In August 2025, attackers exploited a compromise of Salesloft's GitHub account to steal OAuth tokens from the Drift chatbot integration, enabling access to Salesforce data of over 700 organizations. Major security vendors including Qualys, Tenable, Proofpoint, Black Duck, BeyondTrust, Cloudflare, and Palo Alto Networks were affected, with attackers exfiltrating support case data, business contacts, and internal notes. The breach was contained after Drift was taken offline, credentials were rotated, and integrations were restored following forensic investigation.
Jun 29, 2026In August 2025, attackers exploited OAuth tokens from Salesloft’s Drift integration, gaining access to hundreds of Salesforce and Google Workspace accounts. The campaign, attributed to UNC6395, bypassed traditional user-centric controls and enabled mass data exfiltration and credential harvesting, impacting a broad ecosystem of connected services. The incident highlights the urgent need for robust non-human identity governance, enhanced monitoring, and supply chain security practices.

Threat actors attributed as **UNC6395** used compromised OAuth tokens tied to the **Salesloft Drift** integration to access numerous customer **Salesforce** instances and systematically exfiltrate sensitive records, including **Account, Contact, Case, and Opportunity** data. The activity ran from at least **August 8 to August 18, 2025**, with investigators reporting that the attackers issued large volumes of Salesforce API requests, exported data in bulk, and in some cases deleted query jobs or queries to hinder detection. Google Threat Intelligence Group and Palo Alto Networks Unit 42 said the campaign was aimed not only at data theft but also at **credential harvesting**, with the stolen Salesforce data searched for secrets such as **AWS access keys, passwords, tokens, and Snowflake-related credentials** that could support follow-on compromise. Salesloft said it notified affected customers, while **Salesloft and Salesforce** revoked active Drift application access and refresh tokens on **August 20, 2025** and removed the Drift app from the Salesforce AppExchange during the investigation. Researchers emphasized that the incident did **not** stem from a flaw in the core Salesforce platform, but from abuse of third-party integration tokens in a broader SaaS supply-chain intrusion. Additional reporting said suspicious activity included logins from **`208.68.36[.]90`**, anomalous Salesforce API **GET**, **POST**, and **DELETE** requests, use of the user agent **`Python/3.11 aiohttp/3.12.15`**, and at least one case where a new user account was created for persistence; defenders were urged to review Salesforce, identity, and network logs and rotate any credentials exposed in the stolen data.
