An email lands on a Tuesday morning.
It appears to come from the CEO. The sender name checks out. The wording feels believable. Even the signature looks right.
"Hey — can you help me with something quickly? I'm stuck in meetings all day. I need you to take care of a vendor payment. I'll fill you in later."
The new hire hesitates.
They've only been here four days. Everything is still new. They don't yet know what's typical, and they definitely don't want to be the person who questions the CEO during their first week.
So they do what seems helpful.
And just like that, the breach begins.
Why the first week carries the most risk
Each spring, companies welcome a fresh group of employees, including recent graduates and summer interns beginning their first 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 don't usually target your most seasoned people. They focus on employees who are still learning the culture, the tools, and the unwritten rules because the opening stretch is full of uncertainty.
A new employee doesn't yet know what a legitimate request looks like. They don't understand how the CEO normally communicates. They haven't built the instincts or confidence to slow down and question something unusual, and criminals exploit that gap.
But here's the real issue: The new employee isn't the weak link. The biggest risk is often the person who is trying hardest to be useful.
If you lead a team, you probably already know exactly who would jump in first.
The problem isn't only training. It's the process.
Think about that person's first day.
The laptop wasn't ready. Access wasn't fully provisioned. The email account hadn't finished setting up. They borrowed a coworker's login to check one thing quickly. They saved a document locally because the shared drive wasn't available. They used a 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 any way possible.
But during that first week, while systems are still coming together, a few hidden risks start to build. Shared credentials create accounts no one monitors, files drift outside backup coverage, personal devices touch business data, and nobody explains what to do when something looks suspicious.
According to the same Keepnet report, new employees are 44% more likely to fall for phishing than longer-tenured staff. That difference isn't about recklessness. It's about disorder. When onboarding is messy, security becomes an afterthought. That's exactly the kind of environment a phishing email is designed to exploit.
The attacker 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 employee arrives.
1. Their access is set up before they arrive.
That means the laptop is ready, credentials are created, and permissions are clearly defined. No borrowed logins, no temporary fixes, and no "we'll handle it later this week."
2. They understand what normal looks like in your organization.
This can be a short, 10-minute conversation. Does the CEO ever email about payments? Does anyone? What should they do if something feels suspicious? This isn't a formal course; it's practical orientation.
3. They have a safe place to ask questions.
The employee who paused before clicking that email likely would have asked someone if they knew who to ask. Most first-week mistakes stay hidden because new hires don't want to seem unsure.
Give them a person. Give them a process.
Most security failures don't happen because someone intentionally breaks the rules. They happen because no one 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 you've ever seen a new hire improvise their way through week one — or if you're bringing someone on this spring — it's worth having the conversation before that Tuesday email shows up.
