Shiba Inu users have been warned about a rising threat of Telegram username scams, as reported by Susbarium on September 19, 2025. Scammers are offering large sums for trusted usernames, enabling impersonation and phishing attacks. Users are advised to reject unsolicited offers, verify official accounts, and protect their seed phrases and private keys. Security experts, including Susbarium and Ledger CTO Charles Guillemet, stress the importance of reviewing transactions and using hardware wallets. The crypto community is urged to enable two-step verification and avoid off-platform negotiations to safeguard assets and maintain trust.
