In collaboration with Center Participants, the Center for Threat-Informed Defense (Center) is building a library of adversary emulation plans to allow organizations to evaluate their defensive capabilities against the real-world threats they face. Emulation plans are an essential component in testing current defenses for organizations that are looking to prioritize their defenses around actual adversary behavior. Focusing our energies on developing a set of common emulation plans that are available to all means that organizations can use their limited time and resources to focus on understanding how their defenses actually fare against real-world threats.
Also see our recent blog on the Adversary Emulation Library.
Available adversary emulation plans are listed below:
|Emulation Plan||Intelligence Summary|
|FIN6||FIN6 is thought to be a financially motivated cyber-crime group. The group has aggressively targeted and compromised high-volume POS systems in the hospitality and retail sectors since at least 2015...|
|APT29||APT29 is thought to be an organized and well-resourced cyber threat actor whose collection objectives appear to align with the interests of the Russian Federation...|
|menuPass||menuPass is thought to be threat group motivated by collection objectives, with targeting that is consistent with Chinese strategic objectives...|
|Carbanak Group||Carbanak is a threat group who has been found to manipulate financial assets, such as by transferring funds from bank accounts or by taking over ATM infrastructures...|
|FIN7||FIN7 is a financially-motivated threat group that has been associated with malicious operations dating back to late 2015. The group is characterized by their persistent targeting and large-scale theft of payment card data from victim systems...|
These adversary emulation plans are based on known-adversary behaviors and designed to empower red teams to manually emulate a specific threat actor in order to test and evaluate defensive capabilities from a threat-informed perspective. This approach empowers defenders to operationalize cyber threat intelligence to better understand and combat real-world adversaries. Rather than focusing on static signatures, these intelligence-driven emulation plans provide a repeatable means to test and tune defensive capabilities and products against the evolving Tactics, Techniques, and Procedures (TTPs) of threat actors and malware.
Adversary emulation enables organizations to view their security through the eyes of a cyber adversary with the goal of improving defenses across the adversary’s lifecycle. As defenders this expands our attention and focus beyond just the final actions of the adversary achieving their operational objective to rather understand and appreciate every distinct behavior (that could have been detected and/or mitigated) leading up to that point.
Each emulation plan is rooted in intelligence reports and other artifacts that capture and describe breaches and campaigns publicly attributed to a specific named threat actor. To develop each plan, we research and model each threat actor, focusing not only on what they do (ex: gather credentials from victims) but also how (using what specific tools/utilities/commands?) and when (during what stage of a breach?). We then develop emulation content that mimics the underlying behaviors utilized by the threat actor (i.e. not an exact representation, rather capturing the pertinent elements that accurately generate appropriate test telemetry for defenders). This approach results in nuanced emulation plans, each capturing unique scenarios and perspectives that we can leverage as threat-informed defenders.
As is the case with traditional red teaming and penetration testing, adversary emulation is a specific style of offensive assessment performed to help us test and tune our defenses. In this case, our objective is to operationalize cyber threat intelligence describing behaviors observed in specific campaigns or malware samples. From this intelligence, we select and execute a subset of behaviors (and their variations) to assess our defenses from the perspective of the specific threat.
As described in the next section, each emulation plan captures specific threat scenarios. These scenarios can be executed end-to-end, or individual behaviors can be tested. Organizations can also choose to further customize the scenarios and/or behaviors within each emulation plan to better fit their specific environment, priorities, or to be shaped by additional intelligence.
In summary, each emulation plan should be perceived as input to an offensive assessment/red team. The content can be used as strict instructions to follow, or as just a starting point to be built upon and personalized.
Each emulation plan focuses on a specific named threat actor. The README of each individual plan provides a curated summary of available cyber threat intelligence, composed of an intelligence overview of the actor (describing who they target, how, and why where possible) as well as the scope of their activity (i.e. breadth of techniques and malware used). All presented information is cited back to relevant publicly available cyber threat intelligence and communicated and annotated via ATT&CK.
Within each emulation plan, the operational flow provides a high-level summary of the captured scenario(s). These scenarios will vary based on the adversary and available intelligence, but typically follow a sequential progression of how the actor breaches then works towards achieving their operational objectives within a victim environment (espionage, data/system destruction, etc.).
The content to execute the scenario(s) is broken down into step-by-step procedures provided in both human and machine-readable formats. Scenarios can be executed end-to-end or as individual tests. The human-readable formats provide additional relevant background where possible as well as any setup prerequisites, while the machine-readable format is designed to be programmatically parsed (ex: read, reformatted, and ingested into an automated agent, such as CALDERA and/or breach simulation frameworks).
Detailed documenation for our emulation plan structure can be found here.
The threat landscape changes every day, as new groups/malware emerge and known adversaries adapt and evolve. The Center will continue to populate and maintain this library to match this growth curve through dedicated research efforts that aim to either create or update plans based on a specific adversary.
