In an October report on the top cybersecurity threats in 2025, BDO Canada said businesses must identify and address threats coming from nation-state actors, cybercriminal groups, and individual hackers. 

BDO Canada is a network of public accounting, tax, consulting, and business advisory firms. Its report highlights that nation-state actors are among the most “organized and capable groups in the cyber threat landscape,” investing heavily in what they do to gain geo-political advantages.

Cybercriminal groups are more focused on financial gain. These groups range from sophisticated outfits that can operate with a degree of state backing, to less organized but highly skilled teams. Their tools can sometimes end up in the hands of criminals.

As for the last group, BDO Canada individual hackers and small groups (hacker enthusiasts) have varying motives (from activism to financial gain or notoriety) and present different organizational challenges. “Technologies that enable hacking are becoming more accessible through platforms that ‘hack-as-a-service,’ allowing even less experienced individuals to pose a significant risk.”

So what should businesses keep an eye out for? According to the BDO Canada update, they should be aware of cyber espionage: business email attacks, stolen usernames and passwords, insider threats (individuals with authorized access exploit their position), and supply chain attacks (seeking to compromise third-party vendors or suppliers).

They should also watch out for cyber sabotage through things like ransomware, Denial of service (DoS) attacks (by disrupting the availability of online services or websites), and process sabotage (attacking data-dependent processes essential for smooth operations).

Cyber fraud (such as credential exposure, account takeovers, and payment fraud) and misinformation (brand abuse and election fraud) are also important to be aware of.
