Hackers Could Break Into Warehouse Systems Through Wireless Barcode Scanners

Cybersecurity experts at Kaspersky have discovered a security weakness in wireless barcode scanners used in warehouses and retail businesses. This weakness could allow hackers to access warehouse computers and business software through Bluetooth connections.

Warehouses use wireless barcode scanners to scan products, track inventory, and manage orders. These scanners usually communicate with a base station, which is connected to a computer or another business system.

Kaspersky found that some scanner systems do not properly verify whether the device communicating with the base station is authorized to do so. This lack of authentication could create an opportunity for hackers to attack the system.

In a possible attack, a hacker could identify the Bluetooth address of the base station by monitoring wireless communications. The hacker could then send malicious data to the base station, making it appear as though the data came from a keyboard.

The base station would forward this data to the connected computer. Because the computer could interpret the data as normal keyboard input, the attacker might be able to execute unauthorized commands and gain access to the warehouse’s computer network.

The risk may extend beyond barcode scanners. According to Kaspersky, similar attacks could potentially target other warehouse devices, including portable data terminals and thermal printers.

If an attacker successfully gains access to a computer connected to the warehouse network, the attack could potentially spread to other systems, including the warehouse management system (WMS).

A WMS is software that helps businesses manage inventory, track products, process orders, and coordinate warehouse operations.

Such an attack could disrupt warehouse activities and put important business information at risk.

Modern warehouses rely heavily on connected devices and digital systems. Barcode scanners, computers, printers, and inventory management software work together to keep operations running smoothly.

However, if even one device has a security weakness, it could become an entry point for a larger cyberattack.

Sergey Sidorov, Head of Industrial Security Services at Kaspersky, emphasized that businesses must protect every layer of their digital infrastructure. Even a small device, such as a barcode scanner, could pose a risk to the wider network if it is not properly secured.
