I have often wondered if you could exploit a monitor over the DDC bus sending i2c commands. There have just got to be memory corruption bugs in the display controller code.
They probably also typically have some flash memory, so perhaps one could permanently reprogram a monitor after the exploit?
- gardaani 6y agoCould monitors be malicious and exploit vulnerabilities in computers by sending corrupted data over the DDC bus? The crazy thing is that computers send +5V over the DDC bus to the monitor so that they are able to read data even if the monitor is powered off and not connected to the mains! So, simply connecting something to the computer's display port could be enough.
- Zenbit_UX 6y agoThere's already at least one exploit Ive heard of in which the monitor was the attack vector and was used to selectively alter screen pixels.
- blep-arsh 6y agoYes. Dell U2414 (afair) could be updated via DDC and the firmware could draw over the input image.
