FBI Mac OS X Safari ransomware
For years, Windows users have been plagued by ransomware demanding several hundred dollars to unlock their computers.
The bad guys know there is a growing market of Apple consumers who, for the most part, feel pretty safe about browsing the Internet on a Mac without the need for any security product.
Cyber-criminals, well known for not re-inventing the wheel, have ‘ported’ the latest ransomware to OS X, not by using some complicated exploit but rather leveraging the browser and its ‘restore from crash’ feature.
The FBI Mac OS X ransomware page is being pushed onto unsuspecting users browsing regular sites but in particular when searching for popular keywords.

The FBI Mac OS X MoneyPak virus will display a bogus notification that pretends to be from the Federal Bureau of Investigation, and states that your computer has been blocked due to it being involved with the distribution of pornographic material, SPAM and copyrighted content.

The FBI Mac OS X virus will hijack your Safari browser, so whenever you’ll open this program, it will display instead a lock screen asking you to pay a non-existing fine of  $300 in the form of a MoneyPak voucher.
A quick look at the address bar shows an interesting URL: fbi.gov.id657546456-3999456674.k8381 . com, the bad guys are clearly trying to fool users.

Furthermore, to make this alert seem more authentic, this virus also has the ability to access your installed webcam, so that the bogus FBI Mac OS X notification shows what is happening in the room.

If your computer is infected with the FBI Mac OS X MoneyPak virus, then you will see the following Safari web page:

The message displayed by the threat can be localized depending on the user’s location, with text written in the appropriate language.
