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.

ABOUT

What is Fimmer?

Most feeds treat all company headlines the same. An executive interview, an office closure, stock analysis, and a data breach can sit side by side with no sense of scale. Fimmer ranks coverage by what matters, so important events stand out and signals are prioritised over noise. We cluster related company news and score each story using a range of metrics, so you see the most crucial stories first.

SCORING

What do the scores mean?

Significance (0–10) measures the scale of the real-world impact. Sentiment and ESG (−10 to +10) indicate the tone of the coverage and whether the change relates to environmental, social, or governance factors. Together, these scores help distinguish meaningful developments from routine company news. More information about our scoring methodology can be found on our About page.
