Enhance Security: Update Your Printer Firmware to Prevent Hacking

While most users routinely update the security patches for their computers, smartphones, and tablets, many overlook an essential device: the printer. Given the increasing number of cyber threats targeting networked devices, now is imperative to install the latest printer firmware updates to safeguard your network and connected devices against unauthorized access.

Understanding Printer Vulnerabilities

Despite being responsible for major cyber incidents, printers often go under the radar when it comes to security. This complacency can be dangerous; any network-attached device represents a potential gateway for cybercriminals. A recent investigation by Rapid7 in June revealed critical security flaws impacting over 700 printer models.

These vulnerabilities are currently being exploited by hackers who can take control of printers. Their motivations extend beyond draining your ink supplies; they often aim to install malware, repurposing these printers into botnets for malicious activities.

Once a botnet is established, it can facilitate a range of cyber assaults, including Distributed Denial of Service (DDoS) attacks, cryptocurrency mining, spamming campaigns, and data exfiltration. Consequently, neglecting to update your printer’s firmware not only jeopardizes your personal devices but also places others at risk, as your printer could unwittingly become a tool for harmful activities.

Identifying Vulnerable Printers

Though Brother printers are prominently targeted in this wave of attacks, they are not the only affected brands. It is crucial to consult the updated list of affected models to verify if your printer is vulnerable. If your model is listed, it does not mean hackers have successfully breached it yet, but it does signal an urgent need for a firmware update.

A Step-by-Step Guide to Updating Firmware

Even if your printer model isn’t on the vulnerability list, regularly updating your printer’s firmware is still a wise practice. Depending on the manufacturer, your printer might update automatically, but often you’ll need to initiate the process manually. Here are some common methods to update your printer firmware:

Utilize the printer’s dedicated update software, usually part of the printer’s software suite.
Access a web-based portal using the printer’s IP address (If you encounter connectivity issues, consult troubleshooting resources).
Download the firmware onto a USB drive and directly insert it into your printer.
Run the firmware update while your printer is powered on and connected to your network.
Use the printer’s display screen to initiate an update, if available.

For Brother printers, the steps typically involve visiting the manufacturer’s website. Navigate to the Support section (or similar, like Help or Resources) and input your printer model. Pinpoint your model number from the device, your computer settings, or the printer manual.

Once in the download section, select your operating system if required, and locate the firmware update files. For instance, download the Firmware Update Tool to securely push the update directly to your Brother printer.

Regardless of the brand, you should find relevant update instructions and files on the manufacturer’s website. The duration for completing a firmware update is often just a few minutes, although you might need to restart the printer post-update and potentially reconnect it to your devices or network.

Enhancing Security: Changing Printer Passwords

While many manufacturers are proactively releasing firmware updates in response to these vulnerabilities, another defensive measure involves changing your printer’s default passwords. Relying on factory-set admin passwords makes it supremely easy for cybercriminals to seize control of your device merely by referencing model and serial numbers.

By establishing a unique password, you can create an added layer of difficulty for hackers, who may be less inclined to target your printer for botnet activities, especially if their goal is simply to exploit easily obtainable devices.

To modify your printer’s password, consider these general approaches:

Access the printer through its software or app, navigating to the Settings or Security options to change the password.
Connect via a web browser to the printer’s IP, logging in with the default admin password, and then changing it accordingly.
Utilize the control panel on the printer to find settings for privacy and security where you can change the password.

Remember, cyber threats extend beyond printers; use this situation as a cautionary tale to remain diligent with firmware updates across all devices. Additionally, employing robust antivirus and anti-malware software can fortify the security of your connected devices.
