Labeling Experience

BUCKET INSPECTOR project (Jan 2025 – Mar 2025)

OtherDocumentData Collection

Created a multi-cloud scanning tool to detect publicly exposed storage buckets and misconfigurations. The output supports security data gathering that can be used for classification or risk labeling scenarios. The tool helps produce structured findings for later AI modeling or evaluation. • Scanned AWS, Azure, and Google Cloud for public buckets. • Identified misconfigurations and unauthorized access. • Collected findings suitable for downstream labeling. • Assisted in assessing exposure risk across environments.

SOC TOOLKIT project (Apr 2025 – May 2025)

OtherPrompt + Response Writing (SFT)

Built an investigation-support browser extension to streamline and organize cyber security analyst workflows. While not traditional dataset annotation, the tool assists in structuring investigation evidence that can be converted into labeled artifacts. This improves consistency and speed of producing analysis-ready outputs for AI or annotation pipelines. • Designed browser-based assistance for security analysts. • Streamlined investigation organization and note-taking. • Reduced time spent managing investigative context. • Enabled more consistent evidence capture for downstream use.

LLM KEY GUARD project (Apr 2025 – May 2025)

OtherData Collection

Developed an LLM key scanning and validation tool focused on detecting exposed AI API keys within a codebase. The work supports secure dataset creation by identifying sensitive tokens that could be included in training or testing samples. This enables safer downstream AI workflows and compliance during AI development. • Implemented detection logic to find exposed AI API keys. • Validated whether discovered keys are active and usable. • Applied the tool to a codebase context to prevent leakage. • Supported security hygiene for AI-related development outputs.
