Cloud Security / Threat Intelligence
A significant data breach has targeted the sales automation platform Salesloft, allowing hackers to steal OAuth and refresh tokens linked to the Drift AI chat agent. This opportunistic attack has been connected to a threat group identified by Google Threat Intelligence Group (GTIG) and Mandiant, known as UNC6395. GTIG has reported over 700 potentially affected organizations. According to researchers Austin Larsen, Matt Lin, Tyler McLellan, and Omar ElAhdan, the attacks began as early as August 8, 2025, and continued until at least August 18, 2025, focusing on Salesforce customer accounts through the compromised Salesloft Drift application. The hackers have been seen exporting large volumes of data from various corporate Salesforce instances, likely in an effort to harvest credentials for further exploitation.
