An email lands on a Tuesday morning.
It appears to come from the CEO. The sender name is right. The wording sounds believable. Even the signature feels authentic.
"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 hire hesitates.
They've only been with the company for four days. They're still learning the workflow, still figuring out what normal looks like, and they don't want to be the person who doubts the CEO in week one.
So they help.
And that one moment is enough to cause real harm.
Why the first week is the riskiest week
Each spring, companies welcome a fresh group of employees, many of them recent graduates and summer interns stepping into their first professional roles. For leadership, it's onboarding season. For attackers, it's opportunity season.
According to Keepnet Lab's 2025 New Hires Phishing Susceptibility Report, CEO impersonation emails are 45% more likely to succeed with new hires than with experienced employees.
Cybercriminals don't usually target your most experienced staff first. They focus on the people still learning the basics, because the early days are full of uncertainty and unfamiliar routines.
A new employee may not recognize what a legitimate request looks like. They may not know how the CEO normally communicates. They haven't built the instincts or confidence that come with time, and attackers count on that gap.
But the real issue isn't the new hire. The biggest risk isn't a careless employee; it's a well-meaning one trying to do the right thing.
If you lead a business, you probably already know who on your team would answer fast.
The problem isn't just training. It's the process.
Think about that employee's first day.
The laptop wasn't fully ready. Access wasn't complete. Their email account was still being built. They borrowed a coworker's login to check something quickly. They saved a document on their device because the shared drive wasn't available. They used a personal phone to look up a client number because it was faster.
Nothing about that seemed dangerous. It felt practical. Efficient. Like the only way to keep moving on a busy first day.
But during that first week, before everything is in place, several security gaps appear quietly. Shared credentials create untracked access. Files drift outside your backup systems. Personal devices touch business data. No one has explained what to do when something doesn't feel right.
The same Keepnet report found that new employees are 44% more susceptible to phishing than tenured staff. That difference isn't caused by negligence. It's caused by disorder. When onboarding is messy, security becomes an afterthought. That's exactly the environment a phishing email is looking for.
The attack didn't create the weakness. The first day did.
What a secure first day should include
Solving this doesn't require a long lecture on security policy. It requires three essentials to be ready before the employee arrives.
1. Their access is set up properly, not patched together.
That means the laptop is ready, credentials are issued, and permissions are clearly assigned. No borrowed logins, no temporary fixes, and no "we'll handle it later this week."
2. They understand 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 when something feels suspicious? This isn't a formal course; it's basic orientation.
3. They know exactly where to ask questions without feeling embarrassed.
The person who paused before clicking that email probably would have asked for help if they knew who to ask. Many first-week mistakes happen quietly because new hires don't want to appear inexperienced.
Give them a person. Give them a path.
Most security failures don't happen because someone ignores the rules. They happen because no one has explained the rules yet.
Maybe your onboarding is already strong. Maybe your team is small enough that the first few days feel more personal than procedural. But if you've ever watched a new hire improvise through week one — or if you're planning to hire this spring — it's worth fixing the process before that Tuesday email shows up.
