TETRA:BURST

TETRA:BURST is a collection of five vulnerabilities, two of which are deemed critical, affecting the Terrestrial Trunked Radio (TETRA) standard used globally by law enforcement, military, critical infrastructure, and industrial asset owners in the power, oil & gas, water, and transport sectors and beyond.

Most of the TETRA:BURST vulnerabilities affect all TETRA networks. Depending on infrastructure and device configurations, these vulnerabilities allow for realtime decryption, harvest-now-decrypt-later attacks, message injection, user deanonymization, or session key pinning. Firmware patches are available for some of these vulnerabilities, while compensating controls are recommended for others.

Our Services

Systems & vulnerability research

Understand the inner workings of complex systems, gain insight into vulnerabilities, and identify cost-effective mitigations.

From brand new, highly integrated embedded systems that fit in the palm of your hand to large, geographically dispersed cyber-physical systems running on legacy technology stacks, we’ve got you covered.

Capability development

Building strong in-house capabilities is hard, particularly when it comes to domains requiring a rare intersection of skills. Our capability development services can help you deliver unique results and rapidly build expertise within your organization.

Defensive design

A mature security posture is something which cannot be bolted onto an existing product. However, many products used in critical settings nowadays have their roots in a very different era and struggle to keep up with an evolving threat landscape.

Midnight Blue assists to re-architect such systems in order to ensure secure and future-proof operations.

Our deeply technical offensive expertise and strong background in academic research enable us to not only assist our customers in keeping pace with the increasingly complex threat landscape, but stay ahead of it.

Our researchers have presented numerous talks at top industry conferences such as Black Hat, DEF CON, Chaos Communication Congress, CanSecWest, Infiltrate, OffensiveCon, REcon, hardwear.io and USENIX. In addition, Midnight Blue has served as SME for the industry standard MITRE ATT&CK for ICS framework as well as government commissions and conference review boards.

The way we work

Plan of Approach

We tailor all our services to our clients’ specific needs, and follow a general approach to bring structure to complex and often opaque projects. Depending on the nature of our clients’ needs, we can follow our usual approach or find a more bespoke fit.

01

Intake

Every project starts off with an intake session during which we explore the client’s problem space, identify goals and obstacles and determine a scope.

02

Prestudy

Before an actual plan of approach is drafted we prefer to conduct a prestudy in order to truly understand the problem at hand, decompose it and determine pitfalls and come up with a good estimate on the execution timeframe and technical requirements.

03

Plan of Approach

The output of the prestudy is a plan of approach. It describes the client’s original problem and decomposes it into manageable and clear goals, obstacles and scoping. In addition, it provides an execution timeframe, technical requirements and a step-by-step walkthrough of the execution process as well as an overview of the deliverables produced by the project.

04

Execution

Execution can be tailored to the clients’ needs and can come in time-boxed or milestone-based forms. Deliverables can either be set at project conclusion or can be set as milestones throughout the execution phase.

05

Conclusion

Upon completion of execution, QA will take place as per the four eyes principle and deliverables will be handed over to the client. Assessment reports will have prioritized, reproducible findings and associated remediation advice. Technical deliverables will come with documentation and instructive examples.
