Structuring raw data into usable formats, often utilizing frameworks like STIX/TAXII.
Focuses on the tactics, techniques, and procedures (TTPs) of threat actors. It helps defenders understand how attackers operate.
Tactical CTI maps the specific methodologies used by threat actors. This layer primarily details Tactics, Techniques, and Procedures (TTPs) aligned with frameworks like MITRE ATT&CK. Tactical intelligence helps security teams understand how an adversary operates, allowing engineers to build robust, behavior-based detection rules rather than relying on static signatures.

To implement practical threat intelligence and data-driven threat hunting, organizations should follow these steps: Tactical CTI maps the specific methodologies used by
Strategic CTI provides high-level overviews for executive decision-makers and Chief Information Security Officers (CISOs). It focuses on long-term trends, geopolitical risk factors, and evolving adversarial motivations. This data influences budget allocations, organizational risk management, and overall security architecture investments. Tactical Intelligence
Process hollowing is a common defense evasion technique where an attacker spawns a legitimate process (like svchost.exe ) in a suspended state, hollows out its memory, and replaces it with malicious code. Hunt Objectives Operational (Technical) Intelligence 5
Grouping similar data points (like process execution arguments) and sorting them by frequency. The rarest entries often represent malicious activity.
If the hunt uncovers a security incident, the forensics reveal new infrastructure, tools, or indicators unique to that actor. These internal discoveries are fed back to the CTI team to enrich their custom intelligence database and optimize overall corporate defense strategies.
