Each year, several million people fall for tech support scams. In 2015 alone, crooks walked away with an estimated $1.5 billion according to Microsoft. Once simply conducted by telemarketers through “cold calling,” now scammers pay to have their tech support line number listed on websites or use pop-ups to get victims to call them. Instead of receiving help, the user finds their computer held ransom. These tech support scams aren’t easy to spot. Their tactics have become so advanced (with real company logos, signatures of legitimate tech support offers and digital targeting); almost anyone could fall for their tricks.
