Microsoft Surface devices do not have Thunderbolt or removable RAM for a reason

Microsoft Surface devices do not have Thunderbolt or removable RAM for a reason

The Microsoft Surface Pro 7.

If you're wondering why Microsoft Surface devices do not have Thunderbolt ports or removable RAM, the company now has an official reason. 

A Microsoft employee reportedly revealed the reason during a Surface engineering webinar, which was then leaked on Twitter by @h0x0d. The employee shared that adding Thunderbolt ports or removable RAM can expose the Surface devices to potential attacks. 

“No Surface device has Thunderbolt. Why not? Because that’s a direct memory access port,” explains the Microsoft employee. “If you have a well prepared stick that you can put into the direct memory access port, then you can access the full device in memory and all data that’s stored in memory. We don’t believe, at this moment, that Thunderbolt can deliver the security that’s really needed from the devices.”

The above reason also applies for removable RAM; a hacker can freeze the memory with liquid nitrogen, get the memory out, and access all the data in a specifc reader. 

While The Verge is unable to get a comment from Microsoft on this matter, it is able to verify the authenticity of the presentation. The Verge also claimed that the employee is a Surface technology specialist who has worked in Microsoft for more than 10 years.
