  • EtherRAT command-and-control domain the operator wrote to the watchlisted resolver contract 0x3f35e6fbe1098f0685137ab81189e891939825af with setString on 2026-03-18, read by this site from the contract's write history. Recorded as the address the implant was pointed at, not as a host this site has observed serving anything. A domain an operator points an implant at can be a compromised legitimate site rather than one it registered.
