On the surface, everything can look calm.
That is what makes Shark Week interesting every year. The danger is not what you see on top of the water. It is what is already moving underneath.
Cybercriminals work the same way.
The threats facing municipalities, public agencies, utility districts, libraries, parks departments, and public works teams are built to blend in. They look like normal emails, regular invoices, familiar contractors, Microsoft 365 password alerts, public records requests, or quick approvals from someone your staff already trusts.
Then money moves. Systems lock up. Citizen data gets exposed. Public services are disrupted. And by the time the problem is obvious, the damage may already be done.
Summer makes this worse.
People are traveling. Schedules are lighter. Department heads are out. Approval duties get handed off. Seasonal staff may be helping in parks, public works, or recreation. Attention gets split. Attackers know this, and they use it.
Here are three risks circling local government organizations across St. Louis, the Greater St. Louis region, and the Metro East right now.
1. Fake invoices and vendor impersonation
Attackers do not always need to hack your network.
Sometimes they only need to send one email that looks believable.
This is called business email compromise, or BEC. In the public sector, it happens when a criminal pretends to be a contractor, engineering firm, utility vendor, software provider, equipment supplier, grant partner, or internal leader your team already knows.
The email looks normal. The wording feels familiar. The request seems routine.
Someone pays the invoice, changes the ACH information, approves a transfer, or updates vendor records. Later, the real vendor calls asking about payment, and the agency finds out taxpayer dollars went to the wrong place.
These attacks increase during vacation season because the normal approval process often gets loose. The finance director may be out. A backup may not know what normal looks like. An urgent message may get treated as a problem to solve instead of a risk to verify.
This can happen in a city hall in Chesterfield, a utility district near St. Charles, a parks department in O’Fallon, or a public works office in Belleville. The target is not always the biggest agency. The target is often the one with the easiest process to exploit.
The fix is simple.
Create a verification process for any financial request that comes through email. If vendor payment details change, if wire or ACH information is sent, or if an invoice feels unusual, your team should confirm it using a known phone number. Not the phone number in the email.
A two-minute call can stop a very expensive mistake and protect public trust.
2. Phishing attacks aimed at distracted employees
Phishing works because people are busy.
That is the whole strategy.
An employee sees a Microsoft 365 password reset email and clicks the link. Someone gets a text that looks like it came from IT. A department head receives an urgent approval request right before a board meeting. A staff member opens a file because the email came from a name they recognize.
The attacker is counting on speed.
They want your people to react before they think.
For local governments, one compromised account can create a lot of problems. Email may contain citizen information, permit details, HR records, police or administrative communications, utility customer data, grant documents, financial records, or internal planning discussions.
Software matters, especially in Microsoft 365 environments. Multi-factor authentication, conditional access, email filtering, device management, and logging all matter. But the best protection is not only a tool. It is a culture where employees know they are allowed to slow down when something feels off.
Your team should pause when they see:
- An unexpected login request
- A payment instruction that came out of nowhere
- A link they were not expecting
- A message that creates pressure or urgency
- A request to bypass normal process
- A file share or document link that feels unusual
Speed is a weapon attackers use against your organization.
Slowing down takes that weapon away.
This matters whether you are serving residents in Clayton, Maryland Heights, Edwardsville, Collinsville, or any community across the region. Public agencies run on trust. A single compromised inbox can create confusion, downtime, and questions that no one wants to answer at the next council, board, or commission meeting.
3. Vendor and third-party access that is not being watched
Your organization may be secure, but what about the vendors connected to it?
If a vendor has access to your systems, data, email, cloud tools, finance platform, utility billing system, GIS data, camera systems, door access, backup tools, or citizen records, their problem can become your problem fast.
This is supply chain risk.
Most public agencies have more of it than they realize.
Think about all the software tools your organization uses. Think about outside IT providers, auditors, engineering firms, payroll vendors, permitting platforms, payment processors, public safety systems, website vendors, and contractors with credentials. Think about project-based users who had access during a rollout. Think about old accounts that were never removed.
Each one can become a path into your organization if it is not managed.
Outsourcing a service does not outsource responsibility.
You need to know the basics:
- Which vendors can access your data or systems?
- What exactly are they connected to?
- Who inside your organization is responsible for that relationship?
- When was their access last reviewed?
- What happens when the contract, project, or employee relationship ends?
If those answers are not clear, your risk is not clear either.
And unclear risk is where problems start.
This is also where strategic technology planning matters. Cybersecurity is not just an IT checklist. It connects to budgeting, procurement, continuity of operations, insurance, records retention, public communication, and emergency response. If a system goes down, residents still expect services to continue. They still need permits processed, bills paid, water service supported, parks scheduled, and library systems available.
By the time you see the threat, it may already be moving
Sharks do not announce themselves.
Neither do the cybercriminals targeting local government.
The agencies that get hit are not always ignoring obvious warning signs. Many believe everything is fine because nothing looks wrong on the surface.
That is the trap.
Invoices look normal. Vendor access looks routine. Microsoft 365 alerts look familiar. Employees are just trying to serve the public. Summer schedules feel relaxed.
Meanwhile, attackers are looking for the gap.
At Tigerhawk, we help municipalities, public agencies, utility districts, libraries, parks departments, public works teams, and economic development organizations get a clear picture of where they are exposed across people, vendors, email, devices, Microsoft 365, and daily operations. Not with scare tactics. With practical steps that make sense for real public service environments.
If you are not sure where your organization stands, now is a good time to find out.
