A Wi-Fi Warning: How One Community Management Company’s Printer Let Down Its Guard and Let Fraudsters In

Wi-Fi is an everyday convenience for communication. But without strong cybersecurity measures, your Wi-Fi network is like an unlocked front door: anyone can come in and make themselves at home.

The 2026 Wireless Broadband Alliance Industry Report notes that “Wi-Fi has become essential infrastructure” for companies around the world. Yet the Pew Research Center reports that only 21% of Americans regularly monitor and update their Wi-Fi network security settings. That oversight can make Wi-Fi an easy entry point for cybercriminals.

One Western Alliance Bank client learned that the hard way when a printer’s unchanged manufacturer Wi-Fi password almost became a costly lesson.

A Real-Life Example of Wi-Fi Fraud Risk

Imagine walking into your office and finding a stack of printouts bearing an ominous threat from a stranger.

That’s how one community association manager started their workday. They came into the office and found a 100-page ransom letter waiting on their printer saying things like, “if you’re reading this it means the internal infrastructure of your company is fully or partially dead” and “if you fail to cooperate, we will sell personal information, trade secrets, databases and code sources to the dark market”.

Cybercriminals had broken in through the printer’s Wi-Fi address and demanded payment to release access to the company’s financial information.

In this case, the threat was only a scam and did not have any real vital information about the company. But the company lost a day to evaluating the threat and updating its systems – and the case offers an important warning to any business that uses Wi-Fi.

How Can a Wi-Fi Password Expose Your Business?

Many device manufacturers provide default passwords to allow users to set up new Wi-Fi networks or add new devices to existing networks. In this case, the printer was still operating with the original Wi-Fi password provided by the supplier. That left the device vulnerable to anyone in the vicinity who knew the manufacturer’s standard passwords.

With just a few quick steps, these would-be cybercriminals sent the ransom note directly via the office printer, creating the illusion that they had full access to the company’s system.

What Should You Do If You Suspect a Wi-Fi Security Breach? 

The quick-thinking business owner took immediate action. The first call was to an IT company. The next call? Their Western Alliance relationship manager.

The IT company quickly evaluated the situation and determined that these bad actors were unable to access the business’s financial information through the printer’s Wi-Fi network. The company strengthened and updated its passwords and security settings to elevate its existing network protections.

Although no financial information appeared to have been compromised, the Western Alliance team worked with the client to take extra steps. The banking team and client carefully reviewed all incoming and outgoing transactions, changed bank account numbers to remove any connection to potentially compromised data and thoroughly reviewed the management company’s fraud protection services on their business accounts.

Fortunately, the company’s data was safe. But taking these measures cost the business an entire day of work – and offered an eye-opening view into what could have been.

How Can You Prevent Wi-Fi Security Risks?

As fast as technology is evolving, so are bad actors who take advantage of weaknesses in network security. Staying current with the latest cybersecurity innovations is a business imperative.

Strong cybersecurity measures encompass more than technology. In addition to changing default passwords, implementing two-factor password authentication and conducting ongoing employee education, here are a few simple ways to elevate your business’s cyber defenses:

• Avoid Wi-Fi hotspots in the airport or coffee shop – they’re convenient, but risky.
• Regularly back up critical data and store it in separate locations.
• Protect your business and smartphone from cybersecurity attacks.
• Carefully review requests for data and flag if they seem suspicious.
• Review financial statements for inconsistencies and unexplained activity.
• Regularly update and scan for system updates, gaps in protection and potential threats.
• Use and regularly update antivirus/anti-financial malware solutions appropriate for your business.

In addition to these precautions, another thing to consider could be to evaluate purchasing cybersecurity insurance to cover everything from ransomware demands and data restoration to business interruption losses and customer notification costs. But remember, insurance only covers true losses. Without an up-to-date cybersecurity strategy, you might still be liable for any damages an insurer deems due to your own negligence.
