The pandemic has increased the number of cyberattacks in many areas. One of the ones that stands out is that of smart home devices, grouped under the name Internet of Things, I. Lights, termostatos, Plugs,… a large number of home devices can now connect to the Internet and this makes them vulnerable to cyberattacks.
ZScaler analysts have examined in their latest study the devices connected to the network during the pandemic period, in which people have been working from home. The report highlights that around 575 millions of information exchanges have occurred and around 300.000 specific attacks on these devices have been blocked, thus giving an increase of 7 times compared to the previous year.
Durante más de un año, la gran mayoría de oficinas ha sido abandonada por sus empleados pero a pesar de ello, este tipo de dispositivos ha seguido utilizando la conexión a Internet, destaca el CISO de Zscaler, Deepen Desai. In addition, apunta que su equipo ha encontrado que un 76% de estos dispositivos, que van desde bombillas a altavoces inteligentes, efectúa sus comunicaciones en texto plano sin cifrar.
Si queremos ver la foto completa, prácticamente la mitad de ataques han ocurrido en Irlanda, con un 48% y le siguen Estados Unidos y China con un 32 and a 14%, respectively. Todos estos ataques provienen mayoritariamente de China, Estados Unidos e India, con un 56, one 19 and a 14%, respectively.
At last, nos gustaría finalizar el artículo con algunas recomendaciones. Primero, habría que conocer qué estamos conectando a internet y cómo lo hace. Then, we should change all the default passwords on our devices. It is also important to keep them updated at all times and, por último, if they can be installed on an isolated network, much better.
