Is it possible for someone to bruteforce or perform a dictionary attack on a Macbook?

It's very easy to bypass security of a Windows box (Password Protection) , what is the difficulty level of bypassing the security of a mac running OSX.

Can someone run forensics on it and recover data without knowing the password?

  • Sure, a weak sudo password should necer be chosen. Without complete encryption reading the data is no big problem for IT forensics. – Daniel Ruf Nov 29 '15 at 16:52
  • the question is that how they can go about brute forcing a password on a locked macbook. @DanielRuf – Sanidhay Nov 29 '15 at 17:00
  • What do you mean with locked? You did not mention this. – Daniel Ruf Nov 29 '15 at 17:03

    Brute force what? What is the state of the computer? Can the drive be removed or duplicated? Is there drive encryption? Is the computer locked? – Neil Smithline Nov 29 '15 at 21:53

    Ask a single, clear question. If you have multiple questions, post them separately. – Alain O'Dea Nov 29 '15 at 23:24

Sure, John the Ripper for example and other tools can crack the passwords.

Always choose a secure and random password.

Bruteforcing applies to any OS.

You can encrypt partitions and complete disks.

Without any secure encryption anyone can read the data from the disk with the right tools. There are great opensource IT forensic tools available.

There are also known bruteforce attacks on the EFI PIN and iCloud lock used for locking the device.

    IMO, the question is way too unclear to warrant any kind of an answer at this point in time. – Neil Smithline Nov 29 '15 at 21:51
  • Well "Can someone run forensics on it and recover data without knowing the password?" Theoretically yes, it is possible. – Daniel Ruf Nov 29 '15 at 22:26
