What is DMA attack?
DMA attacks are a particularly powerful class of attacks for any adversary who has compromised firmware locally or remotely on peripheral hardware such as network cards, or who has physical access to a system.
What is remote DMA?
In the same way that DMA allows fast direct access between peripherals and system memory on a device, Remote DMA or RDMA provides similar direct access to memory between devices over Ethernet and other network interconnects. And once again, this direct access to memory can provide an avenue for attack.
Is DMA a powerful attack?
It is important to note that DMA is a powerful technique that does not necessarily require the attacker to have physical access to the device. In fact, data centers and cloud environments can be at the greatest risk for remotely enabled DMA attacks.
Can a XPS 13 7390 be attacked?
We quickly found that the XPS 13 7390 was susceptible to pre-boot DMA attacks. We were able to perform DMA code injection directly over Thunderbolt during the boot process. This closed-chassis DMA attack can be performed considerably faster and with less risk than an open-chassis attack, as an attacker could simply connect to the exposed port of the device without otherwise having to modify the device.
Why Use Remote Access Control?
Deploying remote access control provides a secure connection. It minimizes the risk of data theft or loss and malicious activities since you are controlling the connection, therefore not allowing unknown entities to access private or corporate data.

A DMA Attack Primer
Closed-Chassis DMA Attack – Dell XPS 13
- As part of our ongoing research into firmware attacks, we tested a relatively new device from Dell, the XPS 13 7390 2-in-1. Released in October 2019, the 7390 2-in-1 is the convertible follow-on to Dell’s highly popular XPS 13 laptop. The device we tested was based on Intel’s 10th generation Ice Lake processor. We quickly found that the XPS 13 7390 was susceptible to pre-boot DMA attack…
Vendor Mitigations
- Dell has published a security advisory to address this issue at https://www.dell.com/support/article/SLN319808and has confirmed that all other platforms supporting Thunderbolt have this setting turned off by default.
Open-Chassis DMA Attack – HP Probook 640 G4 with HP Sure Start Gen4
- As part of this same research project, we acquired an HP ProBook 640 G4, designed with enterprise-grade performance, security, and manageability, including HP Sure Start Gen4. Among other capabilities, HP Sure Start incorporates an embedded controller designed to verify the integrity of the BIOS before the CPU executes its first line of code. Although this device was not …
