A clear, no-hype guide to what is changing, how to reduce risk, and what to do in the first hour of an incident.
The risk is local. The attackers are not.
Your business answers to Canadian laws, contracts, and customer expectations, while criminal tools, infrastructure, and markets operate globally. Canada’s Cyber Centre describes a resilient global cybercrime ecosystem powered by ready-to-use services.
In 2023, about one in six businesses with 10 or more employees reported an incident they considered impactful.
Canadian recovery spending doubled from 2021; small and medium businesses each accounted for about $300 million.
Only just over one quarter of businesses in the survey had written cybersecurity policies in 2023.
The five threats
Polished messages imitate leaders, suppliers, and customers. The goal is to steal a login, redirect payroll, or get a payment approved.
Priority: Verify financial changes through a known second channel; use phishing-resistant MFA and separate administrator accounts.Encryption is no longer the only lever: criminals often steal data first and threaten to publish it.
Priority: Keep isolated, tested backups; protect administration tools; rehearse a plan that names who decides, who calls, and what gets disconnected.A forgotten device, weak remote access, or end-of-life application can become the easiest way in.
Priority: Maintain an inventory, automate patching, retire unsupported systems, and minimize anything directly exposed to the internet.A compromised IT, software, or cloud provider can create a path into many customers at once.
Priority: Require MFA, logs, incident notice, access limits, and recovery evidence; review integrations and service accounts.A bad sharing link, lost device, or sensitive data pasted into an unapproved tool can create a breach without malware.
Priority: Classify data, enforce least privilege, govern external sharing, and publish a simple approved-AI policy.The 80/20 plan
These follow the spirit of the Cyber Centre’s baseline controls for small and medium organizations: focus effort on a small number of high-impact safeguards.
Phishing-resistant MFA, separate admin accounts, least privilege, and immediate offboarding.
A living inventory, automated updates, failure follow-up, and a replacement schedule.
Endpoint and email protection, monitoring, short training, and out-of-email payment verification.
Encrypted, isolated, offsite backups; restore tests; and agreed recovery objectives.
Named roles, printed contacts, escalation rules, insurer, legal counsel, communications, and an annual exercise.
The first hour
Do not reset everything or delete evidence at random. A disciplined response helps contain the incident, preserve facts, communicate correctly, and restore in the right order.
