The hidden battle inside the mainframe

You've probably never typed its name. But a machine built in the 1960s processed your last card swipe, your flight booking, your paycheck, and your insurance claim: the mainframe.

This month, researchers documented the first ransomware attack an AI carried out almost entirely on its own — no human steering the actual break-in. The systems it threatens most are the ones that are too critical to fail and too boring to watch.

If your company runs a mainframe — banks, insurers, airlines, government, big retail; if you're not sure, ask IT, the answer surprises people — BMC's Ken Chism has spent years mapping exactly what's usually missing: Zero Trust, real monitoring, a rehearsed recovery plan. BMC builds the software that closes those gaps, which is a commercial interest plainly stated, and also why he sees this battlefield more clearly than most.

If you don't run one, you still have a "mainframe." It's the aging server, the CRM nobody patches, the one machine finance depends on. The lesson from this month's AI attack applies at every company size: neglected systems just got cheap to attack — and, with the same AI used defensively, affordable to protect.

In the full edition: the three gaps that keep showing up, the insider threat that got an AI upgrade (deepfake job interviews are real, and rising 220% a year), the jargon translated into plain English, and four questions to ask about your most critical system — whatever it turns out to be.
