Ransomware attacks are projected to occur every 2 seconds by 2031, up from every 11 seconds in 2021. Organizations paid approximately $813.55 million to ransomware groups in 2024. Email remains the primary attack vector, with malicious attachments twice as common as phishing links. Organizations with compromised backups face $3M average recovery costs, with 45% requiring more than a month to recover. Active ransomware groups increased 55% from Q1 2023 (29) to Q1 2024 (45).
Ransomware Attack Methodology: MITRE ATT&CK Framework
Modern ransomware attacks follow a systematic approach:
- Reconnaissance: Information gathering about target systems
- Resource Development: Creating tools and establishing infrastructure
- Initial Access: Entry via phishing, vulnerabilities, compromised credentials
- Execution: Running malicious code in the target environment
- Persistence: Establishing backdoors for sustained access
- Privilege Escalation: Gaining higher system permissions
- Defense Evasion: Bypassing security controls
- Credential Access: Stealing authentication credentials
- Discovery: Mapping environment for valuable assets
- Lateral Movement: Spreading through network
- Collection: Gathering sensitive data
- Command and Control: Establishing communication channels
- Exfiltration: Transferring data to attacker-controlled locations
- Impact: Deploying ransomware encryption

Key Fidelis Elevate XDR Capabilities
Comprehensive Visibility and Contextual Mapping
- Fidelis Elevate provides continuous cyber terrain mapping and risk analysis, enabling organizations to maintain a real-time inventory of all assets-including managed and unmanaged devices, network traffic across all ports and protocols, and cloud resources.
- Patented Deep Session Inspection® delivers granular content and context beyond standard netflow, eliminating blind spots and enhancing network data loss prevention (DLP).
Integrated Deception Technology
- The platform employs deception techniques such as traps, decoys, and breadcrumbs to lure attackers, reveal their presence, and divert them from real assets.
- Deception is dynamically deployed, increasing attacker costs and risks while giving defenders the advantage to study attacker behavior and fortify defenses.
Unified Detection and Response Across Domains
- Fidelis Elevate integrates mature network, endpoint, and deception capabilities, offering holistic visibility and control across networks, endpoints, cloud, and users.
- Real-time and retrospective analysis on rich metadata enables detection and response at every step of the attack kill chain, including advanced threats and lateral movement.
Active Directory Defense
- The platform uniquely provides comprehensive Active Directory defense, identifying misconfigurations, monitoring for exploitation (e.g., brute force, abnormal ticket requests), and offering remediation interfaces.
Automated, Contextual Threat Detection and Response
- Automated defenses detect and alert in real-time, with instrumentation and monitoring across all environments (on-premises, cloud, hybrid).
- Automated playbooks and AI/ML-powered detections accelerate investigation, containment, and recovery.
Open XDR Architecture and Integration
- Fidelis Elevate is an open XDR solution, supporting integration with third-party EDR and security tools, preserving existing security investments and enabling flexible, tailored deployments.
- The CommandPost interface centralizes security configuration, management, and retrospective analysis.
Proactive Threat Hunting and Intelligence
- The platform leverages MITRE ATT&CK mappings, threat intelligence, and machine learning for predictive analysis, enabling proactive threat hunting and early-stage ransomware detection.
