Hi everybody...

After a discussion with a friend of mine, I argued that it was
possible to change the behaviour of a firmware, so that an attacker
could put a backdoor inside, for instance :S...

Perhaps I spoke a bit quickly, 'cause now I feel a bit lost in
modifying the firmware :(.

Basically, every access point proposes you to update its firmware...
Most of the fime, these firmware are sold in a *.bin format. After
having tried to search for relevant strings in the bin, disassembling
it and loosing time, I'm still at the same point :(.

Do you have any experience in firmware modification ? Do you know in
which language firwares are written ? Maybe tryin' a decompilation
could help me...

Thanks a lot

Norbert

Some time ago I found this pdf document about hacking embedded devices.
http://www.blackhat.com/presentations/bh-europe-06/bh-eu-06-Jack.pdf

Hope that this help's you.
