Information for Reverse Engineering Day
There is a hackspace project to reverse engineer the chinese laser cutter software to discover its secrets, and allow us to make something a little bit better. So we are planning on having a day on the 15th of Jan dedicated to all things reverse engineering. It will be a day of code hacking and prodding the binary files generated by the laser cutter software.
There will be also be a couple of talks, for those that wish. I'm doing a beginner's guide to patching with Ollydbg, and Mark is doing something on the differences between the low-level guts of windows and linux.
Things you will Need
If you want to play along.
Will's Demo- Windows system or wine + Ollydbg
Bring food: There will be some number of bacon butties for lunch. Other things will need to be brought along. We have a grill and microwave but no hob
For jasper's sofware:
- Mercurial to acquire it from his server
- hg clone http://pointless.net/hg/mpc6515 *localfilename*
Communication and file storage
Tentative:
#laz0rs on freenode
File storage: lovelace@lovelace:/home/lovelace/RElaz0r
There are some files on: laz0rs (hackspaceremote/hackspace)
To do
All these are doable at your own initiative,
Tricking the software to think it has a laser cutter attached
The laser software won't generate .mol files unless it thinks it has a laser cutter attached. Possible ways to do this include:
- Emulate the the usb device. No known way to do this, so research it. Either hardware or software. Info here on software
- Look at the code. If it just asks windows what USB devices there are attached, make it ask for things already attached.
Programmatic problems
- Automate .mol file analysis - automol
- Research dxf handling
Useful non-reverse engineering stuff
- We could do with setting up the old dirty room for presentations, so we can have presentations later on.
- Connecting laz0rs (the machine that runs the laser cutter) to the network- Connected!
- Get some laser cutter
Tickets
To be sorted out. We probably won't need any.
When?
A 1 day hacking thing on 15th of January
Where?
Saturday
- At some point : Will's (eb4890) talk : How to patch software with minimal ASM knowledge
- At some other point : Mark's (ms7821) talk
For who?
Anyone that knows a bit about the internals of a computer (file formats or machine archs)!
Possibly attending:
- Ciarán

- Morris
- Tasos
- Sam
- Jasper
- Mark
- Will

How much?
There is no charge HOWEVER the space survives on donations and member subscriptions. We recommend a voluntary donation of £X for the day.
