Barcode Scanner Flaw Exposes Warehouse Networks

A Single Scanner Could Put a Network at Risk

As e-commerce expands, warehouses, retail operations and logistics systems are becoming increasingly technology-dependent. Since 2019, global e-commerce sales have nearly doubled, surpassing $6 trillion. Against this backdrop, researchers at Kaspersky Security Services have identified a vulnerability in a barcode scanner model from a leading manufacturer that could be exploited to launch cyberattacks. The risk could extend to warehouses, retail operations and other industries.

Handheld barcode scanners typically communicate through a base station, which is connected to a workstation or a business system. According to the researchers, the scanner and its base station lack authentication between them. This could allow someone within wireless range to exploit the weakness through keystroke injection—a technique that sends inputs resembling keyboard presses to a connected system. Under the right conditions, this could enable unauthorized activity without the user realizing what is happening.

How the Attack Could Work

Suppose an attacker discovers the Bluetooth address of the relevant base station. The attacker could then transmit a malicious payload designed to resemble keyboard input. If the base station forwards that input to the connected computer, the vulnerability could create an opportunity to execute commands without authorization. The research report describes similar situations observed across multiple devices.

An attack of this kind could provide a route into an organization's network, potentially putting critical operational systems and routine business activities at risk. The concern is not limited to barcode scanners: portable data terminals and thermal printers may face similar risks. Depending on the circumstances, compromised connected devices could become entry points for attempts to gain unauthorized access to important systems, including warehouse management platforms.

Every Connected Device Can Become an Entry Point

Sergey Sidorov, Head of Industrial Security Services at Kaspersky, said: “Modern retail and logistics have become fully digitalized. Everything is interconnected, from an organization's management platform to the devices employees carry in their hands. As a result, virtually any technology can become an entry point for a cyberattack capable of disrupting an entire operation. Our research shows that a single barcode scanner can be enough to create this risk. Cybersecurity must therefore be given the highest priority at every level of the warehouse and retail industries.”

Measures to Reduce the Risk

Kaspersky recommends verifying devices before connecting them to a network. It also advises organizations to keep security systems up to date, disable Bluetooth interfaces that are not in use and implement strong authentication.

Additional recommendations include network segmentation, which divides a network into separate sections to help control access; regular checks of potential entry points; and restricting account permissions to the minimum required for each user. These measures can help reduce unauthorized access and limit the possibility of a vulnerability in one device spreading risk across an entire network.

Kaspersky ICS security assessment services examine industrial control systems, operational technology and network-connected devices to identify vulnerabilities. According to the company, these assessments are designed to run without disrupting the devices' other operations.

Kaspersky's industrial cybersecurity services also aim to improve the visibility and security of infrastructure used by logistics companies and other industrial organizations. The objective is to strengthen the protection of critical digital infrastructure without compromising normal business operations.
