# What happens if an office PC infected with malware can reach the shop tills?

The malware can try to spread to the tills, steal card data or lock them, and the shop may stop taking payments. Attackers who get into an office computer through phishing usually look around the network next. If the tills and payment devices are on the same flat network, they are within reach, often with older software and weak passwords. The consequences range from lost sales while tills are down to a card data breach, with notifications to your payment provider and possibly customers. Prevent it by separating the payment network, keeping tills updated and changing default passwords. NetSenX helps you see it in time: scanning and lateral movement from an office PC toward the tills raise alerts on every plan.
