Stealing cars just has been made more accessible to the public!
Tags: cybersecurity, security, pentesting, ai
Published: 2024-02-15 09:06:52

You read right, after the release of the Quansheng Radio (similar radio to the Baofeng series), the process of car stealing just became easier and cheaper for the general public, eliminating the need for complex technology or deep knowledge on the topic.

**Disclaimer this is only for educational purposes and does not encourage cyber crimes or illegal activities!**


## 1. The cheap way and the problems with it


Recently, our team has been researching car key fob signals being blocked by everyday devices that use radio frequencies. 
We discovered that this role is best suited by the popular ham radios such as Baofeng. Since the Baofeng radio has a wide range of frequencies, it can be used to scan for the key fob signal. After finding the correct frequency, the radio becomes the best way to suppress the lock signal to the car, by transmitting on the key fob frequency, thus making the car unlocked and accessible to anyone around. But as you may have already thought, finding the signal through scanning is going to take some time and make the attack longer as well as not so certain to happen, because it can take multiple scanning attempts to find the frequency. Also, the timing is very important, if you miss the key fob signal you are going to need to start the scanning again. Those are quite some problems for a pentester to be dealing with on the field.

## 2. The cheap and easier way
On the other hand, we have the recently released Quansheng radio. It fixes all the problems and makes the life of a pentester easier, because of its spectrumscope feature. It analyzes the frequencies around the radio in real-time, thus making the frequency discovery of the key fob almost instantaneous and being able to launch the attack on the first try. All of that can be achieved only for 30 - 40 dollars. 
![Quansheng Radio Spectrum Mode](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fec2nkhyl7m3qnk7hn1l.png)
## 3. Is it really that easy to achieve a car steal?

Short answer yes, but there are some special environmental factors that we have to take into account. For example, the chance of someone locking his car and not looking back or checking if it is locked is not very common. Many people at least look back to see the blinking lights of the car indicating that the car is locked.
Another thing that is going to be a setback is the way newer cars start, many of them need some type of NFC identification from the key fob in order to start, hot-wiring is going to work only on older models, that do not have that good of a security.
Elevating Python Data Structures with `namedtuple`
Tags: python, namedtuple, programming
Published: 2024-02-15 08:52:38

Python's standard library is a treasure trove of tools designed to streamline your coding experience, making it more efficient, readable, and expressive. 

Among these tools, the `collections.namedtuple` stands out as a particularly elegant solution for when you need the simplicity of a tuple but with readable, self-documenting code. 

In this post, we delve into how `namedtuple` can transform your data handling, illustrated with a straightforward example of representing a point in a 2D space.

---

## What is `namedtuple`?
`namedtuple` is part of the collections module and provides a way to create tuple-like objects that are accessible via named attributes in addition to being indexable and iterable. 

This feature combines the immutability of tuples with the readability of dictionaries, making your code not only cleaner but also easier to maintain.

---

## Why Use `namedtuple`?
The appeal of `namedtuple` lies in its simplicity and the clarity it brings to your code. 

Traditional tuples are lightweight and fast, but accessing their elements requires indexing, which can make your code less readable, especially to someone unfamiliar with the structure of your tuples. 

`namedtuple` addresses this by allowing you to access elements by name.

---

## A Practical Example: Representing a Point
Consider the task of representing a point in a two-dimensional space. With a regular tuple, you might do something like this:

```
point = (1, -5)
print(f"The point is at ({point[0]}, {point[1]}).")
```

While this works, it's not immediately clear what point[0] and point[1] represent without additional context. 

Now, let's see how `namedtuple` enhances this:

### Using namedtuple

```
from collections import namedtuple

# Creating a namedtuple to represent a point
Point = namedtuple('Point', 'x y')
pt = Point(1, -5)

# Accessing the point's coordinates
print(f"The point is at ({pt.x}, {pt.y}).")
```

### Output

```
The point is at (1, -5).
```

This code snippet demonstrates how `namedtuple` makes the code more readable and self-documenting. 

The Point object clearly indicates that it has x and y attributes, making the print statement more understandable.

---

## Advantages of `namedtuple`
- Readability: Accessing elements by name makes your code more self-explanatory.
- Efficiency: `namedtuple`objects are as lightweight as regular tuples.
- Immutability: Like tuples, `namedtuple` objects are immutable, which can help prevent bugs related to accidental modification of objects.

---

## Conclusion
`namedtuple` is a powerful tool for those looking to combine the efficiency and immutability of tuples with the readability of dictionaries. 

By incorporating `namedtuple` into your Python projects, you can make your data structures more self-documenting, improving both the maintainability and readability of your code. 

Whether you're handling complex data models or simply need a more descriptive way to organize your data, `namedtuple` offers a Pythonic solution that is both elegant and practical

Difference between "npm i" and "npm ci"
Tags: package, npm, npmci, npmi
Published: 2024-02-15 08:23:20

**Basically**, **npm install** reads **package.json **to create a dependency list and uses package-lock.json to specify which dependency versions to install. If the dependency is not in the package-lock.json file, it will be added via npm install.

**npm ci** (also known as Clean Install) is designed to be used in an automated environment such as testbench, integration and continuous deployment, or any situation where you want clean development of dependencies. .

Loads dependencies directly from package-lock.json and uses only package.json to ensure there are no conflicts in dependencies. If a dependency is missing or the version is incompatible, an error is thrown.

Use npm install to add dependencies and update the project's dependencies. Most of the time you will use this during development after downloading the changes that update your progress, but using npm ci this way may be a good idea.

Again, use npm ci if you want a decision. For example, continuous integration, automatic operation, etc. in the process. And while it installs successfully the first time, npm install does not.


**npm install**
Install the package and all its dependencies.
Dependencies are driven by npm-shrinkwrap.json and package-lock.json (in that order).
Unlimited: Fix dependencies of native module.
International packages can be installed.
All missing dependencies will be placed in node_modules.
Can be written to package.json or package-lock.json file. When used with the
(npm i packagename) parameter, it can be written to the package.json file to add or update dependencies.
When used without arguments (npm i), some dependencies can be written to the package-lock.json file to lock their structure if they are not already in this file.< br> 

**npm ci**
Minimum Required npm v5 . 7.1.
package-lock.json or npm-shrinkwrap.json must be present.
Returns an error if the dependencies of the two files are not related to package.json.
Remove node_modules and install all dependencies now.
Never writes to package.json or package-lock.json.

Backend Development Plan
Tags: javascript, typescript, node, api
Published: 2024-02-15 08:00:00


If you are curious or new to programming maybe you'd like to give Nodejs a try.

I am planning on starting a new series on backend development with Nodejs, javascript and typescript. And these are the concepts I would cover. Not that detailed at the moment.

- Introduction to Backend
  - what is the backend
  - what is an API
  - what is rest API
  - what is JSON
  - request and response
- Nodejs
- JavaScript
  - what is Javascript
  - how to set up
  - resources
  - programming in Javascript
- Node Packages and Yarn/npm
- Typescript
- Express
- Joi
- JSON Web Tokens
- Database and SQL
- Deploy application on render

We would discuss generally backend (APIs) and then set up Nodejs and vscode. We will discuss validation then use Joi and then create a middleware for validation. We will create a simple project, usually a todo app project but we will include a user, who will implement authentication using JSON web tokens before we will use basic authentications. We will add a database. We will use SQLite if we can not use mysql or Postgresql. We will use MongoDB (mongoose). Finally, we will deploy this simple application and deploy it on render. 

PS: Let's see how far I can do this.
