Paper-Thin Defenses: Fortifying Your Business Against Printer & Copier Cyber Threats

As technology continues to advance, so do the risks associated with it. One area often overlooked in terms of cyber security is printers and copiers. These seemingly harmless devices can become potent tools for cyber attackers if not properly secured. In this article, we explore the vulnerabilities present in copiers and printers, the potential risks they pose, and the measures businesses can take to protect themselves.


Printer Cyber Vulnerabilities


Recent headlines on the internet have shed light on the numerous vulnerabilities found in printers and copiers. For instance, Microsoft recently issued a patch to address a significant exploit in Windows' Printer Service, while the "PrintNightmare" vulnerability posed serious risks to system security. Additionally, specific printer models from well-known brands like HP were exposed to critical security flaws.


Default Passwords: A Common Weakness


One of the primary reasons printers and copiers become easy targets for cyber attacks is the prevalence of default passwords. Some manufacturers publish these default logins on their websites, giving attackers a convenient entry point. This vulnerability allows both attackers and legitimate users to gain initial access to a printer or copier, making it crucial for businesses to change these default credentials.


Risks and Consequences


The potential consequences of leaving printers and copiers unprotected can be severe. These devices often handle sensitive documents, such as checks, vendor invoices, utility bills, and bank statements. Moreover, they usually come equipped with internal hard drives that store printed and copied information for extended periods.


Insecure Wi-Fi Connections


Another concerning issue is the prevalence of printers and copiers with Wi-Fi functionality. Many devices are still shipped with default Wi-Fi credentials, which can be easily found on the manufacturer's website. This presents an opportunity for attackers to exploit weak Wi-Fi security, even from remote locations, and gain unauthorized access to the device.


Data Leakage and Unauthorized Access


An attacker exploiting a vulnerable printer or copier can potentially intercept sensitive information stored within the device's internal storage. For instance, they could access bank account numbers, check numbers, and other confidential data. This information can be misused for various malicious purposes, leading to financial loss, identity theft, or other severe consequences.


Secure Disposal of Devices


The proper disposal of copiers and printers is essential to prevent data leaks. Many of these devices contain storage devices that retain images of copies made. Therefore, companies must follow established electronic device disposal processes, similar to those used for laptops and desktop computers. This process requires wiping all data from the internal storage devices to ensure sensitive information doesn't fall into the wrong hands.


Protecting Your Business


To ensure the security of copiers and printers within your organization, proactive measures are necessary. Here are some steps you can take:

  1. Patch Management: Regularly update the firmware and software of your printers and copiers to protect against known vulnerabilities. This can be done by your IT department or a trusted cyber security company.

  2. Change Default Credentials: Immediately change default passwords on all devices to strong, unique passwords that are not easily guessable.

  3. Secure Wi-Fi Connections: Disable Wi-Fi if not required, and if necessary, ensure that it is encrypted using WPA2 or higher protocols with strong passwords.

  4. Network Segmentation: Separate printers and copiers from critical systems by placing them in their own network segment to minimize potential damage from a successful attack.

  5. Cyber Security Assessment: Hire a reputable cyber security company ,like 5Q, to conduct a comprehensive assessment of your devices, identify vulnerabilities, and recommend necessary remediations.

The significance of securing copiers and printers in today's digital landscape cannot be overstated. Neglecting these seemingly insignificant devices can lead to severe data breaches and financial loss. By taking proactive steps to mitigate vulnerabilities, businesses can safeguard themselves from potential cyber attacks and maintain the confidentiality of sensitive information. Prioritizing printer and copier security is an integral part of any comprehensive cyber security strategy.
