Russian cybersecurity agency Kaspersky attributed the assaults “with a excessive diploma of confidence” to a China-linked risk actor tracked by Proofpoint as TA428, citing overlaps in techniques, strategies, and procedures (TTPs).

TA428, additionally tracked beneath the names Bronze Dudley, Temp.Hex, and Vicious Panda, has a historical past of placing entities in Ukraine, Russia, Belarus, and Mongolia. It is believed to share connections with one other hacking group known as Mustang Panda (aka Bronze President).
