CYFIRMA Research: The Trust Cascade

A stolen credential at one company just breached a completely different company.
 
No malware in that second half. No phishing email either. Just an OAuth grant nobody flagged as risky.

CYFIRMA's new report, "The Trust Cascade," walks through four real, documented intrusions from the past year and finds they aren't isolated incidents. They're the same attack surface, entered from different points.
 
* An infostealer hits one employee's laptop. A completely unrelated company's OAuth connection to that same AI tool becomes the way in.
* One AI sales-agent vendor gets compromised. Its stolen tokens grant MFA-bypassing access into 700+ downstream organizations' Salesforce environments. (Salesloft / Drift)
* Coordinated AI sub-agents run a dozen reconnaissance waves against government systems in days, not months. (Taiwan)
* A single crafted email hijacks an AI assistant's reasoning and exfiltrates data without a single credential being touched. (EchoLeak)
 
Four different entry points. One outcome: identity, SaaS integrations, and AI agents behaving as a single connected attack surface, not four separate ones.
  
As agentic AI adoption accelerates, the question isn't whether identity, SaaS platforms, and AI agents will keep converging into one exploitable surface. They already have. The question is whether security ownership is converging just as fast.
