In today’s increasingly connected world, printers and copiers have evolved beyond simple output devices. Many are now networked, multifunctional devices that manage critical business processes, handle sensitive data, and even interface with cloud services. However, this evolution has also made them attractive targets for cybercriminals. As organizations prioritize securing servers, desktops, and mobile devices, printers and copiers often slip under the radar, providing a weak link in the security chain.

This post explores the growing threat of printer and copier attacks, why these devices are being targeted, and how businesses can effectively mitigate the risks.

The Growing Threat of Printer and Copier Attacks

Many businesses don’t realize that their office printers and copiers are small computers with built-in storage, operating systems, and connectivity to the broader network. This makes them vulnerable to the same kinds of attacks that affect other networked devices.

Recent years have seen a rise in printer and copier-related security breaches, including:

• Data theft: Printers and copiers often store documents in internal memory, sometimes indefinitely. Cybercriminals can access sensitive information (e.g., financial reports, contracts, or confidential client details) stored on these devices.
• Network intrusion: Once a hacker gains access to a networked printer, they can move laterally across the network, exploiting other devices and systems. Unpatched printers and copiers become entry points for malware or ransomware attacks.
• Denial of Service (DoS) attacks: Attackers can overload printers with traffic, causing system outages that disrupt day-to-day operations.
• Command and control systems: Hackers have been known to use compromised printers and copiers as part of botnets, using them to launch further attacks without the knowledge of the organization.

Why Are Printers and Copiers Targeted?

The targeting of printers and copiers by hackers stems from several factors:

• Neglected Security Measures: Printers often lack the same level of scrutiny and security protocols as servers and computers. They are usually installed, configured, and forgotten.
• Outdated Firmware: Many organizations fail to keep their printers updated with the latest firmware, leaving them vulnerable to well-known exploits.
• Weak Access Control: Default usernames and passwords are often left unchanged, giving attackers easy access. Additionally, many companies fail to restrict access to printer management interfaces.
• Data Sensitivity: Printers and copiers regularly handle and store sensitive documents. Hackers can exploit the lack of encryption or security protocols to steal critical business information.

Mitigation Strategies: Protecting Printers and Copiers from Hackers

The good news is that businesses can protect themselves from these threats by implementing some key security measures. Here’s how to safeguard your print infrastructure:

1. Update Firmware and Patches Regularly

Printers, like any other network device, require regular updates. Ensure that your IT team or managed print service provider schedules routine firmware updates and security patches to address known vulnerabilities.

2. Change Default Credentials

One of the simplest yet most critical steps is changing the default username and password on all printers and copiers. Use strong, complex passwords and consider implementing multi-factor authentication (MFA) where possible.

3. Secure Network Access

Restrict access to printer management interfaces to authorized personnel only. Ensure that printers and copiers are segmented from other critical network infrastructure using Virtual Local Area Networks (VLANs). Only allow trusted devices to communicate with printers, and disable unused protocols and ports.

4. Encrypt Data in Transit and at Rest

Enable encryption for all data that passes through or is stored on printers and copiers. This will prevent unauthorized parties from accessing sensitive information, even if the device is compromised.

5. Implement Print Job Authentication and Monitoring

Use print job authentication to ensure that only authorized users can retrieve documents. Features such as pull printing, which requires users to authenticate themselves at the device before a print job is released, can help prevent unauthorized access to printed documents.

6. Audit and Monitor Printer Activity

Regularly audit your printer logs to monitor for suspicious activity. Many modern printers can generate reports and alerts for unauthorized access attempts or unusual behavior. This proactive monitoring can help you detect and respond to attacks more quickly.

7. Work with A Managed Print Service Provider

If managing printer security in-house is a challenge, consider partnering with DEX Imaging, a nationwide independent managed print service (MPS) provider. We offer comprehensive security solutions that include monitoring, updating, and securing your entire print environment.

Summing It Up

Printers and copiers are vital components of any business, but they’re often overlooked from a cybersecurity perspective. As the number of cyberattacks targeting these devices continues to rise, it’s crucial for businesses to recognize the threat and implement robust security measures. By keeping firmware updated, enforcing strong access controls, encrypting data, and monitoring printer activity, organizations can significantly reduce the risk of a costly breach.

In an era where every connected device is a potential entry point for hackers, no aspect of your IT infrastructure should be left unsecured — and that includes your printers and copiers.
