Following up on my previous blogpost, I got some people asking to clarify how to connect the Analog CMOS to the ESP32 glitcher so I listened to them. I hope this helps everyone trying to reproduce the results!

Gabriel Gonzalez - Cyber Security · Fault Injection III: Connecting the MAXIM4619 - Gabriel Gonzalez - Cyber SecurityIn my previous post, I detailed some tests into fault injection techniques on the nRF52 family experimenting with crowbar circuits, and ultimately being surprised by the effects of an analog CMOS switch, the MAXIM4619. After observing its higher overvoltage and ringing effects compared to a traditional crowbar circuit, many of you reached out asking how […]

Currently trying to solder probes to a mainboard's RAM DIMM connectors to try memory fault injection. Soldering 100+ wires is a huge pain, would anyone know of an existing interface/PCB with pogo pins/something that could make my life simpler?

Or are there tricks to batch-solder such a quantity of small wires?

Great talk by Aedan Cullen (@aedancullen) at #38c3 on breaking security on the #RP2350 by glitching the OTP VDD.

I expect the bus between the state machine and OTP is like Wishbone or M68K and has a request and an acknowledge, and the data is latched on the ACK. No ACK? Guard word stays in the latch.

The fault injection library (PicoGlitcher, Chipwhisper etc) was just updated with the results of me playing around with my PicoGlitcher yesterday evening. This info comes from actual glitches against a so-far unnamed IoT device based on the STM32F412.

Summary:

1) No, it's not realistic to glitch ReadMemory to read out the internal flash from these devices with the known methods.

2) Still fun though and why not study the v3.1 bootloader intensely?

:twitter:​ finally seems to be flat-lining, trying out this new mastodon thing...

#introduction, for peeps I've not met prior via my bird app handle @ntpopgetdope. I'm a vulnerability researcher that's worked in the industry professionally for >4yrs

My background stems from an obsession with #windowsinternals & the vastly underrated 'HAL.dll'. These days I'm into baseband vuln research working on obscure hardware, architectures & attacks. Love chatting about all things:
#fpga #uefi #baseband #faultinjection #openhardware #embeddedelectronics #pcbdesign and #cats !

Currently with the @InterruptLabs crew, a boutique vulnerability research & exploit development firm in the UK.
