Widespread Cyberattack Targets Salesforce Instances, Compromising Sensitive Data

August 26, 2025

A important security breach has compromised the credentials of hundreds of Salesforce customers, according to recent findings by Google Threat Intelligence Group. The intrusion, which occurred primarily between August 8th and august 18th, has potentially impacted over 700 organizations and highlights the growing risks associated with third-party integrations.

How the Breach Unfolded

The attack centered around a vulnerability in the connection between Salesforce and Salesloft’s Drift AI chat agent. Threat actors, identified by Google as UNC6395, exploited compromised OAuth tokens to gain unauthorized access to numerous Salesforce instances. This allowed them to systematically harvest credentials, including sensitive access keys for Amazon Web services and Snowflake cloud platform tokens.

Researchers emphasize that the breach did not originate from a flaw within the Salesforce platform itself. rather, it leveraged a weakness in a connected application, demonstrating the importance of rigorously vetting and monitoring all third-party integrations.

Automated data Theft

the hackers employed a Python-based tool to automate the process of data theft, efficiently targeting each compromised association. While the attackers attempted to cover their tracks by deleting query jobs, this activity did not fully conceal their actions, enabling Google’s team to uncover the extent of the breach.

Response and Remediation Efforts

salesloft issued a security alert on August 20th, urging Drift administrators to promptly reauthenticate their Salesforce connections. Simultaneously, Salesforce began working to revoke active access and refresh Drift tokens. The company has temporarily removed Salesloft Drift from its AppExchange marketplace while conducting a thorough examination.

Salesforce,in a public statement,acknowledged the unusual activity and confirmed that its security teams were actively addressing the situation,providing support to affected customers.
