Tech-support scams are all about deception and trickery, such as fake Blue Screen of Death (BSOD) warnings and other browser pop-ups with fake security warnings that invariably aim to convince users to call a hotline and pay to fix a contrived security problem.
A victim would still need to press call but the technique allows scammers to use simpler communications, such as, "We're here to help" rather than legit-looking system warnings.
As noted by Microsoft, the scam site is targeting both Apple and Microsoft users and caters to users of desktops and smartphones.
Instead of scary dialog boxes, the site Microsoft found plays an audio message to warn users about a supposed "critical alert from Apple support". The message reads:
"Critical alert from Apple support. Your mac has alerted us that your system is infected with viruses, spywares, and pornwares. These viruses are sending your credit card details, Facebook logins, and personal emails to hackers remotely. Please call us immediately on the toll-free number listed so that our support engineers can walk you through the removal process over the phone. If you close this window before calling us, we will be forced to disable and suspend your Mac device to prevent further damage to our network. Error number 268D3."
Microsoft believes the tech-support scam site is being sold as a service on cybercrime forums.
