Remove “Your browser has been locked” virus from Apple Mac OS X

If your Apple Mac OS X browser is locked, and you are seeing a “Your browser has been blocked ” notification from the Federal Bureau of Investigation, Australian Federal Police or any other law enforcement agency, then your Safari web browser has been hijacked.
[Image: Your browser has been locked FBI MAC OS X]
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 “Your browser has been locked” ransomware page is being pushed onto unsuspecting users browsing regular sites but in particular when searching for popular keywords.

The “Your browser has been locked” 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 “Your browser has been locked” 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.
If you choose to ignore the message “Your browser has been locked” Mac OS X, you cannot get rid of the page, as you will see this notification:

Your web browser has been locked.
All PC data will be detained and criminal procedures will be initiated against you if the fine will not be paid.

Furthermore, to make this alert seem more authentic, this virus also has the ability to access your installed webcam, so that the bogus “Your browser has been locked” notification shows what is happening in the room.

If your computer is infected with the “Your browser has been locked” 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.

    I just minimized the page so I could access task manager and closed my browser from there(applications)..no biggy..but I wasn’t surfing for porn at the time.i was googling to find out what the most popular music is that teens were listening to in other countries and in europe.i guess the word teens attracted the scam page? or the combination of words I used.i don’t remember now exactly how I worded the inquiry.yeah,the site claimed that I’ve been charged with the crime of downloading child porn,etc..had my ip number,city,etc..that’s so easy to do it’s unreal..my personal web page collects much more than that from visitirs via a software called tracemyip.that kind of program is common and usually free to download or to use.i pretty well knew what was going on when the thing popped up.i figured since I have the pay version of avast and it didn’t alert me that it wasn’t anything but javascript scam.so I clicked to minimize the page (couldn’t access task manager otherwise) and from “applications” I closed the browser(IE in my case)..I love challenges.

    My computer had this problem I just force quite Google Chrome is that ok? Will they still go after you after the range of 24hours to 72hours if you don’t pay? I don’t know because I’m scared what should I do if it actually locks?

    • http://malwaretips.com/ Stelian Pilici

      Hello,
      This infection is nothing more than a javascript on a web page, so it does not drop any files on your machine.
      It will NOT lock down your machine or encrypt your files, you just need to follow the steps from this guide, and that’s it!
      DO NOT SEND ANY KIND OF MONEY TO THESE CYBER CRIMINALS!

      stay safe!

  • PrincessPond

    Hello,
    No, you should be fine as long as you don’t see that malicious javascript page. :)

  • Halo

    You should really add that there is a Norton Antivirus scan Mac users can perform. The scan is free to download on the App store on your computer. Just search for it. I’d double check with that after all this, just to reassure everything is secure.

  • Confused and Nervous

    For some reason I got a porn pop-up. After that I got an F.B.I. pop-up saying I was in violation of watching child porn. I was confused, but it didn’t lock. Was it because I was on Chrome, or something else. I could close the pop-ups and nothing happened. Should I worry?

      Hello,

    • http://malwaretips.com/ Stelian Pilici

      Hello,
      Yes, cyber criminals are always chancing the design of this lock screen however the scam works the same.
      Your browser gets “locked”, and you are asked to pay a $300 fine, for some fake reasons……

      Stay safe!

  • http://malwaretips.com/ Stelian Pilici

    Hello,
    Lets try these steps:
    1.Click on Safari in your browser menu, located at the top of your screen. When the drop-down menu appears, select the choice labeled Preferences…

    Please note that you can use the following keyboard shortcut in lieu of the aforementioned menu item: COMMAND (APPLE) + COMMA

    2. Safari’s Preferences dialog should now be displayed, overlaying your browser window. Click on the tab labeled Security.

    3.Safari 5′s Security Preferences should now be displayed. In the third section from the top, labeled Web content, is an option titled Enable JavaScript. By default, this option is checked and therefore active. To disable JavaScript, simply uncheck the appropriate box.

    Close your browser, then open it again. Go to google.com, then you can re-enable the JavaScript option.

    Stay safe!

    the ‘reset’ option was blocked for me too, so I forced quit Safari, turned off my wifi, reopened Safari, closed the tabs, and then reset Safari.
    SHould we delete any other files on our computers that the malware may have installed?

      Hello,

  • JEDee

    MAC + FireFox
    I had this malware on my MAC while using FireFox. The only way to close FireFox was with key combo Cmd+Opt+Esc. Force Quit FireFox. Then when I reloaded the page, I closed the pop up window before it could load. Finally, I deleted all the history. It seems to be working fine now. Do I need to check anywhere else for this Malware to be hidden? Thanks for your help.

      • Edward the King

        I just tried this for Firefox, and it worked! Thank you so much!

      • Stupid Guy

        That worked

  • http://malwaretips.com/ Stelian Pilici

    Hello,
    Did you uninstall Safari? Or what software?
    There are not malicious files on your MAC, so you can calm yourself down. :)
    This infection is leveraging the browser and its ‘restore from crash’ feature, basically it has “sticked” that page on your Chrome, however there should not be malicious files on your computer. So resting the browser settings is enough to remove this ransoware.
    Stay safe!

  • Jd82990

    Holy crap. My heart sank into my stomach when I got this message. I was wtf!? Are you serious? It happened on my Mac when I was browsing tumblr and was being redirected to another site. However, I was able to click out of before the page fully loaded and nothing happened. I rebooted just to be safe and everything is working just fine now.

    I almost had a heart attack when I saw this just a minute ago. I ended up turning off my computer because I didn’t know what else to do and lo and behold it went away. Also, it was the right thing to do apparently. When I got back in I thought, ‘That must have been fake’. I looked it up and my search brought me here. So glad it’s not an actual fine. I literally had a panic attack though.

  • Lance

    Thank you!

  • Ra

    Gotta love mac Reset worked many thanks. Mac is hardware they cant reach that windows is open and the software is way to open . Bless you .

  • Adam

    force quitted Safari and re-booted, did the trick

  • Whats the frequency Kenneth

    They made a very created web page that had an endless loop of “locked” messages. I was surfing pr0n, and got this message instead of the usual site referral BS. I was using “private browsing,” as always, when surfing pr0n, so all I did was force-quit the Safari. I was still curious, though, so I looked it up and found your post. Thanks for the info. Yet another failed OS X exploit!

    • Michael P. McCracken

      I downloaded the source code and all associated files for this piece of junk when it showed up in Firefox on my Mini. There are 154 repeat instances of the “Are you sure you want to leave this page?” javascript. Just for sh!ts & giggles I ran it again and it went through ALL 154 warnings, before the page finally closed on its own.
      This IS NOT a virus, but a very deep set of javascripting, counting on most people to “give up” before they reach the end of it.
      My brother got hit with the REAL FBI ransomware virus on his PC. It’s a nasty one, a “rootkit” that launches the browser with the hijacked message BEFORE the user can even get to their desktop. It disables keyboard commands to get out of it (like Alt+F4 or Ctrl+Alt+Del) and entering a MoneyPak code DOESN’T remove it. We did the ONLY thing a PC user can… Reformat and reinstall Windows.
      I’ve tried for years now to get my brother to switch to Mac and I really thought this experience (he nearly lost four years of business records – thankfully the virus DIDN’T affect his external drive) would finally do it. He just bought an HP laptop with Windows 8
