Small law firms in Alberta face five cybersecurity risks that deserve particular attention: phishing and account compromise, exposure of confidential client information, weak Microsoft 365 security, ransomware and compromised devices, and financial or trust-account fraud.
These aren’t hypothetical concerns. In February 2026, the Law Society of Alberta reported receiving reports of Alberta law firms being hacked and cybercriminals gaining access to client files.
For a law firm with 10–50 employees, cybersecurity doesn’t need to become overwhelmingly complicated. A good starting point is understanding where the greatest risks are and putting practical safeguards around them.
1. Phishing and Account Compromise
Phishing remains dangerous because attackers don’t necessarily need to defeat your technology. Sometimes they just need to convince one person to give them a password.
A phishing email may imitate Microsoft, a client, colleague, bank, vendor, or other trusted organization. Once credentials are stolen, an attacker may attempt to access email and other systems.
Multi-factor authentication (MFA), advanced email filtering, employee awareness, and security monitoring can work together to reduce this risk.
2. Exposure of Confidential Client Information
Cybersecurity has an additional dimension for lawyers because protecting client confidentiality is a professional obligation.
The Law Society of Alberta’s Code of Conduct requires lawyers to maintain competence. The commentary to Rule 3.1-2 specifically addresses technological competence, stating that lawyers should understand the benefits and risks associated with relevant technology while recognizing their duty to protect confidential information under Rule 3.3.
The Law Society also makes clear that technological competence isn’t one-size-fits-all. The appropriate level depends on factors such as the lawyer’s practice area, location, responsibilities, and client requirements.
For law firms, a practical framework is:
Know → Protect → Monitor → Respond
Know where confidential information is stored. Protect access to it. Monitor for suspicious activity. Have a plan for responding when something goes wrong.
3. Weak Microsoft 365 Security
Microsoft 365 may contain some of a firm’s most important business information, particularly email and documents.
Simply having Microsoft 365, however, doesn’t mean every appropriate security measure has been configured.
Law firms should consider five areas:
- MFA configuration
- Adequate and timely user onboarding and offboarding
- Advanced email security and phishing filtering
- Microsoft 365 data backups
- Security monitoring and alerts
These controls address different parts of the problem. MFA can make stolen passwords harder to exploit, while monitoring helps identify suspicious activity. Backups address recovery if important information is lost or compromised.
4. Ransomware and Compromised Devices
Every computer accessing firm information creates another potential point of entry.
An unpatched computer, compromised laptop, malicious attachment, or poorly protected remote device can expose the firm to unnecessary risk.
Law firms should consider endpoint protection, patch management, device encryption, backups, security monitoring, and appropriate controls for remote work.
The objective isn’t to eliminate every possible risk. No security program can guarantee that.
The goal is to create multiple layers so one mistake or technical failure doesn’t automatically become a major incident.
5. Financial and Trust-Account Fraud
Cybersecurity can also become a financial issue.
In March 2025, the Law Society of Alberta warned that cybercriminals had been impersonating bank security or trust-safety personnel and using social engineering to gain access to lawyers’ trust accounts.
The Law Society describes lawyers and their trust accounts as high-value targets and recommends measures including cybersecurity and social-engineering training, email authentication, MFA, and consideration of secondary authentication for withdrawals.
There are also specific reporting requirements when fraud occurs. Under Rule 119.40 of the Rules of the Law Society of Alberta, a law firm must immediately report certain fraud or theft involving money, trust accounts, general accounts, or trust property to the Law Society.
That makes protection of financial systems more than an ordinary IT consideration for firms operating trust accounts.
What Happens If an Alberta Law Firm Is Breached?
Having an incident-response plan before a breach occurs is important.
The Law Society advised Alberta lawyers in February 2026 that, depending on the circumstances, a cybersecurity breach may create reporting obligations involving the affected client, Alberta Lawyers Indemnity Association (ALIA) or another insurer, the Office of the Information and Privacy Commissioner of Alberta (OIPC), and the Law Society’s Trust Safety department.
Firms shouldn’t wait for an incident to determine who needs to be contacted.
A simple starting framework is:
Detect → Contain → Investigate → Recover → Report
The exact response will depend on the incident and the firm’s legal and professional obligations.
Start With a Five-Risk Review
An Edmonton law firm can begin by asking five questions:
- Can stolen credentials give someone access to our systems?
- How are we protecting confidential client information?
- Is our Microsoft 365 environment actively secured and monitored?
- Are our computers protected, patched, backed up, and monitored?
- Do we have safeguards around financial transactions and trust accounts?
If any answer is unclear, that’s a useful place to begin a cybersecurity review.
