When you think of major cybersecurity risks in your workplace, you might first mention phishing emails, malware, or weak passwords. But what if I told you that your office printer—the quiet device in the corner—could actually be one of the most vulnerable points in your entire network?
It may sound surprising, but hackers actively target printers. Many companies don't realize the extent of this threat until it's too late. In 2020, Cybernews conducted a "Printer Hack Experiment," where they tested 50,000 devices and successfully breached 56%—that's nearly 28,000 printers compromised—forcing them to print a security awareness message. This reveals how often businesses underestimate the risks posed by 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 exposed and vulnerable.
Here’s what can happen if a hacker gains control of your printer:
● Printers store confidential data - Every print, scan, or copy job is often saved digitally. Many printers come with built-in hard drives that retain years of documents including payroll files, contracts, and employee records. If breached, attackers can steal or reproduce these files without your knowledge.
● Default passwords make hacking easy - Most printers are shipped with default admin credentials like "admin/admin" or "123456". Unfortunately, many businesses never change these, allowing cybercriminals effortless access.
● Printers serve as gateways to your network - Connected to your WiFi and company network, compromised printers can be exploited to deploy malware, ransomware, or to steal data from other devices.
● Print jobs can be intercepted - Without encryption, hackers can intercept documents mid-transmission, exposing confidential contracts, legal files, and medical records.
● They can spy on your operations - Modern printers often include storage and scan-to-email features. If compromised, attackers can remotely access scanned documents, emails, and stored files.
● Outdated firmware creates vulnerabilities - Like any device, printers require regular security updates. Many businesses neglect firmware updates, leaving their devices exposed to known exploits.
● Data mining from discarded printers - Improperly disposed printers can reveal sensitive data to cybercriminals. It’s essential to securely erase all storage before disposal to prevent data breaches and legal risks.
Essential Steps to Secure Your Printers Against Hackers
Now that you understand the risks, take these immediate actions to protect your printers:
- Change Default Passwords - Replace factory-set login credentials with strong, unique passwords just as you would for your email or banking accounts.
- Update Firmware Regularly - Manufacturers release updates to patch vulnerabilities. Check your printer’s settings or have your IT team ensure firmware stays current.
- Encrypt Print Jobs - Activate Secure Print and end-to-end encryption features to block interception of sensitive documents.
- Restrict Printing Access - Implement access controls so only authorized personnel can print. Use PIN codes for sensitive jobs and provide guest options if needed.
- Clear Stored Data Frequently - Manually delete stored print jobs where possible. Ensure any printer hard drives are encrypted, and securely wipe or destroy drives before disposal.
- Protect Printers with Firewalls - Just like computers, printers should be shielded by a firewall to block unauthorized access.
- Monitor Printer Activity - Have your IT team track printer logs closely. Look out for unusual print jobs, remote access attempts, or unauthorized usage as warning signs.
Printers Are More Than Just Office Devices – They’re Critical Security Risks
Many companies overlook printer security simply because they see them as basic office tools. However, cybercriminals exploit this oversight, making printers an easy and often overlooked target.
If you’re securing your computers but neglecting your printers, you’re leaving a significant gap in your cybersecurity defenses.
