It lands in the inbox on a Tuesday morning.
At first glance, it appears to come from the CEO. The sender name checks out. The wording feels convincing. Even the signature looks authentic.
"Hey — can you jump on something for me quickly? I'm tied up in back-to-back meetings. I need you to process a vendor payment. I'll fill you in later."
The new hire hesitates.
They've only been with the company for four days. Everything is still unfamiliar. They don't yet know what a normal request sounds like, and they definitely don't want to be the person who challenges the CEO in week one.
So they do what feels helpful and move it forward.
And in that moment, the breach begins.
Why week one is the easiest target
Each spring, businesses welcome a fresh group of employees, often recent graduates and summer interns entering their first professional roles. For your team, it's onboarding season. For cybercriminals, it's prime hunting season.
Keepnet Lab's 2025 New Hires Phishing Susceptibility Report shows that CEO impersonation emails are 45% more likely to work on new hires than on experienced staff.
Hackers don't usually chase the people with the most tenure. They target the ones still learning the culture, the systems, and the unspoken rules because the start of employment is when uncertainty is highest.
A new employee doesn't yet know what a routine request looks like. They don't know how leadership normally communicates. They haven't built the confidence or instincts that come with time, and attackers know how to exploit that gap.
But the real issue isn't the new hire. The most vulnerable employee isn't the careless one. It's the one who wants to be helpful.
If you lead a business, you already know which team member would respond before thinking twice.
The problem isn't just training. It's the setup.
Picture that employee's first day.
Their laptop wasn't ready. Access wasn't complete. Their email account was still being provisioned. They used someone else's login to check one thing quickly. They stored a file on the local drive because the shared folder wasn't available yet. They pulled up a client number on their personal phone because it was faster.
None of it felt unsafe. It felt practical. Efficient. Like normal first-day problem solving.
But during that first week, before everything is fully in place, several risks quietly stack up. Shared credentials create untracked access, files fall outside backup coverage, personal devices touch company data, and nobody explains what to do when something feels suspicious.
The same Keepnet report found that new employees are 44% more likely to fall for phishing than seasoned staff. That gap isn't about carelessness. It's about disorder. When onboarding is messy, security becomes an afterthought. That's exactly where the phishing email succeeds.
The attack didn't introduce the weakness. The first day did.
What a secure first day should include
Solving this does not require a long security lecture on day one. It requires three essentials to be ready before the employee arrives.
1. Access is prepared, not patched together.
That means the laptop is configured, credentials are created, 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 company.
This can be a fast, 10-minute conversation. Does the CEO ever ask for payment help by email? Does anyone? What should they do if something seems suspicious? This isn't formal training; it's basic onboarding.
3. They know exactly where to ask questions.
The employee who paused before clicking that email probably would have asked someone if they had a safe, obvious place to go. Most first-week mistakes happen quietly because new hires don't want to seem inexperienced.
Give them a contact. Give them a process.
Most security failures don't happen because someone intentionally breaks the rules. They happen because the rules haven't been made clear yet.
Maybe your onboarding process is already strong. Maybe your team is small enough that the first week feels hands-on instead of formal. Still, if a new hire has ever had to figure things out on the fly — or if you're planning to hire this spring — it's worth tightening the process before that Tuesday email lands.
