According to data collected by Kaspersky, there were 20,000 more files per day compared to 2020.
In 2021, detection systems from cybersecurity company Kaspersky detected nearly 380,000 new malicious files per day, an increase of 5.7% from 2020, which corresponds to 20,000 additional malicious files per day. This growth is attributed, among other things, to the continued increase in the number of devices around the world.
According to Kaspersky , the main target remains Windows with 91% of detections, but threats against Linux are also up by almost 57% compared to last year.
Trojans stand out among the most common threats, with 54% of detections. Kaspersky systems have also detected an increase in ” trojan droppers “, injectors that install other malicious software on a victim’s computer or phone. Computer worms increased by 117.5%, and traditional viruses by 27%.
“ In 2021, we detected 20,000 more malicious files per day than the previous year,” explains Giampaolo Dedola, senior security researcher at Kaspersky’s GReAT. “It’s a pretty predictable scenario, as online activities have mushroomed following the adoption of remote working around the world. In addition, the number of devices in use has also increased globally, leading to a widening of the attack surface exposed to threats. Therefore, it is extremely important for today’s users to improve their digital literacy and keep their security solutions up to date . “
Adopt good online habits
To avoid unpleasant surprises in the face of this growing number of threats, Kaspersky recommends adopting best practices when browsing online. The cybersecurity company therefore recommends against downloading applications from untrusted sources, not clicking on links from unknown sources or suspicious online advertisements, creating strong and unique passwords and install software updates regularly.
