“YOUR COMPUTER WAS LOCKED” Mac Scam – Distribution

There are two primary strategies that are used by the crooks to spread these types of scams across victim Macs. One of those is for the scammers to use compromised WordPress websites which have a sufficient user base. In those sites, the scammers may embed a JavaScript redirection, which is then used to cause a redirect each time you visit the compromised website. The redirect may infect your Mac with real malware, extract information from it by cookies, but it’s main goal is to show you the “YOUR COMPUTER WAS LOCKED” scam message.

But if you see other advertisements on your browser besides the “YOUR COMPUTER WAS LOCKED” notification, then the issue may be more serious than it is. The main reason for those advertisements may be a potentially unwanted program that is running actively on your Mac. These types of adware-infested apps often pretend to be free and helpful while they are advertised as “free extras” or “optional offers” via bundling, but be aware that they are classified as potentially unwanted, because they are indirectly harmful since they advertise URLs, like “YOUR COMPUTER WAS LOCKED”. These programs may often slither on your Mac unnoticed, because the come alongside the installers of other freeware apps downloaded from third-party sites, like your favorite web browser, torrent tracker or any other similar free app.

“YOUR COMPUTER WAS LOCKED” – Purpose and Activity

When your browser is hijacked by this tech support scam, the first thing that you will notice is it’s tech support scam note, which looks like the following:

The message also comes together with a pop-up that is difficult to close and has the following notification text:

The scam may also be accompanied by a voice message, that further scares victims that their Credit Card Data, Facebook and other important credentials are compromised and if the victim does not call the number provided in several minutes, their Mac may be shut down and locked by the “security experts”. All of these are scare tactics to get you as a victim to call the scammers and provide them with access to your Mac, which will result in the actual leaking of your infromation in it while they may pretend to fix a virus on your Mac. But leaking is the least of your worries, because the scammers also want you to pay them hundreds of dollars in order to fix the supposed issues on your Mac, that do not even exist.
