Value written to the EtherRAT resolver contract 0x8b12e09abb2e5130310b24c75b51c8afd85e8223 by operator wallet 0x2dbca26addf031ada655861933d0386a39ea6427 on 2026-03-25, as recorded in the contract's setString events. This is an on-chain observation by this site, not a value carried in published reporting. The contract was found by its identical bytecode and setString event to published EtherRAT resolvers (keccak256 of runtime code 484c7fb94d7084807bf4385d4c7fe9bd768ecb92669c162fac9ab299b28f302e). A TryCloudflare tunnel name written by an operator of the contract; these names are ephemeral and free to create, so the entry records what the implant was pointed at rather than a host likely to be reused. The label rests on Sysdig's attribution of the EtherRAT family; one deployment of the family (The DFIR Report) ended in The Gentlemen ransomware with no nation-state named, so this entry carries low confidence and is not itself a DPRK attribution.
