Google Threat Intelligence Group (GTIG) is Google’s cyber threat intelligence organization. It tracks and analyzes malicious cyber activity, including identity-centric intrusions that abuse trusted cloud integrations and OAuth-based access. In the documented 2025 Drift-related intrusion activity, GTIG tracked a threat actor that used stolen OAuth tokens associated with the Salesloft Drift application to access Salesforce environments and a small number of Google Workspace mailboxes connected through Drift Email. The actor relied on valid bearer and refresh tokens rather than malware, enabling reconnaissance, bulk data access, exfiltration, and subsequent deletion of evidence through normal-looking API activity. Observed behavior included tenant and object enumeration, large-scale data collection via platform APIs, access to mailbox data through abused OAuth integrations, and defense evasion through removal of artifacts associated with bulk export jobs. GTIG’s reporting emphasized the security risks posed by agentic or non-human identities that are broadly trusted but insufficiently inventoried, monitored, and governed across SaaS platforms.
