31 Organizations Hit in ClickFix Attack Using Polygon Blockchain to Hide C2 Servers
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.
