CPD Warns Public of Common Holiday Themed Scams
As the holiday season and shopping begins, potential criminals will look to perpetrate scams against shoppers and donors. The scams involve online shopping, charity, cryptocurrency investment, gift cards and social media.
Online shopping schemes include fraudulent websites or ads offering goods at unrealistic discounts, items purchased through third-party marketplaces using stolen credit cards or accounts and puppy scams involving fake advertisements for pets.
People should be on the lookout for fake charities soliciting donations through phone calls, emails, crowdfunding platforms, and social media. Also, copycat organizations create seemingly legitimate charities to steal funds.
Gift card scams involve requests for gift card purchases for alleged emergencies, work-related functions, or as payment, or tampered cards with compromised security stickers or altered barcodes.
Social media scams include posts offering fake gift cards or event tickets designed to steal personal information, or fraudsters duplicating ticket barcodes for resale.
