In addition, the researchers uncovered evidence of reverse shell deployment designed to collect device and backup information. Confluence and VMWare Horizon are two other products that were extensively. "While z0Miner, JavaX, and some other payloads were downloaded directly by the web shells used for initial compromise, the Jin bots were tied to the use of Sliver, and used the same wallets as Mimo - suggesting these three malware were used by the same actor," the researchers say.
