Applies toGeneral / Supply Chain

Why it mattersHighlights evolving platform security controls that attackers will need to bypass for CI/CD compromise.

Sources reviewed

19 items processed. Primary relevant findings centered on AI security trends (YesWeHack), detection templates (Project Discovery), and critical vulnerabilities (CISA KEV). General threat reports (Items 1-3) and tooling guides (Items 11, 14) were too broad/noisy for specific action.

Gaps identified

No external sources were found detailing the specific attack pattern of "malicious file uploads to AI project contexts" as described in the Anthropic report. Internal research should be developed to document this novel vector. [Internal: research/ai-platforms/anthropic-project-injection-report.md]
