When it comes to cyber-attacks, timing is rarely accidental. And yet every summer, schools and universities are caught off guard; systems are breached, data is locked, plans are disrupted, right as staff begin to switch off. It’s a pattern that’s hard to ignore. These aren’t just unfortunate coincidences. They’re calculated moves by attackers who understand when we’re most exposed, when the lights are on but no one’s watching. The summer break has quietly become peak season for targeting education. The evidence is mounting, and the strategy is clear: hit hard when defences are thin, response times are slow, and the attack surface is quietly expanding in the background.
Let’s take a closer look.
When you look at the data, it’s clear that summer is when attackers like to strike universities and schools. As reported:
That’s not random, that’s a strategy.
The logic behind these attacks is simple, and it’s being repeated with precision. The same conditions that make summer a welcome break for staff also make it a golden window for attackers.
Here’s how it plays out:
Once the target has been identified, attackers deploy ransomware or exfiltrate data, often just before the new term begins, when the damage is hardest to undo - everyone just wants the problem to go away, so they are more willing to pay the ransom.
The result? Maximum disruption, minimal resistance.
So can we stop this? Not necessarily, and this is where the non-technical aspects of the threat start to kick in. Many universities still allow external DNS lookups or have dormant services exposed externally. Even if you patch for one exploit, the next variation will bypass it.
And if I’m an attacker? I don’t need a zero-day. I just need timing. I can plant content on an internal LDAP server in June, then trigger it in August when the SOC is under-resourced and the term hasn’t started yet.
The best defences combine people, process and technology. That means:
At Hexiosec, we’re helping organisations prepare for these threat patterns, not just react to them. We conduct the National Picture of Risk for universities and a number of government departments so that you can stay ahead of the threats, and hopefully enjoy your summer holidays undisturbed.
