Kaspersky has identified a flaw in a widely used barcode scanner model that does not require authentication between the handheld scanner and its base station. An attacker within wireless range can inject malicious keystrokes that the base station forwards to the connected computer.
Why it matters
The base station forwards inputs without authentication, creating a route to remote code execution on connected systems. Kaspersky warned that portable data terminals and thermal printers could offer additional routes into warehouse environments.
The attack requires only wireless range to obtain the base station's Bluetooth address, after which a malicious payload imitating keystrokes can be sent. Kaspersky's analysis indicates the vulnerability is not confined to one vendor, though the affected models have not been fully enumerated.
The players
Kaspersky
Kaspersky is a global cybersecurity company known for threat research and antivirus products.
The details
Kaspersky researchers uncovered the attack vector while auditing a digital warehouse ecosystem. The findings were presented at the Security Analyst Summit 2026 in Bali.

The Tech Race
The disclosure highlights how unauthenticated Bluetooth links between handheld scanners and base stations in warehouse hardware create a path into enterprise computers. It extends the scrutiny of industrial peripherals that has grown as warehouses adopt more connected devices.
Warehouse workers and operators using affected scanners could have their connected computers exposed to injected commands. Organizations should check whether their scanner base stations require authentication before trusting input from handheld units.
The takeaway
Organizations relying on wireless barcode scanners should verify that base stations authenticate their handheld devices. Treating peripheral input as trusted can open a path into the systems behind them.
