Ransomware (¿seguro que tu empresa no está en peligro?)

/en , , , /por

Lamentablemente, nos estamos acostumbrando a ver noticias constantes de ciberataques desde hace ya demasiado tiempo. Parece que la gente tomó conciencia del problema tras el ataque hace unos meses del ransomware WannaCry gracias a su alta repercusión sobre Telefónica, los centros NHS del Reino Unido y otras organizaciones de todo el mundo (de hecho, las ofertas de empleo se triplicaron en la bandeja de entrada de LinkedIn…).

Es evidente que la amenaza planteada por los ciberdelincuentes está en constante evolución, ya que casi a diario se lanzan nuevos tipos de malware cada vez más inteligentes. De hecho, desde entonces hemos visto múltiples ataques a gran escala en Europa, paralizando los sistemas de información sin discreción.

Todo el espectro de pymes y grandes empresas han sido víctimas de los brotes de WannaCry, de hecho hemos visto como empresas de toda Europa fueron atacadas por un ataque ransomware conocido como «Bad Rabbit».

¿Pero esto pasa mucho?

Es habitual pensar que son las empresas más grandes con marcas conocidas las que están más expuestas a estos ataques, ya que poseen una gran cantidad de datos, lo que podría ser un objetivo claro para los ciberdelincuentes. Pero en realidad las empresas más pequeñas son más vulnerables a los ciberataques, ya que no cuentan con los recursos, tecnología y formación necesarios para prevenirlos.

El informe sobre el estado global de seguridad de la información de PwC indica que las empresas tienen que desembolsar un promedio de 980.000 € cada año como resultado de violaciones de seguridad cibernética.

Con menos recursos, muchas PYMES corren el riesgo de fracasar si no hacen más para protegerse.

Para hacernos una idea, una encuesta de violaciones de seguridad de la empresa EY indicaba que una cuarta parte de las empresas se ven afectadas por una violación de la seguridad cibernética cada mes. No debemos tomarlo como un dato exacto, pero debería servir como una señal de advertencia para las empresas tanto grandes como pequeñas.

¿Cómo me protejo?

A las PYMES no les queda más remedio que aumentar el presupuesto de defensa de seguridad cibernética, pero mientras eso ocurre, al menos deberían pensar en:

  • Asegurarse de haber instalado software antivirus y antimalware en todos los dispositivos de la organización.
  • Adquirir software de forma legal y, por supuesto, asegurarse de instalar regularmente cada actualización.
  • Teniendo en cuenta que la gran mayoría de los ciberataques son el resultado de un error humano, asegurarse de capacitar a su personal sobre cómo evitar que el negocio sea vulnerable a los ataques.
  • Echar un vistazo a los consejos de SecurityInside.info para PYMES sin dinero.

La mejor opción es emplear expertos

Las empresas que no lo tengan, deberían considerar la contratación de profesionales que tengan la experiencia para defenderse de estos ataques. Hay un número creciente de empresas a las que pueden subcontratar, en caso de que no tengan los fondos para contratar a un Responsable de Seguridad.

En cualquier caso, está claro que el problema está ahí y ha venido para quedarse. Como empresa o PYME no puedes quedarte esperando, el momento de actuar es ahora.
