I've been building PRISM - a self-hosted OSINT toolkit you run yourself instead of pasting investigation targets into someone else's web service.

Give it a domain, IP, email, phone, or username and it runs 22+ modules in parallel into one dashboard: WHOIS, DNS, crt.sh subdomains, GeoIP, threat intel (Shodan/VirusTotal/AbuseIPDB/Censys), breach data, username search across 3000+ sites (Blackbird + Maigret), dark-web mirror checks, and more. Results come with an entity graph, a GeoIP map, an OPSEC exposure score (0–100), and HTML/PDF/CSV/Markdown exports.

14 of the 22 modules work with zero API keys (missing keys degrade gracefully instead of erroring).

Stack: FastAPI + Next.js 14, runs with one docker compose up. MIT licensed.

Demo: https://getprism.su/ Github: https://github.com/NovaCode37/Prism-platform

Built it solo - feedback welcome, especially on which modules you'd want added.

So I have an interest in self hosting things in the future (nextcloud, chatmail), but for now I'm scared of opening my network to attacks, and also I don't have a network right now I just hotspot from my phone when needed and torrent things at my friend's house.

That said how would I go about using this? I'm guessing something to do with docker or porteus (maybe? The other one that wasn't vulnerable to that recent thing), then when I want to check out X website I just "spin up the docker container" (still not 100% what that means but I've heard the verbiage), hotspot the pc (for now), and run it through the program? Am I understanding that right?

Sorry I'm so green, gotta start somewhere! I feel like a grandma calling an Xbox a "Nintendo" haha.

Yeah, this project is built as a docker container. The repo has instructions on starting the container. You should watch a few introductory videos on Docker so you understand the concepts and basic usage.

Once it's started, the machine that docker is running on will be serving a website that acts as the application. If you're running docker on your desktop you can then open a web browser and go to http://localhost:8080/ and you will see something that looks like the demo link above.

This doesn't expose it to the Internet. If you're running this on a home LAN with a router between you and the ISP's modem (or the ISP's modem is a router/AP) then only computers connected to your network will be able to access it. You would have to go to your router's administration console and specifically forward a port for that service so that people on the Internet could get past your modem.

Awesome thanks for all the help and info, I'll definitely check it out! I think this will be a nice step to help teach me these concepts and get me to the other projects!

Sorry I’m so green, gotta start somewhere!

We all started at green. No shame.

So, yes OP is using Docker. Once you install Docker on your server, you 'spin up' the docker container using the Docker compose file:

https://github.com/NovaCode37/Prism-platform/blob/main/docker-compose.yml

....and the associated .env file that houses all your environmental variables:

https://github.com/NovaCode37/Prism-platform/blob/main/.env.example

Awesome, thank you for the help/info! This seems like a good first step, I'll try it out!

[–] irmadlad@lemmy.world 3 points 4 days ago (1 children)

Give it a go man. What's the worst that can happen? .....you have to drop back and do some studyin'. That's pretty much how I learn. Read, Do, Fuck it up ad nauseam until it clicks, then I write that shit down.

[–] ArcaneSlime@lemmy.dbzer0.com 3 points 4 days ago (1 children)

Same here lol, I will for sure!

[–] FauxLiving@lemmy.world 1 points 3 days ago (1 children)

Putting yourself into the position of trying to solve a practical problem is the best way to learn.

If you fail completely, you can always restore your system and try again (you have a backup, right?)

[–] ArcaneSlime@lemmy.dbzer0.com 2 points 3 days ago

Yes, but I'd still prefer not to have to spend the like ~2h reinstalling and replacing my files.

That said this seems like a pretty low stakes trial which is why I'm looking at it first. Worst case a reboot (or recovery through live booting) should fix most issues, I think, if I understand correctly. I don't plan to autostart the docker container so if it fucks my system up a reboot should put me back to normal if starting it breaks my sys right?

I do have some old laptops and an unopened router waiting for me to figure out openWRT. I could install some linux OS (deb?) on one of those and use that for docker, get off my ass and install openWRT on the router, and then use that to connect both devices (and I'd have to figure out which to hotspot but that is easy), if that'd be significantly safer for my daily driver. Then I'd have to figure out how to point my browser to that too though.

Start with the documentation. Docker has a great introductory section that teaches you the basics.

https://docs.docker.com/get-started/introduction/ (the pushing your image part is not that important, the rest is)

Running a project that does things you don't know is not the best thing to learn. Learning is done by going through the basics first, not immediately firing docker compose, which is one step above pure docker.

Thank you! I'll check out the docker docs before I try spinning this up as my first trial run!
