5 Ransomware Threats Canadians Need to Know

Ransomware attacks have become a pervasive and escalating threat to individuals, businesses, and organizations worldwide, including in Canada. Cybercriminals use ransomware to encrypt valuable data, demanding a ransom for its release. The impact of such attacks can be devastating, causing financial losses, data breaches, and disruptions. In this article, we will explore five ransomware threats that Canadians need to be aware of to protect themselves and their organizations.


  1. Ryuk Ransomware

Ryuk is one of the most notorious ransomware strains and has affected numerous Canadian organizations. It’s often deployed through phishing emails or exploiting vulnerabilities in unpatched systems. Once inside a network, Ryuk quickly spreads and encrypts files, demanding hefty ransoms for decryption keys.

Canadian healthcare institutions have been particularly targeted by Ryuk, causing disruptions in patient care and raising concerns about the security of sensitive medical data. To defend against Ryuk, organizations should prioritize regular software updates, employee cybersecurity training, and robust backup solutions.

  1. Conti Ransomware

Conti is another ransomware variant that has caused significant concern in Canada. This strain typically targets critical infrastructure sectors, including healthcare, energy, and transportation. The Conti gang often threatens to release stolen data if the ransom is not paid, increasing the pressure on victims.

In response to Conti and similar threats, Canadian organizations should focus on enhancing their cybersecurity posture, including segmenting networks, implementing multi-factor authentication, and regularly testing incident response plans.

  1. Maze Ransomware

Maze ransomware gained notoriety for its unique approach of not only encrypting victims’ data but also stealing it. If victims refuse to pay the ransom, Maze operators threaten to publish the stolen information on the dark web. This dual-threat approach has targeted Canadian businesses, making data breaches a primary concern.

To protect against Maze and similar ransomware, Canadians should implement data loss prevention measures, strengthen access controls, and prioritize security awareness training for employees to mitigate the risk of successful phishing attacks.

  1. NetWalker Ransomware

NetWalker ransomware, also known as Mailto, is a strain that has targeted Canadian universities and academic institutions. Cybercriminals have exploited the shift to online learning during the COVID-19 pandemic, capitalizing on vulnerabilities in remote education systems.

Canadian educational institutions should invest in robust cybersecurity solutions, conduct regular security audits, and educate students and staff about the risks of phishing emails and malicious downloads to combat the threat of NetWalker.

  1. DoppelPaymer Ransomware

DoppelPaymer ransomware is known for its highly customized and targeted attacks on Canadian businesses. Cybercriminals behind this ransomware often exfiltrate sensitive data before encrypting files, adding another layer of concern for victims.

Canadian organizations should focus on improving their overall cybersecurity posture, including implementing intrusion detection systems, maintaining robust backups, and performing vulnerability assessments to identify and address weaknesses that could be exploited by DoppelPaymer and similar ransomware strains.

Preventing Ransomware Attacks in Canada

While these ransomware threats pose a significant risk, there are steps that Canadians can take to protect themselves and their organizations:

  1. Regular Backups: Ensure that you have reliable backup systems in place for all critical data. Regularly back up your files to offline or cloud storage, and test the backups to ensure they can be restored if needed.

  2. Patch and Update: Keep all software, including operating systems and security software, up to date. Cybercriminals often exploit known vulnerabilities, so timely updates are crucial.

  3. Employee Training: Educate employees about the dangers of phishing emails and the importance of safe online behavior. Regular training and awareness programs can help reduce the risk of successful attacks.

  4. Multi-Factor Authentication (MFA): Enable MFA wherever possible to add an extra layer of security to your online accounts.

  5. Incident Response Plan: Develop and regularly test an incident response plan that outlines the steps to take in the event of a ransomware attack. Knowing how to respond can minimize the impact of an attack.

  6. Network Segmentation: Segment your network to limit the spread of ransomware in the event of a breach. Isolate critical systems and data from less sensitive areas.

  7. Security Software: Invest in reputable antivirus and anti-malware software to detect and remove threats before they can cause damage.


Ransomware threats in Canada are a growing concern, with cybercriminals continuously evolving their tactics and targeting a range of organizations. Being aware of these threats and implementing robust cybersecurity measures is essential for individuals and businesses alike. By staying informed, regularly updating software, educating employees, and following best practices, Canadians can significantly reduce their vulnerability to ransomware attacks and safeguard their data and systems. Remember, prevention is key in the battle against ransomware.
