In 2021, Kaspersky's detection system found 380,000 malicious files every day, representing an increase of 5.7 percent compared to 2020. This growth is in line with the significant increase in the number of devices used worldwide. 54 percent of the threats detected by Kaspersky systems consist of unknown Trojans. Trojan Droppers grew by 2.24 percent compared to 2020. This type of malware is very dangerous because this program is designed to deliver other, more sophisticated malware to the user's device. There was also an increase in the number of worms detected by around 117.5 percent, with the figure reaching 9 percent – these programs are able to self-replicate and propagate independently once they break into the system. Lastly, the virus experienced a 27 percent increase with the share growing to 10 percent.
"Over the past year, we discovered 20,000 more malicious files every day than the previous year. This was not unexpected – online activity is still high as remote work is adopted worldwide," said Denis Staforkin, security expert at Kaspersky,
He continued, the big shift to online operations also means more devices are used around the world. That leads to a wider attack surface and, subsequently, wider threat exposure.
"Therefore, increasing digital literacy and updating security solutions are two very crucial tasks for today's users," he explained.
Trojan Droppers malware is considered very dangerous because it can send other, more sophisticated malware to the device. The spread of this malicious file is also a result of the increasing number of activities on the network. The more activities that are carried out online or online, the more devices are used. The more devices connected to the internet, the wider the threats and attacks. The statistical report is part of the Kaspersky Security Bulletin (KSB)-a series of annual forecasts and analytical reports on important changes in the world of cybersecurity.
To stay protected, Kaspersky also recommends the following to users:
1. Don't download and install apps from untrusted sources
2. Do not click on any links from unknown sources or suspicious online advertisements.
3. Create a strong and unique password, including a mix of lowercase and uppercase letters, numbers, and punctuation, and enable two-factor authentication.
4. Always install updates. Some of them may contain fixes for critical security issues.
5. Ignore messages asking to disable security systems for office software or cybersecurity.
6. Use a reliable security solution that suits your system type and device, such as Kaspersky Internet Security or Kaspersky Security Cloud. This will tell you which sites should not be opened and protect you from malware.
