AT&T

Revenue: $125.6 billion Initial access was via a CX contractor doing business with AT&T. Access originally used as vehicle for Equipment Changes/Call Forwarding (thanks a lot TORCH patch) - VPN + HVD (both external and internal MyDesktop) instances were accessed for a prolonged period without any detection or incident response taking place. Certificates exported from certlm in the VDI + OPUS self installer (automatically joins EP to S1) opened up the door to the VPN. Salesforce data was accessed via a project manager ATTUID + a DirecTV contractor who for some reason had the apps available in Salesforce.
