0x22f96d61cf118efabc7c5bf3384734fad2f6ead4 is a smart contract address that 3 published sources report in connection with EtherHiding / UNC5342 and unclustered DPRK activity, which public reporting attributes to North Korea (DPRK). It is cited here from Atos Threat Research Center and Sysdig. The earliest of those reports is dated 2025-12-08 and the most recent 2026-04-14.

On-chain links

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.

Write transactions

Every transaction that wrote a value to this contract, newest first, as read from Etherscan on 2026-10-20. Values are shown as the operator wrote them; an encrypted one has not been decrypted.

  Notes:

  Ethereum contract that EtherRAT reads to find its command-and-control server, listed in Atos's appendix as created 2025-12-05 with 9 setString calls when the appendix was compiled. It stores a mapping from operator wallet to URL: the operator writes the C2 with setString(string) and the implant reads it with getString(address) (selector 0x7d434425). On 2026-10-03 getString(0xe941a9b283006f5163ee6b01c1f23aa5951c4c8d) against a public Ethereum node returned a URL, confirming the contract has this shape; the stored values are not recorded here because operators park the resolver on well-known domains between sessions. Atos names no actor of its own: it repeats Sysdig's link between EtherRAT and the DPRK Contagious Interview tooling and notes code overlap with a tool eSentire attributed to an Iranian group, so this entry is filed under the unattributed DPRK label.
