Microsoft recently reported that tech support scams are up 24 percent since last year. The tech giant received 153,000 reports of customers encountering or falling for a fraud attempt, with 1 in 10 actually losing money from those scams. Microsoft customers paid an estimated $3 to $6 million to criminals – all because they didn’t know how to spot a hoax.

The Better Business Bureau recently warned Netflix users that searching for a Netflix customer support number online might lead to some nefarious results.

Some legitimate-looking customer service phone numbers really belong to scam artists.

When a Netflix user calls one of these numbers, the scammer (posing as a Netflix “representative”) informs the user that his or her account was hacked. The scammer then requests access to the Netflix user’s computer to “fix the problem.”
