== Backdoor? ==
According to a tweet by (already deleted, [https://twitter.com/RichDevX/status/504389462496137217 source]), there is a backdoor in XDR Ram that allows the attacker to write to any place in the memory. 16:40, 27 August 2014‎ [[User:Zecoxao]]
 
: without actual tweet hard to discuss... It is in the nature of /XDR/ RAM to be Random Accessable Memory in the first place ;) As long as you stick to that one module at a time. There is no HV/W^X etc on that hardware level (which takes place in the CPU / OS instead) [[User:Euss|Euss]] ([[User talk:Euss|talk]]) 12:13, 27 August 2014 (EDT)

::: According to wikipedia: each chip has a low-speed serial bus used to determine its capabilities and configure its interface. This consists of three shared inputs: a reset line (RST), a serial command input (CMD) and a serial clock (SCK), and serial data in/out lines (SDI and SDO) that are daisy-chained together and eventually connect to a single pin on the memory controller.
