Summary

In this technical episode of PolySécure, the host interviews Charles Meslay and Félix Aimé, two analysts from Sekoya’s Threat Detection and Research (TDR) team. They discuss the role of tooling in CTI, starting with a recent blog post about an APT28 campaign. Charles explains how they moved from manual reverse engineering using tools like dnSpy to an automated approach leveraging a custom MCP server and an orchestrator called Sara. Sara identifies file types, selects appropriate tools (e.g., Ghidra, IDA Pro), and produces structured reports, reducing analysis time from weeks to minutes. Félix then details the evolution of their internal tooling ecosystem, including a caching server for API quotas, 150 Maltego transforms, and custom applications like Tracker and Irma for infrastructure tracking and hunting. They emphasize the importance of ergonomics, making tools accessible via web interfaces to ensure adoption. The episode also covers their approach to open-sourcing tools, sharing concepts rather than code, and the transformative impact of AI on prototyping and knowledge capitalization. The discussion concludes with the ongoing consolidation of their ecosystem and the central role of human analysts in areas requiring expert judgment.

Critical Evaluation

Value of the Information & Strength of the Argument

The episode provides valuable insights into the practical application of tooling in a CTI team, offering concrete examples of how automation and AI can significantly enhance efficiency. The argumentation is solid, grounded in real-world experience, and the speakers articulate clear rationales for their tooling decisions, such as the trade-off between manual work and development time. They also highlight the importance of ergonomics and user adoption, which is a nuanced perspective often overlooked in technical discussions. The narrative is coherent and well-structured, moving from specific case studies to broader principles.

Scientific Rigor, Source Quality, Title Accuracy

The scientific rigor is high given the expert nature of the content. The speakers are experienced professionals, and their descriptions of tools and workflows are detailed and plausible. However, no external sources are cited, and the discussion relies solely on their internal experience. The title accurately reflects the content, focusing on the role of tooling in CTI. The episode does not include any promotional segments. No comments were provided for analysis.
