Contributed to the splunk/security_content repository by delivering two targeted detection features and a key bug fix over three months, focusing on clarity and reliability in security analytics. Enhanced horizontal port scan detection by optimizing SPL queries and refining YAML configuration, which improved detection speed and triage efficiency. Improved risk messaging for both Mshta and LOLBAS detections by including process context and standardizing message formats, supporting more accurate threat analysis and incident response. Collaborated closely with peers to ensure maintainable, well-documented solutions. Leveraged skills in Splunk, YAML, and data modeling to streamline detection logic, reduce false positives, and strengthen analyst workflows.

Jan 1, 2026January 2026 monthly summary for splunk/security_content. Delivered the Enhanced Risk Messaging for LOLBAS Detection feature, improving detection clarity and incident response by including the process_name in risk_message and enforcing consistent message formatting. This change enhances telemetry accuracy, supports faster triage, and reduces ambiguity in LOLBAS activity. The work includes version/date metadata bump and standardization of threat_object as the process, with co-authored contributions from Nasreddine Bencherchali and Bhavin Patel. Reference commit 9c9482bfb960962bba8528d417553f7ae0a2e642 and related notes in PR #3874.

Dec 1, 2025Month 2025-12: Delivered enhanced horizontal port scan detection improvements for splunk/security_content with a focus on performance and triage usability. The work refactors the query path to push more logic into tstats, adds new triage-friendly fields (including lastTime), and updates YAML configuration with versioning and metadata to clarify configuration. Also introduced an All_Traffic.rule to satisfy validation requirements and improve reliability during validation. No major bug fixes recorded this month for this repository. Overall impact: faster, more accurate detection of horizontal port scans, streamlined triage, and improved configuration reproducibility and validation readiness.
