When you connect to the Internet, the Internet connects to you

Perhaps it seems clear from the title, but such a statement entails consequences that require our attention. Everyone understands the concept of the Internet and the opportunities provided by the interconnection of systems throughout the planet, ‘a new world within your reach’. However, littleattention is paid to the fact that this connection goes both ways, and the ramifications this entails. In this article we explore the different problems that arise from being online.

When we connect something to this huge network in order to obtain certain functionalities or services remotely, we must be aware of the ramifications and the elements that may be visible from the outside.

About bots

Not everything that happens online is the result of human activity, as a lot of it is produced by robots (bots). If we were to analyse everything that goes through the router to give us access to the Internet, we would see that much of it comes from these bots. When a new device connects to the router to access the Internet, the bots will attempt to connect to the device as well.

Real case

One such case of a network of zombie computers (or botnet) was that of ‘Mirai’. For those unfamiliar with the story, it launched one of the most massive attacks to date, which significantly affected or left most of the main websites without access to the Internet. This network then took advantage of the lack of security measures in Internet of Things (IoT) devices to control them, as they were unprotected and online.

Vulnerabilities

If our vulnerable devices are in the European Union or contain data of EU citizens, the consequences can be even greater. On top of the risk of one of our devices being compromised, it may also result in sanctions for not complying with the New General Data Protection Regulation (GDPR).

Conclusion

Any element accessible from the Internet is exposed to a series of risks that should not be underestimated. It is essential to be aware of the fact that, if we connect something to the Internet, the Internet also connects to this item, and with it, the bots that patrol the network.
