When you think about cybersecurity threats, your office printer probably doesn’t top the list. But it should.

Hackers love printers. In a 2020 experiment by Cybernews, 56% of 50,000 printers were compromised—nearly 28,000 devices printing out warnings because businesses ignored this unassuming security risk.

 

Why Hackers Target Printers
Printers are data goldmines. They handle payroll, contracts, and client info—yet most are left wide open. Here’s how hackers exploit them:

  • Stored Data Exposure: Many printers store digital copies of every print, scan, or copy. If compromised, hackers can reprint sensitive files.
  • Default Admin Credentials: Manufacturers often ship printers with weak default passwords like “admin/admin.” When left unchanged, they’re an easy target.
  • Network Access: Once breached, a printer can become a gateway to your entire network, spreading malware or intercepting data.
  • Unencrypted Print Jobs: If print jobs aren’t encrypted, hackers can intercept documents—exposing contracts, medical records, or confidential reports.
  • Outdated Firmware: Regular updates are rare, leaving printers vulnerable to known exploits.

 

How To Safeguard Your Printer
Now that you know the risks, here’s what to do:

  1. Change Default Passwords: Immediately update to strong, unique credentials.
  2. Install Firmware Updates: Regularly check for and apply security patches.
  3. Encrypt Print Jobs: Use secure print settings to protect documents in transit.
  4. Limit Access: Restrict printing to authorized users and use PIN codes when possible.
  5. Clear Stored Data Regularly: Wipe printer storage periodically, especially before disposal.
  6. Monitor Activity: Keep an eye on print logs for unusual or unauthorized jobs.
