Why Cyber Attacks Often Start When Your Team Is Out of the Office
20 Apr 2026
Long weekends are meant for switching off.
Firing up the barbecue. Hitting the road. Spending time with family. Mentally checking out before you even leave the office.
But while you are winding down, someone else is gearing up.
And they are not planning a holiday.
Cyber criminals plan public holidays, weekends, and long breaks because they know one thing for sure; this is when businesses are at their quietest.
Holidays Are Not Random Targets
Attackers do not pick holiday weekends by accident.
According to Semperis’s 2025 Ransomware Holiday Risk Report, 52 percent of ransomware attacks happen on weekends or public holidays. That is not bad luck, it is deliberate timing.
They know that many small and medium businesses run on reduced staff. They know alerts are missed. They know logins are unchecked. They know the person who usually spots issues are already on the highway or at the campsite.
The real question is not whether businesses like yours are being targeted.
It is who is watching when it happens.
The Risk Starts Before the Weekend
The vulnerability does not begin on Friday afternoon.
It usually starts earlier in the week, when people begin to mentally check out.
By Wednesday, small shortcuts start creeping in. By Thursday, access is shared to get jobs done quickly. By Friday, systems are left logged in, laptops stay unlocked, and tidy up tasks are pushed to next week.
Common examples we see include:
- Shared logins so someone can finish a task quickly
- Temporary access given to vendors or contractors and never removed
- Open sessions left running as people rush to leave
- Final checks skipped because everyone is focused on getting out the door
None of this feels reckless at the moment. It feels normal.
But those small habits that quietly keep your systems secure during a regular week start to fall away, and they do not get revisited until Tuesday morning.
That creates a long window where no one is really paying attention.
The business did not go on holiday. The people did.
Who Is Actually Watching While You Are Away?
Here is where the imbalance really shows.
On one side, there are criminal groups who:
- Already know your software and systems
- Have tested your login pages
- Understand exactly when security coverage drops
- Treat this as a full time job
Semperis also found that 78 percent of organisations reduce security staffing by at least half during weekends and holidays. Attackers plan around this.
On the other side is most small businesses.
Often there is:
- A trusted IT contact
- A number you can call if something breaks
- Someone reliable when there is a problem
But they are not actively watching your systems at 2 am on a Saturday. They are not reviewing unusual login attempts. They are not monitoring strange network activity while you are away.
They are waiting for you to call.
And you cannot call if you do not know anything is wrong.
That gap, between proactive attackers and reactive support, is where real damage happens.
What Strong Coverage Actually Looks Like
Good security is not about reacting faster after something breaks.
It is about seeing issues before they turn into incidents.
With the right managed IT and security support in place:
- Systems are monitored around the clock, including weekends and public holidays
- Unusual behaviour is flagged early, such as logins from new locations or unexpected file activity
- Alerts go to a team that knows how to respond, not to an inbox that will not be checked until Tuesday
It also means preparing before the office empties out.
Simple steps like:
- Reviewing user access
- Removing credentials that are no longer needed
- Checking that systems are updated and monitored
- Making sure nothing temporary has become permanent by accident
Not because something is wrong, but because if something is wrong, you want to know before everyone leaves.
Security Is Tested in Silence
Cyber security is not tested when everyone is at their desk.
It is tested when no one is watching.
If your systems are monitored continuously, you are already ahead of where many businesses are. But if your approach is to wait until something breaks and then make a call, a long weekend is the worst time to rely on hope.
Attackers do not wait for obvious weaknesses. They wait for silence.
