News brief: Salesloft Drift breach update and timeline
Check out the latest security news from the Informa TechTarget team.
Additional information has surfaced and new victims have come forward in the Salesloft Drift breach, which has affected more than 700 organizations globally.
Salesloft and Salesforce announced on August 20 that they had revoked connections between Drift, an AI chatbot for sales and marketing teams, and the Salesforce CRM after detecting a security issue in the Drift application. On August 26, the companies announced that a threat actor used compromised credentials linked to the chatbot to gain unauthorized access to Salesforce instances between August 8 and 18, though new information has revealed the threat actor gained access to Salesloft's GitHub repositories months prior.
Read a timeline of the attack and its fallout below.
The breach highlights the importance of third-party risk management, fourth-party risk management and supply chain security, especially in SaaS environments, as well as strong authentication, including token security, privileged access controls and strong incident response procedures.
Google warns of credential theft campaign targeting Salesforce users
Google's Threat Intelligence Group reported that threat actor UNC6395 was targeting organizations using compromised OAuth tokens associated with Salesloft Drift.
Attackers used a Python tool to automate data theft from Salesforce instances between August 8 and 18, searching for sensitive credentials, including AWS access keys and Snowflake tokens.
Salesloft and Salesforce revoked the compromised tokens, and Salesforce removed Drift from its AppExchange marketplace. Google later warned that the compromise extended beyond Salesforce integrations, potentially affecting all authentication tokens connected to the Drift platform, including "Drift Email" integration tokens.

Severity of supply chain attack unclear
The Salesloft Drift attacks continue to expand as numerous cybersecurity companies report compromises, with Tenable joining the list of vendors.
Okta reported that it successfully prevented compromise through IP restrictions and security frameworks, including IPSIE.

GitHub compromise revealed as source
Mandiant's investigation revealed that threat actor UNC6395's attack on hundreds of Salesforce instances began with a compromise of Salesloft's GitHub account as early as March 2025.

Additional Salesloft Drift breach victims include Qualys, Rubrik, Spycloud, BeyondTrust, CyberArk, Elastic, Dynatrace, Cato Networks and BugCrowd.
