Kaspersky’s Security Bulletin: Statistics of the Year Report for 2023 reveals alarming trends in cybercrime [3]. This report highlights the increase in malicious files being released by cybercriminals and the growing use of desktop files to spread malware. It also sheds light on the prevalence of Trojans and the rise in backdoor attacks. Additionally, the report emphasizes the continuous development of new malware and techniques by adversaries [3], as well as the growing number of reported vulnerabilities [3].


According to Kaspersky’s report [2], cybercriminals released an average of 411,000 malicious files per day in 2023 [2], marking a 3% increase from the previous year [2] [3]. Of the 125 million files detected, 24,000 were identified as malicious desktop files [2] [3], such as Microsoft Office and PDF documents [2] [3], representing a 53% increase from 2022 [2]. This rise can be attributed to the use of phishing PDF files designed to steal data from potential victims [2].

Trojans remain the most widespread type of malware [1] [3], with a significant increase in the use of backdoors [3]. Backdoors provide attackers with remote control over a victim’s system [3], enabling them to carry out various tasks and harvest confidential data [3]. In 2023, 40,000 backdoor files were detected per day, compared to 15,000 in 2022 [1].

The report also highlights the continuous development of new malware [3], techniques [3], and methods by adversaries [3]. It emphasizes the lowering entry barrier into cybercrime due to the proliferation of AI [3], which attackers use to create more convincing phishing messages [3]. The report covers the period from November 2022 to October 2023 and is based on data obtained from users who consented to sharing it with Kaspersky’s Security Network (KSN) [3].


The findings of this report have significant implications for cybersecurity. The increase in malicious files and the use of desktop files to spread malware highlight the need for robust security measures. Organizations and individuals must remain vigilant and implement strong security protocols to protect against these evolving threats.

The rise in backdoor attacks also underscores the importance of proactive defense strategies. It is crucial to regularly update and patch systems, as well as educate users about the risks of phishing and social engineering tactics.

Furthermore, the continuous development of new malware and techniques by adversaries calls for ongoing research and innovation in the field of cybersecurity. Collaboration between security experts, organizations, and law enforcement agencies is essential to stay one step ahead of cybercriminals.

In conclusion, the Kaspersky report serves as a wake-up call to the increasing sophistication and prevalence of cyber threats. It is imperative that individuals and organizations take proactive measures to safeguard their digital assets and protect against the ever-evolving landscape of cybercrime.
