As per the data shared by cybersecurity firm Kaspersky, 3.6 lakh malicious files detected each day on average in 2020. It shows a 5.2 percent of increase in the number of malicious files detected each day from 2019. The Kaspersky Security Bulletin: Statistics of the Year report says cyber crime activities witnessed a major rise in 2020, due to a significant increase in the number of Trojan horses by 40.5 percent which are capable of deleting data and spying.
There is also the presence of backdoors – a specific type of Trojan that controls the infected device. which grew by 23 percent. The report also says that 89.8 percent of the malicious files detected were in the format of Windows PE files. A 27 percent increase in the number of different scripts that were sent through malicious email and websites.
Denis Staforkin, security expert at Kaspersky said, “Over the past year, our detection systems discovered far more new malicious objects than they did in 2019. Due to the pandemic, users from around the world were forced to spend more time on their devices and online. It’s 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, and this will most likely continue going into 2021 as employees continue to work from home and countries implement different restrictions. However, if users take basic security precautions, they can significantly lower their risk of encountering them”.
