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.

Notes:

Ethereum contract that EtherRAT reads to find its command-and-control server, listed in Atos's appendix as created 2025-12-20 with 4 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(0x4f1dd066b832af641b5f08537a5b0fc0b329d5ec) 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.
