Overview

  • Reports say up to 2.5 billion Gmail users had business names and contact information taken from a Salesforce‑hosted Google CRM in June.
  • Google acknowledged the incident on August 5 and began notifying affected customers on August 8, stating the leaked data was basic contact information.
  • ShinyHunters is reported to have deceived a Google employee to obtain login credentials, enabling access to the CRM instance.
  • Criminals are leveraging the stolen contact lists for impersonation and phone scams, with users reporting calls from 650 area code numbers urging password resets.
