A analyze the TP-Link Tapo C200 camera firmware by dumping flash via UART and U-Boot, reversing AES-encrypted rootfs headers, and modifying the firmware to gain remote root access for deeper dynamic security analysis of the device.
Breaking Flash Encryption on Espressif ESP32: Side-Channel Attacks Against Embedded Security
Researchers demonstrated that flash encryption on Espressif ESP32 chips can be broken using side-channel power analysis. By measuring power traces during AES operations, attackers can recover encryption keys and potentially decrypt firmware stored in flash memory.
EDR-Redir V2: Blind EDR With Fake Program Files
A technique leveraging Windows bind link features to redirect and loop parent folders (like Program Files/ProgramData) so an EDR sees attacker-controlled files as its own, enabling stealthy evasion and potential DLL hijacks.
Defeating Windows DEP Using ROP Chains Leveraging VirtualAlloc
Uses manual Return-Oriented Programming (ROP) to chain existing code fragments and call VirtualAlloc, changing memory permissions to bypass Windows DEP and then execute shellcode in exploited process memory.
Total Recall – Retracing Your Steps Back to NT AUTHORITY\SYSTEM
A Windows elevation-of-privilege flaw in the Recall scheduled task let low-privileged users trigger it via WNF and abuse unsafe directory cleanup to execute arbitrary actions as NT AUTHORITY\SYSTEM.
