The gist: Klue Battlecards is the third compromised Salesforce-integrated app through which customer data has been stolen; victims include cybersecurity firm Huntress.
The collaboration app Klue Battlecards was compromised and misused for exfiltration of Salesforce data. This is already the third application in the Salesforce ecosystem through which such thefts have occurred.
Klue Battlecards, an application integrated into Salesforce for creating and managing competitive intelligence, was compromised and used for data exfiltration. Through the manipulated app, attackers were able to access Salesforce instances of customers and extract data. Cybersecurity firm Huntress confirmed being affected as one of the known victims.
This is the third integrated Salesforce application through which customer data thefts have occurred in recent times. The pattern demonstrates systematic exploitation of trusted apps in the Salesforce ecosystem to steal or misuse login credentials or access tokens.
For CISOs, this represents an increased risk in managing app permissions in cloud SaaS platforms such as Salesforce. What is needed is continuous monitoring of access by integrated apps, regular audits of permissions, and restriction of access based on the principle of least privilege. Incident response plans should include scenarios in which third-party apps abuse the trust placed in their integration.
