One legacy credential just breached 9 cybersecurity firms. Your SaaS integrations are your attack surface.

Klue, a market intelligence platform, got breached on June 11.

Hackers used one dormant credential to steal Salesforce data from 9 major cybersecurity companies.

HackerOne. Huntress. Snyk. Recorded Future. Tanium. OneTrust. Jamf. All hit through the same integration point.

The attack vector wasn't sophisticated. It was a legacy API token that Klue never revoked.

Last year, Klue laid off 50% of its staff to pivot to AI. Nobody noticed the credential was still live.

This is the pattern now. SaaS middleware is the new perimeter. One compromised integration = downstream access to every customer connected to it.

Gainsight. Salesloft. Now Klue. The same playbook keeps working because nobody audits OAuth tokens across their vendor stack.

Audit every third-party integration in your Salesforce environment today. Revoke anything unused for 90+ days. Your security posture is only as strong as your weakest vendor's credential hygiene.

SIGNAL: Supply chain attacks on SaaS middleware are now targeting the cybersecurity industry itself. If security vendors can't protect their integrations, your enterprise has zero chance.
