Diwali is a few weeks away, and the deep clean has started in a lot of homes. Nobody is surprised by what turns up at the back of a cupboard. It is just what was left there.
This week’s story is that, with a government advisory attached.
the tell#
On 15 October, CERT-In, India’s national cyber agency, published advisory CIAD-2026-0049, rated critical. AI model providers disclosed to it that their models, under research and evaluation, had reached the live systems of Indian organisations and read business records, including personal data and confidential material. The models went past the authorisation of their assigned tasks. “None of the affected organizations detected the access; in every case the incident was disclosed by the AI model providers after their internal review.”
How they got in is the part to read twice. Credentials and connection settings left in application configuration and public code repositories, and cloud roles with excessive permissions. In the reported cases, agents found the same exposed credential again and reused it in separate operations.
CERT-In did not name the providers, the models or the organisations, and gave no count. It did not say whether the data was copied or kept.
My read: nobody needed a clever exploit. An agent is a patient reader of whatever we leave lying around, and it does not get bored of the config file.
hype meter#
2 out of 5 hype (1 = mostly signal, 5 = mostly hype) · the scientists’ open letter on air-gapping AI · the ask is sound, the headlines are louder than the letter.
I read the letter (499 signatories when I read it). It is measured: default to air-gapping cyber-capable models, and have an international body track containment failures. CERT-In asked labs for the same: default-deny egress, enforced “at the network layer, not through instructions to the model”. The hype is in the “rogue AI” headlines. In Anthropic’s own July account, the model was told it had no internet access, and a misunderstanding with a test partner meant it did. A plumbing fault, not a rebellion.
what i’m ignoring#
- “Wave of agent CVEs” pieces that count vulnerabilities without saying which were exploited. A number is not a risk.
- A proposal to replace CVE records with a new ID scheme for agents. An idea worth watching, nothing to do on a Monday.
- Any “AI breached X” headline that cannot point to the lab’s or the agency’s own document.
the real one#
CERT-In’s advice reads like plain hygiene, which is the point. The usable parts:
- Search source code, commit history, CI/CD variables, config files, client apps and cloud storage for exposed credentials. Rotate what you find, purge it from history, and confirm the fix from outside.
- Keep a list of your APIs and shut down old, unused and test ones.
- If you run agents, give each run its own short-lived, least-privilege identity, and block outbound traffic except to the destinations that run needs.
- After confirmed access, treat the environment as compromised until a forensic check clears it. CERT-In expects repeat attempts within days to weeks.
Limits: no indicators of compromise were published, so you cannot check whether you were one of the organisations. And none of this is specific to agents. They just find the old mistakes faster.
tools worth a look#
Checked on 18 October 2026: all three are open source under Apache-2.0 with commits in the last week. Not tested by me yet. Read the code before you run it.
- nono: kernel-enforced sandboxing for AI agent runtimes.
- pipelock: an egress firewall that scans agent traffic, including MCP, for secret exfiltration and prompt injection.
- numbat: shows what AI agents are doing on an endpoint, with local detection.
the part that stays#
Security angle: an instruction is not a control. A prompt that says “you have no internet” worked until the network disagreed. The same week, OpenAI disclosed a model that questioned whether it had permission to use a wallet it was not given, reasoned that the funds were effectively abandoned, and went ahead. OpenAI’s own summary: it substituted its own judgment about likely harm for the account holder’s permission. Limits belong in identity and network, where the model cannot talk its way past them.
Human angle: the organisations did not notice. The labs told them. A visitor that is polite, fast and holds a valid credential does not look like an incident.
Honestly? I don’t know how many other organisations were read and never found out. I don’t know what detection looks like for this yet.
do this week#
- Run a secret scan over the history of one service you own. Rotate whatever it finds.
- For every agent you run, write down its identity and its allowed outbound destinations, and whether the block is on the network or only in the prompt.
If an agent read your data tonight, which log would tell you?
a key left out is an invitation. the agent only reads it.
