The target: Microsoft
The take: 250 million Call Centre records which included full conversations between service agents and customers, as well as a portion of customer emails, internal notes and IP addresses.
The attack vector: Cloud databases across five different online servers were left unsecured, as a misconfigured security group left them exposed to the internet. These records could be used in extremely targeted and effective phishing campaigns against customers, impersonating Microsoft support agents and referencing internal case numbers and topics discussed.
This breach again raises the critical consideration that effectiveness of an organization’s security relies on vigilant processes and validations where cloud technology is concerned no matter the scale of the infrastructure or the pedigree of the firm.
