Why Print Drivers Are Increasingly Becoming a Nightmare for Corporate IT

In July 2021, a report revealed that millions of computers dating back to 2005 contain a print driver that introduces a dangerous vulnerability, which cyberattackers could use to escalate system access privileges. This makes it possible for someone with no administrative access credentials to access restricted areas of a system and initiate an attack on a network and get access to sensitive data.

While the potential fallout of this vulnerability is huge, the discovery itself is not new. Print drivers have long been an attack vector for cybercriminals seeking to penetrate otherwise secure machines and networks. In addition, managing print drivers is time-consuming and cumbersome in hybrid and work-from-home environments, which leaves print driver security risks unmitigated.

By using a cloud-based print management solution, you can eliminate many of the challenges traditional print drivers present, as well as enjoy a convenient, straightforward experience—for both IT staff and employees.

Here’s why and how print drivers introduce vulnerabilities, the problems inherent in a traditional print infrastructure, and how a cloud print management solution creates a more productive, secure work environment.

The Traditional Print Environment Explained

In a traditional print environment, computers connect directly to the printer—through a network using an IP connection. When users connect via the network, they don’t have to physically connect their computer to the printer. Similar to other network-enabled connections, the printer and the computer are connected via Internet Protocol (IP). This enables the print job to go straight to the printer.

In addition, employees can install new drivers on their own computers, if this is something they’re allowed or able to do. Also, if all computers that connect to the network run the same operating system, a network admin can update all of the print drivers at the same time.

But this setup has disadvantages, too:

  • Admins and end-users spend considerable time installing drivers
  • When several people try to print at the same time, the system can get clogged up by all the traffic, resulting in the printer running out of buffer memory and not being able to print new jobs
  • It introduces vulnerabilities that allow hackers to escalate privileges. They then use these privileges to execute other attacks or access sensitive digital assets on your network

Traditional Print Driver Management’s Impact on Productivity

In addition to introducing security vulnerabilities, traditional print driver management can also significantly reduce productivity. IT admins are responsible for installing and updating print drivers across your organization. An install happens for various reasons, including:

  • Updates to improve functionality
  • Updates to address security vulnerabilities
  • Power outages that can damage the existing driver

Once an admin identifies the need for a new driver installation or update, they have to figure out which method to use, whether the update should be done on other machines as well, and how to fit this task into an already busy schedule. Installing and updating is not only time-consuming, but it can also pull IT staff away from other business-critical tasks.

Traditional Print Driver Management with a Remote or Hybrid Workforce

With more and more organizations incorporating remote or hybrid work options, it’s crucial to maintain an infrastructure that’s flexible and agile. Traditional print driver management is often incongruent with a remote or hybrid work ecosystem. It may not be feasible for admins to arrange and execute remote installs or initiate the videoconferences or Remote Desktop Protocol (RDP) connections necessary for remote users to start printing. This negatively impacts your organization’s security posture. For example, it can allow printers that aren’t updated to the latest certified driver to be a part of your network, making the network insecure.

With a cloud print infrastructure, not only can users connect to the printing system and submit their jobs easily and quickly, but if an update is required, the cloud print management provider takes care of it. This can free up enormous amounts of time for IT, which they can invest in other important projects.

The Potential Vulnerabilities Print Drivers Introduce to Your Security Architecture

Print drivers consist of software that enables your computer to communicate with a printer. They make sure the printer is available to perform the job, that there’s a link between your computer and the printer, and that the job gets sent directly to the printer you’re trying to use.

You may remember when people had to install drivers for USB devices. Similar to print drivers, these made it possible for your computer to interact with the external USB device. But in addition to simply forming a link, the print driver enables the computer to exercise control over the printer.

Printer drivers are useful for giving users a wide range of printing options. However, print drivers also introduce multiple security risks, such as basic default credentials, printing without permissions to unsecured printers, unauthorized configuration changes, and unauthorized data access and recovery.

If hackers exploit these vulnerabilities, they could install applications and create new user accounts, as well as access, change, delete, or encrypt data.

How Print Drivers Introduce Vulnerabilities

On Windows machines, in particular, vendor-provided drivers increase the chance of a vulnerability making it into your network. Because of the way the Windows system handles driver deployment, admins must implement print drivers as a shared resource using common protocols. IT teams may find it difficult to choose print drivers with adequate security measures, providing bad actors with a path to propagate their malicious payload across the network.

For instance, commonly used protocols, such as the Simple Network Management Protocol (SNMP), can be subject to man-in-the-middle attacks. During this kind of attack, a hacker transmits a large number of SNMP queries using a fake IP address to the printer, which the printer replies to. This paves the way for the hacker to take control of the printer. Once they have the control, they can manipulate print job schedules so they can physically steal sensitive documents later.

However, a far more dangerous vulnerability exists on printers with the ability to email scanned documents to users. An attacker can use the printer’s emailing capabilities to launch phishing attacks. These may be even more effective than typical spam-based phishing emails because they could look like they came from a trusted device: your printer.

In this kind of attack, the bad actor can leverage the control they gain over the printer via the SNMP protocol to send an email—one that looks like it came from the printer—to someone in your organization. The email could contain a link that downloads malware onto their computer or lead them to a site where they’re asked to enter sensitive login credentials. Because it seems like the message is sent by the printer, the victim may be caught off guard.

On the other hand, with cloud-based printing, you don’t have to depend on manufacturer-provided drivers or a network admin properly setting up all communication protocols for your organization to be able to print securely. You get secure, reliable printing at the get-go because print drivers and print driver management are no longer part of the equation.

Reducing Print Driver Vulnerabilities with a Cloud Printing Infrastructure

With a cloud printing infrastructure, you can reduce the possibility of printer vulnerabilities, such as PrintNightmare or lesser-known bugs like CVE-2021-3438, impacting your system. In general, this is how cloud-based printing works:

  • An admin installs an agent on each computer and device employees use for printing, which makes it possible for each device to print
  • An application on the network enables computers connected to it to access the cloud
  • The client agent on the computer or device buffers the job, storing it until it’s ready to go to the printer or uploading it to the cloud so it can be printed later

This process makes it possible for the document to be printed either from the cloud or directly from the user’s computer.

As a result, you eliminate the on-premises driver “middleman,” effectively removing a prime target for attackers. Cloud print infrastructure is more secure because the print data and information contained in documents gets sent directly to the cloud service using end-to-end encryption. Even if a hacker intercepts the data stream, they wouldn’t be able to read sensitive documents without the decryption key. In addition, you can configure your cloud-based printing solution to only print documents if a specific user is physically present at the printer. This prevents passersby or information thieves from getting their eyes on sensitive information.

Common threats in printing environments

Several threats can compromise the security of printed documents in a business environment. Some of the most common risks include:

Unauthorized Access

Without proper security measures in place, unauthorized users may access sensitive print jobs and view or distribute confidential information. This can happen when an employee prints a document to a shared printer and walks away, leaving the document unattended and vulnerable to theft.

Print Job Interception

Cybercriminals can exploit vulnerabilities in a networked printer to intercept print jobs as they’re transmitted from a computer to the printer. Once intercepted, the attacker can steal, alter, or even reroute the print job to a different location.

Printer Storage Breaches

Modern printers often have internal storage that retains a copy of printed documents. If the printer’s storage is not properly secured or wiped, cybercriminals can access these documents and retrieve sensitive information.

Document Disposal

Improper disposal of printed documents can lead to security breaches. Confidential information can be exposed if discarded documents are not shredded or otherwise destroyed in a manner that prevents unauthorized access.

Social Engineering Attacks

Attackers may use social engineering tactics to manipulate employees into providing access to sensitive print jobs or to reveal information about an organization’s printing processes. For example, an attacker may pose as a technician or a colleague to convince an employee to release a print job without proper authentication.

Insecure Mobile Printing

With the rise of mobile devices and remote work, employees increasingly print documents from their smartphones or tablets. If mobile printing is not secured, sensitive data can be exposed during transmission or when the document is printed.

To mitigate these risks and ensure the security of printed documents, organizations must invest in comprehensive secure printing.

Essential Features of Secure Printing Solutions

A robust secure printing solution helps organizations protect sensitive information, comply with industry regulations, and maintain the trust of their clients and stakeholders. To be effective, a secure printing solution must include a range of features designed to safeguard data at every stage of the printing process. The following are five essential features to consider when evaluating secure printing solutions:

User authentication

User authentication is a critical component of secure printing solutions, as it ensures that only authorized individuals can access and print sensitive documents. There are several methods of user authentication, including (but not limited to):

Username and Password

Users must provide a unique username and password combination to access the printing system. This method is simple to implement but can be less secure if users share their credentials or fail to create strong passwords.

ID Cards and Badges

Physical ID cards or badges embedded with magnetic stripes, barcodes, or RFID chips can be used to authenticate users at the printer. This method is more secure than relying on usernames and passwords, as it requires users to possess a physical token.

Mobile Authentication

With mobile authentication, users can use their mobile devices to scan a QR code displayed on the print device, which then sends a verification request to a secure mobile app. Once the user confirms their identity within the app, the print job is authenticated, and the document is released. This method is convenient, as it leverages the user’s mobile device, which is typically always at hand, and adds an additional layer of security by requiring the user to confirm their identity through the mobile app.

By implementing user authentication, organizations can prevent unauthorized access to sensitive print jobs and maintain control over who can print specific documents.

Secure print release

Secure print release is another vital feature of secure printing solutions. It ensures that printed documents are not left unattended at the printer, where they can be easily accessed by unauthorized individuals. Secure print release requires users to confirm their identity at the printer before a document is printed, either by entering a unique PIN or using an ID card, badge, or biometric authentication method.

Some secure printing solutions also offer “pull printing” or “follow-me printing” functionality, which allows users to send print jobs to a centralized queue and release them at any compatible printer within the network. This feature not only enhances security by ensuring that users are present when documents are printed but also improves efficiency by reducing the occurrence of unclaimed or duplicate print jobs.

Data encryption

Data encryption is essential for protecting sensitive information as it’s transmitted from a user’s computer to the printer. Secure printing solutions should employ robust encryption protocols, such as Secure Sockets Layer (SSL) or Transport Layer Security (TLS), to encrypt print jobs and prevent unauthorized access during transmission. Additionally, some solutions offer encryption for the printer’s internal storage, ensuring that any residual data stored on the printer is protected from unauthorized access.

Audit trails and reporting

Comprehensive audit trails and reporting capabilities are essential for monitoring and managing secure printing environments. Audit trails record all printing activities, including details about the user, the document, the printer, and the time and date of the print job. These logs can be invaluable for identifying potential security breaches, investigating unauthorized access, and ensuring compliance with industry regulations.

Reporting tools can analyze audit trail data to provide insights into printing patterns, identify potential areas of concern, and help organizations optimize their printing processes. Reports may include information on user activity, printer usage, print volumes, and security incidents. By regularly reviewing and analyzing these reports, organizations can proactively address potential vulnerabilities and continually improve their secure printing practices.

Mobile printing security

With the increasing prevalence of mobile devices and remote work, secure mobile printing has become a crucial component of any comprehensive secure printing solution. Mobile printing security involves protecting sensitive data as it’s transmitted from smartphones or tablets to the printer, as well as ensuring that only authorized users can access and print documents from their mobile devices.

This method is convenient, as it leverages the user’s mobile device, which is typically always at hand, and adds an additional layer of security by requiring the user to confirm their identity through the mobile app.

Network Security

Ensure that the wireless network used for mobile printing is secure, using encryption protocols such as WPA2 or WPA3. Additionally, consider segmenting the network to separate mobile printing traffic from other network activities, reducing the risk of unauthorized access.

Device Management

Implement mobile device management (MDM) solutions to control access to corporate resources, including printers, from mobile devices. MDM can help enforce security policies, monitor device usage, and remotely wipe data from lost or stolen devices.

Training and Awareness

Educate employees about the risks associated with mobile printing and the best practices for maintaining security. This includes using secure apps, authenticating print jobs, and following the organization’s mobile device policies.

By incorporating these strategies, organizations can enable secure mobile printing while maintaining the same level of data protection as traditional printing methods.

The Fundamentals of Printer Security

In many organizations, printers are unmonitored endpoints, making them a prime target — both for hackers and government officials aiming to boost cybersecurity. The president of the United States, Joe Biden, issued an executive order in January 2022 that stipulates a need for stronger endpoint detection services for government networks. Like other endpoints, hackers can use printers to infiltrate networks.

For example, in a gray hat hack, the cybersecurity team of CyberNews broke into 27,944 printers worldwide. Once inside, they forced each printer to print out a guide on making printing more secure. The top of the document reads, “This printer has been hacked. Here’s how to secure it.” A few elements of the “attack” are particularly sobering.

First, the hackers were able to penetrate 56% of the printers they targeted, which speaks volumes about the number of unsecured printers spread throughout the world’s offices. The attackers chose to limit the scope of their operation. Even though they could gain access to other features and sensitive data stored on the printers, they decided not to. A malicious attacker might not be so gracious. Here’s a straightforward breakdown of the security concerns posed by printers, why it’s essential to take them seriously, and how to make your print infrastructure more secure.

Security Concerns for Printers

As the CyberNews hack makes it all too clear, printers can provide an entry point into internal networks. Organizations that go to great lengths to train employees to avoid phishing attacks and credential theft may still be caught off guard by a printer hack.

The threat is particularly acute because a successful printer hack can allow attackers to persist unnoticed for months or longer. While they’re in your system, they may be able to see printed documents.

This is great news — for hackers. Suppose an attacker has gained access to one or more printers in your corporate office, and they can read the documents that are being printed. Anything that gets sent for printing, customer and employee data, company secrets, financial information, and more, is in full sight. And because the hackers can stay in the system for an extended period, they can simply wait until high-value pieces of information get sent for printing. Once that happens, they can use what they find to extort your organization, commit fraud or theft, or peddle it to someone else on the dark web.

Do You Need to Worry About Printer Security?

For these reasons, printer security should be a top priority for every organization. Not only are printers attractive targets due to the information that flows through them, but hacking them is relatively easy.

For example, Shodan, a search engine that finds internet of things (IoT) devices, is just a click away. The CyberNews team used this tool to identify vulnerable printers. The hackers only have to look for IP addresses with open ports and then confirm that they are, indeed, printers. While attackers may not specifically target your organization, they can use a search engine like Shodan to execute a query that could give them access to your printers.

The Dangers Posed by Remote Work Environments

Remote work has further increased the attack surface, specifically because it has presented more remote connections. Each employee that connects from home, therefore, may introduce a vulnerability. For example, remote workers may:

  • Print out sensitive work documents on home printers that haven’t been secured against attackers who could use tactics like the CyberNews hack to view them
  • Store sensitive documents in their printers’ queues, which can also be accessed by hackers
  • Travel to internet cafes or hotel business centers and print out sensitive documents to unsecured printers

Even industrious, trusted employees can make these kinds of mistakes. These oversights can expose your organization to attacks that would be much harder to execute in an in-office environment.

How Do You Make Cloud Print Solutions Secure?

In many ways, the answer is simple. After all, cloud printing is already more secure than an on-premise solution because it eliminates core vulnerabilities that come with a traditional print environment. But similar to a traditional environment, your first steps are to assess risk and use best practices.

Assess Risk

Assessing your risks is the first step in securing your print infrastructure because it gives you a more complete view of your attack surface. For example, you can ask questions such as:

  • How many remote employees connect to our network, and are they allowed to print at home?
  • What kinds of sensitive documents does our organization print?
  • Which departments tend to print documents that could attract hackers?
  • What security tools do we use to safeguard our print system?

Deploy Best Practices

Best practices that encourage a more secure print environment include:

  • Making sure employees safeguard any usernames and passwords they use to access your print system
  • Using multi-factor authentication for everyone who can print
  • Training employees about the ways hackers may try to access your print infrastructure and the kinds of information they may be after
  • Using a secure release system that ensures the person printing a document is present at the printer when it comes out

With a cloud print solution, it’s easier to address your risks and deploy best practices because it enables you to:

Eliminate Print Server Vulnerabilities

A cloud printing solution eliminates some vulnerabilities associated with an on-premise print server — such as malware spreading through your computers via an on-prem print server — because print management is orchestrated in a secure cloud environment. Also, some organizations may forget to update their print servers regularly. This can leave them vulnerable to hackers. According to a document produced by hackers for the Black Hat USA conference, hackers can execute denial-of-service, protection bypass, print job manipulation, and information disclosure attacks once inside your print server.

Implement End-to-End Encryption

With a cloud print infrastructure complete with end-to-end encryption, all sent data is encrypted. Without a decryption key, an attacker wouldn’t be able to read the information being sent. In this way, you help secure sensitive data in documents. Even if a hacker were to intercept something sent for printing, they would only get a jumbled hodge-podge of characters.

Perhaps a remote employee needs to send a printing job from a coffee shop to the office. With an encrypted cloud printing solution, they could do so without worrying about a hacker stealing it. A malicious actor using a man-in-the-middle attack wouldn’t be able to read the data they stole.

Deploy Zero-Trust

Zero-trust architecture presumes that every user, device, and network is a threat—and they remain so until they prove otherwise. With a cloud printing solution, you can ensure that people aren’t allowed to access your system unless they can provide multiple proofs of identity, including physical devices, biometric data, and things they know, such as passwords. You can also use a cloud printing environment to limit the devices allowed to send print jobs. Taking these steps can considerably shrink your attack surface.

Protect Sensitive Documents with Authenticated Print Release

Protecting sensitive documents is essential because it can protect:

  • Proprietary information that gets printed out
  • Employee identification data they or the HR department prints out
  • Data protected by government regulations, such as the Health Insurance Portability and Accountability Act (HIPAA) and the General Data Protection Regulation (GDPR)
  • Customer, patient, or student information sent to printers

Far too often, these kinds of documents end up in the wrong place at the wrong time — and in front of the wrong eyes. They are frequently left in printer output trays or piled on top of equipment or tables in offices without secure printing, where anyone can see them. This is both wasteful and risky.

But by using an authenticated print release system, you can keep the info in these documents safe. This secure printing procedure ensures that only authorized users have access to your printers, safeguarding the privacy of your important data.

How Authenticated Print Release Works

When you require authentication to release print jobs, you make it so an authorized user, such as the person who sent the job, must be physically present at the printer before the document gets printed.

For instance, if someone from HR had to print a document that contained an employee’s social security number, they could use secure release to ensure it stays in the print queue until they’re in front of the printer. 

The HR employee can bring a mobile device and scan a QR code attached to the printer. After the system authenticates the user, their document is immediately released from a secure queue.

To ensure document security or to simply finish crucial business activities, you can even submit print jobs from home, arranging for document release when a trustworthy colleague is present at the network device to collect it.

How Pharos Creates a Secure Printing Environment

With Pharos, you get a cloud printing solution that enhances both security and convenience. You can choose whether you want to send print jobs to the cloud or directly to the printer using IPPS or IPP protocols.

Pharos Secure Release print jobs can be saved in the cloud or on-premises. The Secure Release system can ensure an authorized user is at the printer to receive the document. Leveraging industry standards, Pharos Cloud also secures data with end-to-end encryption and encrypts any print jobs that are at rest but pending release to a secured printer.

To make it easier to implement a zero-trust policy, Pharos Cloud also verifies the identity of a user before enabling them to print by requiring an identity token and additional authentication if needed. By combining these features, you can create a more secure print infrastructure with Pharos.

Printer Security Risks

Printers Present Security Risks

It’s not news that network printers can pose risks to your organization’s security.

Printers can pose cybersecurity risks because they are often connected to networks and can potentially be accessed by unauthorized users.

Hackers may be able to gain access to sensitive information that is printed or stored on the printer.

In addition, malware can be transmitted through printer networks, which can compromise the security of the entire system. It is important to regularly update the firmware and security software on printers to reduce the risk of a cyber attack. It is also recommended to use strong passwords and to limit access to printers to only authorized users.

PrintNightmare: Securing Your Print Infrastructure


Since 2021, the “PrintNightmare” issue has become a topic of concern. This class of vulnerabilities affects Windows-based devices, including servers, desktops, and laptops. The vulnerabilities are found in the print spooler service, which is enabled by default and responsible for managing printers and printing documents. This article aims to explore the PrintNightmare problem, its implications, and long-term solutions to secure your print infrastructure.

The Print Nightmare Story

Understanding the Problem

In June of 2021, a vulnerability in Microsoft’s print spooler software, known as CVE-2021-34527 or “PrintNightmare,” was identified. This vulnerability allows remote network access to exploit the system, gaining privileged access rights and executing malicious code. It poses a significant risk as attackers can remotely control the affected system, potentially stealing sensitive data or disrupting operations.

Print Spooler Service: A Brief Overview

The print spooler service is responsible for managing printer connections and operations on Windows-based devices. It facilitates communication between the device and printers, ensuring compatibility by downloading and installing the required printer drivers. Additionally, it handles print jobs by organizing queues, prioritizing tasks, and buffering data into the printer’s memory.

Domain controllers also utilize the print spooler service for managing printers on a network. However, this introduces a security vulnerability, as any authenticated user can remotely connect to the print spooler service of a domain controller, compromising network security controls.

The print spooler service also allows Windows devices to act as print clients or print servers. While this ease of use is convenient, it grants privileged access to the print spooler service across the entire network, bypassing security controls and automatically updating printer drivers.

The Risk with PrintNightmare

The PrintNightmare vulnerability enables attackers external to the network to upload malicious code disguised as a Dynamic-link Library (DLL). This code can be executed with administrator privileges across the network, providing an entry point for further attacks and potential data exfiltration. The presence of proof-of-concept code circulating in the hacker community further exacerbates this risk.

Continuing Challenges

Although efforts have been made to patch the PrintNightmare vulnerability, new flaws in the Windows print spooler service continue to be identified. These vulnerabilities, such as CVE-2021-34481, pose critical risks, including local privilege escalation and potential Remote Code Execution (RCE) exploits. To mitigate these risks, it is recommended to temporarily stop and disable the print spooler service until all security patches are applied.

Long-Term Protective Measures Against PrintNightmare

Option 1: Patching and Praying

Keeping up with security patches for printer spooler service vulnerabilities provides a level of protection. However, the existence of well-resourced hackers who exploit vulnerabilities before patches are released poses a significant risk. Organizations must consider the potential consequences of falling victim to attacks targeting their intellectual property or sensitive information.

Option 2: Moving Print Services to a Secure Cloud-Based Solution

To effectively address the vulnerabilities introduced by Windows-based print servers, a long-term solution should eliminate the inherent weaknesses. Migrating print services to a secure cloud-based print management solution offers several advantages:

  1. Elimination of Printer Driver Management: Legacy communication protocols used by printer drivers often introduce security vulnerabilities. A cloud-based solution that eliminates the reliance on manufacturer drivers ensures secure connectivity by default.
  2. Improved Security Controls: By using a cloud-based service, the need for network-wide access and exceptions for print services is eliminated. This simplifies configuration and enhances overall security.
  3. Mitigation of Legacy Protocol Risks: Older operating systems rely on legacy print protocols that can be exploited. Cloud-based secure printing solutions enforce secure protocols, minimizing the risks associated with legacy support.
  4. Isolation of Print Functions: Dedicated print servers separate print functions from multi-use servers, reducing vulnerabilities and potential misconfigurations.
  5. Enhanced Encryption: Cloud-based secure printing solutions encrypt all print file transmission and storage, protecting against eavesdropping and unauthorized access.

Pharos Products and Log4j Exploit

December 15th Update: This blog post has been updated with new information as we learn more. For the latest information on Log4j impact on Pharos products and how we’re mitigating the risk of this exploit, please visit our Community Page


Recently, a new zero-day vulnerability in the popular Java library Apache Log4j (CVE-2021-44228) was uncovered. This vulnerability allows attackers to inject arbitrary code in Log4j versions 2.0-2.14.1. This Java library is widely used by multiple closed and open source projects. 

This vulnerability is rated critical (CVSS severity level 10 out of 10), with immediate patching or mitigation recommended if affected, because it allows a possible Remote Code Execution when an attacker sends a malicious code string that gets logged by Log4j. That string allows the attacker to load Java onto a server and therefore take control. 

Impact of Apache Log4j Exploit on Pharos Products

After initial review, Pharos believes that Pharos customers are not impacted by the Log4j JNDI exploit.  

A non-customer facing cloud component used by Pharos was potentially susceptible to log4shell – specifically ElasticSearch, which is used by Pharos to log events across our infrastructure. We have applied patches to all production environments. In addition, Pharos has scanned all our logs and confirmed that no attempts were made to exploit this vulnerability.  

Pharos uses Java in our embedded solutions for some devices; however, the vulnerable library version is not used.
