There&#x27;s a discussion in r&#x2F;netsec right now about The Evil Maid problem. Looking at the datasheet for a common eeprom (24c256 <a href="http:&#x2F;&#x2F;www.techdesign.be&#x2F;projects&#x2F;datasheet&#x2F;24LC256.pdf" rel="nofollow">http:&#x2F;&#x2F;www.techdesign.be&#x2F;projects&#x2F;datasheet&#x2F;24LC256.pdf</a>), the write protect pin is active high, and has an internal pull-down to GND. For a motherboard that has a physical write-protect or something like that, it&#x27;d be relatively straightforward for the Evil Maid to cut the WP pin to the eeprom to re-enable writes to it.<p>That makes me said. If it were the other way around (pull to VCC to enable writes), you&#x27;d at least need to add a pretty obvious bodge wire to the WP pin to enable writes.
