Whiteboard Wednesday: Memory Extraction from SPI Flash Devices

In this week’s Whiteboard Wednesday, Deral Heiland, Research Lead of IoT Technology at Rapid7, walks us through a step-by-step guide to extracting memory or firmware from Serial Peripheral Interface (SPI) flash devices.

was looking for a solution to a different problem, found this video, and learned how to make a previously solved problem more efficient! great stuff!

[@ramakrishnamishra8179]

This was best and simple primer to do it! Loved it

[@code9960]

Awesome video thanks, Deral!

Amazing video, cannot wait to get a shikra and grabing the firmware off my IoT devices

Hi Deral
What to do in case the IC is write protected?
I want to modify the content of the memory dump so extracted and rewrite it back to the IC...Seeking your guidance on this !

[@slave_market]

informative thank you sir 🙂

Serial Outline - that's a new one :)

There are devices that use SPI programmers for adding music or audio to a sound chip via a PC, For the purpose of making a greeting card. Is there any way to extract the music off the chip?
I also have this halloween sound effects box which does have an 8 pin SMD IC chip on it and a larger 16 pin IC. I'd like to extract the sounds from it.

Hello,
I am using Version 1.1.bin. Everything was ok since I tried to change the ssid from pwned to another name. In the same step I also changed the wifi Password and clicked "save".
After that the new ssid is displayed, but when i try to connect, the new password is not accepted. I was very carefully when changing the password and i am sure that i wrote it correctly.
Also the old password "deauther" doesnt work.
I flashed the esp8266 again, hoping that would set everything to default, but after that it Shows the new given ssid again and no Login possible.
Any ideas?

Awesome

Hey I dont know where to look but Im trying to make a key chain that has 2 buttons and a speaker that when you press one button it will say yes ans the other button will say no. Will a w25q32 be able to do 2 buttons and a speaker? I ordered a ATtiny85 first but it only has 8kb storage

[@sonikempire]

Can u connect to these chips with chip still soldered on the board but board not being powered on? But still power it with 3.3V externally?

[@ScHAmPi]

I'm wondering the same, albeit 4 years later :).

Hi - how about 48 pin flash memory (spansion Mfr. No:S29AL032D90TAI040 ) - read and write-programming needed to un brick a firmware issue?? . what would be best hardware+software to use? Any help appreciated

[@javiersalas4168]

what about JEDEC Flash Parameter Tables

[@toddmoore112]

awesome mustache

[@Davysguru]

Noob question: can i use sd card reader for this, hack???

[@vuthu1261]

Beautiful love u.

[@nihildegrasse1700]

Whoa, looks like he use his moustache to flash spi flash chips
