When you think about the top cybersecurity threats in your workplace, you likely consider phishing emails, malware, or weak passwords. But what if I told you that your office printer—the device quietly working in the corner—could be one of the most significant vulnerabilities in your entire network?
It may sound unbelievable, but cybercriminals actively target printers. Many companies underestimate the security risks these devices pose—until it's too late. In 2020, Cybernews conducted the "Printer Hack Experiment." From a sample of 50,000 printers, they successfully breached 56%, forcing nearly 28,000 printers to print a warning about printer security. This highlights how businesses often overlook this seemingly harmless office equipment.
Why Are Printers Such a Target?
Because printers hold a treasure trove of sensitive information. They handle everything from payroll and contracts to confidential client data. Yet, many organizations leave them vulnerable to attack.
Here’s what happens when a hacker gains control of your printer:
●
Printers retain sensitive data - Every time you print, scan, or copy, your printer stores digital copies. Many models include built-in hard drives that can hold years of documents like payroll records, contracts, and employee files. If breached, hackers can steal or reproduce these files without detection.
●
Default passwords make hacking easy - Most printers come with simple default admin credentials like "admin/admin" or "123456." Many companies never update these, making it effortless for attackers to seize control.
●
They provide a gateway into your network - Connected to your WiFi and company network, compromised printers can serve as entry points for malware, ransomware, or data theft from other devices.
●
Print jobs can be intercepted - Without encryption, hackers can capture documents before they print. This exposes sensitive contracts, legal files, and medical records.
●
They can spy on your business activities - Many modern printers feature built-in storage and scan-to-email functions. If compromised, attackers can remotely access scanned documents, emails, and stored files.
●
Outdated firmware creates vulnerabilities - Like all devices, printers require regular security updates. However, most organizations neglect firmware updates, leaving printers exposed to known exploits.
●
Data risks from discarded printers - Improperly discarded printers can be a goldmine for hackers. Residual data on old devices can be harvested, leading to breaches and legal liabilities. Always ensure printer storage is wiped clean before disposal.
Protecting Your Printers From Cyber Attacks
Knowing printers are vulnerable, take these essential steps right now:
- Change Default Passwords - Replace default login credentials immediately with strong, unique passwords just like you would for your email or banking accounts.
- Update Printer Firmware - Manufacturers issue security patches for a reason. Regularly check for updates yourself or have your IT team handle it.
- Encrypt Print Jobs - Activate Secure Print and end-to-end encryption to protect documents from interception.
- Restrict Printing Access - Implement access controls so only authorized personnel can print. Use PIN codes for sensitive documents, and consider a guest printing option.
- Regularly Clear Stored Data - Delete stored print jobs manually when possible. Ensure printer hard drives are encrypted, and always wipe or destroy storage before disposing of a printer.
- Protect Printers with Firewalls - Just like computers, printers need firewalls to block unauthorized access.
- Monitor Printer Activity - Have your IT team track printer logs to detect unusual print jobs, remote access attempts, or unauthorized printing. These are clear warning signs.
Printers Are More Than Just Office Devices—they're Security Threats
Many companies overlook printer security simply because they see printers as harmless equipment. But cybercriminals know these devices are often neglected, turning them into easy targets.
If you secure your computers but ignore your printers, you’re leaving a significant gap in your cybersecurity defenses.
