The top three threats were malicious families disseminated through various scripts and document formats, accounting for 10% of all detected malicious files.

Kaspersky’s security systems have detected a significant daily increase in malicious files in various document formats such as Microsoft Office, PDF, etc. The number of such files has risen by 53% to approximately 24,000.

The most commonly found type of malware is trojans. This year, there has been a noticeable increase in the use of backdoors, rising from 15,000 detected files per day in 2022 to 40,000 in 2023.

Backdoors are hazardous trojans as they allow attackers to remotely control a victim’s system and perform tasks such as sending, receiving, executing, and deleting files, accessing confidential data, and logging computer activity.

“The cyberthreat landscape continues to evolve, becoming more dangerous year after year. Adversaries continue to develop new malware, techniques, and methods to attack organizations and individuals. The number of vulnerabilities reported is also growing annually, and threat actors including ransomware gangs use them without hesitating. Furthermore, the entry barrier into cybercrime is now being lowered due to the proliferation of AI, which attackers use, for example, to create phishing messages with more convincing texts. In these times, it is essential both for large organizations and for every regular user to embrace reliable security solutions. Kaspersky experts are dedicated to tackling these ever-evolving cyberthreats, ensuring a secure online experience for users every day and providing vital threat intelligence about relevant threats,” comments Vladimir Kuskov, Head of Anti-Malware Research at Kaspersky.
