Is Your Printer The Biggest Security Threat In Your Office?

If I asked you to identify the major cybersecurity threats in your office, you might mention phishing emails, malware, or weak passwords. However, what if I told you that your office printer, the one quietly humming in the corner, could be one of the most significant vulnerabilities in your entire network?

It may sound absurd, but hackers have a keen interest in printers. Many businesses are unaware of the security risks they pose until it's too late. In 2020, Cybernews conducted what they termed the "Printer Hack Experiment." From a sample of 50,000 devices, they successfully compromised 56% of the printers, prompting them to print a sheet on printer security. This amounts to nearly 28,000 compromised devices, all due to businesses underestimating this seemingly innocuous piece of office equipment.

Why Target Printers?

Printers are a treasure trove of sensitive data. They handle everything from payroll documents and contracts to confidential client information. Yet, many businesses leave them vulnerable to attacks.

Here's what can occur when a hacker accesses your printer:

• Printers store sensitive data - Each time you print, scan, or copy a document, your printer retains a digital copy. Many printers have built-in hard drives that can store years' worth of documents, including payroll files, contracts, and employee records. A hacker gaining access can steal or even reprint those files without your awareness.
• Default passwords are a hacker's dream - Most printers come with default admin logins like "admin/admin" or "123456." Many businesses fail to change these, making it incredibly easy for cybercriminals to take control.
• They're an open door to your network - Printers connect to your WiFi and company network. If compromised, they can serve as an entry point to install malware or ransomware or steal data from other devices.
• Print jobs can be intercepted - If your print jobs lack encryption, hackers can intercept documents before they reach the printer. This means confidential contracts, legal documents, and even medical records could be exposed.
• They can spy on your business - Many modern printers have built-in storage and scan-to-email features. If a hacker compromises your device, they can remotely access scanned documents, emails, and stored files.
• Outdated firmware leaves the door wide open - Like any device, printers require security updates. However, most businesses neglect to update their printers' firmware, leaving them vulnerable to known exploits.
• Data mining from discarded printers - Improperly disposed printers can be a goldmine for cybercriminals. Residual data on discarded printers can be mined for sensitive information, leading to potential security breaches. Printers must have their storage wiped clean to prevent vulnerabilities and legal liabilities.

How To Protect Your Printers From Hackers

Now that you understand the risks associated with printers, here's what you should do right away:

• Change The Default Password - If your printer still uses the default login credentials, change them immediately. Use a strong, unique password similar to what you would use for your email or bank account.
• Update Your Printer's Firmware - Manufacturers release security patches for a reason. Log into your printer settings and check for updates, or have your IT team handle this.
• Encrypt Print Jobs - Enable Secure Print and end-to-end encryption to safeguard against hackers intercepting print jobs.
• Restrict Who Can Print - Implement access controls so only authorized employees can send print jobs. If your printer supports PIN codes, require them for sensitive print jobs. You can also offer a guest option.
• Regularly Clear Stored Data - Some printers allow you to manually delete stored print jobs. If yours has a hard drive, ensure it's encrypted, and if you replace a printer, wipe or destroy the hard drive before disposal.
• Put Your Printer Behind A Firewall - Just like computers, printers should be protected by a firewall to prevent unauthorized access.
• Monitor Printer Activity - If your IT team isn't already tracking printer logs, now is the time to start. Unusual print activity, remote access attempts, or unauthorized users printing sensitive documents should raise red flags.

Printers Aren't Just Office Equipment - They're Security Risks

Many businesses fail to take printer security seriously because they view printers as mere office equipment. However, cybercriminals recognize that these devices are often overlooked, making them easy targets.

If you're safeguarding your computers but neglecting your printers, you're leaving a significant gap in your cybersecurity defenses.
