SaaS Supply Chain Attacks – Salesloft & Drift Breach Hits Palo Alto Networks, Zscaler, and Cloudflare

Executive Summary

massive SaaS supply chain attack is unfolding, targeting some of the world’s biggest corporations. Attackers exploited vulnerabilities in third-party SaaS platforms like Salesloft and Drift, stealing OAuth tokens that granted deep access into Salesforce integrations.

CyberDudeBivash confirms:

  • Victims include Palo Alto Networks, Zscaler, Cloudflare, and hundreds of other firms.
  • Stolen data includes business contacts, support cases, job titles, phone numbers, and metadata.
  • The attack demonstrates the immense risk of SaaS interconnectivity, where a single weak vendor can compromise giants.

 Background

What are SaaS Supply Chain Attacks?

  • Attacks where hackers exploit trusted third-party SaaS integrations to move laterally into enterprise environments.
  • Unlike traditional breaches, no direct compromise of the target’s infrastructure is required.

Why Salesloft & Drift?

  • Both platforms connect tightly to Salesforce CRM.
  • Attackers stole OAuth refresh tokens from Drift integrations, allowing stealth access.
  • The campaign ran from Aug 8–18, 2025, with integrations disabled on Aug 20.

 Technical Breakdown

Attack Chain

  1. Initial Access
    • Exploited Drift–Salesforce integration.
    • Compromised OAuth tokens → long-lived access.
  2. Execution
    • Attackers issued structured SOQL queries.
    • Exfiltrated CRM data without tripping alarms.
  3. Persistence
    • Used refresh tokens to maintain sessions.
    • No need for credentials or MFA bypass.
  4. Data Exfiltration
    • Exfiltrated customer contact lists, support cases, metadata, and possibly secrets.

 Impact Analysis

Companies Impacted

  • Zscaler – Customer contact info, case metadata, licensing info.
  • Palo Alto Networks – Salesforce case notes and CRM records.
  • Cloudflare – API tokens, support data, business contact info.

Data Stolen

  • Names, emails, phone numbers, job titles.
  • Support case metadata (but not attachments).
  • Licensing information.
  • Possibly AWS, Snowflake tokens in some environments.

Detection DifficultyHighLooks like legitimate API calls
Response ComplexityHighRequires token rotation & audits

 Mitigation Strategies

 Short-Term

  • Revoke & rotate all OAuth tokens tied to Salesloft/Drift.
  • Disable unused integrations.
  • Audit Salesforce logs for unusual queries.

 Long-Term

  • Enforce OAuth least privilege → minimize data accessible.
  • Ban storing secrets in Salesforce/support cases.
  • Implement Zero Trust API gateways to inspect third-party traffic.
  • Continuous SaaS vendor risk assessments.

 CyberDudeBivash Recommendations

  1. Third-party integrations are weakest links → audit them quarterly.
  2. Deploy API anomaly detection to flag strange SOQL queries.
  3. Establish SaaS incident response playbooks.
  4. Educate staff → never paste API keys or sensitive data in CRM cases.

 Conclusion

The Salesloft–Drift breach shows that OAuth tokens are the new crown jewels. Attackers don’t need your passwords if they can steal API tokens from a third party.

CyberDudeBivash urges:

  1. Treat SaaS vendors as part of your attack surface.
  2. Rotate & expire OAuth tokens aggressively.
  3. Build Zero Trust into SaaS ecosystems.
