January 8, 2019

Buying heavily discounted, popular software from second-hand sources online has always been something of an iffy security proposition.

A new phone-based phishing scam that spoofs Apple Inc. is likely to fool quite a few people. It starts with an automated call that display’s Apple’s logo, address and real phone number, warning about a data breach at the company.

A year ago, KrebsOnSecurity warned that “Informed Delivery,” a new offering from the U.S. Postal Service (USPS) that lets residents view scanned images of all incoming mail, was likely to be abused by identity thieves and other fraudsters unless the USPS beefed up security around the program and made it easier for people to opt out.
