This one is for all the people who buy a router, set it up according to the default settings, and never look at it again. Unfortunately, default settings aren't really optimized to keep us safe and secure. Instead, they're designed to make the product work out-of-the-box for as many people as possible.
With CISA 2015 set to expire in September 2026, Congress has an opportunity to extend the statute beyond cyber to cover AI-related threats and mitigations.
Any time I recommend software to a friend, there is always an inevitable question: How much does it cost? The quality isn't necessarily the discerning factor—no one wants to pay for something if it isn't necessary. That makes free, open-source tools very easy to recommend to most people without a moment's hesitation.
Some things just lie on the surface, while others take time to find. In OSINT, finding the right data often means digging deep. Before you reach a conclusion, there must be solid evidence to support it, and data acquisition is always the most time consuming part of this process. The success of your investigation depends on how well you can find information and connect the dots.
OpenPlanter can automate part of this process.
OpenPlanter
Essentially, OpenPlanter is a recursive language model investigation agent. It ingests different kinds of data, which can be corporate registries, campaign finance records, government contracts and more. It then resolves entities across them and surfaces connections through evidence-based analysis. You can also use it to build profiles of individuals based on publicly available information.
OpenPlanter has both a desktop GUI and a terminal interface. The second one is more convenient.
Setting Up
The setup process is quick. We just need to create a Python environment that will host the needed libraries.
kali > git clone https://github.com/ShinMegamiBoson/OpenPlanter.git
kali > cd OpenPlanter
kali > python3 -m venv venv; source venv/bin/activate
kali > pip install -e .
Once it’s done, we need to give it our API keys.
To make web searches, OpenPlanter needs the Exa API. Exa is cheap to use and gives free credits for new accounts, so you don’t have to pay upfront. OpenRouter API is also needed to run the tool. OpenRouter has free AI models, but there is a daily usage limit. Make an account there and get your free API key.
To configure keys, run this command and paste them:
kali > openplanter-agent --configure-keys
At this point, you can use the tool.
Using OpenPlanter with OpenRouter
The daily API usage limit is enough to run a couple of basic tests, like the one below.
OpenPlanter will use Exa API key to find information. Without Exa, it burns tokens faster and gives incomplete results.
Normally, the tool saves the results in a text file in the current directory, but it doesn’t always happen. Be careful and make sure you don’t lose anything.
Here is our first report.
To make things more interesting, we asked it to find a complete list of Tatneft executives. Tatneft is one of the largest oil and gas companies in Russia.
The report was well organized, but all this information is readily available on the internet, due to the size of the Russian company.
When it was asked to find more information on a specific person from the list above, it struggled to find much and ended up with some generic data and a wrong social media account. Well, maybe that person is hard to find, so we gave it a second chance and picked a unique name from the same list: Nail Ulfatovich Maganov.
kali > openplanter-agent --task "Find as much information as you can on Nail Ulfatovich Maganov who works at Tatneft. If possible, find his Vkontakte, phone number, address, email and check if his email has been in data leaks. Save the results in a text file" --provider openrouter --model openrouter/free
The results can be seen below. OpenPlanter did find his LinkedIn account and extracted information from various places.
It also found OpenSanctions records associated with Nail Maganov.
But he is a well known figure in Russia. What about regular employees at a large Russian company? We will use Sibur for this example. Founded in 1995, it’s Russia’s largest petrochemical company.
We tried two individuals. During the first attempt, the tool didn’t find the correct person. After the second attempt with a different employee, it gave the results.
It found Svetlana’s position (Head of HR). This information was in her LinkedIn account. The rest of the information deserves further validation. Keep in mind, Russia has undergone a massive data blackout, systematically dismantling its open data and public statistics infrastructure. No wonder it’s hard to find things there.
Using OpenPlanter with Ollama – Locally
OpenPlanter’s own docs push toward frontier models (GPT-5.2, Claude Opus 4.6, Cerebras Qwen3-235B), because the whole process is quite demanding. Small local models will be noticeably weaker. But we still gave it a try. The first model was Qwen3:0.6B and its first attempt didn’t produce any results. After the second attempt, it found recent vulnerabilities that Windows had.
We also tried it with Qwen3:4b, but it produced absolutely irrelevant data in its response.
We didn’t stop here and tried it again. The results were still irrelevant. Instead of making a report on Mikhail Karisalov (CEO of Sibur) it spoke about something else.
Using OpenPlanter with Ollama – Remote Servers
If you decide to rent a server with good hardware to test other models, don’t waste your time on it. We tried various models, but none of them worked well. OpenPlanter calls a model, the model replies and then it fails. The output can be seen on the screen.
Here is an example with Qwen3.6:27b. Qwen3.6:35b had the same issue.
We also tried Ornith:35B.
These models support thinking and tooling, but they can’t really do much in this case.
Terminal Interface
It’s also important to mention that there are two ways you can use OpenPlanter in the terminal. So far, you’ve seen only one. If you’re more comfortable with a chat interface, you can use the second option.
kali > openplanter-agent --provider openrouter --model openrouter/free
Here you run your prompts and tweak the tool using the available commands.
Summary
After testing the tool in various ways, we came to the conclusion that it works reliably only with OpenRouter. That’s what gave us the best results. The developers also push towards frontier models or OpenRouter. The whole process of investigation relies heavily on the Exa API. Using it with Ollama models hosted externally (VPS) will not work, as it fails silently even if you select a supported AI model.
The tool might confuse people, especially if their names are common and their social media profiles are empty. Everything it finds deserves validation. Occasionally, it may check the results, marking them HIGH, MEDIUM or LOW depending on its confidence. It doesn’t always do it, but this can be fixed if the prompt explicitly asks for it. Most importantly, OpenPlanter can still save you time.

Using a Raspberry Pi board with Pi OS is a great way to jump into cybersecurity. You don’t need a lot of fancy gear to get started. Just hook it up to a TV, grab a keyboard and mouse, connect to the internet, and you’re all set with a solid system to explore Linux, programming, and hacking.
In this article, we’ll walk through how to install Raspberry Pi OS Desktop on a Raspberry Pi 4 and check out all the cool tools and features it has to offer. Let’s get rolling!
Step #1: What Is Raspberry Pi OS?
Raspberry Pi OS is the official operating system for Raspberry Pi single-board computers. It was launched back in July 2012 under the name Raspbian, which combines Raspberry Pi and Debian. The OS was created to give early users a stable Linux environment that’s tailored to the hardware’s simpler specifications.
There are three different versions of Raspberry Pi OS, each aimed at different users. The Desktop edition is the most beginner-friendly, featuring the PIXEL (Pi Improved Xwindow Environment Lightweight) desktop environment and popular apps like Chromium, and VLC. This version, requiring at least 32 GB of storage.
Raspberry Pi OS Full includes the desktop and all recommended software. It’s got everything from the regular desktop edition and some additional tools.
The Lite version is perfect for folks who prefer the command line to a graphical desktop. It’s great for servers, headless apps, and projects that need to be light on resources, giving savvy users the flexibility to tweak things just the way they like.
This article focuses on the Desktop edition, the one most new users will download first, and a perfect starting point for exploring what Raspberry Pi can do.
Step #2: Installing Raspberry Pi OS
Installing Raspberry Pi OS is pretty straightforward. First, make sure you have a Raspberry Pi, preferably models 3, 4, 5, 400, or 500 if you want the desktop version. You’ll also need a microSD card of at least 32 GB, a computer to set up the SD card, a micro-HDMI cable, and a monitor. The newer Raspberry Pi 4 and 5 use micro-HDMI, while the older models need full-size HDMI. Don’t forget about a keyboard, a mouse, and a power supply.
To install the OS on the microSD card, use the Raspberry Pi Imager. It is the official tool for creating the OS image and handles everything from downloading to writing and verifying in a single app. If you’re on Linux, open up your terminal and type:
sudo apt install rpi-imager
Once it’s running, you’ll see a screen that looks like what’s shown below.
Click on ‘Raspberry Pi Device’ and pick your model so Imager shows only the OS versions that work with your hardware.
Next, tap on ‘Operating System’.
If you’re new to this, go for ‘Raspberry Pi OS (64-bit)’ at the top since that’s the standard Desktop edition. If you want the Full edition with extra features, just scroll down to ‘Raspberry Pi OS (other)’ and pick ‘Raspberry Pi OS Full’.
After that, plug your microSD card into your computer’s card reader. Hit ‘Storage’ and select your card, making sure you’ve got the right one, since Imager will wipe everything on it. Then, click ‘Save’, then ‘Write’. Imager will download the latest OS image or use one you already have, write it to the card, and check that everything went smoothly.
Finally, once Imager gives you the green light, safely eject the card and boot into your Raspberry Pi.
Step #3: First Boot
Insert the prepared microSD card, connect the display using HDMI, plug in your USB keyboard and mouse, and then connect the power supply. The Raspberry Pi will turn on automatically when you power it up; there’s usually no separate power button on most models.
Then, the setup wizard will guide you through a few easy steps. You’ll set up your location and keyboard layout, create a new username and password to replace the default ones, connect to Wi-Fi, and you can even check for software updates before diving into the desktop.
Eventually, you’ll see a desktop that looks something like this:
The top panel has quick-access icons for the tools you use most, such as the file manager, web browser, and terminal. Click on the leftmost icon to open the application menu, which sorts all your installed software into easy categories like Programming and Internet.
By default, a limited number of apps are installed, but you can easily install additional ones through GUI app installers or the terminal.
Step #4: Key Features and Benefits
Raspberry Pi OS is different from regular Linux distributions because it’s made specifically for Raspberry Pi hardware. Everything, from the kernel to the GPU drivers, is tuned to get the best performance out of the Pi’s ARM processor and VideoCore GPU. The packages in the Raspberry Pi OS repository are compiled with specific optimizations that you won’t find in standard ARM versions of Debian or Ubuntu.
Another great thing about Raspberry Pi OS is that it’s designed to use as little memory as possible from the start. The PIXEL desktop environment, along with some basic background services, uses only about 300–400 MB of RAM at boot, leaving plenty of memory for your applications.
And finally, Raspberry Pi OS is completely free to download, install, and use with no license fees or subscription costs.
Summary
Raspberry Pi OS Desktop isn’t just a lightweight Linux version made for some weird hardware. It’s actually built specifically for the unique features and limitations of Raspberry Pi devices. You can really see this design approach in everything, from how efficiently the system runs to how well the hardware works together and even how clear the documentation is.

Anthropic said it stopped multiple attempts by scientists this year to use its technology for research that could help develop biological weapons, as experts increasingly fear the threat that AI poses to public safety.
The startup gave five examples of times actors “circumvented controls” and made other efforts to “obfuscate” the purpose of their research to dodge safeguards. The cases involved some users in nations that it prohibits from accessing its models, which include Russia, China, and Iran.
“We hope that by sharing these examples, we spark a conversation within the AI industry and with governments about emerging biological risks and how best to counter them,” Anthropic said in a report about efforts to use its models for malicious activity.
Imagine this: you need to keep tabs on a sketchy person who may be involved in fraud. You’ve got some info about them and access to a laptop, ready to dive into your investigation. But as you start digging, you realize your system is missing the right tools for an OSINT investigation. Sure, you could set everything up on Kali Linux or Parrot OS, but that could take hours.
That’s where Tsurugi Linux comes in. In this article, we’ll break down what Tsurugi Linux is, how to get it installed, and what cool features it brings to the table for OSINT investigations. Let’s get rolling!
What is Tsurugi Linux
Many newcomers to open-source intelligence often turn to Kali Linux or Parrot OS as their first specialized distributions, and both are effective tools. However, neither was specifically designed for OSINT purposes. Kali Linux, for instance, is primarily an offensive penetration-testing platform. While it includes some OSINT utilities, its main focus is on exploitation rather than investigation. This is where Tsurugi Linux comes in.
Tsurugi Linux is a free and open-source Linux distribution specifically tailored for incident response and OSINT investigations. Its name, inspired by a Japanese double-bladed sword, reflects its dual emphasis on active intelligence gathering and passive forensic analysis. Tsurugi addresses the challenge of consolidating and curating over 300 specialized tools, thereby saving users the tedious process of installing and configuring each tool individually on a generic system. Instead, Tsurugi provides a pre-packaged, user-friendly environment organized by investigative categories, allowing users to become productive in just hours rather than days.
The Three Flavors of Tsurugi
Before downloading anything, it’s important to understand that Tsurugi is available in three distinct forms, each serving a specific purpose. Tsurugi Linux LAB is the full 64-bit distribution that we will focus on in this article. It includes the complete toolkit and is designed to be installed on a dedicated machine or run in a virtual machine for hands-on analysis and OSINT investigation.
Tsurugi Acquire is a lighter 32-bit version that contains only the essential tools needed for live disk acquisition.
Finally, BENTO is a portable forensics toolkit that you can carry with you and run directly from a USB device, allowing you to conduct live investigations on machines that cannot be taken away.
For getting started purposes, Tsurugi Linux LAB is your target, and you can find the latest ISO image on the official project website at tsurugi-linux.org.
How to Install Tsurugi Linux
In this demonstration, I will install Tsurugi Linux on VirtualBox. To get started, we need to download the latest ISO image from the website and create a new virtual machine based on it.
It is recommended to allocate at least 4 gigabytes of RAM and 60 gigabytes of disk space during the creation process. Once this is done, you can boot the machine. A desktop like the one shown below will welcome you.
First Look
When you boot for the first time, you will see the MATE desktop environment. The taskbar at the top offers quick access to files, an application launcher, a web browser, and a terminal emulator named Terminator.
When you open the Applications menu, you will notice a typical range of categories. Like most distributions, it includes programs for internet browsing, programming, office tasks, various media players, and other standard software that is unlikely to surprise anyone. However, our main focus is on the first item in the menu, labeled TSURUGI.
The top-level categories include OSINT, Memory Forensics, Malware Analysis, Network Analysis, and others. We will not delve into specific tools here; some have been covered in previous articles, and we will address others that haven’t been discussed yet, provided they warrant our attention.
The Tsurugi Browser
Tsurugi Linux ships with a well-known version of the Firefox browser, preinstalled with extensions.
Let’s take a look at some of them.
Tampermonkey is a browser extension that enhances your browsing experience by allowing you to run userscripts on websites. Userscripts are small programs that modify page layouts, add or remove features, and automate actions to personalize your web experience.
DNSlytics lets you retrieve information about a domain, including WHOIS data, DNS records, and more.
NoScript is a browser extension that enhances online security and privacy by blocking JavaScript, Flash, Java, and other potentially harmful content on websites, only allowing execution from sites you explicitly trust.
Additional Features of Tsurugi Linux
The developers of Tsurugi Linux have worked hard to ensure that the operating system is as versatile as possible, making it suitable for a wide range of situations. To achieve this, they have included a vast array of utilities. Notably, they have highlighted OSINT (Open Source Intelligence) as a distinct category that has received special attention.
A dedicated OSINT profile has been introduced, and you can activate it by selecting the OSINT Switcher on the desktop or in the menu. Once enabled, most sections unrelated to OSINT will be removed from the menu, leaving only the relevant options you might need. Additionally, the wallpaper will change to provide a visual indicator of the active profile, ensuring you won’t confuse it with others.
Another valuable feature is the Write Blocker. This is an extra layer of protection against any malicious activity. The external storage device, such as a USB flash drive, will only be accessible in “read-only” mode when connected. To enable writing, select the TSURUGI device unlocker on the desktop. Then, in the window that opens, select the desired device and click “Unlock.”
Summary
Tsurugi Linux is a great choice for beginners starting with OSINT or digital forensics. It provides a friendly and well-equipped environment. While it won’t make you an expert right away, it will help you learn OSINT more quickly.
