F5 zero-day hit before a patch existed as AI-agent security funding keeps flowing

A critical F5 zero-day already under attack before a patch existed anchors a week where AI-agent security funding kept flowing (Cyera, then Island, each landing nine-figure rounds), suspected North Korean hackers pulled off a $351.6 million exchange heist, and counter-drone hardware kept multiplying, from Army lasers at the border to Marine systems in the Middle East. If you read only one story, make it the F5 flaw: it sits inside access-control infrastructure most networks treat as trusted.
