hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.

3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.

I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:

We provided a React template project for a Todo App. Your goal is to make the Todo App work by implementing the functionality for the components.

It should work the following way: The user can type anything in the input form, and press enter or click the "Add Item" button to add the item to the todo list. The todo list items should display in list format. You should then finally be able to mark items as "completed" or remove them from the list. When an item is marked as completed, have it display with a line through the text and be colored green.

When the app initially loads make sure the todo list is empty. You are free to add classes and styles, but make sure you leave the component ID's and clases provided as they are. Submit your code once it is complete and our system will validate your output.

import React from "react";

We are exploring our options for "Terms of use" and "Privacy policy" generation

Good known options

• Write it based on other sites and have a lawyer check it (estimate $100 to $200 for 1 hour)
• https://www.iubenda.com/en
  • $27/year for hosted international privacy policy (no terms of use without $990/year)
  • Sample: https://www.iubenda.com/privacy-policy/8032310
• https://termsfeed.com/
  • Nickle and dime pricing
• $72 estimated for privacy policy
