Abstract
The “Telecard” Israeli Payphones entered service in 1990, and at the height of their career there were 27,000 installed throughout the country. While most of them have already been removed from the streets, some remain in service in selected locations. Designed and manufactured at the late 80’s, they were nothing short of state-of-the-art embedded computer systems, capable of self-diagnosis and reporting. In this talk, we will explore one (or more) of those, from breaking into the chassis and all the way to code execution. Multiple challenges and multiple solutions make this a fascinating peek into an ahead-of-its-time device.
Description
In this talk I tell the story of how I decided to reverse engineer the Israeli payphone, which was nothing short of an engineering marvel for its time. The talk is laid out according to the MITRE ATT&CK tactics and shows how the same principles apply to fun projects and not just CNE.
