DeepSec2021 Talk: On Breaking Virtual Shareholder Meetings: How Secure is Corporate Germany? – Andreas Mayer

Sanna/ October 29, 2021/ Conference

The Covid-19 pandemic has had a major impact on annual general meetings (AGMs) of shareholders worldwide. Due to existing gathering restrictions the vast majority of AGMs shifted from physical to online voting events. Therefore, purely virtual AGMs emerged to the new normal where shareholders approve critical company decisions. But how secure are those virtual events really? In this talk, I will present a systematic large-scale study on the security of 623 virtual AGMs held by German companies in 2020 including corporations listed in stock indices such as DAX and MDAX. In 72% of all virtual AGMs analyzed, at least one of the three CIA triad security goals was compromised. Join my talk and I will take you on an enthralling journey through the nitty gritty details and pitfalls that lead to the severe vulnerabilities

DeepSec 2021 Talk: Large-scale Security Analysis Of IoT Firmware – Daniel Nussko

Sanna/ October 15, 2021/ Conference

Today, the number of IoT devices in both the private and corporate sectors are steadily increasing. IoT devices like IP cameras, routers, printers, and IP phones have become ubiquitous in our modern homes and enterprises. To evaluate the security of these devices, a security analysis has to be performed for every single device. Since manual analysis of a device and reverse engineering of a firmware image is very time-consuming, this is not practicable for large-scale analysis. To be able to conduct a large-scale study on the security of embedded network devices, an approach was applied that allows a high number of firmware images to be statically analyzed. For data acquisition, a crawler was used to identify and retrieve publicly available firmware images from the Internet. In this way, more than 10,000 individual firmware images
