Many Nanaimo businesses think of phishing as suspicious emails filled with spelling mistakes or obvious red flags.
But some of the more effective attacks today are much quieter.
They happen when key people are away.
How Out-of-Office Phishing Works
The attack often begins with a simple step. An attacker sends emails to a company and receives an automatic out-of-office reply.
That reply may confirm the person is unavailable, how long they will be away, alternative emails and who else to contact.
From there, the attacker adjusts their approach.
They may impersonate the absent employee and contact a colleague, supplier, or finance team. Because the person is known to be away, there is less chance of immediate verification. Requests that might normally be double-checked are more likely to move forward.
What Gets Exploited
Out-of-office phishing does not rely on technical vulnerabilities. It relies on normal business behaviour.
For a Nanaimo business, the attack works because it takes advantage of reduced oversight, trust in familiar names, and the pressure to keep operations moving.
It is less about poorly written emails and more about using real business context to appear legitimate.
Why Out-of-Office Messages Can Create Risk
Many out-of-office replies include far more detail than necessary.
We often see messages that share personal phone numbers, travel dates or detailed absence timelines, alternate private email addresses or named internal contacts for escalation. While this is usually intended to be helpful, it can give attackers exactly the information they need.
A personal phone number creates a new channel for impersonation. Travel details confirm when someone cannot respond. Private email addresses bypass normal security controls. Naming internal contacts helps attackers redirect their efforts.
Why It Is Increasing
Phishing is becoming more targeted and better timed. Attackers no longer rely on volume alone. They look for small signals and act when verification is less likely.
Automatic replies, social media updates, and predictable business patterns all contribute to that visibility.
According to the Canadian Centre for Cyber Security, targeted phishing continues to evolve by leveraging real organizational context and timing.
How Nanaimo Businesses Can Reduce the Risk
Out-of-office phishing is largely preventable with a few practical adjustments.
-
Keep out-of-office replies simple and avoid unnecessary detail
-
Do not include personal phone numbers or alternate email addresses
-
Avoid naming specific internal contacts unless required
-
Require verification for payment or sensitive requests, especially during absences
-
Encourage staff to question requests, even if they appear internal
These small changes remove the conditions that make these attacks effective.
Staying Ahead of Timing-Based Attacks
Out-of-office phishing is not about technical failure. It is about timing and process.
Many Nanaimo businesses already have the right tools in place. The difference is how those tools are supported by awareness and clear procedures.
At NCI Technical, we help Nanaimo businesses strengthen email security, review internal workflows, and reduce the likelihood that routine communication becomes a point of risk.
