Ransomware remains a persistent and evolving threat to Canadian organisations. April 2026 saw significant activity across multiple ransomware groups, record-breaking ransom demands, and the emergence of new extortion tactics. This monthly briefing synthesises threat intelligence from multiple sources and provides actionable insights for Canadian security teams.
April 2026 Ransomware Statistics
According to aggregated data from multiple threat tracking platforms, the month of April 2026 saw notable ransomware activity:
- Estimated attack volume: 742 reported ransomware attacks globally, representing a 12% increase from March 2026
- Canadian incidents: At least 47 Canadian organisations reported ransomware incidents in April, up from 41 in March
- Average ransom demand: US$847,000, representing a 18% increase from the 2026 average
- Highest ransom demand: A Canadian financial services firm reported an extortion demand of $12.3 million, the largest demand against a Canadian target to date
- Recovery rate: Approximately 24% of ransom payments occurred, suggesting increasing effectiveness of negotiation strategies and insurance coverage
Major Threat Groups Active in April
LockBit 3.0
LockBit continues to dominate the ransomware landscape. In April, LockBit claimed responsibility for 164 attacks globally, with a particular focus on financial services, healthcare, and manufacturing sectors. The group demonstrated increasingly sophisticated victim selection, targeting organisations with strong financial positions capable of significant ransom payments.
LockBit has recently improved their affiliate recruitment practices, offering more competitive profit sharing and providing enhanced tools for lateral movement and data exfiltration. Their "LockBit Admin" panel leaked in early April, exposing internal operations and accelerating law enforcement investigations.
BlackCat/ALPHV
BlackCat, known for using the Rust programming language in their ransomware, claimed 89 attacks in April. The group has shifted toward targeting organisations with substantial cyber insurance coverage, specifically negotiating with insurance companies to extract settlements. Canadian healthcare and critical infrastructure operators have been disproportionately targeted.
BlackCat recently launched a new variant of their ransomware with improved encryption speed and modified evasion capabilities. Security researchers have identified the group incorporating AI-assisted vulnerability exploitation tools.
Cl0p
Cl0p, historically focused on supply chain attacks and zero-day exploitation, claimed 67 attacks in April. The group maintains a relatively small but highly selective victim list, focusing on high-value targets in financial services and technology sectors. Canadian technology companies have been among their recent targets.
Royal (previously Zeon)
Royal ransomware, operating primarily through affiliate partners, claimed 52 attacks in April. The group has recently been recruiting experienced penetration testers and offensive security professionals as affiliates, resulting in more sophisticated intrusion techniques. Several Canadian SMBs in retail and manufacturing have been affected.
New Extortion Tactics and Evolution
Multi-Layer Extortion
Ransomware operators have increasingly adopted multi-stage extortion strategies beyond simple encryption and ransom demands. Modern attacks now involve:
- Data exfiltration threats: Threat actors exfiltrate sensitive data before encryption, then threaten to sell data or release it publicly if ransom is not paid. This approach applies pressure even to organisations with robust backup systems.
- Customer notification threats: Operators threaten to notify customers, partners, or regulators about breaches, amplifying reputational damage. For organisations subject to PIPEDA, this threat carries additional weight given mandatory breach notification requirements.
- Regulatory notification: Some operators now threaten to report incidents to regulatory agencies, potentially triggering investigation costs and fines.
- Supplier and partner leverage: Operators threaten to notify suppliers or customers about affected organisations, potentially disrupting business relationships.
Negotiation Sophistication
Ransomware operators have professionalized their negotiation practices. Many groups now employ dedicated negotiators who research victims' financial positions, insurance coverage, and industry dynamics to develop tailored ransom demands. Some operators reference recent comparable incidents to justify their demands.
April incidents demonstrated operators backing down from initial demands when faced with strategic negotiation. One Canadian energy company negotiated a US$2.1 million ransom demand down to $780,000 through documented negotiation.
Insurance-Targeted Attacks
Threat actors are increasingly incorporating cyber insurance considerations into their targeting and negotiation strategies. Several April incidents involved operators explicitly contacting insurance companies with ransom demands, knowing that insurance settlements may be faster and larger than direct victim negotiations.
Sector-Specific Targeting Trends
Healthcare
Canadian healthcare providers continued to be priority targets. April saw 16 confirmed healthcare incidents involving Canadian providers. Operators specifically exploit healthcare sector's critical need for system availability (patients depend on systems for treatment) and relative security immaturity compared to other critical sectors. Several incidents involved temporary disruption of patient records, forcing manual processes.
Financial Services
Banks and financial institutions were targeted in 14 April incidents. While major Canadian banks maintain robust defences, smaller financial institutions and credit unions showed greater vulnerability. Several incidents involved compromise of mortgage servicing platforms affecting multiple lenders simultaneously.
Manufacturing
Manufacturing organisations were targeted in 11 April incidents. Operators specifically exploit manufacturing's interconnected production systems, knowing that production downtime directly impacts revenue. Several incidents exploited insecure remote access points installed for supply chain collaboration.
Professional Services
Law firms, accounting firms, and consulting companies were targeted in 8 April incidents. These sectors attract operators because they hold valuable client data, maintain high-value accounts, and have strong financial positions to support ransom payments.
Emerging Vulnerabilities Exploited
In April 2026, ransomware operators actively exploited several vulnerability categories:
- VPN and remote access vulnerabilities: Exploitation of unpatched Citrix, Fortinet, and Cisco vulnerabilities continues to provide initial access. Canadian organisations have shown slow patching for these critical remote access systems.
- Zero-day vulnerabilities: Cl0p and other advanced groups continue to exploit zero-day vulnerabilities in enterprise software, providing temporary advantages before patches are available.
- Ransomware-as-a-Service (RaaS) kits: Affiliate operators continue deploying RaaS kits available on dark web marketplaces, lowering barriers to entry for less sophisticated threat actors.
- Credential compromise: Weak passwords, compromised credentials on dark web marketplaces, and credential reuse continue to be primary initial access vectors.
Defensive Lessons from April Incidents
Backup and Disaster Recovery
Organisations with robust, regularly tested backup systems were able to rapidly recover from ransomware incidents without paying ransom. Specifically, organisations that maintained offline or air-gapped backups were able to recover encrypted data. Conversely, organisations with backup systems on the same network as production systems often found backups encrypted alongside production data.
Network Segmentation
Ransomware propagation was significantly slowed in organisations implementing network segmentation. Several April incidents demonstrated that segmentation limited the scope of compromise, reducing both the value of ransom demands and enabling faster recovery.
Lateral Movement Prevention
Organisations implementing zero trust principles and strict access controls experienced reduced lateral movement following initial compromise. EDR (Endpoint Detection and Response) tools proved critical for detecting and containing active threats.
Canadian Regulatory Context
Canadian organisations dealing with ransomware incidents must navigate several regulatory frameworks:
- PIPEDA: Mandatory breach notification for incidents affecting personal information. Many ransomware incidents trigger PIPEDA obligations.
- OSFI: Financial institutions must report significant cyber incidents to the Office of the Superintendent of Financial Institutions.
- Critical Infrastructure: Operators of critical infrastructure must report significant incidents to the Canadian Centre for Cyber Security.
- Provincial Regulations: Various provincial privacy laws may impose additional reporting requirements.
Ransom Payment Considerations
Canadian organisations should be aware that ransomware payments may violate Canadian sanctions regulations if funds are transferred to sanctioned jurisdictions or designated terrorists. Many ransomware operators operate from or channel funds through Russia, Iran, or North Korea—all subject to OFAC and Canadian sanctions.
The Canadian government continues to discourage ransom payments. However, in practice, many affected organisations consult with law enforcement and insurance providers before making payment decisions.
