"Access To This MAC Has Been Blocked" in detail
This scam page shows a fake macOS Security message (a fake security warning) claiming that access to this Mac has been blocked for security reasons. It says a computer has been infected with Trojan Spyware, and email credentials, banking passwords, and Facebook login information have been compromised.
This site urges visitors to call 808-400-0297 (supposedly "Mac Support"). Scammers behind technical support scams try to extract credit card details, ID card information, or other sensitive details, or they urge people to pay for fake (or unnecessary) products or services.
