It’s a quiet Monday afternoon when your inbox pings. The email looks like it’s from Microsoft, warning that your account will be suspended in 24 hours. There’s a link to “verify your account immediately.” Your finger hovers over the link.
Stop.
Right.
There.
You might be looking at a phishing email designed to steal your credentials and compromise your entire organization. For multi-site professional services firms across Alberta, one wrong click can lead to data breaches, client information theft, and significant business disruption.
Here’s what your team needs to know.
What Phishing Is (and Why It’s So Dangerous)
Phishing emails are fake messages that trick people into giving away sensitive information or installing malware. Unlike other cyberattacks that target technical vulnerabilities, phishing attacks target human psychology.
These attacks work because they create urgency, fear, or curiosity. They often appear to come from trusted sources like banks, software companies, IT service providers, or even colleagues. The goal is always the same: get you to click a link, download an attachment, or share sensitive information.
For professional services firms managing client data across multiple locations, a single successful phishing attack can open the door to your entire business network, compromising confidential information and damaging client trust – something that’s notoriously hard to earn back.
Common Phishing Scams Targeting Professional Services
1. Account Suspension Warnings
Attackers send emails claiming your Office 365, QuickBooks, or other business software accounts will be suspended unless you verify your credentials immediately. These emails often look identical to legitimate notifications.
2. Fake Invoice Requests
You receive an email that appears to be from a vendor or client with an attached invoice. The attachment contains malware that installs when opened, giving attackers access to your network.
3. Executive Impersonation
Someone creates an email address that looks like it belongs to a senior partner or manager. They request urgent wire transfers or sensitive client information or ask you to purchase gift cards for a “client meeting.”
4. Tax Season Exploitation
During busy periods, attackers send emails about tax deadlines, CRA updates, or urgent client requests. The pressure to respond quickly makes people less likely to verify the sender’s identity.
5. Client Data Requests
Fake emails appear to come from existing clients requesting sensitive documents or account information. These attacks are particularly effective because they reference real client relationships.
How to Recognize Business Cyber Threats in Email
Sender Verification
Check the actual email address, not just the display name. Look for slight misspellings in domain names or unusual characters that might indicate spoofing.
Link Inspection
Hover over links without clicking to see the actual destination. Legitimate companies use their official domains for all communications.
Attachment Caution
Be suspicious of unexpected attachments, especially executable files or documents that ask you to enable macros. When in doubt, contact the sender through a different method to verify.
Urgency and Pressure
Legitimate business communications rarely demand immediate action without proper context. Take time to verify urgent requests through official channels.
Are Grammar and Formatting Still Good Indicators of a Phishing Email in 2025?
In days gone by, poor grammar, unusual formatting, or generic greetings often indicated phishing attempts. However, with the advent of AI, it’s easier than ever for cybercriminals to create emails that aren’t just grammatically flawless but even match the tone and quirks of the sender they’re impersonating.
So while you can keep an eye on spelling mistakes you know are unlike the sender, don’t put too much stock in spotting scam phishing attempts this way.
How to Build Cybersecurity Awareness in Your Business
Regular Training Sessions
Schedule regular training sessions across all locations. Make training interactive by having employees identify suspicious emails together and use real examples of phishing attempts your industry faces.
An IT and cybersecurity service provider like us can help you secure suitable awareness training for your business.
Simulated Phishing Tests
Send fake phishing emails to your team to test their awareness. When someone clicks, provide immediate education rather than punishment. Track improvement over time and celebrate success stories.
Clear Reporting Procedures
Create simple ways for employees to report suspicious emails. Use a dedicated email address or IT ticket system. Respond quickly to reports and share lessons learned with the entire team.
Role-Based Training
Customize training based on job functions to improve relevance and retention. Accounting staff need different awareness than client-facing teams. Senior partners require training on executive-targeted attacks.
Protecting Multi-Site Operations
Consistent Policies
Ensure all locations follow the same security procedures. Different offices shouldn’t have different standards for handling suspicious emails.
Centralized Monitoring
Use security tools that provide visibility across all locations. This helps identify patterns and respond quickly to threats affecting multiple sites.
Regular Communication
Share threat intelligence between locations. A phishing campaign targeting your Calgary office might also target Edmonton, so make use of advance warnings.
Beyond this, you can create a stronger culture of cybersecurity in your business by:
- Having senior partners participate in training and openly discuss security challenges
- Sharing security updates and success stories through newsletters or team meetings
- Rewarding employees who report suspicious emails or follow procedures correctly
- Turning phishing incidents into learning opportunities for the entire team (instead of approaching them with blame)
Top Technical Prevention Measures
Email Security Filters
Deploy advanced email filtering that goes beyond basic spam detection. An experienced cybersecurity team can help you look for solutions that analyze sender reputation, content patterns, and link destinations before emails reach inboxes.
Multi-Factor Authentication
Require additional verification steps for all business applications. Even if someone steals a password through phishing, they still can’t access accounts without the second factor.
Endpoint Detection and Response (EDR)
Implement EDR solutions that monitor workstations for suspicious activity. These systems can detect and stop malware that gets through email filters, providing a crucial backup layer of protection.
Regular Software Updates
Keep all systems updated with the latest security patches. Many phishing attacks succeed because they exploit known vulnerabilities in outdated software.
Network Segmentation
Separate critical systems from general network access. If one workstation gets compromised through phishing, segmentation limits how far attackers can spread through your network.
What to Do When Phishing Does Strike
1. Don’t Click Anything
If you suspect an email is phishing, don’t click links, download attachments, or reply to the message. This prevents potential compromise.
2. Report Immediately
Forward suspicious emails to your IT team or security contact. Include the full email headers if possible – this helps with analysis.
3. Verify Independently
If the email claims to be from a client or vendor, contact them directly using known phone numbers or email addresses to confirm the request.
4. Change Passwords
If you accidentally provided credentials to a phishing site, change those passwords immediately. Also change passwords for any accounts that use the same credentials.
5. Monitor Accounts
Watch for unusual activity in your email, bank accounts, and business systems. Report any suspicious activity to your IT team right away.
Final Thoughts
Phishing remains one of the most effective ways criminals target professional services firms. These attacks succeed because they exploit human nature rather than technical weaknesses.
Your best defence combines employee training, technical safeguards, and clear procedures for handling suspicious emails. Regular training helps your team recognize phishing scams targeting professional services, while technical measures like EDR provide backup protection when human defences fail.
Remember that cybersecurity awareness for businesses never boils down to a one-time training session. It requires ongoing education, regular testing, and continuous improvement as business cyber threats evolve – but the time invested in training and prevention always costs less than recovering from a successful attack.
