banIP - OpenWRT IP List Blocker

So I host a HoneyPot to test whether how many attacks I get per day and what security measures are able to block it. And I started with Snort3 in IDS mode which allowed to detect malicious activity. After I switched to IPS, I noticed that while miscellaneous attacks had

Home Assistant for Home IoT

I generally prefer OSS / self-hosted solutions, but this one was pushed for a serious need. I've BSNL as my ISP, which works mostly fine, but having high latency while trying to turn on a bulb or an appliance is just annoying. Not to mention that "Sorry, I'm unable to do

Some malware from my Honeypot

So I've been running my HoneyPot for many months now, and I do analysis on some samples from time to time. Following are 2 interesting scripts. While one is clearly a tool to demonstrate an attack, now being used in the wild, the other one is a simple port scanner

LED Patterns on Raspberry Pi

I use a lot of Raspberry Pis (4B, 3B, 3A, Zero W, etc) and I use them mostly headless. And while I do have a monitoring setup, I always thought that it would be nicer if I could map the default LEDs to something more useful. And guess what, it

Folding @ Home on TX2

Let me clarify first that this post is not about running GPU enabled folding. For that, some hardware enablement is missing, and thus it'll be really hard to port it, though I may attempt that in future. For CPU performance, TX2 packs decent power, specially with 2 Denver Cores, 4

TX2 Hashing Performance

I recently got 3 TX2(s) donated to me by my friend Sri Krishna Acharya. I did flash it using a comprehensive tutorial provided by him plus slight modifications using an old Macbook Pro running Ubuntu 18.04 (so many NVIDIA quirks here, that this deserves it own blog post)

PLC4x Server Docker Build

Recently I was working on PLC4X and needed to use the tools provided under PLC4J in a Dockerfile. At the time of writing this, the tagged release v0.10.0 fails to build the Dockerfile present in the root of repository. So I built a gist based on some quickly

Onion Omega as a Fan Controller

Final setup, up close.I’m a really big fan of passive cooling rather than active cooling. In fact, as much as possible, I also prefer air cooling over water cooling. Not that I like to run my chips hot, it’s just that I don’t like the noise

HoneyPot running off a Pi Zero W

This tiny guy has seen more attacks than Spartans!I had a Pi Zero W lying around my stuff. My original aim was to run a camera on top of it, but it seemed that Pi 3 handled the video processing much better than this tiny guy, so it was
