Attackers somehow manage users to get visited a malicious website, commonly through malvertising or compromised website.
Generally, tech support scam’s perform fingerprinting, according to researchers “this particular scam goes a step further and retrieves the browser version as well and redirects the user based on the browser name and version”.
Also, it play’s audio in the background stating that the computer is infected once the user arrives at the scam page.
Then it inform’s users that their computer has been blocked due to a malware infection and tempt user’ to call the number displayed on the screen for assistance.
According to Symantec research, the scam page uses a call optimization service’s advanced JavaScript integration service that return’s scammer phone number from the server and triggers a call back function.
By having the call optimization enabled, attackers, make sure correct phone number displayed to the user’s based in multiple countries.
