Introduction
Ransomware remains one of the most persistent and adaptive cyberthreats. As of 2026, cybercriminals are leveraging new tactics such as post-quantum cryptography, encryptionless extortion, and advanced evasion techniques. While overall attack rates have slightly declined, the risks remain high—especially for the manufacturing sector, which suffered over $18 billion in losses in the first three quarters of 2025. This guide provides a step-by-step approach to bolster your defenses against the modern ransomware landscape. Use the internal links to jump to specific steps.
What You Need
- Security information and event management (SIEM) or endpoint detection and response (EDR) tool – to monitor and respond to threats.
- Access to threat intelligence feeds – for updates on ransomware families and IOCs.
- Backup infrastructure – offline or immutable backups.
- Vulnerability management platform – to track and patch CVEs.
- Training materials – for employee awareness programs.
- Incident response playbook – updated for 2026 threats.
- Budget for security upgrades – especially for quantum-safe encryption and remote access controls.
Step-by-Step Guide
Step 1: Assess your current cybersecurity posture
Start by evaluating your organization’s existing defenses. In 2026, initial access brokers are actively targeting RDWeb (Remote Desktop Web Access) as their preferred entry point. Review your remote access policies: ensure multi-factor authentication is enforced, and limit RDWeb exposure to only necessary users. Conduct a risk assessment to identify where your security gaps lie—especially around endpoint protection, identity management, and backup integrity. Use the Tips section for additional assessment criteria.
Step 2: Strengthen endpoint defenses against EDR killers and BYOVD
Ransomware operators now routinely deploy EDR-killer tools and use the Bring Your Own Vulnerable Driver (BYOVD) technique to disable security software. To counter this, implement a layered endpoint security strategy:
- Use EDR solutions that have built-in driver blocklisting and can detect anomalous driver loads.
- Enable Windows Defender Application Control or similar features to prevent untrusted drivers.
- Regularly update your security software’s signature database and behavior analytics.
- Deploy a dedicated EDR bypass detection tool that monitors for common evasion tactics (e.g., process termination attempts, registry changes).
Conduct red-team exercises to test your environment against known EDR-killer toolkits. Document findings and adjust detection rules accordingly.
Step 3: Prepare for post-quantum cryptography (PQC) threats
In 2026, advanced ransomware families like PE32 are already using the ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism) standard. This quantum-resistant encryption makes decryption impossible without the private key. To prepare:
- Inventory your encrypted data assets and classify by sensitivity.
- Begin migrating to quantum-safe encryption algorithms (e.g., NIST-approved PQC standards) for sensitive data at rest and in transit.
- Ensure your backup encryption also supports PQC, or store backups in an offline, air-gapped format to avoid cross-contamination.
- Monitor threat intelligence for new PQC ransomware strains to update detection signatures.
Note that even if you cannot fully migrate yet, having a plan and timeline reduces the impact of a quantum-assisted ransomware attack.
Step 4: Address encryptionless extortion attacks
As ransom payments drop, some groups are shifting to pure data theft and extortion without encrypting files. This tactic relies on stealing sensitive data and threatening to release it. Mitigate this risk by:
- Implementing strict data loss prevention (DLP) policies to monitor and block unauthorized data exfiltration.
- Using data sealing (e.g., creating cryptographic hashes of files) to detect tampering and prove authenticity to law enforcement.
- Educating employees about the consequences of data leaks and reinforcing the importance of not sharing credentials.
- Developing a crisis communication plan that includes legal, PR, and technical teams to handle extortion threats without paying.
Encryptionless attacks often fly under the radar because there is no classic ransomware payload. Strengthen your data visibility – know what data flows where and who has access.
Step 5: Harden remote access against initial access brokers
Initial access brokers are increasingly focusing on RDWeb. To shut down this vector:
- Replace RDWeb with a VPN-less zero trust network access (ZTNA) solution that authenticates each session.
- If using RDWeb, enforce conditional access policies (e.g., device compliance checks, geo-fencing).
- Regularly audit active RDWeb sessions and revoke unused accounts.
- Monitor for brute-force attempts and anomalous login patterns using automated SOAR playbooks.
Remember that brokers also leverage other remote access tools; apply the same controls to all internet-facing services.
Step 6: Stay informed and collaborate
Ransomware trends evolve rapidly – new families emerge, and tactics shift. Participate in information sharing communities (e.g., ISACs, Kaspersky’s annual reports, Anti-Ransomware Day events on May 12). Regularly review threat intelligence feeds for IOCs related to the latest ransomware families. Always keep your incident response plan updated to include procedures for quantum-assisted attacks, EDR bypass, and data extortion.
Tips for Success
- Defense in depth: Never rely on a single security layer. Combine EDR, network segmentation, email filtering, DLP, and strong authentication.
- Backup, backup, backup: Maintain immutable offline backups and test restoration regularly.
- Employee training: Social engineering remains the top entry point. Run phishing simulations and ransomware awareness sessions annually.
- Zero trust architecture: Assume breach. Verify every access request, even from inside your network.
- Legal preparation: Have a relationship with law enforcement (e.g., FBI, cyber units) and a legal team experienced in ransomware extortion.
- Don’t pay: Paying ransoms funds criminal operations and does not guarantee data recovery. Invest those funds in prevention instead.
