Every Consultancy Is a Honey Pot Now

The Big Three consulting firms don't just advise on AI. They have become, in under two years, the fastest-growing storehouses of client intellectual capital on earth. McKinsey's Lilli held 46.5 million chat messages. 728,000 files. 57,000 accounts. All 95 system prompts, exposed. BCG's data warehouse fell next. Then Bain's Pyxis — eighteen minutes, start to finish, to a credential sitting in a public JavaScript file. Stop and think about what's inside those platforms. A consulting firm's AI is not a product. It is the compressed memory of every engagement the firm has ever run. Market entry plans. Pricing models. Restructuring scenarios. Board decks two quarters before they're presented. M&A target lists. Post-merger integration playbooks. The raw, unredacted conversations between a partner and a Fortune 500 executive about the thing that executive would never put in writing anywhere else. That is the product the Big Three sell. The chatbot is just the wrapper. The attacker understood this before the defenders did. An autonomous AI pen-test agent — not a nation-state, not a ransomware crew, one person with a clever tool — chose its three targets by reading the firms' own responsible-disclosure policies. It picked the vaults with the thinnest walls and the richest contents. Then it walked in through the front door each firm had left standing open in public JavaScript. The consulting industry built something the cybercrime world has been trying to build for twenty years: a single queryable interface to the private decisions of the Fortune 500. And they wrapped it in a chat box, gave it to junior consultants, and left the keys in the lobby. Every security lesson of the last decade — credential hygiene, defense in depth, least privilege, don't expose internal APIs — was apparently optional if the thing you were protecting was labeled "AI platform." Three breaches in six weeks is not a coincidence. It is a category. And the category is *elite-intellectual-capital honey pot*. The fix is not better prompt filtering. The fix is that any firm whose business model is "we know things your competitors don't" now runs one of the highest-value data stores on the internet — and needs to be secured like one. Not like an internal tool. Not like a productivity app. Like a crown-jewel system, with the adversary modeling, segmentation, and monitoring that goes with it. The advisors are now the case study.
