Fast Facts
- Google Threat Intelligence Group warns of a widespread data theft campaign by UNC6395, compromising over 700 organizations through a 10-day attack targeting Salesforce customers.
- Attackers used stolen OAuth tokens from Salesloft Drift to automate large-scale data exfiltration, mainly seeking credentials for AWS, Snowflake, and VPNs.
- The breach was contained after Salesloft and Salesforce revoked access on August 20, with impacted customers advised to search for and remediate compromised data.
- The attack demonstrated a high level of operational discipline and scale, exploiting OAuth token vulnerabilities and cloud integrations, with suspect origins still unknown.
Underlying Problem
A threat group called UNC6395 conducted a widespread data theft campaign over ten days in August, targeting hundreds of Salesforce customers who used the Salesloft Drift integration. The attackers exploited stolen OAuth tokens from Salesloft to access and exfiltrate sensitive data, including credentials for AWS, Snowflake, and VPNs, by automating the process with a Python tool and systematically searching for valuable secrets across compromised systems. This attack leveraged the interconnected nature of cloud services and third-party apps, highlighting a critical security blind spot in most organizations’ use of OAuth tokens and cloud-to-cloud integrations. The campaign’s extensive scope and disciplined methodology—covering over 700 organizations—surprised cybersecurity experts, who noted that the attackers appeared to operate with high professionalism in their query, extraction, and cover-up efforts.
The incident was first revealed after Salesloft notified affected customers and collaborated with Salesforce to revoke compromised tokens, halting the attacks by August 20. Salesforce clarified that only a small number of customers were impacted, emphasizing that the breach stemmed from a compromise of the app’s connection rather than any vulnerability in Salesforce itself. Google Threat Intelligence Group, reporting the incident, stated that the attackers’ motives remain unclear, and their precise origin is still unknown. They advised affected organizations to investigate their Salesforce instances, revoke API keys, rotate credentials, and remain vigilant for signs of data compromise. The overall tone suggests a highly organized and opportunistic attack targeting cloud service integrations, aimed at stealing sensitive credentials and possibly accessing further systems.
Critical Concerns
A recent high-profile cyber threat involves a widespread data theft campaign orchestrated by the threat group UNC6395, which targeted hundreds of Salesforce customers over a ten-day period in August by exploiting stolen OAuth tokens from the third-party AI sales tool, Salesloft Drift. Using automated Python tools, the attackers systematically accessed and exfiltrated vast volumes of sensitive data, including credentials for AWS, Snowflake, and VPNs, by leveraging a single compromised token to gain access across interconnected cloud services. While Salesforce and Salesloft swiftly revoked the compromised tokens, the attack exposed significant vulnerabilities in cloud-to-cloud integrations and OAuth token security, highlighting the persistent risks they pose to enterprise data integrity. This campaign’s highly disciplined and structured approach underscores how sophisticated threat actors are methodically exploiting misconfigured or weakly protected third-party app integrations, emphasizing the pressing need for organizations to implement rigorous credential management, continuous monitoring, and layered security controls to mitigate similar operational and data exfiltration risks in the future.
Possible Actions
Timely remediation is crucial in addressing the widespread impact of the recent attack spree linked to a third-party AI agent on hundreds of Salesforce customers. Swift action can minimize damage, restore trust, and prevent further exploitation, ensuring business continuity and safeguarding sensitive information.
