While your team was enjoying the Bank Holiday weekend, somewhere out there an automated attack was scanning thousands of UK business networks for a way in. No human required.
There's a persistent myth about cyber attacks that needs putting to rest. The image of a lone hacker, hunched over a keyboard in a dark room, manually breaking into businesses one by one. It's outdated. It's been outdated for years. And clinging to it is leaving businesses dangerously exposed.
The reality in 2026 is that cyber attacks are automated, industrialised, and relentless. And bank holidays, like the one the UK just had on 25th May, are prime time for cyber attacks to take place.
Think about what happens when a bank holiday hits. Staff log off. IT teams are on skeleton cover or none at all. Nobody is monitoring inboxes, flagging suspicious activity, or picking up the phone to report something odd. The business is effectively unattended.
Attackers know this. They plan for it. And with modern AI-powered tools, they don't need to be sitting at a computer themselves, they simply set their automated systems running and let them work through the long weekend while everyone else is at a barbecue.
"It's no longer a lone hacker at a keyboard. It's automated systems running 24 hours a day, scanning thousands of businesses simultaneously, looking for the one that left a door unlocked."
Modern cyber attacks don't require expertise to launch — they require tools, and those tools are widely available. Here's what's happening to UK businesses right now, at scale, around the clock:
Phishing at scale
AI generates thousands of convincing, personalised phishing emails in seconds. Your staff get back from holiday to a full inbox and one of those emails looks completely legitimate.
The good news is that the vast majority of successful attacks exploit preventable weaknesses. Businesses that take the basics seriously are dramatically harder to breach than those that don't and the basics are not as complicated or expensive as many assume.
The most important things to address are the ones attackers look for first: Microsoft 365 configurations that haven't been reviewed, accounts with weak or absent multi-factor authentication, former employees whose access was never removed, and networks with no active monitoring in place.
A business that has its fundamentals right, properly configured systems, active monitoring, and a team that knows what to do when something looks wrong is not an easy target. Attackers move on to easier prey.
The question to ask yourself is simple: if an attack started on a bank holiday Friday evening, how long would it be before anyone noticed?
