Electromagnetic (EM) side-channel leakage and injection are typically treated as distinct physical phenomena, threatening data confidentiality and integrity respectively.

This work investigates how EM injection can be used to amplify side-channel leakage that is otherwise infeasible. We introduce a novel framework for Injection-Induced EM Side Channels to enable integrated, closed-loop EM security analysis. Our theoretical modeling and experimental measurements reveal that nonlinear hardware components, such as ubiquitous amplifiers, analog-to-digital converters, and power converters, can modulate secret electrical signals onto an injected EM carrier and thus upconvert low-frequency secrets into measurable EM emissions. By tuning the injection frequency and amplitude, adversaries gain the ability to actively shape the effective spectrum and entropy of the resulting leakage.

We design InjectEave attack and demonstrate eavesdropping on the audio played through wired and wireless headphones from up to 30 m away with accessible RF equipment, as well as in through-wall scenarios, and characterize injection-induced EM leakage of other low-frequency secrets such as power consumption of smart home devices and analog sensor inputs.

Case studies further demonstrate how the proposed techniques enable closed-loop eavesdropping and manipulation of landline-phone conversations. Finally, we analyze the broader security challenges and mitigations.

The military is searching protected medical records to find transgender troops who have tried to continue serving amid the Trump administration’s ban on trans Americans in uniform, multiple sources tell Federal News Network.

Commanders around the world have started receiving notices that members of their units are violating Pentagon policy, and are being instructed to begin the separation process. The sweep is believed to have outed several hundred active-duty and reserve troops, including service academy and Reserve Officer Training Corps cadets, over the past two months, according to the trans advocacy nonprofit SPARTA Pride and Priya Rashid, an attorney with the National Institute of Military Justice.

Hi! So I'm considering...maybe having an NPU or something similar to be hooked to my proxmox server, which runs in a mini PC. It's a EliteDesk 800 micro form factor. It has a Core i5 8500 CPU, which at the moment of purchase was good enough for live encoding HEVC video on Jellyfin...that was my main concern back then. But I'd like to consider the possibility of hooking maybe some docker instances or other containers to some local-only AI acceleration. Is there any NPU or cheap GPU I could hook on USB to this proxmox server to run? Has it been done before?

Thanks!
