Sharing security insights and findings

This blogpage is maintained by the KPN REDteam. We are a group of ethical hackers working in the CISO office of KPN, making it our daily business to improve the security level of services and products that KPN delivers to customers.
In this small part of the internet we like to write about things we encountered in tests, experiences we had, and coordinated disclosures we did. These blogs are written by the persons involved and from a techical perspective. To make them accessible for a broad audience, they are written in English.
