Phishing: What Every Employee Needs to Recognize
Phishing remains the most common way attackers get in — not because the emails are technically sophisticated, but because they are built to exploit normal human reactions to urgency and authority.
The business problem
Phishing is consistently the leading initial-access technique in breach reports year after year, not because defenses have failed to improve, but because the target — a person, under time pressure, trying to be helpful — does not change. A single successful phishing email can hand over credentials, install malware, or authorize a fraudulent wire transfer, and it takes only one click out of thousands of employees.
What modern phishing looks like
Phishing has moved well past the obviously-fake "Nigerian prince" email. Current campaigns are researched, targeted, and often arrive through channels people trust by default:
- Business email compromise — a message that appears to come from an executive or vendor, timed to a real event (an invoice due, a deal closing)
- Spear phishing — personalized using information pulled from LinkedIn, a company website, or a prior breach
- SMS and voice phishing (smishing/vishing) — the same tactics moved to text messages and phone calls, which people trust more than email by default
- QR code phishing — a malicious link hidden behind a scanned code, bypassing email link scanners entirely
Why it matters
A phishing email that succeeds does not need to be sophisticated — it needs to be timely and plausible. The financial and operational cost of a single successful phishing incident (a fraudulent wire, a ransomware deployment, a compromised mailbox used to phish customers) routinely exceeds the cost of the entire awareness program that could have prevented it.
“The best phishing emails don’t look suspicious. They look like exactly what you were expecting that day — which is why urgency and pressure, not typos, are the real signal to watch for.”
Signs to watch for
- Urgency or pressure to act immediately, bypassing normal process ("wire this today before the bank closes")
- A request that skips a verification step that would normally apply (a password reset with no second factor, a payment change with no callback)
- A sender address that is close to, but not exactly, the expected domain
- A link or attachment that wasn’t expected, even from a known contact — their account may be compromised, not them lying
- A request for credentials, gift cards, or payment changes delivered entirely over email or text with no other channel used
Practical guidance
Teach one habit above all others: when something creates urgency and asks for money, credentials, or a process exception, verify it through a second channel before acting — a phone call to a known number, not the one in the email. Make reporting a suspicious email as easy as a single button, and treat every report as useful signal, never as a nuisance.

No. Filtering catches a large share of low-effort phishing, but targeted campaigns are specifically designed to slip past filters — the human decision at the point of the click remains the last line of defense.
Urgency paired with a request to bypass a normal process — an unscheduled wire, a rushed password reset, an out-of-cycle vendor payment change. Attackers rely on pressure to short-circuit normal verification habits.
No — punitive responses discourage self-reporting, which delays containment far more than the click itself. A fast, calm report is more valuable than a perfect record.
Business email compromise usually skips malware entirely and goes straight for a fraudulent instruction — a wire transfer, a payroll change, a gift card purchase — which is why financial controls, not just technical filters, are part of the defense.
