Ransomware Trends Targeting Defense Contractors: What You Need to Know
Ransomware isn’t a new threat, but the data from the past year makes it clear it isn’t fading either. For defense contractors, the question has moved past whether ransomware is a relevant risk. It’s whether your organization could detect an intrusion early, contain it quickly, and keep operating while it recovers.
This report looks at the ransomware trends defense contractors face in 2026, why the defense supply chain remains an attractive target, and the monitoring and response practices that reduce the damage when an attack gets through.
The Ransomware Trends Defense Contractors Should Watch in 2026
Ransomware Is Present in Nearly Half of All Breaches
According to Verizon’s 2026 Data Breach Investigations Report, ransomware grew again to 48% of all breaches, up from 44% the previous year. The incidents in the 2026 edition took place between November 1, 2024, and October 31, 2025, so these figures describe the most recent full year of data. Verizon
There is a counterpoint worth noting. Ransom payments continued to decline in the dataset, as 69% of ransomware victims didn’t pay, and the median ransom paid fell to $139,875 from $150,000 the previous year. Fewer payments, however, don’t mean smaller losses. The operational cost of downtime and recovery often exceeds the ransom itself. Verizon
Industrial Organizations Remain Heavily Targeted
Manufacturing sits at the center of this picture. In Q1 2026, Dragos identified 1,020 ransomware incidents impacting industrial organizations worldwide, with manufacturing the most heavily impacted sector at 633 claimed victim organizations. In Q2 2026, the count rose to 1,140 incidents, a 12% increase over Q1. Dragos
Notably, Dragos found attackers typically disrupt operations via the loss of enterprise IT systems, ERP platforms, and virtualization infrastructure, versus direct manipulation of control systems. Production stops because the business systems running it go down. Dragos
Attackers Are Getting In Through Vulnerabilities and Credentials
How attackers gain entry is shifting. Vulnerability exploitation has overtaken stolen credentials as the most common way attackers gain initial access, the first time credential theft has been knocked off the top spot in the report’s 19-year history. Remediation isn’t keeping pace: only 26% of critical vulnerabilities were fully remediated by organizations in 2025, a drop from the previous year’s 38%. Help Net Security
Credentials still matter enormously. An analysis of the same DBIR data highlights that 50%of ransomware victims had a credential or infostealer event occur within 95 days prior to the ransomware attack. Dragos similarly observed ransomware operators relying on exploitation of internet-facing edge devices and remote management tooling, abuse of valid accounts, and credential theft. Push Security
Third-Party Exposure Keeps Climbing
Breaches with third-party involvement increased by 60% from last year’s dataset, reaching 48% of total breaches. For contractors embedded in multi-tier supply chains, a vendor’s weakness can become your incident. Verizon
Why Ransomware Targets the Defense Supply Chain
Defense contractors can be attractive targets for several overlapping reasons:
Sensitive information
Contractors handle CUI, technical data, and proprietary business information that carries value to both criminal and nation-state actors.
Supply chain connectivity
Compromising a supplier can provide a path toward larger organizations in the same ecosystem.
Limited internal resources
Small and mid-sized contractors often run lean IT teams without dedicated security staff or round-the-clock monitoring.
Operational pressure
Production schedules and contractual deadlines raise the cost of downtime, which attackers count on.
Size alone offers no protection. Google Threat Intelligence’s Luke McNamara noted that the reality is that threat actors are targeting the entire defense ecosystem, from massive prime contractors down to startups building niche products. Help Net Security
That said, exposure varies. An organization’s specific risk depends on its systems, data, access paths, and security maturity, which is why generalized threat data is a starting point rather than a verdict.
The Real Cost of a Ransomware Incident
The ransom demand is rarely the largest cost. A serious incident can bring:
Loss of access to critical systems
including ERP, scheduling, and file servers
Production and operational disruption
that ripples into delivery timelines
Exposure of sensitive information
particularly in double-extortion attacks where data is stolen before systems are encrypted
Recovery costs and extended downtime
Production schedules and contractual deadlines raise the cost of downtime, which attackers count on.
Delayed contractual work
and strained customer relationships
Investigation and remediation effort
to confirm the threat is fully removed
Reporting and contractual obligations
including DFARS 252.204-7012’s requirement to report cyber incidents affecting covered defense information to the DoD within 72 hours of discovery
Detection Matters: The Role of EDR and XDR
The earlier suspicious activity is detected, the more options remain for containing it. Ransomware attacks typically unfold over days or weeks before encryption begins: initial access, credential gathering, lateral movement, and data staging. Each stage leaves signals.
Endpoint Detection and Response (EDR) monitors laptops, servers, and workstations for suspicious behavior that traditional antivirus misses, such as unusual process activity or attempts to disable security tools. Extended Detection and Response (XDR) broadens that visibility by correlating activity across endpoints, network, cloud, and identity systems, surfacing attack patterns that look harmless in isolation.
Together, they help organizations identify indicators of compromise, investigate alerts in context, and respond faster. But tools only generate signals. Someone needs to review, validate, and act on them, which is the gap many smaller contractors struggle to fill.
DataSure24’s EDR & XDR Monitoring pairs detection technology with analysts who monitor, triage, and escalate alerts, so suspicious activity gets attention rather than accumulating in a dashboard.
When an Attack Happens: Why Incident Response Matters
Detection is only part of readiness. When an incident occurs, the first hours determine how much damage follows, and those hours shouldn’t be spent working out who to call.
Prepared organizations have in place:
- A documented incident response process
- Defined roles and responsibilities
- Escalation procedures with named contacts
- Containment procedures for isolating affected systems
- Communication protocols, internal and external
- Investigation and remediation processes
- Recovery planning built around tested backups
- Post-incident review to capture lessons learned
DataSure24’s Incident Response as a Service gives organizations a retained relationship with a response team that knows the environment before an incident, along with plan development and tabletop testing to make sure the plan works when it’s needed.
Ransomware Readiness Checklist for Defense Contractors
Use these questions as a practical starting point:
Do we know which systems and data are most critical to operations?
Are security alerts actively monitored, including outside business hours?
Are endpoint protections deployed and maintained across all in-scope systems?
Have backups been tested through actual restoration?
Do we have documented incident response procedures?
Does everyone know who is responsible during an incident?
Can we quickly identify and isolate affected systems?
Have we practiced our response through a tabletop exercise?
Do we know how incidents must be escalated, documented, and reported?
Have we reviewed our response capabilities in the past year?
Building a More Resilient Defense Contractor Security Program
Ransomware readiness overlaps substantially with the security responsibilities contractors already carry under NIST SP 800-171 and CMMC, including incident response, audit logging, system monitoring, and vulnerability management. Strengthening monitoring and response capability supports that broader program, though no single service establishes compliance on its own. The goal is effective, consistently operated security practices.
How DataSure24 Helps
Monitoring helps identify potential threats. Incident response helps organizations know what to do when one gets through. DataSure24 brings both together, with EDR & XDR Monitoring for visibility and IRaaS for structured response, backed by a team experienced in the CMMC and NIST requirements defense contractors work within.
