Tsundere
Tsundere is an emerging botnet tracked under the name Tsundere and attributed in the provided reporting to the Russian-speaking threat actor "koneko." It was described in reporting titled “Blockchain and Node.js abused by Tsundere: an emerging botnet.” The botnet uses an Ethereum smart contract disguised as an ERC-20 token named "MisakaNetwork" to store and rotate command-and-control addresses on the public blockchain; one reported contract address was 0xa1b40044EBc2794f207D45143Bd82a1B86156c6b. In the cited investigation of exposed MuddyWater infrastructure, a file named reset.ps1 was assessed not to be MuddyWater malware but instead a Tsundere botnet dropper, indicating overlap between the exposed environment and this Russian-speaking cybercrime toolset. A reported Tsundere C2 server at 185.236.25.119 exposed ports 80, 135, 445, 3000, 3001, and 3389. Known alias in the provided content: koneko.
