As of May 13, 2025, CyberProof’s most recent public intelligence on the broader threat landscape is its March 5, 2025 Global Threat Intelligence report. That report confirms what defenders already feel in their bones: ransomware remains a dominant and evolving threat, and its dynamics in 2024 set the stage for a more dangerous 2025.

CyberProof’s analysis highlights three features that matter to defense organizations. First, ransomware actors are collaborating with other adversary types and exploiting supply chain relationships to scale impact and reach. Second, attackers continue to mix data theft with encryption to increase extortion pressure and operational impact. Third, exposed infrastructure and unpatched services remain a persistent root cause that gives attackers fast, high value access. These themes are plainly visible in CyberProof’s findings and recommendations for intelligence-driven defenses.

Industry telemetry from other vendors supports and expands that view. Mandiant’s M-Trends 2025 analysis shows that ransomware and extortion accounted for a substantial fraction of incident response work in 2024, with ransomware-related events appearing in a notable share of investigations. The report also emphasizes that vulnerability exploitation and stolen credentials were leading initial access vectors, which shortens the window defenders have to stop ransomware before it deploys. That combination of fast initial access and rapid impact is what makes ransomware especially dangerous for defense and defense-adjacent organizations.

CrowdStrike’s 2025 Global Threat Report amplifies two adjacent risks that matter for defense networks. First, identity-based and malware-free intrusions have risen, meaning attackers increasingly “log in” instead of relying only on noisy malware. Second, generative AI is already amplifying social engineering and operational scale for adversaries. For defense customers, these trends mean perimeter-focused controls alone are no longer sufficient. Visibility into identity, cloud accounts, and partner trust relationships must be elevated to the same operational priority as endpoint hygiene.

Operational impacts are not hypothetical. Sophos’s State of Ransomware research from 2024 shows the financial and recovery burden when organizations are hit: ransom demands and recovery costs climbed dramatically, and attackers frequently attempted to compromise backups to maximize leverage. That pattern is directly relevant to defense contractors, suppliers, and installations that cannot tolerate prolonged downtime or data loss.

What this means in practical terms for defense organizations

1) Treat identity as the primary battlefield. If attackers are increasingly gaining access with stolen credentials or via social engineering, then multi factor authentication that resists phishing, continuous credential hygiene, privileged access governance, and rapid detection of anomalous logins are essential first lines of defense. Visibility and response tooling must cover identity telemetry as thoroughly as endpoint telemetry.

2) Harden the supply chain and remote management surfaces. CyberProof and other vendors document a steady stream of incidents that exploit trusted third parties, remote management tools, and cloud integrations. Defense ecosystems rely on third parties for software, logistics, and operational services. Assume those links will be targeted and enforce least privilege, segmentation, and strict ingress/egress filtering between supplier systems and critical control networks.

3) Assume data theft precedes encryption and protect backups accordingly. Attackers routinely exfiltrate before encrypting. Immutable, offline backups and tested recovery playbooks are non negotiable. Plan for a full extortion scenario that includes public disclosure of stolen data, not just system recovery.

4) Reduce blast radius through segmentation and zero trust. Network segmentation, application allow listing, and strict micro segmentation for operational networks reduce the chances that an initial compromise will escalate into a mission stopping event. Zero trust principles should guide connectivity between business systems and operational technology.

5) Prioritize patching where it matters and validate detection coverage. Mandiant and CyberProof both call out rapid exploitation of high value vulnerabilities and internet-exposed devices. Defense organizations must prioritize remediation for internet-exposed appliances and validate that detections work in real world scenarios by running tabletop exercises and purple team tests.

6) Operationalize threat intelligence and incident playbooks. In a defense context, the cost of confusion is measured in mission risk. Integrate tailored threat intelligence into SOC playbooks, run regular ransomware-specific drills, and make sure legal, procurement, and operations are tabletop tested on whether and how to respond to extortion and disclosure.

A final caution

Ransomware’s business model adapts quickly. Between 2024 and early 2025 the landscape shifted toward faster breakouts, more identity-based access, and greater use of social engineering and third-party vectors. CyberProof’s global report provides a timely framing for those shifts, but defenders in the defense sector should not wait for public reports to act. The attackers are already optimizing for speed and scale. Treat every third party, every backup, every identity, and every internet-exposed appliance as a potential pivot point and plan accordingly.
