As businesses increasingly rely on digital tools to perform mission-critical functions, cyberattacks have become a worrying threat. Thieves target various aspects of our lives, from personal information to critical infrastructure, and while we often focus on securing our online interactions, there’s a lesser-known threat that could potentially wreak havoc – cyberattacks executed via print networks. This Industry Analysts report about a ransomware attack in the healthcare industry shows that the vulnerabilities of seemingly innocuous devices like printers can expose us to significant risks. Let’s explore the dangers of cyberattacks perpetrated via print networks and shed light on the importance of securing these often-overlooked devices.

The Unseen Threat

Printers have come a long way from their humble beginnings as mere document output devices. Modern printers are complex, connected devices that can perform functions beyond just printing, including scanning, faxing, and even integrating with cloud services. As these devices have evolved, so too have the vulnerabilities that can be exploited by cybercriminals.

One of the most significant dangers of print network cyberattacks is that they often go unnoticed. While firewalls, antivirus software, and other cybersecurity measures are usually in place to protect our computers and servers, printers are often overlooked. This oversight makes them an attractive target for hackers, as they can use compromised printers as a gateway into larger systems or networks.

Attack Vectors

1. Malware Injection: Hackers can inject malicious code into print jobs, which can then be executed by the printer. This could lead to data theft, unauthorized access, or even the spread of malware to other devices connected to the same network.

2. Data Interception: Cybercriminals can intercept print jobs containing sensitive information, such as financial records or personal documents. This information can then be used for identity theft or financial fraud.

3. Printer Manipulation: An attacker gaining control over a printer could alter settings, redirect print jobs, or even render the printer unusable. This could disrupt business operations and lead to data loss.

4. Network Access: Compromised printers can be used as a foothold to gain access to the broader network, potentially exposing critical systems and sensitive data to unauthorized individuals.

Real-world Examples

Several incidents highlight the potential dangers of cyberattacks executed via print networks:

1. The Shadow Brokers: This group leaked classified NSA tools, one of which was used to exploit vulnerabilities in older printer models. This demonstrated how even intelligence agencies can overlook the security of seemingly unimportant devices.

2. Faxploit: Researchers found a vulnerability that allowed them to take control of a multifunction printer by sending a malicious fax. This incident exposed the risks associated with outdated communication protocols.

3. Prospect Medical Holdings: This healthcare-industry attack disrupted operations at multiple locations, forcing some hospitals to close their emergency departments and revert to paper records.

Mitigation Strategies

1. Regular Updates: Keep printer firmware and software up to date to patch vulnerabilities.

2. Segmentation: Separate the print network from critical business networks to contain potential attacks.

3. Access Control: Implement strong authentication methods to restrict printer access to authorized personnel only.

4. Network Monitoring: Regularly monitor printer activity for anomalies that could indicate a breach.

5. User Education: Train employees to recognize phishing attempts and the risks associated with printing sensitive information.

As we integrate more devices into our interconnected digital ecosystems, it’s crucial to recognize that cyberattacks can come from unexpected angles. Printers, often viewed as mundane office tools, hold the potential to compromise our cybersecurity efforts if left unprotected. By acknowledging the dangers of cyberattacks via print networks and taking proactive measures to secure these devices, DEX Imaging stands ready to help you strengthen your overall cybersecurity posture and safeguard sensitive information from lurking threats.
