Understanding who might attack your organization and what they are capable of is a critical step in advanced threat analysis. This guide helps you evaluate threat communities, their technical capabilities, and their motivations so you can build an accurate, actionable threat model.
The Threat Modeling Process
To accurately assess threat actors, you first need to understand the broader threat modeling lifecycle. This ensures you are testing the most relevant controls and processes rather than just running down a generic IT checklist.
- 1
Gather documentation
Collect relevant system architecture, business process documentation, and open-source intelligence (OSINT) about your organization.
- 2
Identify assets
Categorize your primary assets (e.g., a customer database) and secondary assets (e.g., an HR database on the same server that could be used as a stepping stone).
- 3
Identify threat communities
Determine which internal and external groups pose a risk to your specific environment.
- 4
Map threats to assets
Connect the identified threat communities to your primary and secondary assets to reveal potential attack vectors.
Identifying Threat Communities
Threat actors are generally categorized by their location relative to your organization: internal or external. Whenever possible, identify specific actors; otherwise, outline general communities based on your industry and intelligence.
| Internal Threats | External Threats |
|---|---|
| Employees & Contractors | Business Partners & Suppliers |
| Executive & Middle Management | Competitors |
| Network & System Administrators | Nation States |
| Developers & Engineers | Organized Crime |
| Remote Support Technicians | Hacktivists & Script Kiddies |
A note on employees: General employees are typically not severe threats, as they rely on the company for their livelihood. Most employee-related incidents involve accidental data loss. However, they can occasionally be coerced by outsiders or act maliciously on their own (e.g., a rogue trader).
Threat Capability Analysis
Once you have identified a threat community, you must analyze their technical capabilities. This determines the actual probability that they can successfully compromise your organization.
1. Tools in use
Evaluate the tools available to the threat actor. Consider both proprietary tools they might possess and freely available tools. Assess the skill level required to use these tools effectively.
2. Exploits and payloads
Analyze the group's ability to obtain or develop exploits relevant to your environment. Do they have the resources to purchase zero-days from underground communities, or are they relying on publicly available exploit kits?
3. Communication mechanisms
Understand how the threat actor communicates and controls their attacks. This ranges from simple encryption to specialized services like bulletproof hosting, drop-sites, and botnets.
Testing C2 Detection: Penetration testers are uniquely positioned to test an organization's ability to detect Command and Control (C2) channels. Try creating malware specimens with increasing levels of obfuscation to see exactly when your detection mechanisms fail.
4. Accessibility
Factor in how close the threat actor can get to your organization or specific assets. Do they have physical access? Do they have a valid, unprivileged account? Accessibility heavily influences the complexity of the attack scenarios you need to prepare for.

Attackers are driven by different goals, and their motivations constantly evolve. Understanding why an actor might target you helps predict what they will target and how far they will go.
Common motivations include:
Profit: Direct financial theft, ransomware, or selling corporate data.
Hacktivism: Ideological attacks aimed at disrupting operations or defacing public assets.
Direct Grudge: Disgruntled former employees or dissatisfied customers seeking revenge.
Fun / Reputation: Script kiddies or recreational hackers looking for bragging rights.
Stepping Stone: Gaining access to your systems solely to attack a partner or connected system.
To validate your threat model, look at comparable organizations within your industry vertical. Analyzing recent breaches or incidents they have faced provides a realistic baseline for the threats you are likely to encounter.
Mapping Capabilities to Targets
Understanding a threat actor's capabilities is only useful when mapped against what they want to steal or disrupt.
Organizational Data Targets
Threat actors frequently target specific data types based on their motivations. This includes product trade secrets, financial accounts, marketing roadmaps, and technical infrastructure designs (like system configurations or privileged credentials).
Human Asset Targets
Attackers leverage human assets to divulge information or manipulate decisions. Targets aren't always executives; they are often administrative assistants, technicians, or HR personnel who hold the keys to critical systems or physical access.
Business Process Targets
Attackers look for flaws in the value chain. By mapping out critical vs. non-critical business processes (and the IT infrastructure supporting them), you can see exactly how a specific threat community might cause financial loss.
