I've analyzed the situation with DMA, and what frustrates me is that its effectiveness is entirely dependent on firmware limitations. To remain truly undetected, a device cannot be directly registered within the system. In the long run, software-based firmware is also problematic, as AV/anti-cheat systems will detect behavioral patterns rather than the actual code.
This led me to consider alternative extraction methods. A DMA card might not even be necessary since its primary function is reading data and forwarding it to a KM-box or fuser. Instead of relying on direct hardware interfaces, wouldn't it be possible to extract memory data using electromagnetic side-channel analysis? Processors and memory modules emit detectable electromagnetic radiation during normal operation, and with a highly sensitive near-field probe or software-defined radio (SDR), it should be feasible to capture and reconstruct memory access patterns in real time.
By analyzing the fluctuations in emitted signals from RAM and the CPU, it may be possible to infer memory contents without ever interacting with the system directly. With proper machine learning models, specific data structures—such as ESP locations or player coordinates—could be reconstructed from observed frequency patterns. This would allow real-time memory extraction completely wirelessly, bypassing direct hardware detection mechanisms like IOMMU or firmware integrity checks.
If a fully undetectable data extraction method existed, the primary challenges would be data processing speed and insertion. While electromagnetic extraction provides a covert way to read memory, writing back to memory for live manipulation remains a challenge. One potential insertion vector could involve exploiting wireless peripherals, such as a Logitech mouse, using principles similar to CVE-2019-13052/3. This could allow injection of modified inputs or aim adjustments without modifying game memory directly, complementing the passive extraction method.
With advancements in RF analysis and AI-driven signal processing, electromagnetic memory extraction represents a promising path toward undetectable real-time data access.
What do you guys think, is it a time-wasting project or is it worth creating an alfa?
