American Express built a new feature called Amex Passport that converts card transactions abroad into digital collectible stamps stored in its mobile app, using blockchain technology on the Base platform.

Amex has since expanded the feature to let cardholders generate stamps retroactively for trips dating back to 2019.

GuidePoint Security's research team found that attackers have breached at least 31 organizations—spanning e-commerce, professional services, and retail logistics—using a ClickFix campaign that leverages the Polygon blockchain to conceal command-and-control infrastructure. The technique, dubbed EtherHiding, lets attackers dynamically update C2 server locations via blockchain transactions instead of relying on a single fixed address.
