Many (most?) of you have seen those annoying captchas that are designed to see if you are a human. They often don’t really stop hackers but the always annoy users.
And, recently, you have likely seen different ones on different websites, so you don’t really know if you see a different one whether it is real or a scam.
This one is a scam.
The window above is what you see. What it is asking you to do is to run a program that the malicious website has downloaded in the background.
THE PROGRAM COULD DO ANYTHING. ANYTHING AT AL.
If you get this request when you go to a website it is, pretty much, a 100 percent guarantee that the site is malicious.
That doesn’t mean that the site started out that way. It could be that the owner didn’t secure the site and as a result, it has been hacked.
Either way, LEAVE THE SITE IMMEDIATELY. CLOSE THE BROWSER. DO NOT GO BACK THERE.
