Zero-day exploitation
Adversary employs attacks that exploit as-yet-unpublicized vulnerabilities (targeted, based on reconnaissance, or nontargeted), compromising systems before any patch or signature exists.

Connections
- UC-VULN-06 — Verify software, firmware, and information integrity mitigates Zero-day exploitation
- strength
- related
- rationale
- Continuous integrity monitoring surfaces the unexpected changes left by unknown-vulnerability exploitation as adverse events.
- UC-SDLC-04 — Engineer systems with secure architecture and design mitigates Zero-day exploitation
- strength
- primary
- rationale
- Defense in depth, fail-safe defaults and execution-domain isolation limit exploitation of unknown, unpatched vulnerabilities.
- UC-BCDR-16 — Participate in cyber threat intelligence sharing mitigates Zero-day exploitation
- strength
- related
- rationale
- Exchanging IOCs/TTPs gives early warning of novel exploits, but the sharing arrangement feeds detection/blocking rather than itself being the operative zero-day defense.
- UC-ASSET-09 — Receive, analyze, and act on threat and vulnerability intelligence mitigates Zero-day exploitation
- strength
- related
- rationale
- Threat-intel feeds give early IOC/TTP warning of novel exploits, enabling detection before any signature or patch exists.
- UC-VULN-03 — Remediate identified flaws within defined timeframes mitigates Zero-day exploitation
- strength
- related
- rationale
- Time-bound patch deployment shrinks the exposure window once a patch ships for a formerly-unknown vulnerability.
- UC-VULN-05 — Block malware, spam, and phishing across all systems mitigates Zero-day exploitation
- strength
- related
- rationale
- Email/web filtering and behavioral anti-malware block delivery of phishing-borne and novel exploit payloads lacking a signature.
- UC-VULN-08 — Engineer systems to fail predictably and safely mitigates Zero-day exploitation
- strength
- related
- rationale
- On exploit-induced failure, failing to a known safe state preserves security protections and blocks unsafe continuation, limiting impact.
- UC-SDLC-05 — Enforce secure coding and input validation standards mitigates Zero-day exploitation
- strength
- related
- rationale
- Secure coding reduces the count of latent, as-yet-undiscovered vulnerabilities in own code.
- UC-VULN-11 — Embed taint mechanisms to detect data exfiltration mitigates Zero-day exploitation
- strength
- related
- rationale
- Taint activations detect exfiltration from exploitation of unknown vulnerabilities that preventive and signature controls missed.
- UC-VULN-09 — Employ non-persistence and information-resilience techniques mitigates Zero-day exploitation
- strength
- related
- rationale
- Periodic non-persistent refresh evicts adversaries who exploited unknown vulnerabilities, limiting dwell when no patch exists.
- UC-VULN-07 — Harden runtime error handling, output filtering, and memory mitigates Zero-day exploitation
- strength
- primary
- rationale
- DEP/ASLR memory protections block reliable exploitation of unknown memory-corruption vulnerabilities before any patch exists.
