Miles de compañías se ven afectadas por virus cibernético

¿Cómo actúa WannaCry? Infecta la computadora cifrando todos sus archivos y se propaga a otros dispositivos que están conectados a una red local.

Es un software malicioso que al infectar un determinado equipo le da al hacker la capacidad de bloquear una computadora desde una ubicación remota, encriptar todos los archivos y quitarle al usuario el control de toda la información y datos almacenados.

En Rusia se informó que los ordenadores atacados fueron del Ministerio del Interior. La misma concluyó que en los últimos 12 meses, uno de cada tres ataques se debe a temas de seguridad en las empresas.

"Hasta ahora hemos detectado más de 75.000 ataques en 99 países", dijo noche Jakub Kroustek, de la empresa de seguridad Avast.

De esta manera, la Cámara Argentina de Centros de Contacto confirmó que se activaron acciones "reactivas y preventivas" ante los ciberataques informados en Europa, y aseguraron que todas las empresas argentinas que mantienen relación como filiales o proveedoras de españolas han reaccionado a la alerta, activando protocolos y apagando servidores.

"El ataque ha afectado puntualmente a equipos informáticos de trabajadores de varias compañías".

El ataque ha causado estragos, al punto de detener la producción en línea de coches en las plantas de fabricación de Renault, afectar la operación de envíos de Fedex en Estados Unidos o interrumpir el servicio de 48 organizaciones relacionadas a la seguridad social de Reino Unido.

Microsoft reactivó una actualización para ayudar a los usuarios de ciertas versiones de su sistema operativo Windows a enfrentar el ciberataque mundial perpetrado con un virus 'ransomware' denominado 'Wannacry'.

"A diferencia de la mayoría de los ataques, este virus se difunde principalmente por infección directa, más que puramente por correo electrónico", dijo Lance Cottrell, responsable del grupo de tecnología de Estados Unidos Ntrepid.

"Puede propagarse sin que nadie abra un correo electrónico o haga clic en un enlace", agregó.

El exanalista de la NSA Edward Snowden, reclamado por la Justicia estadounidense por alta traición, criticó profusamente a la agencia de seguridad desde su cuenta de Twitter.

Esto es importante porque consideran que este tipo de ataques continuará, afectando no sólo a empresas sino también a personas comunes. Pero para las computadoras que ya están afectadas esta medida no surte efecto. El WannaCry aprovechó una vulnerabilidad de Windows para propagarse.
