Additional Klue Supply-Chain Breach Victims Identified
Data exposed:
  • business contacts
  • support data
  • crm data

Hackers breached Klue in mid-June 2026 by using legacy credentials, gained access to OAuth tokens, and pulled business contact, support, and CRM data from connected Salesforce instances belonging to roughly two dozen customers.

Public reporting indicates the threat actor known as Icarus first compromised Klue’s systems and then exfiltrated information from the Salesforce environments of companies that had integrated with the competitor-intelligence platform. Among the newly disclosed victims are AlertMedia, Blackbaud, Camunda, and additional organizations that have begun notifying people whose records were taken. The attackers reportedly threatened to publish the stolen data. Available reporting describes the breach as a supply-chain incident in which one company’s compromise exposed contact and support details held by its customers.
