Con 10 dólares, héroe de 22 años frenó el peor ciberataque de la historia

Un experto en seguridad británico y la firma estadounidense Proofpoint colaboraron para detener el ciberataque global que ha afectado a organismos y empresas de cerca de cien países, ha revelado este sábado el diario The Guardian.

El experto, conocido en las redes sociales con el nombre de MalwareTech, con la ayuda con Darien Huss, de Proofpoint, descubrió un “interruptor” que permitió desactivar el software malicioso que infectó, entre otros, a numerosos equipos del sistema de salud del Reino Unido.

Ambos identificaron un nombre dominio en internet con el que el malware trataba de contactar sin éxito y registraron ese dominio para poder enviar al programa una señal para inhabilitarse. “Me di cuenta de que no estaba registrado y pensé: ‘Creo que lo tengo'”, relató el experto MalwerTech a la revista estadounidense The Daily Beast.

La publicación relata cómo el informático compró el dominio gwea.com por 10,69 dólares (9,77 euros) y redirigió el tráfico a un servidor de Los Ángeles.

“Inmediatamente vimos cinco o seis mil conexiones por segundo”, explicó el experto, que alertó de que “hay un cien por cien de posibilidades de que lanzarán un nuevo ejemplar (de virus)” que podría volver a infectar ordenadores que no estén actualizados.

“Confieso que ignoraba que registrar el dominio pararía el malware hasta después de registrarlo, así que inicialmente fue accidental”, aseguró MalwareTech en Twitter. Este usuario también ha contado en su blog cómo detuvo “accidentalmente” esta oleada mundial de ciberataques.
