Do you think that your Mac was hacked? Do you feel that someone or something is spying on you when you are watching YouTube, or when your Mac is left unattended at home?
3 hours ago Five Mac Apps Worth Checking Out - July 2020. Each month, we share a video highlighting a handful of Mac apps worth checking out. This month's selections focus on.
There are many ways how a human or a program can get on your computer and do harm to you and your privacy:
- It could be a spyware, a malicious hacker, or someone you know, such as a parent, a spouse, a friend.
- They can access your photos, videos, and emails
- They can take embarrassing pictures of you using a webcam
- They can listen and record your conversations
- They can monitor your browsing history
- They can use your computer to mine Bitcoins
- They can encrypt everything on your disk and then ask for a ransom
Computers have never been safe, and now when we rely so much on them, it is extremely important to protect ourselves from malicious actors.
This topic is too broad to fit into one blog post, so I am writing mini-series, which will help you to minimize the impact and secure your Mac.
Signs That Your Mac Was hacked
If you are reading this post, chances are you noticed something unusual is happening on your Mac. Sometimes you have a hunch, but you can’t explain it. However, most of those signs can be explained by reasons other than malware or hackers. So, let’s review the major signs.
Mac suddenly became slow for no apparent reasons
I’ve been developing commercial software for more than twenty years. There were many times when I received a call from the customer complaining that their computers, servers, programs are slow.
Every time I am getting a call, the first thing I ask if they did something before they noticed the problem. Do you know how many times they admitted that they changed something? You guessed it, zero. How many times did customers cause the problem? Almost always.
Following are some of the reasons why Mac can be slow:
- There is a virus or other malware
- Not enough disk space on Mac
- New OS was installed
- Hardware failure
Mac is using more Internet than usual
This one is harder to detect now than before. We used to have limits on how much Internet bandwidth we could use. Today, when many people have unlimited data with cable, you may not even know that something is happening.
However, if you are on a limited plan, and you see a significant increase in data consumption (more than 25% more), it’s time to investigate.
The reasons could be the following:
- Your Mac is being used as a bot by hackers
- There is a virus or other malware
- Your little one grew up and now watching YouTube all day on your computer
- New OS was installed
- Youtube and other web sites are taking forever to load
Similar to the previous sign, problems with the Internet could be a sign pointing to a virus or adware affecting the browser. Or it could be a new browser update. Or maybe the system became unstable.
Programs crashing more often
Did you notice that apps getting stuck and eventually crashing? Very often, it’s a sign of malware. Additional reasons for frequent app crashes are the following:
- Lack of memory (RAM)
- Lack of disk space
- Temporary system instability
- Hardware failure
- Unusual pop-ups in the browser
This is something we all have seen. You download an app from the Internet and seems like it was a legit software. But little did you know a good app was bundled with bloatware.
Usually, the result is that your default search engine gets changed from Google to Yahoo, the home page changes, and there are additional icons in the browser toolbar. But there could be other issues such as adware.
Adware is trying to redirect you to other sites, not related to what are you searching for. Their goal is direct traffic to certain sites. More traffic, more money they get. So, they litter your screen with pop-up, hoping that you can click and open the site you don’t want.
New files appear or old files disappear
Malware often creates new files with cryptic names. For instance, ransomware encrypts the files on your disk and renames them. However, there could be more innocent explanations.
For instance, if you can’t find a file, it does not necessarily mean that it was deleted by malware or someone who logged in on your computer remotely. Maybe, you just can’t remember that you deleted the file or the folder. In this case, first, check Trash on Mac.
If you still can’t find what you need, check my post about finding any files. I guarantee, if the file is still on your Mac after reading my post, you will be able to locate it.
How To Tell If Mac Was Hacked
First, scan your Mac with an antimalware solution. Next, turn off remote desktop and screen sharing features to make sure that nobody can connect to your Mac remotely. Verify that there are no keyloggers. Finally, eliminate reasons unrelated to hacking: reboot Mac, perform NVRAM/PRAM reset, check if there is enough space on the startup disk. If possible, visit the Apple Genius Bar for advice.
Now, let’s go over all the above in detail.
Scan Mac for viruses
I recently called Apple Support and complained about the slowness of my MacBook Pro. I could’ve solved the problem myself, but I just wanted how much would it cost for Apple to perform diagnostics on a 5-year old MacBook.
Since I don’t have AppleCare for my Mac, I thought that they would charge me something. Spoiler alert: I wasn’t charged for anything.
So, when I called, the first thing the Apple advisor made me do is to install the Malwarebytes app.
While Malwarebytes is a solid recommendation for scanning, it is not the best. In fact, I stopped recommending it to any Mac user after the test I performed myself recently.
I tested a dozen of antimalware product and only one detected 100% of 117 malware samples I intentionally downloaded on my MacBook. So, if you need a recommendation on a good antivirus check it here.
Tighten up access to your Mac
Programs are not the only threat out there. People sometimes can be even more harmful. There are several ways for someone to spy after you.
One is via remote desktop. Maybe you had experience connecting to servers or other Windows machines at work by remote desktop connection. Macs, even MacBooks, also allow such connections.
Also, it is possible to share the screen of your laptop. While it’s a useful feature, if you mean it, it’s not so good if someone’s using it when you are not aware.
And finally, since macOS has UNIX roots, as any UNIX like the operating system, it can be controlled via SSH protocol. Anyone with access can do pretty much anything on your Mac, and you wouldn’t even know.
If all of the above sounds complicated, don’t worry. I wrote a very detailed post on a topic of remote access to your Mac (https://macmyths.com/how-to-tell-if-someone-is-remotely-accessing-your-mac/). All you need is to go over the post and follow the simple steps outlined there.
Mac keyloggers
For a long time, I thought that all keyloggers could do to record keyboard strokes. Imagine my shock when I started working on my post about keyloggers.
Did you know that a new generation of keyloggers can do screenshots every 5 seconds, or record your messages and social media chats? And they can upload the collected information to the cloud.
And the worst part they are freely available for anyone to purchase!
To find out how one can identify a keylogger on Mac I installed 5 most popular apps on my laptop. They completely trashed my system, but luckily I had backups, so I was able to recover my MacBook.
Things to try if no virus found
While you are maybe suspecting something bad happening on your computer, it very well may be a normal condition.
Things to try before starting panicking:
Reboot
Sometimes glitches in software can make the current state of your system unstable. A reboot is still a remedy for many problems. You can either restart or shutdown and start again. The effect will be the same.
NVRAM/PRAM reset
Macs historically have a little memory cell where they store some information needed for many Mac peripherals to work. Surprisingly, this area gets corrupt pretty often. Fortunately, there is a very simple fix – reset NVRAM/PRAM and SMC.
Hacker password facebook free download - MSN Password Hacker, Wifi Hacker, Facebook Password Recovery Master, and many more programs. May 29, 2019 Facebook Password Hacker on PC (Windows / MAC). Download and install Android Emulator for PC of your choice from the list we provided. Open the installed Emulator and open the Google Play Store in it.

Under the intimidating circumstance that you or maybe your friends have been the victim of a Facebook hack make sure to replace the password immediately. Modify the password for your e-mail as well so that the intruder is unable to recover the password. By doing so you will have the hacker shut out of the profile and once more you will be.
Apple has very good instructions on how to perform these tasks.
What they don’t tell is that you have to reset at 2-3 times in a row for a fix to work. I found out this in the school of hard knocks so that you don’t need to.
Clear some space on disk
Lack of space on your startup disk may cause all kinds of issues: app slowdown, app crashes, high CPU usage, and MacBook overheating. Sometimes this may lead you to suspect that your Mac was hacked.
So, first, check how much storage you have left. And if it is not enough, you can either spend money on getting software that helps to clean your disk or read my article on free cleaning tips: How Do I Free Up Disk Space On My Mac Without Software.
New operating system
Apple releases a new version of macOS every year. While they do everything they can to produce quality software, bugs still happen.
For instance, after the recent iOS update on my iPhone, my podcast app starts freezing every time I pause. I still didn’t find why it is happening because I am too lazy busy.
In the case of the issue on hand, if you had a recent OS update, take time to investigate if the issues you are noticing are common for the release.
Check for hardware failure
Macs are very dependable, and they can serve for many years. However, any hardware gradually fails. For example, a failing disk causes unexplained app crashes. Failed RAM will prevent the computer from starting.
There is a good article on the Apple web site about running hardware diagnostics. Try and see what it will report.
Visit Apple Genius Bar
If you have an Apple store nearby, definitely check them out. On several occasions, I had to contact them, they helped me for free. If there is a fee for diagnostics, they should tell you upfront, so you can decide if it’s worth it for you or not.
5 Things To Do If Your Mac Was Hacked
So, you did everything I told you, and you found out that either someone spying or if there was malware on your Mac. There are several things you have to do immediately.
Change passwords
I know it could be painful to change all passwords. I have accounts on hundreds of web sites, and there is no way I could remember all of them. Well, this is not what I am suggesting.
You have to change passwords on the most important sites:
- Your primary email account. The one that is linked to your bank accounts.
- Bank and credit card accounts
- Work email password
- Apple ID and iCloud passwords (note, they are not the same)
If you are using one password for all sites, consider using 1Password utility.
Check bank statements
It never hurts to go over your bank statements (if you have any) once a while. If you notice some suspicious activity, then do a little research. But don’t panic right away if you don’t recognize a charge.
Almost every once, when I check my credit card statements, I see one or more charges which I don’t remember doing. However, after 5 minutes or so, I remember what it was.
Check credit report
Everyone in the U.S. has a right to get a free credit report once a year. Since there are three main agencies, you can get a free report three times a year (one from each agency). Search for “Annual Credit Report” in Google, but be careful to skip some ads and use the legit site.
Turn on Two-Factor Authentication
If you didn’t do this yet, turn on two-factor authentication on main sites: email, any money sites, etc. It’s a little bit inconvenient, but it’s the best way to prevent hackers from stealing your data.
What’s Next?
I hope I gave you some high-level information you needed in case if you think that your computer was hacked. Now, I suggest to check the articles I mentioned above in the following order, so you know how to deal with the problems outlined:

1. Your gadget suddenly slows down
Write from memory app machine. One of the side-effects of malicious software is a slow gadget. Software gets sluggish, or constantly freezes, or even crashes. If you start noticing some of these symptoms, your gadget may very well be infected with viruses, trojans or worms.
Malicious software usually runs in the background, secretly eating up your gadget's resources while it's active.
Here are tools you can use to pinpoint those nasty applications. If an application that you don't recognize is hogging your computer resources, it's likely a virus.

PC: Use Task Manager
There are a few ways to see what processes your computer is running. The easiest is to bring up Windows' built-in Task Manager. Just use the keyboard shortcut CTRL + SHIFT + ESC and go to the Processes tab.
Put simply, the Task Manager lists all of your computer’s current tasks and how much processing power they’re using, measured in Central Processing Units (CPUs). Open up Task Manager and check the CPU and memory columns for each process.
You might find one process is using 100% — or close to it — of your CPU. Open up the program associated with the process and see what it's doing. Restart the task and monitor it, but this program might be the culprit.

Mac: Use Activity Monitor
The Mac equivalent to Task Manager is its built-in Activity Monitor. The quickest way to access the Activity Monitor is by using Spotlight Search.
Click the magnifying glass on the right side of the menu bar at the top of your screen, or press Command + Spacebar to open a Spotlight window and start typing the first few letters to auto-complete 'Activity Monitor.' Just press Enter to access the tool.
Similar to Window's Task Manager, Mac's Activity Monitor displays a list of all your open processes with tabs for CPU, Threads, Idle Wake Ups and Network usage.
Learn these three troubleshooting Mac shortcuts the pros use.
If this happens when you are on an iPhone, try a soft reset by holding the power and the home button until it reboots with the Apple logo. This step can clear out frozen apps that can be hogging your memory.
2. You’re using way more data than usual
Every Internet provider has tools that can keep track of your monthly bandwidth consumption. Look at Data Usage Meter or Data Monitor, depending on your provider. Compare the amount of data used from the prior months, and if you notice sudden spikes in your data activity even though you haven't changed your patterns, then chances are you are infected.
For example, adware infected gadgets usually perform unsolicited clicks in the background to generate profit for cybercriminals. These stealthy tactics use up bandwidth and the unauthorized data they consume should be fairly easy to spot.
Do you want to save on your data consumption? Here are 5 steps to cut your data usage in half.

3. Videos suddenly buffer and web pages take forever to load
When a streaming video suddenly freezes, and your device appears to be “thinking,” this is called buffering. This annoyance often happens, especially if you play a lot of videos or your Wi-Fi connection is weak. If it’s happening a lot, or videos fail to play at all, you’re wise to suspect neighbors are piggy-backing on your connection. Click here for steps on how to check for Wi-Fi thieves.
Then again, malware can also slow down your Internet traffic by DNS hijacking. In short, hackers can redirect your Internet traffic to unsafe servers instead of the secure servers. This will not only slow down your browsing experience, it's also a serious security risk. For example, if your router's DNS settings have been hijacked, each time you visit your online bank's website, you'll be redirected to a phishing website instead.
To check your router's DNS settings, you can use an online tool like F-Secure Router. For more security, consider changing your DNS server to one with advanced hijacking protection like CloudFlare or Quad9.

4. Programs and apps start crashing
Now, here is a clear sign that your system has been infected. If your antivirus software and task manager are either crashing or disabled, a nasty virus has likely taken hold of your critical system files.
You may not be able to click on once-reliable apps. In the worst case scenario, ransomware may prevent you from opening favorite files.
You can try and fix the problem by booting your gadget in Safe Mode. With Safe Mode, your computer will be running with just the bare essentials. This way, you can safely delete and uninstall any programs and files that you can't during normal operation.
Windows:
On Windows, search for System Configuration then open it >> select Boot tab then tick off Safe Boot >>check Minimal (this is enough for most cases) >> click on OK to confirm >> Restart your computer.

5. You start seeing pop-up ads
Malware can also add bookmarks that you don't want, website shortcuts to your home screen that you didn't create, and spammy messages that entice you to click through. Apart from slowing down your gadget and eating away at your data, these intrusive notifications can also install more malware on your system.
Criminals can also use DNS hijacking to modify the ads that you see while browsing. Instead of the regular ads that you should be getting, they can be replaced with inappropriate or malicious ones.
On Windows, clean out adware with SpyBot Search & Destroy. On a Mac, use Malwarebytes for Mac.
6. Your gadget suddenly restarts
Automatic restarts are part of normal computer life. Software updates and new application installs can prompt you to reboot your computer. Your system will warn you when these happen, and you can delay or postpone them.
Yet sudden restarts are a different story. With Windows 10, there's a free malware detection and extraction program called Microsoft Windows Malicious Software Removal Tool.
I recommend a Full Scan with this tool to verify that your computer is updated with the latest malware definitions.
