When you're headed to the cookout or crawling through holiday traffic, cybercriminals are already getting to work.
They've done the planning. They know which businesses will be short-staffed, which inboxes will sit unchecked, and which alerts are likely to go unanswered.
They also know that in many small businesses, the so-called "IT person" is usually the one who resets passwords, fixes printers, and gets called only after something has already gone wrong—not someone actively watching security systems at midnight. And they know that from Friday afternoon to Tuesday morning, there can be 72 hours of near-total quiet.
Attackers are looking forward to Memorial Day, too—but for very different reasons.
According to Semperis's 2025 Ransomware Holiday Risk Report, 52% of organizations hit by ransomware were attacked during a holiday or weekend. That isn't random. It's intentional.
The real issue isn't whether your business could be targeted over a holiday weekend.
The real question is: who is watching when it happens?
The 48-hour exposure window
The risk doesn't begin when the weekend starts. It begins the moment people start mentally signing off.
For many teams, that starts around Wednesday.
By Thursday afternoon, little shortcuts begin to appear. Someone shares a login because a coworker needs fast access and IT isn't available to set it up properly. A vendor gets temporary credentials that never get recorded. A contractor wraps up a project, but their access stays open because the person responsible is already out the door.
By Friday, the cracks widen. Sessions remain open. Laptops go unlocked. The everyday habits that quietly protect a business during the workweek start to disappear as everyone rushes to finish and leave.
None of it feels dangerous in the moment. It feels routine. But those "routine" decisions often aren't reviewed until Tuesday morning. By then, attackers may have had hours—or days—of uninterrupted access.
The business didn't leave for the weekend. Your people did.
Who is really on duty?
Here's the disconnect many small businesses don't see until it's too late.
On one side, there's a criminal group that has already done the homework. They know your software stack. They've tested your sign-in pages. They're waiting for a quiet opening. This is their full-time job, and they're very good at it. Semperis found that 78% of companies cut security staffing by at least half on weekends and holidays. Attackers count on that.
On the other side, who is actually monitoring?
For many small businesses, the honest answer is no one. Or it's a phone number for the IT person you call when something breaks.
But they aren't watching your systems at midnight on Saturday. They aren't spotting a login from an unusual location at 2 a.m. They aren't reviewing suspicious network activity while you're at the beach. They're waiting for you to report a problem—and you can't report what you don't know is happening.
That's the gap: a reactive setup going against a proactive threat. That's not a fair fight.
What it looks like when security is truly balanced
A managed service provider does more than repair systems after something fails.
In a stronger model, monitoring runs 24/7—whether it's Thursday afternoon or the middle of a holiday weekend. Unusual behavior gets flagged early: a login from a new location, a file transfer that doesn't match normal patterns, or an access attempt on a system that should be dormant. Those alerts reach a team trained to respond, not a voicemail box that won't be checked until Tuesday.
It also means preparing before the weekend begins. Reviewing access. Confirming credentials. Making sure you know exactly who can get into what—and whether anything needs to be cleaned up before the office empties out.
Not because there's already a problem, but because if one appears, you want to catch it before everyone leaves—not after they return.
Security isn't proven when systems fail. It's proven when nobody is looking.
You may already be in solid shape. If someone is truly watching your systems around the clock, you're ahead of most businesses.
But if your plan is to wait for a break-fix moment and then make a call, it may be time to rethink that strategy before the next long weekend arrives.

And if you know a business owner heading into a long weekend with nothing protecting their company from a professional criminal operation except hope, send this along.
Attackers don't wait for weakness. They wait for silence.
