The Five Doors Checklist
The five open doors in AI-built tools (keys, public links, broad roles, real data in test apps, no owner), each with a check a marketer can do without a developer.
On October 15, 2026, India's national cyber agency, CERT-In, said AI agents had reached the live systems of Indian organizations and read their business records. None of those organizations noticed. The AI companies that ran the tests reported it.
How they got in is the part that matters. They didn't break anything. They used credentials and connection settings that had been left lying around. CERT-In calls the root weaknesses conventional: keys left in code, test systems left open, permissions that were far too wide. What changed is speed: the agents found those gaps faster and at a larger scale than human attackers did, according to the advisory.
What changed on your side is who builds. A marketer with an AI builder can ship a working tool before lunch, and nobody asks a developer, because nobody thinks of it as software. CERT-In doesn't say those systems were built with AI. Its list is simply the plainest map of the doors.
Door 1. Keys in the code
A key is a password that lets one program talk to another: your ad account, your email platform, your customer database, an AI model. The quickest way to make an AI builder connect is to paste the key into the code, a settings file or the chat. A key that leaks once keeps working until somebody cancels it.
Door 2. A link anyone can open
On May 7, 2026, WIRED reported research by RedAccess: more than 5,000 apps built with tools like Lovable, Replit, Base44 and Netlify had essentially no login, and close to 2,000 appeared to show private data to anyone with the address. The researchers found them with ordinary Google and Bing searches.
Every tool you connect gets a set of permissions: read your ad account, or run it; see your contacts, or delete them. The easiest way to make a demo work is to give it everything, and CERT-In names over-permissive cloud and backend roles as one of the routes in.
Door 4. A test app holding a real customer export is the least protected thing you own, with the most real data in it. CERT-In gave the AI companies the same advice: synthetic data, fake credentials, production data kept out of tests. So test with ten invented rows. If a test app has ever held a real export, treat it as a real system: a login, an owner, and a date when it gets deleted.
Door 5. A tool nobody owns is a tool nobody rotates keys on, nobody reviews and nobody turns off. CERT-In asks for a complete inventory of connections, with the dormant ones switched off. The check is a spreadsheet:
[NAME] | [WHAT IT DOES] | [PERSON] | [ACCOUNTS / APPS] | [CUSTOMER, AD, FINANCE DATA] | [PERSON] | [DATE]
If the person who built it leaves, the row gets a new name.
Here's the order. Cancel the key. Make the link private. Then tell whoever owns the data, and your IT or legal contact, before you quietly fix anything else. Whether you have to notify anyone depends on the data and on where your customers live.
Finish the job. CERT-In says victims who only partly fixed the weaknesses were attacked again within days, on a larger scale.
