    Fake 'human verification' bookmarklet hijacks Fomo account, drains about $48K from embedded wallet

    A Fomo user clicked a project website link on a token page and landed on a phishing site that asked them to drag an icon to the bookmarks bar and click it three times as a 'human verification'. The bookmark ran on the logged-in Fomo page and took the Privy login tokens and wallet data from browser storage, and about $48,000 (mostly USDC) was moved out. The victim never connected a wallet, signed anything or typed a seed phrase, and had no two-factor login enabled. Fomo users who ran any such bookmark should revoke sessions from a trusted device, turn on MFA and move funds.

    Trader loses over $200K from two SIGMA Telegram bot wallets in apparent private-key leak

    On 11 May 2026 a crypto trader lost over $200,000 across Ethereum, Base and BSC from two wallets created by the SIGMA Telegram trading bot; the largest losses were about $125,000 in POD on Base and $21,000 in FHE on BSC. An on-chain analyst said the drain used the private keys directly, with no token approval involved, while the victim's other wallets were untouched. The cause is unconfirmed; suggestions include fake CAPTCHA bots in Telegram, infostealer malware or a device compromise. Users of bot-generated wallets should keep balances small and never run 'verification' steps a Telegram bot asks for.
