Pennsylvania Attorney General Dave Sunday warned people to be on the lookout for a trending cyber scam that involves the scammer sending “invoices” through PayPal.

Scammers use PayPal to send requests for payment to an email inbox, sometimes repeatedly, making the matter appear urgent. The messages attached to the requests often contain a toll-free number and a directive to call — that call line goes to the scammer, who will try to obtain personal information.

“This is another example of the sophistication of cyber scams, and a reminder to pause and be vigilant before offering personal information or sending money online,” Sunday said.

Consumers are advised to take two steps: Check the email address. If the email is not from the “service@paypal.com” email address, ignore it. Check the request. Even if the invoice appears to be coming from a legitimate address, if you don’t recognize the payment being requested, it is safest to ignore it.

If you receive a concerning invoice from PayPal, contact PayPal customer service at PayPal.com.

Consumers may also file a complaint with the Office of Attorney General.
