Magecart Web Skimming Campaign Exposes Payment Providers and Customers
Between January 2022 and January 2026, cybersecurity researchers uncovered an advanced web skimming campaign attributed to Magecart-related actors, compromising numerous e-commerce and payment websites linked to major providers including American Express, Mastercard, and others. The attackers injected heavily obfuscated JavaScript skimmers via domains controlled by sanctioned bulletproof hosts, notably Stark Industries and THE.Hosting, enabling the theft of sensitive credit card and personal data from unsuspecting users during checkout. The malicious code leveraged techniques to evade administrator detection and selectively harvested data before exfiltrating it through external servers, ultimately exposing customers and enterprises to widespread data theft risks. The discovery highlights a sustained increase in sophisticated client-side web skimming attacks leveraging supply chain weak points and exploiting trust in major payment platforms. The evolving tactics, regulatory expectations for PCI and consumer protection, and the broadening scope of victim organizations make ongoing vigilance and technical controls imperative for all businesses accepting online payments.
