New malicious files discovered daily grow by 5.7% to 380,000 in 202123 December 2021
In 2021, Kaspersky’s detection systems discovered 380,000 malicious files per day, indicating a 5.7% increase compared to 2020. This growth correlates with the continuous rise in the number of devices used worldwide, among other factors.
Kaspersky’s detection systems discovered an average of 380,000 new malicious files daily over the past 12 months, reflecting growth of 20,000 compared to the previous year. Traditionally, most threats (91%) occurred via WindowsPE files – a file format specific to Windows operating systems. However, in 2021 cybercriminals started spreading threats associated with the Linux operating system more actively than ever before. As a result, the number of detected Linux malware and unwanted software grew by 57%.
More than half (54%) of the threats detected by Kaspersky’s systems comprised unspecified Trojans. While many types of threats reflected a decrease in volume in 2021 compared to 2020, Trojan Droppers grew by 2.24% compared to 2020. This type of malware is particularly dangerous since these programs are designed to deliver other, more sophisticated malware to a victim’s device. There was also a noticeable increase in the number of worms detected (117.5%), with their share reaching 9% – these programs can self-replicate and propagate independently once they breach the system. Lastly, viruses grew by 27%, increasing their share to 10%.
