Kaspersky, the global cybersecurity and digital privacy company trusted by more than 240,000 clients, recently reported a 5.7% increase in the number of new malicious files discovered daily in 2021. This is equivalent to an average of 380,000 files per day, which is 20,000 more than the daily average in the previous year.
The findings are included in the company’s Kaspersky Security Bulletin (KSB), an annual series of predictions and analytical reports on cybersecurity.
The report indicated that cyber criminals started spreading threats associated with the Linux operating system more actively than ever before, resulting in the growth of Linux malware and unwanted software 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 dangerous because they 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.
Likewise, viruses grew by 27%, increasing their share to 10%.
“Throughout the past year, we discovered 20,000 more malicious files per day compared to the previous year,” said Denis Staforkin, a security expert at Kaspersky. “This was not unexpected – online activity is still at its height due to remote working being adopted worldwide.”
Staforkin continued, “The major shift to online operations also means more devices are being used worldwide. That leads to a wider attack surface and, subsequently, wider exposure to threats.”
To curb rising threats, Starforkin emphasized the importance of digital literacy and keeping abreast of security solutions.
Safety recommendations for individual users:
- Do not download and install applications from untrusted sources
- Do not click on any links from unknown sources or suspicious online advertisements
- Create strong and unique passwords, including a mix of lower-case and upper-case letters, numbers, and punctuation, as well as activating two-factor authentication
- Always install updates. Some of them may contain critical security issue fixes
- Ignore messages asking to disable security systems for office or cybersecurity software
- Use a robust security solution appropriate to your system type and devices, such as Kaspersky Internet Security or Kaspersky Security Cloud. It will tell you which sites shouldn’t be open and protect you from malware
Safety recommendations for organizations:
- Always keep software updated on all the devices you use to prevent attackers from infiltrating your network by exploiting vulnerabilities.
- Establish the practice of using strong passwords to access corporate services. Use multi-factor authentication for access to remote services.
- Choose a proven endpoint security solution such as Kaspersky Endpoint Security for Business that is equipped with behavior-based detection and anomaly control capabilities for effective protection against known and unknown threats.
