Every summer, Shark Week reminds us of something worth remembering the rest of the year too: the danger is almost never visible on the surface. It's what's already circling underneath. Cybercriminals work exactly the same way. The threats facing businesses right now are built to blend in with normal, everyday operations until the moment something breaks, money moves, or systems go down. And during the summer, when schedules shift, employees travel, and oversight naturally gets thinner, attackers know Houston businesses are paying a little less attention. Here are three of the ways they're circling right now.
1. Fake Invoices and Vendor Impersonation
Attackers often don't need to hack anything at all. In many cases, all it takes is one believable email. This tactic is called business email compromise, or BEC, and it works by impersonating a vendor, supplier, or executive your team already knows and trusts.
The email arrives looking completely routine. Someone on your team pays the "vendor." By the time anyone realizes the request wasn't legitimate, the money is already gone.
These attacks spike during vacation season for a simple reason. When the person who normally approves payments is out of the office, requests get rerouted to people who don't always know what a normal request looks like. A temporary stand-in is far less likely to question urgency, and attackers count on exactly that.
The fix is simple to put in place: Build a verification step for any financial request that comes in by email. A quick confirmation call to a known number, not the number printed in the email itself, is usually enough to stop these before they go anywhere.
2. Phishing That Targets Distracted Employees
Phishing works because it's engineered around how people behave when they're busy. Cybercriminals design these moments deliberately. A distracted employee sees a password reset notification and clicks the link. Someone gets a text that looks like it came from IT. An email lands right before a meeting asking for urgent approval on a wire transfer. Nobody stops to verify, because stopping feels like losing time.
The most effective protection here isn't a piece of software. It's culture. Your team needs to feel genuinely comfortable slowing down when something seems off, whether that's:
- An unexpected login or password reset request
- A payment instruction that came out of nowhere
- A link in an email nobody was expecting
3. Third-Party Risks That Travel Fast
When a vendor with access to your systems gets compromised, the threat doesn't stay politely contained to them. It travels straight into your environment through whatever connection they have to your business.
This is supply chain exposure, and most Houston businesses have far more of it than they realize. Software tools connected to your network, service providers holding your credentials, and contractors whose access was never removed after a project wrapped up all create a path most business owners have never actually mapped out.
Outsourcing a service doesn't outsource the accountability that comes with it. Knowing where you stand means being able to answer three questions:
- Which vendors can currently access your data or systems?
- What exactly are they connecting to?
- Who inside your business is responsible for managing those relationships?
If those answers aren't clear, that gap is quietly opening you up to risk.
By the Time You See It, It's Already Moving
Sharks don't announce themselves, and neither do the cybercriminals targeting your business right now. The companies that get hit usually aren't the ones ignoring obvious warning signs. They're the ones who assumed everything was fine because nothing looked wrong.
Summer is when schedules loosen, attention drifts, and the water looks calmest. It's also when attackers are most active.
The calm surface is exactly what they're counting on.
