The Ransomware Attack Chain

Phase 1: Initial Access (Hours 0-24)

Attackers gain initial foothold through multiple vectors:

Phishing Emails (55% of attacks): Malicious attachments or links delivering initial payload. Common tactics include invoice fraud, shipping notifications, and credential harvesting.

Exposed RDP Services (18% of attacks): Brute force attacks against Remote Desktop Protocol services exposed to internet. Credential stuffing using previously breached password lists.

Vulnerability Exploitation (15% of attacks): Exploiting unpatched vulnerabilities in public-facing applications, VPN gateways, or web servers. Recent campaigns exploited CVE-2024-1709 (ConnectWise ScreenConnect) and CVE-2023-48788 (Fortinet FortiClient EMS).

Trusted Relationships (12% of attacks): Compromising managed service providers, software vendors, or business partners to access multiple victims through trusted channels.

Phase 2: Credential Access and Privilege Escalation (Days 1-3)

Once inside the network, attackers escalate privileges:

• Credential dumping from LSASS memory using Mimikatz or similar tools
• Kerberoasting to extract service account credentials
• NTLM relay attacks capturing authentication traffic
• Exploiting local vulnerabilities for privilege escalation
• Targeting domain administrator accounts for full network control

Phase 3: Discovery and Lateral Movement (Days 3-7)

Attackers map the environment and spread access:

• Network scanning identifying servers, workstations, and critical systems
• Active Directory enumeration mapping user accounts, groups, and permissions
• File share discovery locating sensitive data repositories
• Backup system identification for targeted destruction
• Lateral movement using legitimate tools (PSExec, RDP, PowerShell remoting)

Phase 4: Data Exfiltration (Days 5-10)

Before deploying ransomware, attackers exfiltrate sensitive data for double extortion:

• Identifying high-value data (customer databases, financial records, intellectual property)
• Compressing and staging data for exfiltration
• Transferring to attacker-controlled infrastructure via cloud storage, FTP, or custom protocols
• Typical exfiltration: 50GB-500GB of sensitive data

Phase 5: Defense Evasion and Persistence (Days 7-14)

Attackers prepare for ransomware deployment:

• Disabling endpoint detection and response (EDR) tools
• Deleting or encrypting backup systems
• Clearing event logs to remove forensic evidence
• Establishing multiple persistence mechanisms for re-entry
• Scheduling deployment for maximum impact (weekends, holidays, after-hours)

Phase 6: Ransomware Deployment (Day 14-21)

Final attack phase encrypting systems:

• Simultaneous deployment across all compromised systems
• Encryption of files using AES-256 or similar strong encryption
• Ransom note delivery with payment instructions and deadlines
• Typical encryption time: 2-6 hours for complete network
• Leak site posting threatening public data release if ransom unpaid

Building Your Ransomware Prevention Strategy

1. Email Security and Phishing Defense

Since 55% of ransomware begins with phishing, robust email security is foundational:

Technical Controls:

• SPF, DKIM, DMARC: Email authentication preventing domain spoofing
• Advanced Threat Protection: Sandboxing suspicious attachments and links
• Link Rewriting: Real-time URL analysis protecting against malicious destinations
• Attachment Filtering: Blocking high-risk file types (.exe, .scr, .bat, macro-enabled documents)
• External Email Warnings: Visual indicators for emails from outside organization

User Awareness Training:

• Monthly phishing simulations measuring click rates and reporting behaviors
• Quarterly security awareness training covering latest tactics
• Targeted remediation training for users failing simulations
• Reporting mechanisms making it easy to flag suspicious emails
• Target: <10% phishing simulation click rate, >40% reporting rate

2. Endpoint Protection and Detection

Modern endpoint detection and response (EDR) platforms detect and block ransomware before encryption:

Required EDR Capabilities:

• Behavioral Analysis: Detecting ransomware behaviors (mass file encryption, backup deletion, shadow copy removal)
• Machine Learning: Identifying never-before-seen ransomware variants
• Automated Containment: Network isolation preventing lateral movement
• Rollback Capabilities: Restoring encrypted files from protected local snapshots
• Tamper Protection: Preventing attackers from disabling security agents

Configuration Best Practices:

• Real-time protection enabled on all endpoints (servers, workstations, laptops)
• Cloud-delivered protection for latest threat intelligence
• Controlled folder access protecting critical directories
• Application whitelisting preventing unauthorized executables
• Regular agent health monitoring ensuring continuous protection

3. Network Segmentation and Access Controls

Limiting lateral movement reduces ransomware blast radius:

Segmentation Strategy:

• VLAN Segmentation: Separating user networks from server networks from OT/ICS systems
• Micro-segmentation: Restricting communication between servers to only required services
• Jump Boxes: Controlled access points for administrative activities
• Network Access Control (NAC): Ensuring only authorized, compliant devices access network

Access Control Implementation:

• Principle of least privilege for all accounts
• Privileged Access Management (PAM) for administrative credentials
• Multi-factor authentication (MFA) for all remote access and privileged accounts
• Regular access reviews removing unnecessary permissions
• Service account hardening with complex passwords and restricted permissions

4. Vulnerability Management and Patching

Attackers exploit known vulnerabilities in 15% of ransomware attacks, making timely patching critical:

Patch Management Process:

• Asset Inventory: Complete inventory of all systems, applications, and firmware
• Vulnerability Scanning: Weekly automated scans identifying missing patches
• Risk-Based Prioritization: Focusing on internet-facing systems and critical vulnerabilities
• Patch Testing: Validating patches in test environment before production deployment
• Deployment Timeline: Critical patches within 7 days, high-severity within 30 days

Organizations should implement continuous vulnerability management programs rather than point-in-time assessments.

5. Backup Architecture and Recovery Capabilities

Robust backups are your last line of defense when prevention fails:

3-2-1-1-0 Backup Rule:

• 3 Copies: Production data plus two backup copies
• 2 Different Media: Different storage types (disk, tape, cloud)
• 1 Offsite Copy: Geographically separate location
• 1 Offline/Immutable Copy: Air-gapped or immutable preventing attacker deletion
• 0 Errors: Regular testing validating backup integrity and restorability

Backup Configuration Best Practices:

• Daily incremental backups with weekly full backups
• Retention: 30 days daily backups, 12 months monthly backups
• Separate backup admin credentials from domain admin accounts
• Network segmentation protecting backup infrastructure
• MFA required for backup console access
• Immutable backups with 30-day lock period
