Visa Ships Security AI Harness That Edits Code Before Human Review
Visa is rolling out a security AI vulnerability agentic harness that runs an 11-stage scan by default and edits source files in the target repo unless operators cap it at detection. The release follows a Tenet Security demonstration of GhostJacking at DEF CON 34 and extends the pipeline, tightens Visa’s MTTA definition, and adds elapsed-time tracking from AI-flagged exploitability to validated production fixes.
