It lands in the inbox on a Tuesday morning.
The sender appears to be the CEO. The name checks out. The wording feels legitimate. Even the signature seems right.
"Hey — can you help me with something quickly? I'm stuck in back-to-back meetings. I need you to handle a vendor payment. I'll explain later."
The new hire hesitates.
They've only been at the company for four days. They're still learning the workflow, still figuring out what normal looks like, and they certainly don't want to be the person who questions the CEO during their first week.
So they step in and do it.
And with that single decision, the breach begins.
Why week one is the highest-risk period
Every spring, companies welcome a fresh group of employees, including recent graduates and summer interns entering their first professional roles. For business leaders, it's onboarding season. For cybercriminals, it's prime hunting season.
Keepnet Lab's 2025 New Hires Phishing Susceptibility Report found that CEO impersonation emails are 45% more likely to work on new hires than on experienced staff.
Attackers aren't chasing your most seasoned team members. They're targeting the people still getting oriented, because the early days are filled with uncertainty and unfamiliar routines.
A new employee doesn't know what a legitimate request usually sounds like. They don't understand how the CEO typically communicates. They haven't yet developed the instincts or confidence that help them spot fraud, and criminals use that gap to their advantage.
But the issue isn't the new hire. The biggest risk isn't the person who makes mistakes. It's the person who is trying hard to be helpful.
If you lead a team, you probably already know exactly who would respond first.
The problem isn't just training. It's the setup.
Now picture that employee's first day.
The laptop wasn't ready. Access was incomplete. The email account wasn't fully active yet. They used someone else's login to check one quick thing. They saved a document locally because the shared drive wasn't available. They reached for their personal phone to find a client number because it was faster.
None of that felt dangerous. It felt practical. It felt like getting through a hectic first day the best way they could.
But during that first week, while systems are still coming together, several risks quietly appear. Shared credentials create untracked accounts, files slip outside backup coverage, personal devices touch company data, and no one has explained what to do when something seems suspicious.
The same Keepnet report found that new employees are 44% more likely to fall for phishing than tenured staff. That gap isn't about negligence. It's about disorder. When onboarding is messy, security becomes an afterthought. That's the environment the phishing email is counting on.
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 requires three essentials to be in place before the new employee arrives.
1. Access is set up in advance, not patched together.
The laptop is ready, credentials are created, and permissions are clearly mapped out. No borrowed logins, no stopgap fixes, and no "we'll handle it later this week."
2. They understand what a normal request looks like for your company.
This can be a quick 10-minute conversation. Does the CEO ever send payment requests? Does anyone? What should the employee do if a message feels questionable? This isn't formal training; it's practical orientation.
3. They know exactly where to go with questions.
The employee who paused before opening that email probably would have asked for help if they knew who to contact. Most first-week mistakes stay hidden because new hires don't want to look unprepared.
Give them a person. Give them a process.
Most security failures don't happen because someone ignores the rules. They happen because no one has explained the rules yet.
Maybe your onboarding process is already strong. Maybe your team is small enough that the first few days feel more personal than formal. But if a new hire has ever had to improvise through week one — or if you're bringing someone on board this spring — it's worth fixing the gaps before that Tuesday morning email shows up.
