Notes:

BNB Smart Chain transaction whose input field carries an encrypted JavaScript stage that the malware fetches with eth_getTransactionByHash: the BSC transaction pointed to by TXfxHUet9pJVU1BgVkBAbrES4YUc1nGzcG (Payload1 hash 2 in part 2); listed in Ransom-ISAC's part 4 indicator table as a cross-chain pointer target of TXfxHUet9pJVU1BgVkBAbrES4YUc1nGzcG. Recorded from the cited indicator table; this site has not decrypted the calldata. Ransom-ISAC, which calls the technique Cross-Chain TxDataHiding (XCTDH), says the targeting and operational priorities strongly suggest a DPRK-affiliated actor, and its part 4, written with Crystal Intelligence, reports funding traced to addresses involved in other DPRK thefts. The first part of the series rests on infrastructure and targeting rather than on a named cluster, so this entry carries the Contagious Interview label and no UNC cluster.
