Macs are not based on Linux in any way. MacOS is a true, certified UNIX (check with The Open Group to verify certifications) that is based on FreeBSD, NetNSD and OpenBSD. It is possible to hack into a Mac. If you have physical access to the Mac then it is possible to hack into it. If you can persuade someone to download a script that will give you access to the Mac.

If you’re thinking hackers did not hack your computer machine because you’re a small fly nobody wants to hack you. That’s your biggest mistake hackers always try to increase IP database through hacking computer.

When hackers, hack any website or server they generally do it by opening that particular site to millions of IP address and hence the server in cash. So you’ve to check if you’re being targeted by the hacker or if on your mac there is any backdoor from which you’re monitored.

If you questioning your self “How to tell If your mac has been remotely accessed” by hackers. If you’ve felt your computer has been hacked you can easily check it and prevent using simple tools and software such as installing anti-virus on your Mac.

The answer is simple, there some ways from which you can easily determine your computer is hacked.

Must Watch This Video To Know Why Your Mac Has Been Hack

1 # Can I Tell If My Mac Has Been Hacked

To determine if your mac has been already hacked by hackers you have to know if things. First of all, you've to spot some sign of possible hacking.

You'll have to consider whether anything out of the usual is happening on your notebook. You know how your computer runs better than anyone else. If you've noticed anything usual after starting your MacBook. The weird sign includes.

• When you try to open any file but it won't open.
• Any Program automatically starts without running it.
• You cannot access any file or program protected by password setup by you.
• When you're not using your computer but still sometimes its connect to the internet automatically.
• File contents have been changed but your not who change them
• Your Printer not working but all look fine.
• The wired warring message shows up on the screen.
• Go online and check your online account passwords.

There are lots of signs from which you can easily detect your computer is hacked by somebody or there is a backdoor on your computer which remotely accessed by the hacker.

2 # Go online to check your Online Accounts through Private Browser

When you try to login into your online account such as Email Account you see a password failure. If you're feeling you're already hacked then, in this case, check your online account using a private browser. Because private browsing is safe and secure.

You can also notice if your network connection is redirected to another IP address or computer. Lots of small hackers try to hack network to enjoy free internet but they can also remotely control your computer.

When you're browsing through the web browser you may also see an extra browser open up automatically without doing anything. If you own a domain for your website or blog you can access it after getting hacked.

3 # Anti-Virus Stop Working When Mac Computer Has Been Hacked

In Mac, if you already installed an anti-virus then this the best thing you've done to secure notebook. To find out if your mac address has been hacked. You can easily check it out by scanning your Mac.

Usually, Mac users have to scan its system regularly to know if check anything usual such as the trojan virus. Trojan Virus is the virus created by hackers these viri contain backdoor or the spirits and command lines to open hidden gateways on your computer.

If you notice lots of trojan virus on your computer on the regular scan it is also a sign that your mac has been hacked.

4 # Check All Accounts Created By You on Mac Using Command Line

If you're thinking how would I know if my mac has been hacked into. Have you notice someone has seen your information and conversation on your computer. According to hackers, it is easier to hack mac in comparison to PC.

There are lots of mac terminal hack commands with the help of which hackers entered into your computer. But you can also use a command line to determine whether your Mac has been used without your authorization.

Step 1:

Login into your Mac OS notebook using for the regular account

Step 2:

Click on Applications > Utilities > Terminal

Step 3:

In Terminal (Command Prompt). Enter this command line 'sudo -l'.

Step 4:

Press Enter and then type account password and again press Enter.

Step 5:

Again in Terminal type following command line to open up the complete list of all accounts created on your Mac.

dscl . list /users

Step 6:

Press the 'Enter' button

Now you can easily check a complete list of account on your Mac OS computer. Check whether any account is created on Mac without your permission. If your mac is hacked there are additional accounts created by hackers.

Step 7:

In this last step, check whether an account is misused by any hacker. Type gave the following command line on Terminal

last

Hit 'Enter' now you can see each account on Mac last login date and time. Check out if there is an account which recently login without your permission.

“No security is better than lame security” – Ray Biez circa 1998

Apple, for all their self-congratulatory PR that fills mainstream media, is privately (in)famous for, well, piss-poor security. It’s harder to remove the OS password from a Windows PC – even one running XP – than it is to do the same on even the latest Mac/MacBook. Ok, it’s not exactly rocket science to remove the user security from either, but you do need more than just your fingers to bust the Windows security.

iCloud is Apple’s offering to secure users hardware in case of loss/theft, a multi-faceted product that covers hardware running both Apple operating systems – OSX and iOS. Although it’s a highly vaunted product, they’ve taken a long time to perfect the iOS version – previous to iOS 7.1.1 it’s not too hard to break that thing off. (Using only your fingers.)

And the OSX version, oh boy.
That’s like a combination lock there, takes 4 digits to unlock it. So let me work this out – 0000 is the lowest possible code, while 9999 is the highest. And if it’s not either of those two, then somewhere in between is your answer. A rather trivial total of just 10,000 possible combinations. Given enough time & patience, this can even be done manually – eventually you’ll type the correct sequence.

Fuck that, manually typing 100 combinations would piss me off. I know, let’s use science & technology! The micro-controller industry has given us a bunch of tiny component-style silicon boards, capable of just a specific task or two. Teensy 3.1 is an Arduino-like board that can be programmed to emulate a USB keyboard & mouse. Here’s the one I received today:
Plug it in via micro-USB – see the glowing light, it lives!

So, hunt down a Teensy 3.1 via your local Googles. Mine was delivered overnight for $NZ41 incl postage. Download and install the Arduino & the TeensyDuino SDK software, which includes the two required libraries – USB_keyboard.h & USB_mouse.h. Copy these two files to a project folder, to where you’ll add the magic code before compiling. The SDK is available in OSX, Windows & Linux variants.

Next you need to either write the code from scratch or source pre-compiled code that’ll do the consecutive number entry we require (with some additional variation in the routine to circumvent Apple’s minor multiple entry time lock defence.)

You’ll find two proven choices, Orvtech and Knoy. I’ve used both, right now – at this very minute in fact, Knoy’s version for the 15″ MacBook Pro is chugging away next to me. I’m not so sure about the Knoy codebase, but since it’s a 5 minute procedure to reprogram the Teensy, the Orvtech code can run on the MacBook Pro if there’s no result from the Knoy compile. The Knoy code runs quicker as it invokes restarts more often than the Orvtech solution. Having said that, Orvtech worked for me last time.

UPDATE: I don’t know why but the Knoy Arduino solution failed. I gave it two machines to play with, parked them in a cupboard & left them alone for 2-3 days each. Both times I returned to find a dark screen, pre-booting the lock screen with the Teensy 3 flashing fast & bright.

So I’ve re-coded with an enhanced version of the Orvtech script –

Running this code against the iCloud block (iCloud lock is an overstatement) is a simple process. Plug yer Teensy in, boot the Mac, kick back & wait. It takes about 17 seconds per entry, averaged, including restarts to circumvent the multiple-entry hurdle. Time til breakthrough is dependent upon where in the range the code is, but expect the tell-tale “dong” success tone within 72 hours. But hey, if the iCloud code was set at a low number, say 0XXX, then hang around for an hour or so cos your answer is on its’ way.

iCloud cracker in action

The practicalities of this code are not extensive. It’s more an application in slow, methodical cracking than any brilliant invocation of a hi-tech algorithm. There is no salted hash to track down and crack, it’s just a simple exercise in orderly, automated data entry (that a patient human can also do. Or a monkey, a well-trained monkey.)

There aren’t, seemingly, that many Mac computers utilising iCloud protection. I think it’s a far better idea to keep your Apple product out of harms way, locked down & tucked away safely. That, and insured. Keep your Mac backed up (data insurance) and commercially insured.

UPDATE: I got sick of wait, wait, waiting for the Orvtech solution to show me the money. I can’t do unoptimised code, I just can’t. Digital is a direct thing, the shortest way between two points. So why sit round waiting for 15mins when a restart takes less than 2mins?

While I was waiting for the inefficient code to bumble its way through, I took a fresh look @ the Knoy compile – his code is offered for 15″ or 13″ MacBooks – made some minor adjustments of my own then rebuilt the Teensy & set it loose on a 2011 15″ MacBook Pro again.

Three days in, somewhere past the 5000 mark the reboot chime halted – cracked it! To make sure it wasn’t a fluke, I immediately put a second MacBook Pro, same spec, up against the Teensy. Around 18 hours later, Ka-ching! Cracked it!

PS: Do not even think that your bright idea of reformatting the hard drive on an iCloud locked Mac will solve the puzzle far quicker than the system described above. It won’t. What it will do is increase the EFI lock code from 4 digits to 6, taking the cracking process from 3 days to around 7.5 months. Your best advice, if you are less than fully aware of Apple security, is to Step Away From The Keyboard – pay somebody who knows what they’re up to.
