October is Cybersecurity Awareness Month. For accounting firms, CPA practices, tax professionals, bookkeepers, payroll providers, and financial service organizations, it is a good time to take a closer look at what you know, what you assume, and what is actually protecting your firm.
Not all cybersecurity advice is accurate. Some advice has been repeated for so long that it sounds like fact, even when it is outdated or incomplete.
That creates blind spots. Cybercriminals look for those blind spots, especially in firms that handle client financial data, payroll records, tax documents, financial statements, and access to bookkeeping systems. During tax season, one exposed account, one missed update, or one bad click can create a serious problem.
The good news is that these gaps are usually simple to address once you know where to look. Here are six cybersecurity myths we hear from accounting and financial service organizations in Hannibal, Marion County, and across Northeast Missouri, along with the facts behind them.
Myth 1: We are too small for cybercriminals to care about
There is no accounting firm too small for an opportunistic cybercriminal. It does not matter if you are a solo tax preparer, a bookkeeping office with a few employees, or a larger CPA firm serving clients across the Tri-State area.
If you have exposed accounts, client financial data, access to payroll systems, payment information, or vulnerable devices, you may be a target. Your firm could also provide an entry point into a client, vendor, bank, or payroll platform.
Fact: Hackers choose targets based on opportunity, not firm size.
Myth 2: Employees will recognize a phishing email
The obvious phishing emails filled with typos and suspicious senders are not the only threat anymore. Many scams are polished, personalized, and designed to look like they came from someone you trust.
That matters in accounting. A fake message may look like it came from a client sending tax forms, a business owner asking to update payroll direct deposit, a bank requesting verification, or a software vendor asking your team to log in.
Artificial intelligence has made it harder to spot a scam by reading the message alone. Your team also needs to look at the behavior behind the request.
Ask whether the supposed sender would:
- Send tax documents through an unusual method
- Change payroll or payment instructions unexpectedly
- Request client financial data or financial statements without context
- Send a new or unusual login link for a bookkeeping, tax, or payroll system
If something feels unusual, slow down and verify it through a separate channel. Call the person using a known phone number. Do not reply to the message or use the contact information it provides.
Fact: A convincing email can still be a scam.
Myth 3: MFA fully protects our accounts
Multi-factor authentication is an important layer of protection, but it is not invulnerable. Criminals use MFA fatigue attacks to take advantage of employees who receive repeated approval requests.
For example, prompt bombing can flood a phone with login requests. The attacker hopes the employee eventually approves one just to make the notifications stop.
For CPA firms and bookkeeping teams, this matters because one compromised account can expose tax software, cloud storage, email, payroll records, financial statements, and client portals.
MFA should be supported by strong passwords, managed devices, access controls, security awareness training, and monitoring. Where possible, use phishing-resistant authentication methods instead of relying only on approval notifications or text messages.
Fact: MFA should be part of a broader security strategy.
Myth 4: Our backups have us covered
Ask yourself a practical question. If ransomware locked up your files tomorrow, could your firm restore its data? How long would that take, especially during tax season or payroll processing week?
A backup only helps when it is available, protected, and tested. Many firms discover during an incident that backups were incomplete, connected to the network, too old, or impossible to restore quickly.
For accounting firms, the details matter. Can you recover tax workpapers, bookkeeping files, payroll records, scanned source documents, financial statements, client communications, and firm operations data? Can you prove the backup worked before you need it?
Review your backup schedule, retention periods, access controls, and recovery process. Test the process regularly so you know what will happen before there is a crisis.
Fact: Having backups is not the same as being able to recover.
Myth 5: Cybersecurity is only IT responsibility
Your IT team or technology provider does a lot to protect your systems. They cannot control every click, password, file transfer, portal invitation, or payroll change request made by employees.
Cybersecurity decisions happen throughout your firm. A single bad click can open the door to malware, stolen credentials, fraudulent payroll changes, or unauthorized access to client financial data.
Security awareness training helps employees recognize unusual requests and know when to ask for help. The goal is not to make everyone a technical expert. The goal is to help people make safer decisions during a busy workday, especially when deadlines are tight and tax season pressure is high.
Fact: Training employees to make good decisions strengthens your cybersecurity.
Myth 6: We know what to do if something happens
Imagine it is Tuesday morning in the middle of filing season and several employees suddenly cannot access tax files, bookkeeping systems, payroll records, or client portals. That is when many firms discover they have not answered a few basic questions.
- Should employees shut down their computers?
- Who contacts IT or your technology provider?
- What happens if email and phone systems are unavailable?
- When should your cyber insurance company be involved?
- Who communicates with clients, banks, vendors, and payroll contacts?
- How will employees receive updates?
- How will time-sensitive tax, payroll, and financial reporting deadlines be handled?
Do not rely on memory during an incident. Create a written incident response plan, assign responsibilities, and test the plan with your team. Your response process should also include backup communication methods and a clear escalation path.
For firms in America’s Hometown and across Marion County, business continuity is not just an IT issue. It is how you keep serving clients when systems, files, or communication channels are interrupted.
Fact: Your recovery plan should not debut during an incident.
Cybersecurity awareness starts with the facts
Cybersecurity Awareness Month is a good reminder to check the assumptions guiding your decisions.
Myths are comfortable. They can make you feel protected without requiring you to look closely at the details. But many cybersecurity gaps come from believing everything is handled when it is not.
At Tigerhawk Technologies, we help local organizations separate real protection from false confidence. For accounting firms and financial service organizations, that starts with understanding your accounts, devices, backups, policies, bookkeeping systems, payroll access, client data, and response plans.
If any of these myths sound familiar, take a closer look at where your firm stands. Schedule a discovery call and let us help you identify the practical steps that can reduce your risk.
Questions Hannibal accounting teams ask us
What cybersecurity basics should a Hannibal CPA firm have in place before tax season?
Start with protected email, multi-factor authentication, strong password management, endpoint security, tested backups, and clear access controls for tax software, client portals, and shared files. Then train your team on phishing and unusual client requests. Before tax season, also confirm who handles incident response, client communication, and recovery decisions if systems go down.
How should bookkeepers and payroll providers in Northeast Missouri protect payroll records and client financial data?
Payroll and bookkeeping data should be limited to the people who truly need access, protected with multi-factor authentication, and stored in secure systems rather than personal email or unmanaged devices. Changes to direct deposit, vendor payments, or financial records should be verified through a known phone number. Regular backups and audit logs are also important.
Do accounting firms in the Hannibal and Tri-State area need a written business continuity plan?
Yes. A written business continuity plan helps your firm keep moving if tax software, email, payroll platforms, internet service, or file access is interrupted. It should identify critical deadlines, backup communication methods, recovery priorities, vendor contacts, and employee responsibilities. The plan does not need to be complicated, but it should be documented and tested.
