About security testing:
Tenendo specialists discovered an unattended staging environment and leveraged its vulnerabilities for sensitive information disclosure. This information was later reused in an attack against the main application, that allowed us access to the payment API on behalf of other customers of our Client.
During this social engineering engagement, it was possible to achieve persistent internal access, exfiltrate confidential and personal information, and compromise the internal segmented infrastructure.
The adversary simulation activity helped the client identify and remediate multiple issues with the on-premise infrastructure and vulnerabilities, calculate potential risks, and improve the overall security posture. Each finding also included proposed solutions for applying industry-standard defences.
