During September 2025, Salim Bitam enhanced security telemetry in the elastic/endpoint-package repository by introducing the thumbprint_sha256 field to endpoint data structures. This addition enabled explicit capture of code signature SHA256 hashes, supporting improved threat detection and forensic analysis. Salim focused on data modeling and schema definition, updating YAML schemas and Markdown documentation to ensure alignment with Elastic Common Schema standards. The work involved replicating ECS changes within the endpoint package, ensuring consistency across systems. Although no bugs were fixed during this period, the depth of schema and documentation updates demonstrated careful attention to data integrity and security-focused engineering practices.
