Cybersecurity for:
E-commerce & Retail

Why is e-commerce a target for cyberattacks?

Online stores are ideal targets — they process payment card data, store personal information of millions of customers, and generate revenue in real time. Every hour of downtime is a direct financial loss. Attackers know that e-commerce operators will pay ransoms to restore operations before Black Friday or other promotional events.

Additionally, e-commerce platforms connect many components: payment systems, courier gateways, CRM, marketing automation, and marketplace integrations. Each of these integrations is a potential attack vector.

Sector-specific challenges

Magecart attacks and JavaScript skimmers

Magecart attacks inject malicious JavaScript code into checkout pages. The skimmer operates in the customer’s browser, intercepting payment card data at the moment of entry. Traditional server-side security scanners cannot detect this type of attack because the malicious code loads from external sources or hides within legitimate JS libraries.

Credential stuffing and account takeovers

Bots test billions of stolen login/password pairs against store login pages. One compromised customer account provides access to saved cards, order history, and personal data. A large-scale credential stuffing attack can overload infrastructure like a DDoS attack.

Payment fraud and chargebacks

Transactions with stolen cards generate chargebacks that cost the store not only the product value but also penalty fees from the payment processor. An excessively high chargeback rate can result in losing the ability to accept card payments entirely.
