In a bold step toward more precise cyber threat tracking, researchers from Cisco Talos, in partnership with The Vertex Project, have introduced an upgraded analytical framework designed to decode the increasingly fragmented nature of modern cyberattacks. This innovation directly addresses a growing challenge in cybersecurity: attacks no longer stem from single, unified actors but are often carried out by multiple, loosely connected threat groups, each managing different phases of an operation.
This collaborative shift is not just a trend — it’s redefining the playbook of cyber defense. Traditional models like the Diamond Model of Intrusion Analysis and the Cyber Kill Chain are struggling to keep pace. To close this analytical gap, Cisco Talos and The Vertex Project have enhanced the Diamond Model by introducing a new “Relationship Layer.” This addition provides deeper insights into how threat actors interact, share tools, and transfer access, transforming how cyber defenders understand and respond to complex, multi-party cyberattacks.
The Evolution of Threat Attribution: Breaking Down the
Cisco Talos, in collaboration with The Vertex Project, has launched a refined threat analysis model aimed at addressing a crucial evolution in cyberattack strategies. Cyberattacks are increasingly segmented, with distinct threat actors handling different parts of the kill chain — from the initial breach to data exploitation and ransom monetization. These fragmented campaigns often involve operational outsourcing and shared tooling, complicating traditional profiling and response strategies.
Historically, cybersecurity experts have relied on the Diamond Model and the Cyber Kill Chain to trace attacks and identify adversaries. While effective in single-actor scenarios, these models falter when applied to modern attacks where multiple groups, often unknown to one another, coordinate indirectly. For instance, one group may breach a system and sell access to another, who then launches ransomware. Misattribution becomes likely, and critical patterns go unnoticed.
To bridge this analytical shortfall, Cisco Talos and The Vertex Project introduced the “Relationship Layer” into the Diamond Model. This enhancement allows analysts to track interactions between actors — such as buying infrastructure or transferring access — offering a clearer understanding of how campaigns unfold across organizational boundaries.
One compelling example is the ToyMaker campaign. Here, a financially driven group first gained access to a corporate network and later transferred control to the Cactus ransomware group. Despite using different techniques and tools, the shared credentials linked the actors. Without the Relationship Layer, analysts might have mistakenly identified them as a single entity. With it, they accurately mapped the flow of activity, enhancing attribution and enabling more precise defensive actions.
This model not only improves visibility but also strengthens early detection. Analysts can now detect suspicious handovers, backdoor deployments, and access sales — elements often missed in classical models. In a world where cybercrime has become commoditized and specialization thrives, this layered approach provides essential clarity and agility.
What Undercode Say:
The introduction of the Relationship Layer marks a pivotal development in the evolution of threat modeling and cyber defense strategy. Traditional models like the Diamond Model and the Cyber Kill Chain assume a linear, often centralized actor structure. These assumptions, while once valid, are increasingly obsolete in the face of modern cybercrime ecosystems.
What Cisco Talos and The Vertex Project have achieved with this enhancement is not merely an academic upgrade but a practical recalibration of how threat actors are understood. Cyberattacks today are more akin to joint ventures than solo missions. This decentralization, or compartmentalization, means multiple threat groups are involved, each with distinct roles, tools, and motivations.
The Relationship Layer contextualizes the relationships between these entities, exposing vital transactional or cooperative patterns. It’s not just about who attacked — it’s about who enabled, facilitated, or benefited from that attack. This subtlety allows analysts to understand campaigns not only by their outcomes but by their architecture.
Moreover, this shift aligns perfectly with trends in cybercrime-as-a-service (CaaS). Many actors now specialize: one group gains access, another develops payloads, and yet another monetizes the breach. These transactional relationships often evade traditional detection methods. With the new layer, analysts can better trace these business-like operations across the digital black market.
The ToyMaker case is a textbook example. Before the Relationship Layer, such a campaign might have appeared disjointed or even unconnected. Now, it’s seen for what it is — a coordinated relay race of malicious actors passing the baton. This understanding is invaluable for prioritizing response and shaping preventive strategies.
In practice, security teams can leverage this model to identify weak points in their defenses where actor handovers typically occur. This opens up new possibilities for early interventions, such as blocking known access brokers or detecting handover indicators. It also facilitates better intelligence sharing among cybersecurity teams, who now speak the same analytical language.
The model also enhances attribution accuracy. Attribution is a contentious and often politicized area of cybersecurity. A better understanding of actor relationships can shield analysts from jumping to conclusions and instead focus on actionable patterns and indicators.
Lastly, this model fosters proactive defense. Rather than waiting for ransomware to hit, defenders can now look for early warning signs — unusual remote access patterns, sudden credential sharing, or infrastructure reuse — and act swiftly. In essence, the Relationship Layer doesn’t just help you understand the attack after the fact; it empowers you to predict and possibly prevent it.

Prediction 🔮
As cybercrime continues to mimic business ecosystems with specialized actors and outsourced operations, the demand for tools like the enhanced Diamond Model will surge. Security vendors and enterprise SOCs (Security Operations Centers) are likely to integrate similar relationship-mapping technologies into their platforms. Expect future threat intelligence platforms to focus more on relationship dynamics rather than isolated events, providing a deeper, more contextualized understanding of attack flows.
