It lands in the inbox on a Tuesday morning.
The message appears to be from the CEO. The name checks out. The tone sounds authentic. Even the signature feels convincing.
"Hey — can you help me with something quickly? I'm tied up in meetings. I need you to take care of a vendor payment. I'll fill you in later."
The new hire stops and reads it again.
They've only been there four days. They're still learning the company, still unsure what normal looks like, and definitely not eager to challenge a request from the CEO in their first week.
So they step in and help.
And in that moment, the damage is already underway.
Why the first week creates the biggest risk
Every spring, businesses welcome a fresh group of employees, including recent graduates and summer interns starting their first professional roles. For your company, it's onboarding season. For attackers, it's prime opportunity.
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.
Cybercriminals don't start with your most seasoned team members. They target the people who are still learning because the early days are full of uncertainty, and uncertainty is easy to exploit.
A new employee doesn't yet know what a legitimate request looks like. They don't know how the CEO normally communicates. They haven't had time to build instinct or confidence, and attackers use that gap to their advantage.
But the issue isn't the new hire. The most vulnerable employee isn't the careless one — it's the one trying hardest to be helpful.
If you manage a business, you probably already know exactly who on your team would reply first.
The real weakness isn't training. It's the setup.
Think back to that person's first day.
The laptop wasn't ready. Access wasn't fully provisioned. The email account was still being built. They borrowed a coworker's login to check one thing quickly. They saved a file on their desktop because the shared drive wasn't available. They used a personal phone to look up a client number because it was faster.
None of it felt dangerous. It felt practical. It felt like finding a way to keep moving on a hectic first day.
But during that first week, before everything is properly in place, a few critical problems start to form quietly. Shared credentials create untracked access, files sit outside your backups, personal devices touch company data, and nobody has explained what to do when something seems suspicious.
The same Keepnet report showed that new employees are 44% more likely to fall for phishing than tenured staff. That difference isn't about laziness. It's about disorder. When onboarding is messy, security becomes optional. 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 look like
Solving this doesn't call for a long security lecture on day one. It calls for three essentials being ready before the new hire arrives.
1. Their access is set up, not improvised.
That means the laptop is ready, credentials already exist, and permissions are clearly defined. No shared 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 quick 10-minute conversation. Does the CEO ever email about payments? Does anyone? What should they do if something feels wrong? This isn't a formal training session; it's a simple orientation that prevents confusion.
3. They have a safe place to ask questions.
The employee who paused before opening that email likely would have checked with someone if they'd known who to ask. Most first-week errors happen quietly because new hires don't want to look inexperienced.
Give them a contact. Give them a process.
Most security mistakes don't happen because someone ignores 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 first days feel more personal than procedural. But if you've ever seen a new hire improvise their way through week one — or if you're planning to bring someone on this spring — it's worth addressing before that Tuesday email ever arrives.
