Threats Tagged 'salesforce'

Between mid-2025 and mid-2026, threat actors using tradecraft associated with ShinyHunters targeted customer SaaS applications, particularly Salesforce instances, through three primary intrusion paths. Voice phishing campaigns impersonated IT support to trick employees into authorizing malicious OAuth applications. Supply chain compromises leveraged trusted integrations including Salesloft, Gainsight, and Klue to obtain OAuth tokens for downstream customer access. Misconfigured guest access enabled exploitation of Aura framework functionality for unauthorized data queries. These techniques abused legitimate OAuth relationships to inherit user and application privileges, enabling enumeration and exfiltration of CRM data while evading authentication detections. The campaigns targeted multiple industries including retail, education, and manufacturing, highlighting risks in OAuth-connected applications and third-party integrations.

LastPass experienced a security incident through Klue, a third-party market intelligence platform integrated with its Salesforce and Gong systems. On June 12, 2026, LastPass was notified that an unauthorized actor exploited stolen OAuth tokens held by Klue to access customer relationship management data within LastPass's Salesforce environment. The exposed information includes customer names, email addresses, phone numbers, physical addresses, support case data, and sales records. Multiple Klue customers were affected by this supply chain attack. LastPass confirmed no Gong data was accessed, and customer vaults, master passwords, and encrypted vault data remain unaffected. The company has terminated Klue access, rotated compromised API tokens, and is cooperating with law enforcement while warning customers about potential phishing attempts using the exposed contact information.

On June 11, 2026, the Icarus threat group compromised Klue's backend systems, a market intelligence platform used by hundreds of enterprises to sync competitive battlecard data with CRM environments. The attackers exploited a dormant credential from an abandoned prototype integration to harvest OAuth tokens for Salesforce and Gong. Through automated API calls using Python scripts, the group exfiltrated CRM data including business contacts, price quotes, and sales communications from multiple customer Salesforce organizations. Klue detected the anomalous activity on June 12 and revoked OAuth credentials on June 13. The attackers subsequently launched an extortion campaign starting June 16, demanding victims contact them via Session Messenger within 48 hours.

In June 2026, a compromised Klue competitive-intelligence platform integration was exploited to exfiltrate customer relationship management data from enterprise Salesforce environments. Attackers authenticated through compromised Klue service accounts, generated OAuth tokens, and executed automated Python scripts to conduct bulk data extraction via Salesforce REST API queries over approximately 24 hours. The activity included concentrated bursts of nearly a thousand queries within 15 minutes and sustained extraction windows exceeding 6 hours. This incident follows similar third-party OAuth-abuse campaigns targeting Salesforce through Salesloft Drift and Gainsight integrations throughout 2025 and 2026. While the tactics resemble operations attributed to ShinyHunters and UNC6395 threat groups, attribution remains uncertain. The initial access vector, full scope of exfiltration, and attacker intent are still under investigation, with no extortion demands observed to date.

Two cyber criminal groups, UNC6040 and UNC6395, are targeting organizations' Salesforce platforms for data theft and extortion. UNC6040 uses social engineering, particularly voice phishing, to gain access to Salesforce accounts. They trick employees into granting access or sharing credentials, then use API queries or malicious connected apps to exfiltrate data. UNC6395 exploits compromised OAuth tokens for the Salesloft Drift application to access Salesforce instances. Both groups have been observed exfiltrating large volumes of customer data. Victims of UNC6040 have received extortion emails demanding cryptocurrency payments to prevent data publication. The FBI has provided numerous IP addresses and other indicators of compromise associated with these groups, along with recommended mitigations to enhance security and prevent such attacks.

In June 2025, Google's Salesforce instance was breached by UNC6040 & UNC6240 using vishing, OAuth app abuse, and anonymity layers. The attackers stole business data of small and medium-sized clients. A parallel attack by UNC6395 compromised Salesloft Drift's Salesforce integration, affecting hundreds of customers. Both incidents involved sophisticated social engineering, OAuth token abuse, and data exfiltration via TOR. The attacks are linked to the ShinyHunters group and share similarities with other high-profile breaches targeting various industries. The incidents highlight vulnerabilities in SaaS environments and the need for improved security measures, including OAuth governance, identity management, and proactive monitoring.
