BNB Smart Chain transaction whose input field carries an encrypted JavaScript stage that the malware fetches with eth_getTransactionByHash: named in the file name of a deobfuscated DEV#POPPER.JS RAT variant in Ransom-ISAC's part 4 indicator table (091025_0x828f00daa9fa68b36d2f2380f3fdc27265c53417ef01660b5421ea1125fad2de_FINAL.txt), which the post lists among payload transactions from wallet 0x9bc1355344b54dedf3e44296916ed15653844509. 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.
