El mayor exchange de criptomonedas de Brasil queda fuera de servicio tras un robo de 49 millones de dólares

El mayor exchange de criptomonedas de Brasil ha desconectado su plataforma tras un incidente de seguridad que afectó activos criptográficos por un valor de aproximadamente 49 millones de dólares.

Según informa Valor Econômico, Mercado Bitcoin afirma que ningún cliente ha perdido dinero ni se han filtrado datos, y que ya ha bloqueado 11,2 millones de dólares de esos activos con la ayuda de socios como Tether, Circle, BRL1, Paxos y Chainalysis.

El exchange lo indica en un post en X:

“Hemos identificado y contenido rápidamente un incidente de seguridad en uno de nuestros sistemas esta mañana temprano.”

Inicialmente, el exchange detuvo los depósitos y retiradas mientras sus equipos investigaban, rastreaban los activos y colaboraban con las autoridades.

Más tarde, compartió las direcciones de las carteras destinatarias relacionadas con el incidente en las redes EVM, Bitcoin, Solana, Stellar y Tron para que pudieran ser rastreadas.

La empresa de datos de blockchain Arkham afirma que el atacante sustrajo activos criptográficos por un valor de aproximadamente 46,3 millones de dólares de la plataforma.

La empresa de seguridad Hypernative había señalado anteriormente flujos de salida de fondos por un valor de unos 40 millones de dólares desde carteras que atribuye al exchange.

Paolo Ardoino, CEO de Tether, indica que la empresa emisora de stablecoins ha congelado más de 4,5 millones de USDT relacionados con el incidente.

Mercado Bitcoin declara que mantendrá la plataforma fuera de servicio hasta que pueda reiniciarla de manera segura y compartirá un cronograma de las acciones a través de sus canales oficiales.

También se advierte a los clientes que estén atentos a posibles estafas, indicando que nunca se solicitan contraseñas, códigos de verificación ni frases de recuperación.
