Cybersecurity researchers have flagged an evolution of the EtherHiding blockchain-based command-and-control (C2) technique that conceals the C2 server IP address inside a made-up destination address of a completely empty Ethereum transfer. The new dead drop resolver approach, observed in two trojanized npm package "bianira-ui" and "fluid-type-ui," has been codenamed NullReceiver by

Researchers at Shandong University have shown a fast new way to pull data off computers that are cut off from every network. The technique, called TrojPix, tweaks on-screen pixels in ways the eye cannot see, so that the video cable carrying them radiates a faint radio signal a nearby receiver can decode.
