3D Printing storm

I have been printing like crazy recently.

  1. Giant number for my gate, to avoid delivery persons from failing to find the house. They had complained. I just used Blender's text and extruded it with a couple of counter sunk screw holes.
  2. Downloaded a cable clip specifically for the Ender2 V3. It holds the boden tube to the cable array and keeps everything neat. It was flopping and getting dangerously close to catching on something. You are supposed to use cable ties and cut them each time you need access.
  3. A toothpaste holder to track if I have done my teeth in the morning and evening. Also has a toothbrush head holder as I cannot charge my toothbrush in the bathroom and separating the head was always a worry. Why do I need to track brushing my teeth? The medications I am on are confusingly at different times. So, I might do everything other than brush my teeth and then come back unsure if I had or not :D

I like the way all three are me-problems :D

HR cracked

HR sent me an email with a password protected PDF attached with the instructions to use my DOB DDMMYYYY as the password...

and it didn't work :(

I could have just emailed back ... but ... it was more fun to use AI to craft a bash script that used pdfinfo to brute force the password!!

Did it work !!?

NO!

Well, it might have but it was insanely slow, so I switched to John-The-Ripper, which feels like one of oldest bits of software out there.

I did have a lot of faffing about getting the right libraries installed to run the pdf2john.py script. But once that had extracted the hash from my PDF john was off and running.

Eventually it got 96% after 3 hours and found the password!

It was my DOB with some wonky values. Something I had anticipated and I had tried each digit in the password string off by one. The actual value had multiple values wrong and not off by one.
