Stand Alone Flask Application Template By K0NxT3D

The Stand Alone Flask Application Template is a minimal yet powerful starting point for creating Flask-based web UI applications. Developed by K0NxT3D, this template is designed to run a Flask app that can be deployed easily on a local machine. It features an embedded HTML template with Bootstrap CSS for responsive design, the Oswald font for style, and a simple yet effective shutdown mechanism. Here’s a detailed look at how it works and how you can use it.

Stand Alone Flask Application – Key Features

1. Basic Flask Setup
   The template leverages Flask, a lightweight Python web framework, to build a minimal web application. The app is configured to run on port 26001, with versioning details and a friendly app name displayed in the user interface.
2. Embedded HTML Template
   The HTML template is embedded directly within the Flask application code using render_template_string(). This ensures that the application is fully self-contained and does not require external HTML files.
3. Bootstrap Integration
   The application uses Bootstrap 5 for responsive UI components, ensuring that the application adapts to different screen sizes. Key elements like buttons, form controls, and navigation are styled with Bootstrap’s predefined classes.
4. Oswald Font
   The Oswald font is embedded via Google Fonts, giving the application a modern, clean look. This font is applied globally to the body and header elements.
5. Shutdown Logic
   One of the standout features is the built-in shutdown mechanism, allowing the Flask server to be stopped safely. The /exit route is specifically designed to gracefully shut down the server, with a redirect and a JavaScript timeout to ensure the application closes cleanly.
6. Automatic Browser Launch
   When the application is started, the script automatically opens the default web browser to the local Flask URL. This is done by the open_browser() function, which runs in a separate thread to avoid blocking the main Flask server.

How The Stand Alone Flask Application Works

1. Application Setup

The core setup includes the following elements:

This sets the title, version, and application name, which are used throughout the app’s user interface. The PORT is set to 26001 and can be adjusted as necessary.

2. Main Route (/)

The main route (/) renders the HTML page, displaying the app title, version, and a button to exit the application:

This route serves the home page with an HTML template that includes Bootstrap styling and the Oswald font.

3. Shutdown Route (/exit)

The /exit route allows the server to shut down gracefully. It checks that the request is coming from localhost (to avoid unauthorized shutdowns) and uses JavaScript to redirect to an exit page, which informs the user that the application has been terminated.

This section includes a timer that schedules the server’s termination after 1 second, allowing the browser to process the redirect.

4. HTML Template

The embedded HTML template includes:

• Responsive Design: Using Bootstrap, the layout adapts to different devices.
• App Title and Version: Dynamically displayed in the header.
• Exit Button: Allows users to gracefully shut down the application.

This structure creates a clean, visually appealing user interface, with all styling contained within the app itself.

5. Automatic Browser Launch

The following function ensures that the web browser opens automatically when the Flask app is launched:

This function is executed in a separate thread to avoid blocking the Flask server from starting.

How to Use the Template

1. Install Dependencies:
   Ensure that your requirements.txt includes the following:
   Flask==2.0.3


   Install the dependencies with pip install -r requirements.txt.

2. Run the Application:
   Start the Flask application by running the script:
   python app.py


   This will launch the server, open the browser to the local URL (http://127.0.0.1:26001), and serve the application.

3. Exit the Application:
   You can shut down the application by clicking the “Exit Application” button, which triggers the shutdown route (/exit).

Why Use This Template?

This template is ideal for developers looking for a simple and straightforward Flask application to use as a base for a web UI. It’s particularly useful for local or single-user applications where quick setup and ease of use are essential. The built-in shutdown functionality and automatic browser launch make it even more convenient for developers and testers.

Additionally, the use of Bootstrap ensures that the UI will look good across all devices without requiring complex CSS work, making it a great starting point for any project that needs a web interface.

The Stand Alone Flask Application Template by K0NxT3D is an efficient and versatile starting point for building simple Flask applications. Its integrated features, including automatic browser launching, shutdown capabilities, and embedded Bootstrap UI, make it a powerful tool for developers looking to create standalone web applications with minimal setup.

Web Scraping Basics:
Understanding the World of Scrapers

Web scraping basics refer to the fundamental techniques and tools used to extract data from websites. This powerful process enables users to gather large amounts of data automatically from the internet, transforming unstructured content into structured formats for analysis, research, or use in various applications.

At its core, web scraping involves sending an HTTP request to a website, downloading the page, and then parsing the HTML to extract useful information. The extracted data can range from text and images to links and tables. Popular programming languages like Python, along with libraries like BeautifulSoup, Scrapy, and Selenium, are often used to build scrapers that automate this process.

The importance of web scraping basics lies in its ability to collect data from numerous sources efficiently. Businesses, data scientists, marketers, and researchers rely on scraping to gather competitive intelligence, track market trends, scrape product details, and monitor changes across websites.

However, web scraping is not without its challenges. Websites often use anti-scraping technologies like CAPTCHAs, rate-limiting, or IP blocking to prevent unauthorized scraping. To overcome these hurdles, scrapers employ techniques like rotating IPs, using proxies, and simulating human-like browsing behavior to avoid detection.

Understanding the ethical and legal implications of web scraping is equally important. Many websites have terms of service that prohibit scraping, and violating these terms can lead to legal consequences. It’s crucial to always respect website policies and use scraping responsibly.

In conclusion, web scraping basics provide the foundation for harnessing the power of automated data extraction. By mastering the techniques and tools involved, you can unlock valuable insights from vast amounts of online data, all while navigating the challenges and ethical considerations in the world of scrapers.

SSH-Snake, a self-modifying worm that leverages SSH credentials.

Original Article : The Hacker News

A recently open-sourced network mapping tool called SSH-Snake has been repurposed by threat actors to conduct malicious activities.

“SSH-Snake is a self-modifying worm that leverages SSH credentials discovered on a compromised system to start spreading itself throughout the network,” Sysdig researcher Miguel Hernández said.

“The worm automatically searches through known credential locations and shell history files to determine its next move.”

SSH-Snake was first released on GitHub in early January 2024, and is described by its developer as a “powerful tool” to carry out automatic network traversal using SSH private keys discovered on systems.

In doing so, it creates a comprehensive map of a network and its dependencies, helping determine the extent to which a network can be compromised using SSH and SSH private keys starting from a particular host. It also supports resolution of domains which have multiple IPv4 addresses.

“It’s completely self-replicating and self-propagating – and completely fileless,” according to the project’s description. “In many ways, SSH-Snake is actually a worm: It replicates itself and spreads itself from one system to another as far as it can.”

Sysdig said the shell script not only facilitates lateral movement, but also provides additional stealth and flexibility than other typical SSH worms.

The cloud security company said it observed threat actors deploying SSH-Snake in real-world attacks to harvest credentials, the IP addresses of the targets, and the bash command history following the discovery of a command-and-control (C2) server hosting the data.

How Does It Work?

These attacks involve active exploitation of known security vulnerabilities in Apache ActiveMQ and Atlassian Confluence instances in order to gain initial access and deploy SSH-Snake.
“The usage of SSH keys is a recommended practice that SSH-Snake tries to take advantage of in order to spread,” Hernández said. “It is smarter and more reliable which will allow threat actors to reach farther into a network once they gain a foothold.”

When reached for comment, Joshua Rogers, the developer of SSH-Snake, told The Hacker News that the tool offers legitimate system owners a way to identify weaknesses in their infrastructure before attackers do, urging companies to use SSH-Snake to “discover the attack paths that exist – and fix them.”

“It seems to be commonly believed that cyber terrorism ‘just happens’ all of a sudden to systems, which solely requires a reactive approach to security,” Rogers said. “Instead, in my experience, systems should be designed and maintained with comprehensive security measures.”

“If a cyber terrorist is able to run SSH-Snake on your infrastructure and access thousands of servers, focus should be put on the people that are in charge of the infrastructure, with a goal of revitalizing the infrastructure such that the compromise of a single host can’t be replicated across thousands of others.”

Rogers also called attention to the “negligent operations” by companies that design and implement insecure infrastructure, which can be easily taken over by a simple shell script.

“If systems were designed and maintained in a sane manner and system owners/companies actually cared about security, the fallout from such a script being executed would be minimized – as well as if the actions taken by SSH-Snake were manually performed by an attacker,” Rogers added.

“Instead of reading privacy policies and performing data entry, security teams of companies worried about this type of script taking over their entire infrastructure should be performing total re-architecture of their systems by trained security specialists – not those that created the architecture in the first place.”

The disclosure comes as Aqua uncovered a new botnet campaign named Lucifer that exploits misconfigurations and existing flaws in Apache Hadoop and Apache Druid to corral them into a network for mining cryptocurrency and staging distributed denial-of-service (DDoS) attacks.

The hybrid cryptojacking malware was first documented by Palo Alto Networks Unit 42 in June 2020, calling attention to its ability to exploit known security flaws to compromise Windows endpoints.
As many as 3,000 distinct attacks aimed at the Apache big data stack have been detected over the past month, the cloud security firm said. This also comprises those that single out susceptible Apache Flink instances to deploy miners and rootkits.

“The attacker implements the attack by exploiting existing misconfigurations and vulnerabilities in those services,” security researcher Nitzan Yaakov said.

“Apache open-source solutions are widely used by many users and contributors. Attackers may view this extensive use as an opportunity to have inexhaustible resources for implementing their attacks on them.”
