Fresh hacks every day
The Maxim DS2431 1K EEPROM is 1-Wire device that adds storage to a project using a single microcontroller pin. We previously interfaced a 1-wire thermometer, but this EEPROM is slightly different because it draws power directly from the 1-Wire bus. Grab the datasheet (PDF) and follow along while we read and write this simple 1-Wire memory. … [Read more...]
The team from Princeton has released their cold boot attack tools at The Last HOPE. Earlier this year they showed how to recover crypto keys from the memory of a machine that had been powered off. Now they've provided the tools necessary to acquire and play around with your own memory dumps. The bios_memimage tool is written in C and uses PXE to boot the machine and copy the memory. The package … [Read more...]
An article in EETimes suggests that we may see a memristor-based memory prototype in development as soon as 2009. The memristor is claimed by many to be the theorized fourth passive circuit element, linking the fundamental circuit variables of charge and flux. This news may not sound that exciting to most computer geeks, but this new component could usher in a new era of computer memory by forming … [Read more...]
[Rich] over at Securosis takes us through some of his browser paranoia exercises. He uses different browser profiles for different types of web activities. Based on potential risk, various tasks are separated to protect from CSRF attacks and more. Everyday browsing with low risk passwords is done in one. RSS reading with no passwords is done in another. He runs his personal blog in a browser … [Read more...]
