Securing Wireless Peripherals in Shared Office Spaces
Article summary: Wireless keyboards, mice, and headsets are treated as low-risk office staples. In shared workspaces, they are often left connected, unmonitored, and running firmware that is rarely updated. Wireless peripheral security requires the same attention as any other endpoint: awareness of known attack vectors, consistent firmware hygiene, and a clear policy for who owns each device.
A wireless keyboard can expose far more than a few typed words.
Every day, employees enter passwords, client information, financial data, and internal communications through devices that most organizations never inventory, monitor, or update.
Wireless keyboards and mice are often treated as simple office accessories. In reality, they are connected devices that communicate over radio signals and can introduce security risks if left unmanaged.
That becomes especially important in shared workspaces, where peripherals move between users and security oversight is often minimal.
Keeping those devices secure is part of managed IT security for any business with shared or open workstations.
What Attackers Can Do with Your Wireless Peripherals
MouseJack is a class of vulnerabilities that affects the vast majority of non-Bluetooth wireless keyboards and mice.
Using roughly $15 in hardware, an attacker can inject keystrokes into a vulnerable device from up to 100 meters away.
According to research by Crowe cybersecurity, a majority of wireless mice do not use an encrypted connection to their USB dongle. That opens the door to keystroke injection and full remote control of the connected computer without physical access.
A separate class of attacks called KeySniffer targets older non-Bluetooth devices that transmit keystrokes without encryption over 2.4GHz radio.
In those cases, everything typed passes through the air in clear text, readable by anyone with basic radio equipment within range.
In early 2024, security researcher Marc Newlin disclosed CVE-2023-45866, a Bluetooth vulnerability affecting Android, Linux, iOS, and macOS devices.
According to CSO Online, the flaw allowed a nearby attacker to trick vulnerable devices into pairing with a rogue Bluetooth keyboard and inject keystrokes without user approval. Devices that had not received the appropriate security updates remained exposed.
Why Shared Spaces Raise the Exposure
Hot-desking, coworking arrangements, and open-plan offices change the ownership equation. When a keyboard belongs to a desk rather than a person, nobody is responsible for its firmware. It gets plugged in, paired, and left.
Devices also accumulate in shared environments without IT involvement. An employee brings in a peripheral, uses it for a few weeks, and moves on. The dongle stays plugged in.
The device stays paired. Nobody revokes it because nobody knows it is there.
This mirrors the ghost account problem. Our post on finding and terminating forgotten ghost accounts covers the same principle: access that was granted informally and never reviewed is the access that eventually causes a problem.
Practical Controls for Shared Wireless Devices
Know what is connected
Wireless peripherals rarely appear in asset inventories.
Run a periodic check of USB devices connected across shared workstations and note the manufacturer and model. Then search the manufacturer site for known vulnerabilities. Devices over four years old running non-Bluetooth 2.4GHz radio are the highest-risk category.
Update firmware where available
Not all peripherals support firmware updates.
For those that do, the manufacturer site is the right place to check.
Some older wireless peripherals cannot be secured through firmware updates because the necessary protections were never built in. In those cases, replacement is the fix.
Power down or unplug between sessions
A peripheral that is powered off cannot be exploited.
In shared spaces, a clear end-of-session habit covers most opportunistic attacks: lock the workstation, unplug the dongle or switch off the device.
Use wired peripherals for high-sensitivity roles
Finance, HR, and executive workstations process data that is genuinely worth targeting. A wired keyboard carries no radio-based attack risk.
Building a Policy That Gets Followed
The goal is visibility and ownership.
Every peripheral in a shared space should be listed somewhere, assigned a responsible party, and checked at regular intervals.
The same approach used to audit for continuous monitoring gaps works here: set a schedule, do the check, and document the result.
Simple beats elaborate. A one-page device policy covering registration, firmware checks, and session habits is more likely to be followed than a complex security program no one reads.
Ready to Audit Your Wireless Device Exposure?
Wireless peripheral security is easy to overlook because the devices seem ordinary.
That is exactly why they deserve attention.
Known, exploitable vulnerabilities exist in wireless keyboards and mice that are still sitting on desks today, often running firmware that has not been updated in years. Unlike laptops and servers, these devices rarely receive regular security reviews. Once installed, they tend to remain in service until they stop working.

Article FAQs
Are wireless keyboards and mice really a security risk?
Yes, particularly older non-Bluetooth devices that communicate over 2.4GHz radio without encryption. Vulnerabilities like MouseJack allow attackers to inject keystrokes or intercept typed content from distances up to 100 meters using inexpensive hardware.
What is MouseJack?
MouseJack is a class of vulnerabilities affecting non-Bluetooth wireless keyboards and mice that connect via USB dongle. Because most wireless mice do not use encrypted connections, an attacker in range can inject keystrokes and take control of the connected computer without being physically present.
Are Bluetooth devices safer than 2.4GHz dongles?
Generally yes, because Bluetooth includes standardized security protocols that most proprietary 2.4GHz designs lack. However, Bluetooth is not without vulnerabilities. CVE-2023-45866 demonstrated that even paired Bluetooth keyboards can be exploited on unpatched systems.
Should we replace all wireless peripherals?
Not necessarily. Priority replacements are older non-Bluetooth devices with known vulnerabilities and no available firmware patch. For devices that support firmware updates, apply them. For high-sensitivity workstations in finance or HR, wired peripherals remove the radio attack surface entirely.
