How the scam operates.
O domínio xn--mytherwallet-cok.com é um nome de domínio internacionalizado que, quando renderizado pela maioria dos navegadores, parece visualmente idêntico ao de um conhecido serviço de carteira Ethereum de autocustódia. O operador explora uma falha documentada na exibição de punycode: um caractere Unicode no rótulo é indistinguível de seu equivalente em ASCII no tamanho normal de leitura. O site quase certamente apresenta uma interface de carteira completa, reproduzindo a identidade visual e o layout do serviço legítimo com fidelidade suficiente para passar por uma inspeção superficial.
As vítimas geralmente chegam por e-mails de phishing, malvertising ou links em redes sociais que exibem a forma Unicode do domínio, ocultando sua codificação em punycode. Uma vez na página, a solicitação central é inserir uma seed phrase, chave privada ou arquivo keystore, apresentada como acesso ou recuperação rotineiros da carteira. Essas credenciais são coletadas no lado do servidor. Como as chaves privadas do Ethereum e as seed phrases BIP-39 concedem acesso incondicional aos ativos on-chain, um único envio é suficiente para que o operador esvazie a carteira por completo.
A fraude costuma passar despercebida até que a carteira da vítima já tenha sido esvaziada. A descoberta, quando ocorre, normalmente acontece quando um usuário atento examina a barra de endereços do navegador com cuidado suficiente para notar o prefixo punycode ou um caractere sutilmente deformado no rótulo. Nesse ponto, os fundos em geral já se foram: as transações em blockchain são irreversíveis, a carteira é não custodial por concepção e não há intermediário em posição de congelar ou recuperar a transferência.
Red flags we documented.
- 01Punycode Homograph DomainThe xn-- prefix identifies an internationalised domain name encoding non-ASCII characters. This technique is used to construct addresses that appear visually identical to legitimate services in browser rendering. Its presence here, combined with close phonetic similarity to a well-known Ethereum wallet brand, strongly indicates deliberate impersonation rather than coincidental naming.
- 02Seed Phrase and Private Key SolicitationAny platform that requests a user's seed phrase, private key, or keystore file is operating outside normal security practice. Legitimate non-custodial wallet interfaces do not require these credentials to be transmitted over a network connection. Soliciting them is the defining mechanic of credential-harvesting operations targeting self-custody wallet holders.
- 03CryptoScamDB Blacklist ConfirmationThe domain appears in the CryptoScamDB community blacklist, an independent open-source repository of confirmed malicious addresses curated by the blockchain security community. Inclusion is based on submitted evidence of fraudulent activity and carries a confirmed-scam classification.
- 04No Verifiable Operator IdentityOperations of this type typically use privacy-shielded domain registration, offshore or anonymous hosting, and short domain lifespans. The absence of verifiable operator identity, physical address, or regulatory registration means victims have no formal recourse channel and investigators face significant attribution barriers.
- 05Irreversibility of Losses as a Design FeatureThe choice of a non-custodial Ethereum wallet as the impersonation target is deliberate. Once credentials are harvested and funds transferred on-chain, the transaction cannot be reversed by any third party. This structural irreversibility is not incidental; it is why credential-harvesting operations consistently target self-custody wallet users rather than exchange account holders.
What you can do now.
Open a free 24-hour case assessment with CryptoLeek +
Tell us what happened. A senior analyst reads your file within 24 hours and replies with an honest yes/no/conditional on recovery. The assessment is free. If we cannot recover the funds we say so plainly, including which (free) regulator channel you should use instead. If we accept the case, we open a numbered case file and issue a written quote for a flat investigation retainer before any work begins, scoped to case complexity, the jurisdictions involved, and the on-chain trail.
Trace your funds on-chain with our analysts +
We trace stolen crypto across BTC, ETH, EVM L2s, Solana, Tron, and major stablecoins using the same toolchain as regulators and tier-1 exchange compliance teams. The output is a forensic report anchored to specific transaction hashes and block heights, the evidence that exchanges, payment processors, and counsel actually act on. Recovery starts here.
Recover with counsel where civil action makes sense +
Where the trace lands in a jurisdiction with cooperative banks and courts, we coordinate with bar-licensed counsel in our 40+ jurisdiction network for civil action and asset-freezing orders (Mareva-style). Counsel bill you directly; the CryptoLeek investigation retainer is independent of counsel fees. The outcome is funds released back to your nominated wallet or bank account.
