Long-Running Web Skimming Campaign Steals Credit Cards From Online Checkout Pages

Hold up, shoppers — your checkout page might be snitching on you. A Magecart web skimming campaign that's been running since 2022 is actively stealing credit card and personal data from compromised e-commerce checkout pages. This isn't some amateur hour hack — it's a sophisticated, long-term operation that's been flying under the radar while draining digital wallets.

The campaign targets payment pages specifically — those moments when you're typing in your card details thinking you're secure. Instead, malicious JavaScript gets injected, capturing everything you enter before it even hits the payment processor. It's like having a digital pickpocket standing right behind you at the register, except you can't see them and they're stealing from thousands of people simultaneously.

What makes this particularly nasty is the longevity — this isn't a smash-and-grab operation. These threat actors have been maintaining and evolving their infrastructure since 2022, suggesting they're in it for the long haul and the payouts must be substantial enough to keep them invested. They're not just stealing credit cards — they're grabbing personal data too, meaning they're building comprehensive profiles for identity theft or resale on dark web markets.

The technical execution is classic Magecart — compromising legitimate websites, injecting skimming scripts, and exfiltrating data to controlled servers. But the persistence shows these aren't script kiddies — this is organized cybercrime with proper infrastructure and maintenance cycles. They're watching for security updates and adapting their methods accordingly.

For e-commerce sites, this is a wake-up call — your payment pages are ground zero for financial theft. Regular security audits, monitoring for unauthorized script injections, and implementing proper Content Security Policies aren't just best practices anymore — they're essential survival tactics in an environment where threat actors are playing the long game.

For consumers, the advice remains frustratingly familiar but crucial: use virtual credit cards for online purchases when possible, enable transaction alerts, and be wary of smaller e-commerce sites that might not have robust security measures. Your data is currency in the digital underground — protect it like you would physical cash.
