In 2020, an average of 360,000 new malicious files was detected by Kaspersky per day\u2014an increase of 5.2% when compared to the previous year. This was influenced mostly by a large growth in the number of <\/strong>Trojans<\/strong><\/a> (malicious files capable of a range of actions, including deleting data and spying) and backdoors (a specific type of Trojan that gives attackers remote control over the infected device): a 40.5% and 23% increase respectively. These were the trends found by the Kaspersky Security Bulletin: Statistics of the Year Report.<\/strong><\/p>\n\n\n\n

Kaspersky\u2019s detection systems discovered an average of 360,000 new malicious files every day over the past 12 months\u201418,000 more than the previous year (a 5.2% increase) and up from 346,000 in 2018. 60.2% of those malicious files were non-specific Trojans. In general, the percent of Trojans detected increased by 40.5% when compared to the previous year. <\/p>\n\n\n\n

There was also a noticeable increase in the number of backdoors detected and worms<\/a> (malicious programs that self-replicate on your system), written on the  VisualBasicScript language and usually belonging to the Dinihou malware family. <\/p>\n\n\n\n

On the decline is adw<\/a>are (programs that bombard you with advertisements), which experienced a 35% decrease compared to 2019. <\/p>\n\n\n\n

The vast majority of malicious files detected (89.80%) occurred via Windows PE files\u2014a file format specific to Windows operating systems. Simultaneously, the number of new malware related to Android operating systems declined by 13.7%. Given that many people were working and studying from home, most likely on computers and laptops, attackers appear to have shifted their focus to these devices. There was also a 27% increase in the number of different scripts\u2014sent via malicious email campaigns or encountered on infected websites, which could, once again, reflect the fact that people spent more time on the Internet and attackers attempted to capitalize on that fact. <\/p>\n\n\n\n

 \u201cOver the past year, our detection systems discovered far more new malicious objects than they did in 2019. Due to the pandemic, users worldwide were forced to spend more time on their devices and online. It\u2019s hard to know whether or not attackers were more active or our solutions detected more malicious files simply because of greater activity. It could be a combination of both. Either way, we have registered a noticeable increase in the number of new malicious files this year. This will most likely continue going into 2021 as employees continue to work from home and implement different restrictions. However, if users take basic security precautions, they can significantly lower their risk of encountering them,\u201d comments Denis Staforkin, a security expert at Kaspersky.<\/p>\n\n\n\n
