ATTACKS & VULNERABILITIES

TLDR InfoSec

UNCOVERING A 0-CLICK RCE IN THE SUPERNOTE NOMAD E-INK TABLET

There was a remote code execution vulnerability in the SuperNote A6 X2 Nomad tablet that let attackers on the same network compromise the device without user interaction. The exploit involved identifying an open port with a custom HTTP server, discovering a path traversal flaw for arbitrary file placement, and uploading a malicious firmware update to the EXPORT directory, which auto-installs using publicly available debug keys. The exploit was responsibly disclosed to Ratta Software in July - the company acknowledged it and made plans to fix it in its December 2024 update, but a patch has yet to appear.

TROX STEALER: A DEEP DIVE INTO A NEW MALWARE AS A SERVICE (MAAS) ATTACK CAMPAIGN

TROX Stealer, a Malware-as-a-Service first identified in December 2024, uses urgent debt collection phishing emails to entice victims into downloading malicious executables. It features a multi-stage execution chain with Python, Node.js, and WebAssembly to evade detection, stealing sensitive data like credit cards, browser credentials, cryptocurrency wallets, and Discord/Telegram session files. The attackers have a structured infrastructure, with domains registered nine months prior to the attack, indicating careful planning and marketing on hacking forums.

STATIC ANALYSIS VIA LIFTED PHP (ZEND) BYTECODE

Eptalights Research analyzes PHP code at the bytecode level, providing a reliable method for understanding execution. Its technology converts Zend bytecode into a Pythonic model, simplifying the analysis of obfuscated PHP code that is hard to interpret at the source level. This is especially useful for obfuscated code with goto statements or encoded files using loaders, granting access to control flow, variables, and call sites even when the source is obscured.
