One breach. 700+ companies compromised.

Trend Micro documented a cascading failure that began with the compromise of a single AI chatbot application and rippled outward to affect more than 700 organizations that relied on it. The AI app served as a shared service — companies integrated it into their workflows, granted it access to their data, and trusted it as infrastructure.

When the chatbot was compromised, the attacker didn't just get the chatbot's data. They got access to every company's data that flowed through it. Customer conversations. Support tickets. Internal processes. API credentials. The blast radius wasn't limited to one organization — it was every organization in the supply chain.

The incident demonstrated the domino effect of AI supply chain compromise: modern AI applications are interconnected, sharing data and access across organizational boundaries. A single point of failure becomes a single point of catastrophe that cascades through the entire ecosystem.

One AI app. 700+ victims. The interconnected AI supply chain isn't resilient — it's a chain of dominoes waiting for the first push.
