Summary

White House AI-security

The White House launched an AI-cybersecurity working group earlier this year to connect AI developers with critical-infrastructure operators for shared threat intelligence.

History

Historical Context

In September 2014 JPMorgan Chase disclosed a breach that exposed data from over 83 million accounts, prompting the Federal Reserve to order security overhauls and the bank to double its security budget. The incident became a benchmark for sector defenses; today FINRA’s Financial Intelligence Fusion Center uses that lesson as AI-vishing attacks on Two Sigma, Citadel and Point72 in 2026 threaten $1 billion in projected fraud losses.
