IT security in the home office: How to tell if your devices have been hacked

Not all companies were prepared for the rapid switch to the home office. Today, one day after the relaxation of the COVID-19 measures by the Federal Council, many companies are talking about continuing their changed way of working and increasingly letting their employees work in a home office. Regardless of whether in the office or home office; security should not be sacrificed. In this blog post, you'll learn how to tell if your devices have been hacked and what you can do to secure them.

Trend Micro is an international provider of server, network and endpoint security software and services with a 30-year vision of making the world safe for the exchange of digital information. The company has been recognized as a global leader in server security since 2010.

Smart Home Network (SHN) Shows Significant Increase in Infections and Attacks on Systems and Networked Devices

In their Smart Home Network (SHN), Trend Micro found a significant increase in attacks on remote systems and networked devices. The analysis below shows a comparison of the months of December 2018, January 2019, February 2019 and March 2019 with the months of December 2019, January 2020, February 2020 and March 2020, clearly showing that the number of incoming infections and attack attempts on desktops and laptops, for example, has increased by nearly 450%.

Infections and attacks without obvious signs: How to recognize symptoms

Especially in the last few months, the number of attacks with coronavirus-related messages also increased. Some malicious routines do not show obvious signs of infection or intrusion, and some symptoms become visible only after certain user actions. Still, users can easily find out if their devices have been hacked or infected with malware. Trend Micro has created a flyer for this purpose.
