IOC (Indicator of Compromise)

Forensic evidence on a network or device that indicates a computer breach or malicious activity has occurred.

Overview

Indicators of Compromise (IOCs) are the digital breadcrumbs left behind by attackers. They include malicious IP addresses, newly registered domains, file hashes, and specific email subject lines. The faster an organization can identify and share IOCs, the faster it can block an attack. PhiShark excels at real-time IOC generation. When its Agentic AI validates a novel phishing site, it instantly extracts the full attack infrastructure—the IP, the hosting provider, the drop-zone email—and generates high-fidelity IOCs that can be automatically fed into the organization's SIEM or firewalls.

Real-World Examples

  • A specific malicious URL used in a credential harvesting campaign
  • The IP address of a command and control (C2) server
  • An MD5 hash of a malicious payload
