Mac.
In any event, it’s important to remember that you must weigh all of these factors before making a decision.
Your Wi-Fi is Being Used by Someone Else
What could be funnier than getting free internet access? Your internet consumption may have increased unusually, which may be a sign that someone else is utilising your Wi-Fi.
Your neighbor’s kids may be using your internet since they discovered your Wi-Fi password. Another possibility is that a hacker got access to your Wi-Fi.
Other causes could be a fresh browser update or an unstable operating system.
Program Crash Rates Have Increased
Crashes in programmes can be annoying. But it also suggests internal problems with your computer, such as the possibility of a hack. It is cause for concern if you observe that your computer programmes crash and become stuck more frequently.
It typically happens if your Mac has been infected with malware. But a few additional factors also contribute to frequent app crashes. Below are a few of them:
Absence of Memory (RAM)
Aside from a malware assault, a computer’s memory or RAM shortage might cause a lot of software crashes. It’s possible that the app you’re using uses more RAM than your Mac can provide. Alternatively, RAM issues on your PC could occasionally result in app crashes.
Not Enough Disk Space
Insufficient disc space is another reason your computer programmes or apps could crash. For their functions, computer applications need a certain quantity of disc space.
However, if your Mac is short on storage space, it’s likely that the installed programmes may become stopped and eventually crash.
Unstable Operating systems
Your macOS may occasionally experience brief instability followed by app crashes. There are numerous justifications for why this occurs.
System instability can occasionally be brought on by underlying software problems. Or perhaps it’s because the hardware in your Mac isn’t working properly, which keeps crashing programmes.
Hardware Error
Hardware on your Mac and system stability are closely related. Numerous computer apps and programmes won’t function properly if your computer’s hardware is damaged or malfunctions in any way.
Adware One of the main causes of software crashes on your Mac is classified as adware. Adware, like malware, degrades the performance of your computer by diverting you to websites that you aren’t looking for.
Their goal is to send traffic to other websites so they can make more money. You might even notice that your Mac’s screen is overrun with pop-up advertisements, which causes software crashes.
Old Files Vanish or New Files Appear
Just be aware that malware and other harmful applications add new files to your computer’s hard drive if you have no idea how they function.
These files typically have obscure names that are frequently encrypted by the malware programme. For instance, ransomware renames and encrypts several files already existing on your computer.
You won’t be able to access those files until you pay the ransom demanded by the ransomware. However, the absence of a file does not necessarily indicate that malware or remote access are at blame.
It’s possible that you accidently erased the file and have forgotten about it. As a result, it’s always a good idea to examine the Trash file before making assumptions.
Take False Positives Out of the Consideration
Naturally, if your Mac runs slowly or your favourite programmes are crashing, you might start to worry. Your Mac may not actually be under hacker attack.
Sometimes, the hardware or software on your computer can malfunction, but you can quickly fix these problems. Here are some things you can try before you start to worry.
Restart the computer
You could occasionally have software issues if you use your computer frequently. When your system apps are not entirely optimised for the operating system, these hiccups or issues happen.
As a result, some apps perform improperly and may cause instability in your system. In these circumstances, restarting your computer can fix the underlying issue.
It makes no difference whether you choose to restart your computer or shut it down and turn it back on. Both possibilities are equally effective.
Reset NVRAM/PRAM
You might be shocked to learn that the hardware architecture of your Mac is intricate but effective. Many Apple consumers are unaware that a tiny memory chip contains tiny bits of crucial setting data.
You frequently need this information to make sure that your Mac’s accessories function properly. This memory chip, however, is constantly susceptible to corruption.
Fortunately, there is a quick remedy known as an NVRAM/PRAM reset if that little memory chip malfunctions. Be aware that for this fix to function, you will need to reset a minimum of 2-3 times consecutively.
Make Some Room on Your Disk.
Although it may not seem like a major concern, running out of space on your starting drive happens rather regularly. There is a considerable probability that your computer will have issues if your primary disc is full.
App crashes, sluggish systems, higher CPU utilisation, and overheating are a few of them. You can get certain your Mac has been hacked as a result of all these problems. Therefore, instead of freaking out, it is better to inspect your computer for low-storage issues.
A Fresh Operating system
A faulty computer may occasionally be caused by the installation of a new operating system. Operating systems of all kinds cannot be run on your Mac.
Your computer might not be compatible with it because each operating system functions differently. As a result, it can malfunction and cause problems.
Additionally, it’s not all good news if you update your Mac to the newest version of macOS. Although Apple annually releases a new, improved version of macOS, flaws do occasionally occur.
You can combat this by going to Apple’s official website and determining whether the problems you’re having are common with this operating system.
Examine Your Hardware For Issues
You can use your Mac for many years because it is a capable piece of hardware. However, because your hardware has a finite lifespan, it can stop working after lengthy use.
Therefore, you must run a hardware diagnostic to clear out any doubt about your Mac’s hacking.
Search For Keyloggers On Your Mac (Legal and Malware)
Powerful spyware known as keyloggers might jeopardise the information on your Mac. A keylogger, as the name implies, can secretly record the keyboard strokes you make.
Additionally, it can take screenshots and monitor your chat activities.
As a result, the majority of computer professionals consider keyloggers to be a serious security risk. The easiest strategy to combat keyloggers is to routinely run a full antivirus scan on your computer.
Check to See If Any New User Accounts Have Been Created
To remotely access another computer via Remote Desktop or screen sharing, local users need to have certain rights. Therefore, if you believe that your Mac has been hacked, the intruder most likely created and added a new user to obtain access.
Examining all of the user accounts that are present on your computer can allow you to quickly determine if your Mac has been hacked. If you come across any user profiles that you aren’t familiar with, a hacker may have made them.
To determine whether your Mac was hacked, you can also analyse login information and the timing of user profiles accessing it.
Check To See If Your WiFi Has Been Hacked.
The chance exists that the hackers may have accessed your Wi-Fi before getting into your computer.
Since your Wi-Fi router processes all data, it is simpler to obtain essential personal data like online transactions.
Check how many individuals are using your Wi-Fi; if there are more than you anticipated, a hacker may be involved.
Verify Which Mac Programs Have Access to the Camera and Microphone
Your Mac’s camera and microphone are two of the most popular entry points for hackers. If a hacker gains access to your Mac via FaceTime, they can record what you see on your camera.
The camera on your Mac is still hidden, but if it’s recording, you might see a green light next to it. The green light indicates that another app has accessed your camera or that it is being utilised for recording.
