    Notes:

    SHA-256 of a deobfuscated DEV#POPPER.JS RAT variant that Ransom-ISAC recovered from BSC transaction 0x1a4272be3c516faea9093f5c2fadadb620cfe8bfbd50e22008847e6056fd91b9 (file 011025_0x1a4272be3c516faea9093f5c2fadadb620cfe8bfbd50e22008847e6056fd91b9_FINAL.txt). Ransom-ISAC prints 20 of more than 70 such hashes in the post and puts the rest in its GitHub repository for part 4, which this site has not mirrored. 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.
