0xa210e19de57555face122be5cdc57cc0636ddb1c is a smart contract address that one published source reports in connection with EtherHiding activity, which no published source ties to North Korea (DPRK). It is cited here from Chollima Hunter (on-chain observation). The report is dated 2026-04-14.

DPRK link unconfirmed Found by this site's hunt in a chain-wide sweep for the DataUpdated(string,string) event; no published report covers it. The stored values are cryptocurrency-miner configurations, which points to a cryptojacking operation, and nothing ties it to North Korea. The EtherHiding tracker covers every reported EtherHiding contract and wallet, not only North Korean ones, so this value may belong to another actor.

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.
