It Looked Normal… That Was the Problem”
Yesterday, I shared a scenario where one click led to a full compromise.
Let’s break down what actually went wrong.
- The email didn’t look suspicious. Attackers no longer rely on obvious phishing. They mimic normal business processes — document reviews, invoices, internal requests.
- There was no immediate alert. Most SIEM systems don’t trigger on a single login event, especially if it looks like normal user behaviour.
- Credentials were the real target. Once login details were entered, the attacker didn’t “hack” anything.
They logged in.
- The attack was slow and quiet. No noise. No crash. No obvious breach.
Just movement inside the network.
This is the gap many organisations miss:
Security tools are built to detect anomalies.
But human behaviour often looks… normal.
That’s why awareness training needs to evolve.
Not just: “Don’t click suspicious links.”
But: “How do attackers make normal look safe?”
What would you expect your SIEM to catch in this situation?
