## Connector risk landscape

AI assistant integrations with third-party services like Gmail and Slack combine access to private data, untrusted content, and external communication paths - creating a 'lethal trifecta' risk. PromptArmor research shows these connectors exist in a dynamic ecosystem that can upend security assumptions.

## Constantly evolving threat environment

In just six weeks from mid-May to end of June, 37% of existing connectors changed. 1,686 new tools were added while descriptions for 1,127 tools were rewritten. This rapid change renders security assessments obsolete quickly.

## Uncertainty in data flows

As seen in the Dropbox connector example, tool count increased from 8 to 24 during the study period. Write-capable tools grew from 3 to 10, while potentially destructive tools jumped from 0 to 4. Model instructions and permission scopes keep changing continuously.

## Unauthorized sharing of sensitive data

Research shows 40% of Claude connectors call additional AI services. For instance, Zoom's connector may send sensitive data to any of its 10 subprocessors. Users are typically unaware of these data flows.

## Geographical boundaries become irrelevant

Anthropic's documentation acknowledges connected services may process data on infrastructure outside the US. Enterprise plan 'US-only' settings don't affect third-party service locations.

## Expanding blast radius

Experts warn connectors exponentially increase attack impact by combining sensitive data with untrusted content. Even a single connector like email can lead to exfiltration of legal and financial communications.
