Triage IOFA in a High-Volume SOC

Prev Next

A U.S. healthcare provider faced ransomware precursors flooding EDR logs in late 2024. Manual triage of Indicators of Future Attack (IOFA™) averaged 72 hours per incident, risking HIPAA violations.

Silent Push–powered workflows reduced triage time to under 20 minutes and processed 2,500 Indicators of Future Attack (IOFA™) over 9 months, isolating threats on 600 endpoints.

Two Complementary Workflows

Comprehensive Investigation Workflow

  1. EDR alert → /v2/enrich (risk score)

  2. Score ≥7 → /v2/web-scan (SHV, body hashes)

  3. Cross-check with YARA/VirusTotal

  4. Quarantine + blocklist export

Streamlined Blocklist Workflow

Hourly bulk pull → Enrich only high-score Indicators of Future Attack (IOFA™) → Push to firewalls

Measured Outcomes

  • 2,500 Indicators of Future Attack (IOFA™) processed

  • Triage time reduced from 72 hours to under 20 minutes

  • False-positive rate 3%

  • Averted an estimated $1.2M breach

Silent Push turned raw Indicators of Future Attack (IOFA™) into automated, evidence-based actions at scale.
