Top Cybersecurity Threats Facing Montreal Businesses in 2026
Top Cybersecurity Threats Facing Montreal Businesses in 2026
1. Ransomware Attacks
Ransomware remains a major cybersecurity threat in Canada. Attackers can encrypt business data, disrupt operations, and threaten to release stolen information.
The Canadian Centre for Cyber Security assesses ransomware as the top cybercrime threat facing Canada's critical infrastructure and expects ransomware actors to continue evolving their extortion techniques.
Businesses should:
- Maintain secure and tested backups.
- Use MFA on important accounts.
- Keep software updated.
- Limit administrator privileges.
- Monitor for suspicious activity.
- Maintain an incident response plan.
2. Phishing and Business Email Compromise
Phishing attacks attempt to trick employees into clicking malicious links, revealing credentials, or transferring information. Business email compromise can also involve impersonating executives, suppliers, or customers.
The Cyber Centre reports that phishing is one of the most commonly reported forms of fraud in Canada and that AI tools are making phishing messages easier to personalize and produce at scale.
Businesses should provide regular employee security awareness training and use email security controls, MFA, and verification procedures for sensitive requests.
3. AI-Powered Cyberattacks
Artificial intelligence is becoming a tool for both legitimate businesses and cybercriminals. Attackers can use AI to create more convincing phishing messages, automate content generation, analyze information, and support social engineering.
The Cyber Centre assesses that AI is lowering barriers to malicious activity and improving the quality, scale, and precision of some cyber threats.
Businesses should establish clear policies for using AI tools and avoid entering confidential customer, financial, or business information into AI services without appropriate approval and safeguards.
4. Stolen Passwords and Account Takeovers
Compromised passwords can give attackers access to email, cloud applications, financial systems, and other business resources.
To reduce this risk:
- Enable MFA.
- Use strong, unique passwords.
- Use a business password manager.
- Remove inactive accounts.
- Review administrator privileges.
- Monitor unusual login activity.
Microsoft 365 administrators should receive particular attention because compromised administrative accounts can provide extensive access to business resources.
5. Vulnerable and Outdated Software
Attackers frequently look for weaknesses in outdated operating systems, applications, plugins, network equipment, and internet-facing services.
Create a patch management process that identifies vulnerable systems, prioritizes important updates, and replaces software that is no longer supported.
Regular vulnerability assessments can also help identify weaknesses before attackers discover them.
6. Third-Party and Supply-Chain Attacks
A business can be affected by a cybersecurity incident involving one of its technology providers. Cloud platforms, software vendors, IT providers, website providers, and other suppliers may have access to business systems or information.
The Cyber Centre identifies increasing vendor concentration and supply-chain attacks as important trends in Canada's cyber threat environment.
Businesses should review important vendors and understand what information and systems each provider can access.
7. Data Theft and Privacy Incidents
Cyberattacks do not always involve destroying systems. Attackers may attempt to steal customer information, employee information, financial records, intellectual property, or other sensitive data.
Quebec organizations should understand their responsibilities for protecting personal information and responding to confidentiality incidents. The Commission d'accès à l'information du Québec provides guidance for organizations handling personal information.
Businesses should identify sensitive information, restrict access, use appropriate security controls, and establish procedures for responding to potential privacy incidents.
8. Attacks on Websites and Online Services
Websites and online applications can become entry points for attackers when software, plugins, credentials, or configurations are not properly maintained.
Businesses should:
- Keep website software updated.
- Protect administrator accounts with MFA.
- Use HTTPS.
- Remove unused plugins and accounts.
- Monitor for suspicious activity.
- Maintain reliable website backups.
- Conduct security assessments when appropriate.
9. Insider Threats and Excessive Access
Security risks can also originate inside an organization. An employee, contractor, or compromised account may have access to information that is not necessary for their role.
Apply the principle of least privilege and regularly review permissions. When employees leave the company, promptly disable their accounts and recover company devices and access credentials.
10. Lack of Cybersecurity Preparedness
One of the biggest challenges for a business is not knowing what to do when an incident occurs.
A cybersecurity incident response plan should define:
- Who is responsible for managing the incident.
- How suspicious activity should be reported.
- How affected systems will be isolated.
- Who communicates with management.
- How evidence will be preserved.
- How backups and recovery procedures will be used.
- When external specialists or authorities should be contacted.
