Threat Intelligence

What is Threat Intelligence?

Threat intelligence (TI) is the product of collecting, processing, analyzing, and disseminating information about cyber threats — including threat actors, their motivations, capabilities, tactics, techniques, and procedures (TTPs), and the indicators of compromise (IOCs) they generate. The goal of threat intelligence is to enable security teams to make faster, more informed decisions — anticipating attacks before they occur, detecting them more quickly when they do, and responding more effectively by understanding what the attacker is trying to accomplish. Threat intelligence is classified by type: strategic intelligence for executive decision-making, operational intelligence for security operations, and tactical intelligence (IOCs) for direct detection tool consumption.

Description

Effective threat intelligence programs distinguish between three levels of output. Tactical intelligence — IP addresses, domains, file hashes, YARA signatures — feeds directly into SIEM platforms, endpoint protection, and firewalls as detection signals. This level ages quickly: a malicious IP address may be rotated within hours. Operational intelligence provides context about active campaigns: which threat groups are targeting your industry, what initial access techniques they prefer, and what their attack chain looks like. This intelligence informs threat hunting hypotheses and purple team exercises. Strategic intelligence synthesizes threat trends for CISO and board-level audiences: which adversary groups pose the highest risk to the organization's specific sector and geography, what regulatory changes are coming, and how the threat landscape is shifting. MITRE ATT&CK serves as the universal framework for documenting and sharing threat actor TTPs — enabling organizations to map their detections against known adversary behaviors and identify coverage gaps. Threat intelligence is increasingly powered by AI: automated correlation of massive IOC volumes, natural language processing of threat reports, and predictive models that score vulnerability prioritization signals using current threat actor targeting data.

Usage and Examples

A financial services firm subscribes to a commercial threat intelligence platform that provides sector-specific intelligence. The platform alerts that a threat group known to target financial services is conducting a spear-phishing campaign using AiTM phishing infrastructure and targeting Microsoft 365 tenants. The intelligence includes: specific phishing kit indicators, lookalike domains in use, and TTPS mapped to MITRE ATT&CK. The security team uses this intelligence to: add the identified domains to DNS blocking; tune SIEM detection rules for the specific phishing kit's HTML artifacts; brief employees on the active campaign; and initiate a threat hunting exercise to check whether early-stage activity has already occurred undetected. This proactive response, triggered by intelligence before a successful attack, demonstrates the concrete value of operationalized threat intelligence.

How Does This Relate to Penetration Testing?

Threat intelligence directly informs penetration testing and red team exercises. Intelligence about which threat groups target an organization's sector, what initial access methods they prefer, and what their post-exploitation behavior looks like allows Evolve Security to scope red team engagements as realistic threat simulations rather than generic capability tests. DORA's TLPT (Threat-Led Penetration Testing) mandate explicitly requires that red team scenarios be intelligence-driven, using current threat actor TTPs. Post-engagement, the MITRE ATT&CK techniques used by testers map directly to detection coverage: the client can see exactly which ATT&CK techniques their monitoring detected and which they missed, driving targeted investment in detection engineering. The ATT&CK maturity assessment video from Evolve Security provides a methodology for evaluating ATT&CK coverage. Evolve Security's Red Team engagements use current threat intelligence to simulate the specific adversary groups most likely to target your organization — providing threat-realistic security assurance.
