The email shows up on a Tuesday morning.
It looks like it’s from the CEO. The name matches. The tone is right. Even the signature looks familiar.
“Hey, can you help me with something quickly? I’m in back-to-back meetings. Need you to handle a vendor payment. I’ll explain later.”
The new employee pauses.
They’ve been with the company for four days. They’re still figuring out how things work. They don’t know what’s normal yet, and they definitely don’t want to be the person who questions the CEO in their first week.
So, they go ahead and help.
And just like that, the damage is done.
In high-trust environments, whether it’s a financial institution handling member transactions, a healthcare clinic coordinating patient care, or a professional services firm managing sensitive client data, this kind of mistake doesn’t stay small for long. These organizations operate more like small emergency rooms: constant demand, fast decisions, and very little room for error.
Why is the first week the most dangerous week?
Every spring, businesses bring in a new wave of employees largely made up of recent graduates and summer interns stepping into their first roles. For companies, it’s onboarding season. For attackers, it’s something else entirely.
According to Keepnet Labs’ research on phishing susceptibility among new hires, CEO impersonation emails are 45% more likely to succeed with new hires than with experienced employees.

Attackers don’t go after your most seasoned people. They go after the ones who are still learning the ropes because there’s a window at the beginning where everything is unfamiliar and nothing feels certain.
A new employee doesn’t know what a typical request looks like. They don’t know how the CEO usually communicates. They haven’t had time to build instincts or confidence, and cybercriminals take advantage of that uncertainty.
But here’s the thing: The new employee isn’t the problem. The most dangerous employee isn’t careless. It’s the one trying to be helpful.
If you run a business, you probably already know exactly who on your team would respond first.
The real gap isn’t training. It’s the system.
Now think back to that employee’s first day.
Their laptop wasn’t ready. Access hadn’t been fully set up. Their email account was still being created. They borrowed someone else’s login to check something quickly. They saved a file locally because they couldn’t access the shared drive. They used their personal phone to look up a client number because it was faster.
None of that felt risky. It felt like being resourceful. Like doing what needed to get done on a hectic first day.
But in that first week, before everything is fully in place, a few important things happen quietly. Shared credentials create accounts nobody tracks, files end up outside of your backup systems, a personal device touches your business data, and no one explains what to do if something feels off.
The same Keepnet report found that new employees are 44% more susceptible to phishing than tenured staff. That gap doesn’t come from carelessness. It comes from chaos. When onboarding is chaotic, security becomes optional. That’s the environment the phishing email walks into.
The attack didn’t create the vulnerability. The first day did.
In financial institutions, that vulnerability can extend beyond internal systems, it can impact member trust and the advisory role those organizations play. In healthcare, it can expose protected patient data. In professional services, it can compromise client confidentiality.
What a prepared first day looks like
Fixing this doesn’t require a long security presentation on day one. It requires three things to be ready before the person walks in the door.
- Their access is configured, not improvised.
That means the laptop is ready, credentials are created and permissions are clearly defined. No borrowing logins, no temporary workarounds and no “we’ll sort that out later this week.” - They know what a normal request looks like in your business.
This can be a quick, 10-minute conversation. Does the CEO ever email about payments? Does anyone? What should they do if something feels off? This isn’t formal training; it’s basic orientation. - They have somewhere to ask questions without feeling foolish.
The employee who hesitated before clicking that email probably would have asked someone if they’d known who to ask. Most first-week mistakes happen quietly because new hires don’t want to look inexperienced.
Give them a person. Give them a process.
Why this keeps happening (and why it shouldn’t)
Most onboarding issues aren’t one-time mistakes. They’re patterns.
Access gets delayed. Workarounds get normalized. Security steps get skipped “just for now.” And over time, those small gaps become repeatable risks.
Across growing organizations in places like Portland, Eugene, and throughout Oregon, this is becoming more common as teams scale quickly without structured onboarding processes.
Well-run environments don’t just get people up and running; they make sure the same risks don’t show up with every new hire.
This is where a structured approach like the 10D Tech IT Services and Cybersecurity Solutions model changes the equation. Instead of solving onboarding issues every time someone joins, you build a system that prevents those issues from happening in the first place.
Closing
Most security mistakes don’t happen when someone ignores the rules. They happen when someone doesn’t know the rules yet.
Maybe your onboarding is already solid. Maybe your team is small enough that first days feel more personal rather than procedural.
But if you’ve ever had a new hire improvise their way through week one, or if you’re planning to bring someone on soon, it’s worth addressing before that Tuesday email arrives.
If you’re evaluating whether your onboarding process is structured for long-term consistency, not just quick fixes, that’s where a second opinion can be valuable.

And if you know another business owner who’s about to hire, send this their way. The best time to close that door is before anyone walks through it.
Frequently Asked Questions
- Why are new employees more vulnerable to phishing attacks?
Because everything is unfamiliar. They don’t yet know what normal communication looks like, and they’re more likely to act quickly to be helpful. - Is security awareness training enough to prevent this?
Not by itself. Training helps, but most first-week risks come from incomplete system-missing access controls, unclear processes, and a lack of guidance. - How does this impact regulated industries like financial institutions or healthcare?
In financial institutions, these gaps can affect member trust and advisory responsibilities. In healthcare, they can expose sensitive patient data. Regulators expect consistent processes, not improvised ones. - What should onboarding include from a security perspective?
At a minimum: pre-configured access, clear expectations for communication, and a defined process for asking questions or reporting concerns. - What does “fixing onboarding once” actually mean?
It means building a repeatable, structured onboarding process that eliminates guesswork, so every new hire enters a secure, consistent environment instead of recreating risk from scratch.
