If I’m being honest, the most useful skill for hacking is learning to do research. And since Google’s search is going to shit, allow me to detail some of the methods I use to do OSINT and general research.

Google dorking is the use of advanced syntax to make incredibly fine-grained searches, potentially exposing information that wasn’t supposed to be on the internet:

Some of my go-to filters are as follows:

“Query” searches for documents that have at least one field containing the exact string.

site: allows for a specific site to be searched. See also inurl and intitle.

type: specifies the tor of resource to look for. Common examples are log files, PDFs, and the sitemap.xml file.

Metasearch engines (such as SearxNG) permit you to access results from several web-crawlers at once, including some for specialized databases. There are several public instances available, as well as some that work over tor, but you can also self-host your own.

IVRE is a self-hosted tool that allows you to create a database of host scans (when I say self-hosted, I mean that you can run this in a docker container on your laptop). This can be useful for finding things that search engines don’t show you, like how two servers are related, where a website lives, etc. I’ve used this tool before, in my investigation into the Canary Mission and its backers.

Spiderfoot is like IVRE, but for social networks. It is also a self-hosted database. I have also used this in the Canary Mission investigation.

Some miscellaneous websites/web tools I use:

SecurityTrails: look up DNS history for a domain

BugMeNot: shared logins for when creating an account is not in your best interest.

Shodan/Censys: you have to make an account for these, so I don’t usually recommend them.

OSINT framework: another useful index of tools for information gathering.

There are several key custom software development principles you need to know, practice, and live by. These principles are a popular list of philosophies, styles, practices, and approaches used by the top software engineering teams in the industry. As an experienced software developer, you know the importance of strict principles and processes to achieve clean codes.  Using the top programming principles, you can effectively develop software programs that meet all the needs and requirements of your clients. Of course, these guiding principles help to establish the foundation for product planning, development, and deployment. Moreover, they help to estimate time, forecast costs, boost transparency, and streamline accuracy. If you are interested in optimizing your pipeline today, read on to learn about the key custom software development principles to live by. Keep It Simple As you prepare to code your next custom software product, you need to ensure that your code is clean, maintainable, and readable. Make sure that each function of your program is incredibly small. Ideally, a single method should not exceed forty or fifty lines. In addition, make sure that each method only solves a single problem.  This way, functions can easily be modified or altered without difficulty. Of course, using this principle allow you to identify and fix even the scariest bugs quickly. Moreover, it assists you in making future changes and modifications to your source code. Keeping it simple is one of the most popular lean principles in custom software development. Remain, Patient,  Continuously remaining patient is key in software development. Software development teams are constantly worried about hitting deadlines at all costs. However, working through uncertainty, and challenging software solutions often requires patience. By being patient throughout software development, you can make more confident decisions, achieve better software, and improve your work environments and employee productivity. Of course, this can help you focus on long term goals, achieve better mental health, and reduce impulsive decision making. Containerize Containerizing has become one of the largest emerging custom software development principles to begin using this year. Containerization is a form of operating system virtualization where applications are stored in isolated user spaces that are referred to as containers. Once packaged inside containers, your custom software application can efficiently run across different operating systems and computing environments. Needless to say, this development principle improves portability, efficiency, and agility across your pipeline.  To improve your containerization performance, there is an abundance of reliable tools, resources, and systems to take advantage of. For example, you can use a container registry by JFrog as a single access point to manage and control all of your remote Docker images. To improve security, flexibility, and management across your SDLC and life, utilize the containerize programming principle. Don’t Repeat Yourself They don’t repeat yourself, or the DRY principle focuses on reducing code repletion and effort across custom software systems. Simply, this principle means you should never write the same code or configuration twice. Using this approach, you can promote reusability, maintainability, and extendibility across your software programs. To initiate the DRY approach, extract all common logic into sophisticated functions. At the same time, you should implement automated systems in order to keep your code lean. In custom software development, following the DRY, or don’t repeat yourself principle will help you streamline code reusability without being forced to repeat it. Measure Twice, Cut Once Measure twice, cut once is often regarded as the most important principle in all of custom software development. Simply, this means you should always double-check your measurements for accuracy before implementing a function.

Otherwise, it may be necessary to ‘cut’ a second time, wasting valuable time and resources. As a software developer, this encourages you to select the right problem to solve, determine the best approach, and choose the optimal resources to solve it. Using this method, development teams are encouraged to prepare extremely carefully and thoroughly before taking action. To gain new IT confidence and skills, always measure twice and cut once. There are several key custom software development principles, philosophies, styles, practices, and approaches to live by. Keeping it simple is one of the most popular lean principles in custom software development. In addition, by being patient throughout software development, you can make more confident decisions, improve your work environment, and achieve better software.  At the same time, containerizing has become one of the largest emerging custom software development principles to begin using this year. Moreover, following the DRY, or don’t repeat yourself principle will help you streamline code reusability without being forced to repeat it. Furthermore, Measure twice, cut once is often regarded as the most important principle in all of custom software development. Follow the philosophies highlighted above to learn about the key custom software development principles to live by.

What Makes a Great DevSecOps Developer: Insights for Hiring Managers

In the fast-pacing software industry security is no longer a mere afterthought. That’s where DevSecOps come in the picture - shifting security left and integrating it across the development lifecycle. With more tech companies adopting this approach, the demand for hiring DevSecOps developers is shooting high.

But what exactly counts for a great hire?

If you are a hiring manager considering developing secure, scalable, and reliable infrastructure, to understand what to look for in a DevSecOps hire is the key. In this article we will look at a few top skills and traits you need to prioritize.

Balancing Speed, Security, and Scalability in Modern Development Teams

Security mindset from day one

In addition to being a DevOps engineer with security expertise, a DevSecOps developer considers risk, compliance, and threat modelling from the outset. Employing DevSecOps developers requires someone who can:

Find weaknesses in the pipeline early on.

Include automatic security solutions such as Checkmarx, Aqua, or Snyk.

Write secure code in conjunction with developers.

Security is something they build for, not something they add on.

Strong background in DevOps and CI/CD

Skilled DevSecOps specialists are knowledgeable about the procedures and tools that facilitate constant delivery and integration. Seek for prior experience with platforms like GitHub Actions, Jenkins, or GitLab CI.

They should be able to set up pipelines that manage configurations, enforce policies, and do automated security scans in addition to running tests.

It's crucial that your candidate has experience managing pipelines in collaborative, cloud-based environments and is at ease working with remote teams if you're trying to hire remote developers.

Cloud and infrastructure knowledge

DevSecOps developers must comprehend cloud-native security regardless of whether their stack is in AWS, Azure, or GCP. This covers runtime monitoring, network policies, IAM roles, and containerization.

Terraform, Docker, and Kubernetes are essential container security tools. Inquire about prior expertise securely managing secrets and protecting infrastructure as code when hiring DevSecOps developers.

Communication and collaboration skills

In the past, security was a silo. It's everyone's responsibility in DevSecOps. This implies that your hiring must be able to interact effectively with security analysts, product teams, and software engineers.

The most qualified applicants will not only identify problems but also assist in resolving them, training team members, and streamlining procedures. Look for team players that share responsibilities and support a security culture when you hire software engineers to collaborate with DevSecOps experts.

Problem-solving and constant learning

As swiftly as security threats develop, so do the methods used to prevent them. Outstanding DevSecOps developers remain up to date on the newest approaches, threats, and compliance requirements. Additionally, they are proactive, considering ways to enhance systems before problems occur.

Top candidates stand out for their dedication to automation, documentation, and ongoing process development.

Closing Remarks

In addition to technical expertise, you need strategic thinkers who support security without sacrificing delivery if you want to hire DevSecOps developers who will truly add value to your team.

DevSecOps is becoming more than just a nice-to-have as more tech businesses move towards cloud-native designs; it is becoming an essential component of creating robust systems. Seek experts that can confidently balance speed, stability, and security, whether you need to build an internal team or engage remote engineers for flexibility.

- At least 4GB of RAM - At least 2 CPU cores - At least 25GB disk space - You can use docker or any Container runtime app. Ensure Docker Compose plugin is also installed. - Port 25 outbound should be open (A lot of cloud providers block it)

Postal Installation

Should be installed on its own server, meaning, no other items should be running on the server. A fresh server install is recommended. Broad overview of the installation procedure - Install Docker and the other needed apps - Configuration of postal and add DNS entries - Start Postal - Make your first user - Login to the web interface to create virtual mail servers Step by step install Postal Step 1 : Install docker and additional system utilities In this guide, I will use Debian 12 . Feel free to follow along with Ubuntu. The OS to be used does not matter, provided you can install docker or any docker alternative for running container images. Commands for installing Docker on Debian 12 (Read the comments to understand what each command does): #Uninstall any previously installed conflicting software . If you have none of them installed it's ok for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done #Add Docker's official GPG key: sudo apt-get update sudo apt-get install ca-certificates curl -y sudo install -m 0755 -d /etc/apt/keyrings sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc sudo chmod a+r /etc/apt/keyrings/docker.asc #Add the Docker repository to Apt sources: echo "deb https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null sudo apt-get update #Install the docker packages sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y #You can verify that the installation is successful by running the hello-world image sudo docker run hello-world Add the current user to the docker group so that you don't have to use sudo when not logged in as the root user. ##Add your current user to the docker group. sudo usermod -aG docker $USER #Reboot the server sudo reboot Finally test if you can run docker without sudo ##Test that you don't need sudo to run docker docker run hello-world Step 2 : Get the postal installation helper repository The Postal installation helper has all the docker compose files and the important bootstrapping tools needed for generating configuration files. Install various needed tools #Install additional system utlities apt install git vim htop curl jq -y Then clone the helper repository. sudo git clone https://github.com/postalserver/install /opt/postal/install sudo ln -s /opt/postal/install/bin/postal /usr/bin/postal Step 3 : Install MariaDB database Here is a sample MariaDB container from the postal docs. But you can use the docker compose file below it. docker run -d --name postal-mariadb -p 127.0.0.1:3306:3306 --restart always -e MARIADB_DATABASE=postal -e MARIADB_ROOT_PASSWORD=postal mariadb Here is a tested mariadb compose file to run a secure MariaDB 11.4 container. You can change the version to any image you prefer. vi docker-compose.yaml services: mariadb: image: mariadb:11.4 container_name: postal-mariadb restart: unless-stopped environment: MYSQL_ROOT_PASSWORD: ${DB_ROOT_PASSWORD} volumes: - mariadb_data:/var/lib/mysql network_mode: host # Set to use the host's network mode security_opt: - no-new-privileges:true read_only: true tmpfs: - /tmp - /run/mysqld healthcheck: test: interval: 30s timeout: 10s retries: 5 volumes: mariadb_data: You need to create an environment file with the Database password . To simplify things, postal will use the root user to access the Database.env file example is below. Place it in the same location as the compose file. DB_ROOT_PASSWORD=ExtremelyStrongPasswordHere Run docker compose up -d and ensure the database is healthy. Step 4 : Bootstrap the domain for your Postal web interface & Database configs First add DNS records for your postal domain. The most significant records at this stage are the A and/or AAAA records. This is the domain where you'll be accessing the postal UI and for simplicity will also act as the SMTP server. If using Cloudflare, turn off the Cloudflare proxy. sudo postal bootstrap postal.yourdomain.com The above will generate three files in /opt/postal/config. - postal.yml is the main postal configuration file - signing.key is the private key used to sign various things in Postal - Caddyfile is the configuration for the Caddy web server Open /opt/postal/config/postal.yml and add all the values for DB and other settings. Go through the file and see what else you can edit. At the very least, enter the correct DB details for postal message_db and main_db. Step 5 : Initialize the Postal database and create an admin user postal initialize postal make-user If everything goes well with postal initialize, then celebrate. This is the part where you may face some issues due to DB connection failures. Step 6 : Start running postal # run postal postal start #checking postal status postal status # If you make any config changes in future you can restart postal like so # postal restart Step 7 : Proxy for web traffic To handle web traffic and ensure TLS termination you can use any proxy server of your choice, nginx, traefik , caddy etc. Based on Postal documentation, the following will start up caddy. You can use the compose file below it. Caddy is easy to use and does a lot for you out of the box. Ensure your A records are pointing to your server before running Caddy. docker run -d --name postal-caddy --restart always --network host -v /opt/postal/config/Caddyfile:/etc/caddy/Caddyfile -v /opt/postal/caddy-data:/data caddy Here is a compose file you can use instead of the above docker run command. Name it something like caddy-compose.yaml services: postal-caddy: image: caddy container_name: postal-caddy restart: always network_mode: host volumes: - /opt/postal/config/Caddyfile:/etc/caddy/Caddyfile - /opt/postal/caddy-data:/data You can run it by doing docker compose -f caddy-compose.yaml up -d Now it's time to go to the browser and login. Use the domain, bootstrapped earlier. Add an organization, create server and add a domain. This is done via the UI and it is very straight forward. For every domain you add, ensure to add the DNS records you are provided.

Enable IP Pools

One of the reasons why Postal is great for bulk email sending, is because it allows for sending emails using multiple IPs in a round-robin fashion. Pre-requisites - Ensure the IPs you want to add as part of the pool, are already added to your VPS/server. Every cloud provider has a documentation for adding additional IPs, make sure you follow their guide to add all the IPs to the network. When you run ip a , you should see the IP addresses you intend to use in the pool. Enabling IP pools in the Postal config First step is to enable IP pools settings in the postal configuration, then restart postal. Add the following configuration in the postal.yaml (/opt/postal/config/postal.yml) file to enable pools. If the section postal: , exists, then just add use_ip_pools: true under it. postal: use_ip_pools: true Then restart postal. postal stop && postal start The next step is to go to the postal interface on your browser. A new IP pools link is now visible at the top right corner of your postal dashboard. You can use the IP pools link to add a pool, then assign IP addresses in the pools. A pool could be something like marketing, transactions, billing, general etc. Once the pools are created and IPs assigned to them, you can attach a pool to an organization. This organization can now use the provided IP addresses to send emails. Open up an organization and assign a pool to it. Organizations → choose IPs → choose pools . You can then assign the IP pool to servers from the server's Settings page. You can also use the IP pool to configure IP rules for the organization or server. At any point, if you are lost, look at the Postal documentation. Read the full article

A Guide to Creating APIs for Web Applications

APIs (Application Programming Interfaces) are the backbone of modern web applications, enabling communication between frontend and backend systems, third-party services, and databases. In this guide, we’ll explore how to create APIs, best practices, and tools to use.

1. Understanding APIs in Web Applications

An API allows different software applications to communicate using defined rules. Web APIs specifically enable interaction between a client (frontend) and a server (backend) using protocols like REST, GraphQL, or gRPC.

Types of APIs

RESTful APIs — Uses HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources.

GraphQL APIs — Allows clients to request only the data they need, reducing over-fetching.

gRPC APIs — Uses protocol buffers for high-performance communication, suitable for microservices.

2. Setting Up a REST API: Step-by-Step

Step 1: Choose a Framework

Node.js (Express.js) — Lightweight and popular for JavaScript applications.

Python (Flask/Django) — Flask is simple, while Django provides built-in features.

Java (Spring Boot) — Enterprise-level framework for Java-based APIs.

Step 2: Create a Basic API

Here’s an example of a simple REST API using Express.js (Node.js):javascriptconst express = require('express'); const app = express(); app.use(express.json());let users = [{ id: 1, name: "John Doe" }];app.get('/users', (req, res) => { res.json(users); });app.post('/users', (req, res) => { const user = { id: users.length + 1, name: req.body.name }; users.push(user); res.status(201).json(user); });app.listen(3000, () => console.log('API running on port 3000'));

Step 3: Connect to a Database

APIs often need a database to store and retrieve data. Popular databases include:

SQL Databases (PostgreSQL, MySQL) — Structured data storage.

NoSQL Databases (MongoDB, Firebase) — Unstructured or flexible data storage.

Example of integrating MongoDB using Mongoose in Node.js:javascriptconst mongoose = require('mongoose'); mongoose.connect('mongodb://localhost:27017/mydb', { useNewUrlParser: true, useUnifiedTopology: true });const UserSchema = new mongoose.Schema({ name: String }); const User = mongoose.model('User', UserSchema);app.post('/users', async (req, res) => { const user = new User({ name: req.body.name }); await user.save(); res.status(201).json(user); });

3. Best Practices for API Development

🔹 Use Proper HTTP Methods:

GET – Retrieve data

POST – Create new data

PUT/PATCH – Update existing data

DELETE – Remove data

🔹 Implement Authentication & Authorization

Use JWT (JSON Web Token) or OAuth for securing APIs.

Example of JWT authentication in Express.js:

javascript

const jwt = require('jsonwebtoken'); const token = jwt.sign({ userId: 1 }, 'secretKey', { expiresIn: '1h' });

🔹 Handle Errors Gracefully

Return appropriate status codes (400 for bad requests, 404 for not found, 500 for server errors).

Example:

javascript

app.use((err, req, res, next) => { res.status(500).json({ error: err.message }); });

🔹 Use API Documentation Tools

Swagger or Postman to document and test APIs.

4. Deploying Your API

Once your API is built, deploy it using:

Cloud Platforms: AWS (Lambda, EC2), Google Cloud, Azure.

Serverless Functions: AWS Lambda, Vercel, Firebase Functions.

Containerization: Deploy APIs using Docker and Kubernetes.

Example: Deploying with DockerdockerfileFROM node:14 WORKDIR /app COPY package.json ./ RUN npm install COPY . . CMD ["node", "server.js"] EXPOSE 3000

5. API Testing and Monitoring

Use Postman or Insomnia for testing API requests.

Monitor API Performance with tools like Prometheus, New Relic, or Datadog.

Final Thoughts

Creating APIs for web applications involves careful planning, development, and deployment. Following best practices ensures security, scalability, and efficiency.

What are the challenges faced in selenium automation testing?

While implementing test automation using Selenium, testers might come across several challenges in Selenium automation testing. Some common ones include: 

1. Dynamic Elements 

Issue: Web elements like buttons, links, or input fields to change dynamically (ID/name/location,) between runs of the same test. 

Resolution: To handle these changes, follow stable locators such as XPath, CSS Selectors, and dynamic waits (e.g., WebDriverWait). 

2. Handling Pop-ups and Alerts 

One: It is difficult to deal with various types of pop-ups, such as JavaScript alerts, file upload dialogs, and windows, in different browsers. 

Solution Selenium Native Method provided By switchTo() alert(), switchTo(). It manages operating system windows using JavaRobot commands & 3rd party tools like AutoIT to handle them. 

3. Cross-Browser Compatibility 

Issue: Variability among browsers — Browsers render elements differently and may specially interpret JavaScript. 

Resolution: You should regularly test on different browsers or through Selenium grid and cloud platforms like BrowserStack, making your scripts resilient enough to work across them. 

4. Page Load and Sync Issues 

Issue: Different network conditions would load the web pages at different speeds, which can cause flaky tests if scripts try to interact with elements that are not ready. 

Solution: Use expected waits (for example, WebDriverWait and fluent wait), rather than static sleep timings. 

5. Handling Frames and iFrames 

Issue: It is very difficult to find and operate elements inside the frame or iFrame, as Selenium needs to be switched onto a particular frame before acting on it. 

Solution: Use the switchTo(). The frame() method is used to switch over frame or iFrame before performing activities. 

6. Test Data Management 

Issue: It is hard to control the test data, especially when you have a huge number of tests. Most tests fail because of data dependency, or wrong Data. 

Resolution: Maintain test data in external sources such as Excel, CSV, or DB and ensure unique / refreshed (as per requirement) records for each run. 

7. Maintenance of Test Scripts 

Issue: Test scripts need to be constantly updated, due to modification in UI and functions of the application under test. This leads to higher maintenance efforts. 

Action: Introduce page object model (POM) or other structures to make maintenance easier, by having them in one place for locators and methods. 

8. Captcha and OTP Handling 

Challenge 1: Selenium generally gets interrupted while doing the automation with captcha images and OTP, as these are meant to prevent anonymous activity. 

Solution: Test environments in which Captchas/OTPs are eliminated or APIs invoked to directly read OTPs from the backend allowed by them. 

9. Speed of Execution 

Issue: One reason why Selenium tests might fall slow is the browser interaction overhead. 

Answer: Employ in parallel with Selenium Grid cloud forms, maintain the count of test cases to a minimum, and avoid unnecessary browser operations. 

10. CI/CD integration 

Challenge Three: Selenium testing takes time to integrate as it includes setting up an environment or managing dependencies and this makes the integration of Selenium Testing with Continuous Integration tools like Jenkins a daunting task. 

Done by using Docker containers throwing away the image after each build; this guarantees constant setup and consistent environment as well as sets dependencies up on our CI pipeline. 

11. Poor Support for Non-Web Apps 

Issue: The main problem is that Selenium is made for automating web browsers and it does not support desktop and mobile apps natively. 

Solution: Use other tools like Appium (mobile) or desktop automation tools with selenium for testing Desktop and mobile apps. 

12. Screenshot and Logging 

Issue: It becomes very hard to debug test failure without logging the exact point of break in case proper logs and screenshots are placed at the location where it fails. 

Solution: Use a logging framework (e.g., Log4j) to perform robust logs and, when an error happens use getScreenshotAs() from Selenium 

Conclusion:- 

Although Selenium is a powerful tool and widely used for UI automation of web-based applications, it has its challenges. Dealing with this complexity makes it hard to overcome the challenges of dynamic elements and synchronization problems which results in flaky tests that will increase maintenance efforts. But with the proper approaches including advanced senior locators, dynamic waits, robust test data management, and some of the page object model(pom) frameworks it could be reduced to a great extent. Moreover, making use of parallel execution to synchronize with CI/CD pipelines and complement Selenium's other tools (for handling pop-ups, Captchas, etc )will make the test automation process much more efficient and robust. Selenium automation should be a careful strategy, with the scripts always being updated and improved over time to scale high, reliability in tests.

Automating TYPO3 Installation – A Quick and Easy Guide

Introduction

TYPO3 is a powerful content management system, but installing it manually can be complicated and time-consuming. Thankfully, automation tools like Docker and DDEV allow developers to set up TYPO3 projects with just a few commands. This blog will guide you through automating the TYPO3 installation process, making your workflow faster and easier.

Why Automate TYPO3 Installation?

Manual TYPO3 installation involves multiple steps—downloading files, setting up a database, and configuring the environment. Automating this process helps in: ✅ Saving time on repetitive setups ✅ Reducing errors in installation ✅ Quickly switching between TYPO3 versions

What You Need:

Before you start, make sure you have:

Docker installed and running

DDEV, a tool that simplifies local TYPO3 development

A bash script that automates the installation process

How the Automation Works:

The installation script works as follows:

You run the command:bashCopyEditinstall-typo3 12 myproject.com

The script sets up TYPO3 v12 with a working DDEV environment.

It automatically installs phpMyAdmin and cron jobs to handle scheduled tasks.

A local package directory is created for better project management.

The TYPO3 backend login credentials are set up:

Username: admin

Password: Password1%

Removing a TYPO3 Installation:

If you no longer need a TYPO3 project, you can remove it with a simple command: remove-typo3

This will delete the entire TYPO3 installation and free up space.

Final Thoughts

Automating TYPO3 installation with Docker and DDEV makes development faster and easier. Whether you're a TYPO3 beginner or an experienced developer, this method will save you time and allow you to focus on building websites instead of worrying about setup.
