In cybersecurity, we often treat vulnerabilities, those officially documented CVEs, as the core of the problem. But ask any incident response team what led to the last major breach, and chances are it wasn’t just an unpatched CVE, it was an exposure. Misconfigurations, forgotten SaaS tokens, orphaned assets, or overly permissive cloud roles often paved the way. Ransomware operators know this. And in 2024, they didn’t just exploit vulnerabilities, they exploited the entire exposure surface.
The Exposure Mindset: A Hacker’s Advantage
According to HiveForce Labs’ Annual Threat Report 2025, only 0.6% of the nearly 40,000 vulnerabilities disclosed in 2024 were actually exploited in the wild. That’s fewer than 250 CVEs. And yet ransomware incidents reached an all-time high: 5,770 attacks, up 21% from the previous year.
So how are attackers breaching so many systems?
They’re exploiting exposure:
- Token theft from CI/CD pipelines and OAuth integrations.
- Misconfigured cloud buckets with open permissions.
- Unmonitored SaaS applications with admin-level access.
- Unpatched systems with default credentials.
These are invisible weaknesses, until they’re not.
Chained Exploits: The Anatomy of Exposure Abuse
Let’s look at a real-world example: the ConnectWise ScreenConnect flaws (CVE-2024-1708 and 1709). Within 22 minutes of the proof-of-concept exploit being published, attackers were already executing ransomware payloads.
These vulnerabilities allowed access and enabled unauthenticated remote code execution. Ransomware operators like LockBit, Cl0p, and BlackCat chained these flaws with credential theft and lateral movement to compromise entire networks.
This is the new playbook:
- Initial access via exposed interfaces or stolen tokens.
- Privilege escalation using scripting interpreters like PowerShell.
- Payload deployment through validated command execution.

Why Traditional VM Is No Longer Enough
Traditional vulnerability management (VM) treats all CVEs equally. It’s reactive, based on severity scores and patch cadence. But threat actors don’t care at all about CVSS as they care about what’s exposed, exploitable, and valuable.
That’s why ransomware actors:
- Exploit weak authentication systems before CVEs are even patched.
- Target misconfigurations and identity flaws, not just software bugs.
- Use access brokers who sell stolen session tokens, bypassing technical vulnerabilities entirely.
This is why Threat Exposure Management (TEM) is rising. It considers risk in context: asset criticality, adversary behavior, exploitability, and exposure windows.
The New Metrics That Matter
To move beyond checklists and toward resilience, defenders need to track:
- Mean Time to Risk Reduction (MTTRR) and not just MTTR.
- Exposure Debt based on how long high-risk systems remain exposed.
- Threat-Informed Prioritization based on PoCs, TTPs, and real-world exploitation.
Because when an exploit lands in a ransomware affiliate’s hands, they don’t wait. They chain, move laterally, and extort with precision.
Recommendations: Shrink Exposure, Not Just Patch Counts
To reduce ransomware impact:
- Integrate CAASM (Cyber Asset Attack Surface Management) to continuously discover unmanaged assets and shadow IT.
- Use adversarial validation tools (e.g., Breach and Attack Simulation) to verify if controls work in practice.
- Prioritize exposures with exploit kits and PoCs available beyond just findings based on CVSS.
- Harden identity systems like OAuth, SSO, and tokens are the new kill chain.
- Map exposures to business services to tie cyber risk to operational risk.
Conclusion: We’re Not in CVE-Land Anymore
The ransomware economy has matured. It doesn’t wait for NVD listings. It doesn’t need sophisticated zero-days. All it needs is exposure: your exposed APIs, your forgotten cloud workload, your unmanaged credentials.
To defend against it, organizations must match that mindset. Fixing vulnerabilities helps, but reducing exposure is what actually stops breaches.
