0xe26c57b7fa8de030238b0a71b3d063397ac127d3 is a smart contract address that 4 published sources report in connection with EtherHiding / UNC5342, unclustered DPRK and Lazarus Group activity, which public reporting attributes to North Korea (DPRK). It is cited here from Hokage Vanguard, Sysdig, Atos Threat Research Center and e Sentire. The earliest of those reports is dated 2026-03-25 and the most recent 2026-05-22.

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.

    Notes:

    Ethereum contract that EtherRAT reads to find its command-and-control server. It stores a mapping from operator wallet to URL: the operator writes the current C2 with setString(string), and the implant reads it back with getString(address) (selector 0x7d434425) through a read-only eth_call that leaves no transaction. Hokage Vanguard reported the contract and its operator wallet and attributes the activity to Lazarus; Sysdig, which first described EtherRAT, attributes the implant to DPRK without naming a cluster, and this entry follows the narrower attribution. The checker on this site reads the operator's current value and the full write history on every run, so a rotation shows up as a change.
