Inside the 2025 Salesloft Supply Chain Breach: Token Theft at Scale
In August 2025, Salesloft, a leading AI chatbot provider, suffered a significant supply chain compromise when attackers exfiltrated authentication tokens via its Drift integration. The breach allowed unauthorized access to hundreds of customer-connected services, including Salesforce, Slack, Google Workspace, Amazon S3, Azure, and OpenAI, impacting more than 5,000 customers. The attackers, tracked as UNC6395 and possibly linked to ShinyHunters or Scattered Spider, began siphoning sensitive corporate data from at least August 8 to August 18, 2025. The incident led to mass data theft, urgent token invalidation efforts, and subsequent blocking of Drift integrations by Salesforce. This breach highlights the surging threats posed by identity-driven attacks and the risks of over-permissive third-party integrations in the enterprise cloud ecosystem. As attackers increasingly exploit centralized authentication and SSO environments, organizations face urgent pressure to revisit access controls and strengthen detection of abuse within legitimate user sessions.
