While you’re firing up the grill or sitting in beach traffic, someone else is getting to work.
They’ve been planning for this.
They know which businesses will be running on skeleton crews. They know which alerts will go unanswered. They know that at most small businesses, the “IT person” is whoever gets called when the printer breaks — not someone watching a security dashboard at midnight. And they know that the window between Friday afternoon and Tuesday morning is 72 hours of quiet.
They’ve been looking forward to Memorial Day, too. Just not for the same reasons you are.
According to Semperis’s 2025 Ransomware Holiday Risk Report, 52% of organizations hit by ransomware were attacked on a holiday or weekend. That’s not a coincidence. That’s a strategy. And CISA’s ransomware guidance makes clear that threat actors deliberately time attacks for when defenses are thinnest — because it works.
The question isn’t whether someone is targeting businesses like yours over a holiday weekend.
The question is: who’s watching when it happens?
The 48-Hour Window
The vulnerability doesn’t start when the weekend begins. It starts when people mentally check out.
That’s usually around Wednesday.
By Thursday afternoon, small shortcuts start creeping in. Someone shares a login because a coworker needs quick access and IT isn’t around to set it up properly. A vendor gets temporary credentials nobody documents. A contractor finishes a project, but their access never gets removed because the person responsible is already on the road.
Friday is where things really start to slip. Sessions stay open. Laptops don’t get locked. The small habits that quietly keep systems secure during a normal week — the ones nobody thinks about because they’re just routine — start falling off as everyone rushes out the door.
None of it feels reckless. It feels normal. But those “normal” decisions don’t get revisited until Tuesday morning. And by then, there’s been a long window where nobody was paying attention.
The business didn’t leave for the weekend. The people did.
Who’s Working While You’re Away
Here’s the mismatch most small businesses don’t think about until it’s too late.
On one side, there’s a criminal operation that has already done its homework. They know your software stack. They’ve tested your login pages. They’re waiting for a quiet moment to move. This is their job, and they’re good at it. Semperis found that 78% of companies reduce security staffing by at least half during weekends and holidays. Attackers know this. They plan around it.
On the other side: who’s there?
For most small businesses, the honest answer is no one. Or there’s a phone number — a reliable IT person you can call when something breaks. But they’re not watching your systems at midnight on a Saturday. They’re not seeing a login attempt from an unusual location at 2 AM. They’re not catching strange network traffic while you’re at the beach.
They’re waiting for you to call. And you can’t call if you don’t know anything is wrong.
That’s the gap. Not just thinner defenses — but a reactive model going up against a proactive one. The SBA puts it plainly: small businesses are high-value targets precisely because attackers expect them to be underprepared. That’s not even a fair match.
What It Looks Like When Someone Actually Is Watching
Here’s what changes when you have real monitoring in place instead of a phone number you hope to never dial.
Monitoring runs continuously — whether it’s a Thursday afternoon or the middle of a holiday weekend. Systems flag unusual behavior early, things like:
- A login attempt from a location your team has never accessed from before
- A file transfer that doesn’t match normal business hours or patterns
- An access attempt on a system that shouldn’t be active at all
- Credential use from an account that belongs to someone who left six months ago
Those alerts go to a team that knows what to do with them — not to a voicemail that won’t get checked until Tuesday.
It also means doing the preparation before the weekend starts. Reviewing who has access to what. Cleaning up credentials that should have been removed months ago. Making sure there’s a clear picture of your systems before the office empties out.
Not because something is wrong. But because if something is, you want to know before everyone leaves — not after they come back.
This is the difference between in-house IT and working with a managed security services provider. In-house IT responds to problems. A managed service provider is actively looking for them — around the clock, including holidays, including the quiet Saturday night when no one else is paying attention. CISA’s cybersecurity best practices consistently point to continuous monitoring as one of the most effective defenses available to organizations of any size.
Security isn’t tested when something breaks. It’s tested when no one is watching.
FAQ
Why are businesses more vulnerable to cyberattacks on holidays?
Attackers are opportunists. They know that holiday weekends mean reduced staffing, slower response times, and more open windows — both literally and digitally. The same Semperis research that found 52% of ransomware attacks hit on a holiday or weekend also found that most companies cut security staffing by at least half during those periods. That math works out well for the attacker, not the business owner.
What is ransomware and how does it work?
Ransomware is malicious software that locks you out of your own systems — your files, your data, sometimes your entire network — and demands payment to restore access. Attackers usually get in through phishing emails, stolen credentials, or unpatched software. Once they’re inside, they can move quietly through your systems for days before triggering the actual attack. By the time you see the ransom message, they’ve often already done serious damage.
How do I protect my business from ransomware over a holiday weekend?
A few things make a real difference. First, make sure access is cleaned up before the weekend — remove credentials for people who no longer need them. Second, have someone actually monitoring your systems, not just a break-fix contact waiting for your call. Third, confirm your backups are current and tested. And fourth, make sure your team knows what a phishing attempt looks like before they leave for the holiday, not after they get back.
What does a managed service provider do for cybersecurity?
A managed service provider — particularly one focused on security — monitors your systems continuously, flags suspicious activity in real time, and responds to threats before they become disasters. The difference between an MSP and a traditional IT setup isn’t just the technology. It’s the posture. Break-fix IT waits for the call. A good MSP is already watching so you don’t have to make one.
How do I know if my business has been hacked?
Often, you don’t — at least not right away. That’s what makes it dangerous. Warning signs include slow systems with no clear cause, employees getting locked out of accounts, unfamiliar devices showing up on the network, or unusual file activity. But many breaches go undetected for weeks. That’s exactly why continuous monitoring matters: by the time the symptoms are obvious, the window to contain the damage has often already closed.
You may already be in good shape here. If someone’s monitoring your systems around the clock, you’re ahead of where most businesses are.
But if your current plan is to wait until something breaks and then make a call, it’s worth rethinking before the next long weekend rolls around.

And if you know a business owner heading into a long weekend with nothing between their company and a professional criminal operation except hope — send this their way.
Because attackers don’t wait for weaknesses. They wait for silence.
