Opening Up the Samsung Q60 series smart TV

A technical analysis was conducted on the Samsung Q60 series smart TV, exploring its hardware, firmware, and network services through detailed reverse engineering techniques. The investigation involved board-level analysis, extracting and examining the eMMC flash memory, and investigating the proprietary VDFS filesystem. Multiple approaches were used to understand the TV's internal architecture, including examining debug ports, firmware upgrade processes, and network services.

Digital lockpicking - stealing keys to the kingdom

A security analysis of the KeyWe Smart Lock revealed critical vulnerabilities in its Bluetooth Low Energy communication protocol. The lock's in-house key exchange mechanism allows attackers to easily intercept and decrypt device communications by exploiting a predictable common key generation process. By analyzing the mobile application and BLE traffic, the vulnerability in the lock's cryptographic design was exposed.

AWS: Such auspices are very hard to read

awspx is a proof-of-concept tool designed to visualize and analyze complex AWS access management relationships. The tool helps identify potential attack paths by mapping out resource interactions and effective access within AWS cloud infrastructure. It addresses the challenge of understanding intricate AWS policy interactions by creating a graph-based representation of resource and action relationships.
