It’s amazing what you can find inside the RAM on embedded devices using a JTAG! I’m currently dumping the RAM image of an energy usage monitor. So far I’ve seen OpenVPN keys and a few other interesting files still in memory. With any luck I’ll get a copy of /etc/passwd 😉

More DroboPro FS fun
I’ve been playing around with my old DroboPro and in the process managed to frag the uBoot config rendering the unit basically useless as the vxWorks side didn’t boot the special disk applications required for correction function. Â Fortunately I have another Drobo, in this case a Drobo FS. Â I was able to disassemble that (I …
Drobo Pro/FS
After working through it a bit more it appears that the problem is actually in the Drobo Dashboard. Â For some reason it is refusing to show the “Drobo ProFS”. Â I loaded up the 1.8.4 version of the Drobo Dashboard and it sees the unit just fine but doesn’t allow much to be configured. Â Maybe I …

Success!
Time for bed. Â I’ve successfully hacked an app I need for work to do something it is not supposed to do 🙂 Â A little reverse engineering, byte patching and single stepping through machine code and I now have it being quite naughty 🙂
Hopper Disassembler
I’ve been using a new disassembler a lot over the last couple of weeks called Hopper. Â I’m finding it to be well worth the money. Â So much so that I initially purchased it through the Apple App store, and then purchased it again directly from the developer so I could get access to the latest …
