C2 hosts this address pointed malware at, newest first. Dates are when the value was written on-chain, and Transaction opens the one that first wrote it; a row without one is a tie a cited report states. A host whose verdict is decoy was written between real values and is not C2. See the EtherHiding Tracker.

Fallback - Aptos: 0x3414a658f13b652f24301e986f9e0079ef506992472c1d5224180340d8105837 → extracts from arguments[0]

Notes:

Aptos account the malware queries when the TRON lookup fails: fallback for TLmj13VL4p6NQ7jpxz8d9uYY6FUKCYatSe. The malware reads the account's latest transaction and takes a BSC transaction hash from payload.arguments[0]. Ransom-ISAC prints some of these as "Aptos Hash" in its indicator table; the code it reproduces passes them to the Aptos accounts API, so they are recorded here as accounts. 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.
