Russia-linked hackers first to use Yggdrasil network in Ukraine grain firm attack

ESET reports that Russia-linked hackers used the volunteer-run Yggdrasil decentralized network to hide communications during an attack on a Ukrainian grain logistics company, marking the first documented use of this technology by a state-linked group. The claim is based on ESET's analysis, which is credible but not yet independently corroborated. This signals an evolution in state-sponsored cyber tradecraft, potentially complicating attribution and defense.
