Prompt Injection Surged 340% in 2026's OWASP Report

What did the report find?

OWASP’s 2026 security work put a number on something practitioners already felt: prompt injection is now the fastest-growing class of AI attack, up 340% year over year and present in roughly 73% of production deployments. The uncomfortable part is the prognosis. Several researchers argue injection is not a bug awaiting a patch but a structural property of systems that take instructions and data through the same channel — text in, behavior out.

The mechanics are simple. An attacker hides instructions inside content the model will read: a web page, an email signature, a shared document, a calendar invite. When the model processes that content, it cannot reliably separate “data to summarize” from “command to obey.”

Why the damage depends on autonomy

A poisoned instruction is only as dangerous as what the system will do with it. Read-only help on one pasted paragraph has a small blast radius. An agent with standing access to your inbox and files, plus the ability to send, buy, or delete, has a large one — there, an injected line becomes a real action taken in your name, with no one in the loop.

That is why 2026’s most exposed systems are the autonomous ones: always-on agents wired into accounts, acting between steps with no human checkpoint. The capability that makes them useful is the same capability injection exploits. Containment is increasingly the whole game — narrow what the agent can reach, and keep a person on the decision.

Where does ILURA stand?

ILURA’s exposure is bounded by design, not by a filter bolted on afterward. Three properties do the work. It is user-invoked — an agent runs when you call it, not on a loop scanning your accounts for something to do. It is human-reviewed — agents draft; you read the draft and decide to send it. And it works on selected text — only the words you hand it enter the workflow, on-device, through Apple Intelligence.

Put together, the classic injection path mostly closes. There is no autonomous agent with ambient account access for a hidden instruction to hijack, and no unattended step where a poisoned line turns into an irreversible action. If text you paste tried to smuggle a command, the worst case is a worse draft — which you see, and don’t send.

This is not a claim that ILURA is unhackable; no software earns that. It is a narrower, honest claim: the architecture the security field is converging on as the safer default — narrow reach, human in the loop, local by default — is the one ILURA already runs on.
