HaHa on Crimping Tools And The Cost Of Being Cheap.

At the time it was 4x the speed of comparable chips made by companies like Intel and Motorola that had a decade or more of history, and a huge staff full of PhDs. It’s impressive the ARM was created by a team of 2 or 3 people in Cambridge, their first CPU, as an improvement for the BBC Micro.
Either the room’s just not that dusty (certainly not a clean-room, no masks on the staff), or they can cope with whatever rate of failures they get. They manipulate the tiny, rice-grain sized ARM MCU into the casing, along with the flash itself, using a tool that looks a lot like a wooden chopstick with a notch cut in the end. HAD did a nice article a while back about a factory that makes SD cards. And because it’s arguable which has the most developed and mature Linux, ARM or x86.īut that’s just a guess. Realistically the CPU’s almost certainly an ARM, because what else is there, and because that’s what a lot of normal storage-only SD cards use.
I dunno but something makes me think there’s a lot of flash. Posted in hardware, Linux Hacks Tagged busybox, wi-fi Post navigation

In the end he got the card to connect a bash to his computer so he could launch every command he wanted.Īs it was not enough, even discovered an easy way to find the current password of the card. He just had to make the card download another busybox to use all the commands that were originally disabled in the card’s Linux. Therefore, the password “admin echo haxx > /tmp/hi.txt #” could create a hi.txt text file.įrom there things got easy. His second attempt was a success: found that the user set password is directly entered in a Linux shell command. He first thought he had found a way to make the embedded Linux launch user provided scripts and execute commands by making a special HTTP POST request… which failed due to a small technicality. From there he was able to see if any of the poorly written Perl scripts had security holes… and got more than he bargained for. His clear and detailed write-up begins with explaining how a simple trick allowed him to browse through the card’s file system, which (as he guessed correctly) is running busybox. It allows him to transfer his pictures to any WiFi-enabled device in a matter of seconds.Īs he suspected that some kind of Linux was running on it, he began to see if he could get a root access on it… and succeeded. Is a recent and proud owner of a Transcend WiFi SD Card.
