The majority of malware (54%) was generic trojans, however the company points out that “trojan droppers”, capable of opening doors to other malicious files, grew 2.24% and worms, which can self-replicate and propagate, more than doubled in number (117.5%) among the two years.

how to protect yourself

A series of precautions can reduce the risks of suffering an attack on the internet. One of them is to download files from official sources only. That is, clicking on a link sent by an unknown address, however attractive that “promotion”, almost always results in an attempt to violate the system.

Kaspersky recommends using uppercase and lowercase passwords, numbers, and punctuation, and enabling two-factor authentication. Another important action is to keep the software up to date, both the operating system itself and the programs and applications.

A cybersecurity solution can also be essential, particularly on corporate networks. These protection systems and programs should never be disabled at the request of third parties, as this can be an opportunity for cybercriminals to act.

An AI reveals the opinion of Internet users on vaccination before the pandemic



A few years ago, researchers analyzed several million tweets to study the online user behavior. To do this, they used artificial intelligence able to classify users based on what they have posted.


The experiment was mainly centered on the debates concerning climate change and vaccination. The study had shown that opinions about the vaccine were less uniform than those about the climate.

The data collected on Twitter dates from the period between 2007 and 2016, so it predates COVID-19. However, these records reflect opinion on vaccines during the pre-pandemic period.

An AI programmed to study discussions on Twitter

Several years before COVID-19, a team of researchers from the University of Waterloo analyzed 87 million tweets. The objective of the research was to observe the degree of interactions of individuals and communities online on the two major themes.

“We wanted to look at the two issues of climate change and vaccination side by side. Both questions have social and environmental components, and there is much to learn from this pair of research. »

Madhur Anand, professor of environmental science at the University of Guelph

As part of this study, an artificial intelligence was responsible for categorize millions of tweets. The system has been programmed to decide between users’ posts in favorable categories, unfavorable Where neutral. The use of this AI would also have made it possible toanalyze the degree of interaction between users with opposite feelings.

The arrival of COVID-19 could change the direction of the debates

At the time, the debates around global warming were contrary to those concerning the vaccine. In fact, only 15 to 20% have identified themselves provaccines, against 70% who would have shown little interest. In addition, users with divergent opinions on the subject had only a few interactions.

Nevertheless, with the health crisis, the debates on the vaccine have intensified. Moreover, it is very likely that if the same study were carried out today with data from the last two years, the results could be very different.

“One wonders if these differences in user sentiments and social media echo chambers regarding vaccines created the conditions for a strong polarization of sentiments towards vaccines when COVID-19 vaccines began to be distributed. »
