The email lands on a Tuesday morning.
It appears to come from the CEO. The name is right. The wording sounds right. Even the signature looks convincing.
"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. Everything is still new. They haven't learned what normal looks like yet, and they certainly don't want to be the person who questions the CEO during their first week.
So they do what seems helpful and move it forward.
And in that moment, the breach is already in motion.
Why week one is the riskiest week
Every spring, companies welcome a fresh group of employees, many of them recent graduates and summer interns stepping into their first professional roles. For your business, it's onboarding season. For attackers, it's prime opportunity.
According to Keepnet Lab's 2025 New Hires Phishing Susceptibility Report, CEO impersonation emails are 45% more likely to work on new hires than on experienced employees.
Cybercriminals don't usually target your most seasoned team members. They focus on the people still learning the basics, because the early days are full of uncertainty and unfamiliar processes.
A new employee doesn't yet know what an ordinary request looks like. They don't know how leadership typically communicates. They haven't had time to build confidence or instincts, and attackers use that uncertainty to their advantage.
But the issue isn't the new employee. The biggest risk isn't someone being reckless. It's someone trying to do the right thing.
If you manage a team, you probably already know exactly who would respond first.
The real problem isn't training. It's the process.
Think back to that employee's first day.
The laptop wasn't ready. Access wasn't fully set up. Their email account was still pending. They borrowed a coworker's login to get something done quickly. They saved a file locally because the shared drive wasn't available. They used a personal phone to look up a client number because it was faster.
None of that felt dangerous. It felt practical. It felt like getting through a busy first day.
But during that first week, before everything is fully in place, a few risky habits can take root quietly. Shared credentials create untracked access, files leave your backup environment, personal devices touch company data, and no one explains what to do when something feels suspicious.
The same Keepnet report found that new employees are 44% more susceptible to phishing than tenured staff. That gap isn't about negligence. It's about disorder. When onboarding is messy, security becomes an afterthought. That's exactly where the phishing email gains a foothold.
The attack didn't create the weakness. The first day did.
What a secure first day should include
Solving this doesn't require a lengthy security lecture on day one. It takes three essentials being ready before the person ever arrives.
1. Their access is fully set up, not figured out on the fly.
That means the laptop is ready, credentials are created, and permissions are clearly assigned. No borrowed logins, no temporary fixes, and no "we'll deal with that later this week."
2. 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 a request feels wrong? This isn't formal training; it's simple orientation that gives them context.
3. They have a safe place to ask questions.
The employee who paused before clicking that email might have checked with someone if they knew 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.
Most security failures don't happen because someone ignores the rules. They happen because the rules haven't been made clear yet.
Maybe your onboarding is already strong. Maybe your team is small enough that the first week feels more personal than procedural. But if you've ever watched a new hire improvise their way through week one — or if you're planning to hire this spring — it's worth having the conversation before that Tuesday email shows up.
