Conta do Twitter do Ubuntu é comprometida em golpe de criptomoedas

07 de maio de 2026

Reportado por IA

A conta oficial do Ubuntu no Twitter publicou um tweet, agora excluído, promovendo um falso agente de IA que direcionava os usuários para um golpe de criptomoedas. O incidente ocorre após um ataque DDoS de cinco dias aos serviços web da Canonical, encerrado no início deste mês.

O tweet, que apareceu algumas horas antes da publicação em 7 de maio, anunciava um agente de IA chamado Numbat, construído na blockchain Solana. A postagem utilizou a marca Ubuntu, incluindo referências ao codinome Noble Numbat do Ubuntu 24.04, e trazia um link para o site ai-ubuntu.com. A página imitava fielmente o design da Canonical e solicitava que os visitantes conectassem uma carteira de criptomoedas após clicarem em botões rotulados como Verificar elegibilidade ou Explorar IA do Ubuntu.
