| | | [AI summary] The article provides an in-depth analysis of the firmware of a laptop's Realtek WiFi chip (rtl8821ae), exploring its architecture, communication protocols, and the RealWoW technology used for wake-on-wifi. It also discusses the possibility of creating a keylogger by leveraging the EC (Embedded Controller) and WiFi firmware interactions. The content includes insights into the 8051-based firmware structure, memory-mapped communication, and reverse engineering efforts to understand and modify the firmware. | ||
