Russia-linked hackers use decentralised network in Ukraine cyberattack

Russia-linked hackers used the volunteer-run Yggdrasil network to ⁠conceal ⁠communications during an attack on a Ukrainian grain logistics company, marking the first documented use of the technology by a state-linked hacking group, cybersecurity firm ESET said. The attack culminated in the destruction ‌of data at the company, which forms part ‌of ‌Ukraine's vital agricultural export sector. Agriculture accounted for ‌roughly a fifth of Ukraine's economy and nearly ⁠half its exports before the war, according to research estimates.
