ESET says Russia-linked hackers hid malware traffic in Yggdrasil network

ESET has identified Russia-linked hackers utilizing the decentralized Yggdrasil network to mask malware traffic during a cyberattack targeting a Ukrainian grain company. According to a report published Thursday, this represents the first documented instance of a state-linked hacking group employing the Yggdrasil network for such purposes. Separately, the Traffic Evaluator project emphasizes the importance of network traffic awareness, demonstrating how packet analysis reveals which internet hosts connected devices communicate with and how ISPs harvest data.
