With the 2023 which is now coming to an end, the time for taking stock of a difficult year in the context of the cybersecurity.
The annual report of Kaspersky has highlighted rapidly growing numbers, among which a rather exhaustive figure stands out: during this year, the antivirus just mentioned has detected a total of nearly 125 million malicious files. The analysis, however, goes well beyond this sensational number, examining how Web threats are evolving.
From the research it emerges how Windows remains the preferred environment for cybercriminals. With the’88% of the registered cases, the operating system of Microsoft is confirmed as the main objective.
From the point of view of malware, the most widespread in 2023 continue to be trojan, confirming the trend of recent years. If, however, only the growth rate is calculated, the backdoor are those that have undergone the greatest surge: in 2022 Kaspersky identified one average of 15,000 per day while, during this year, the average has risen to 40.000.
What about malicious files? The cases of PDF e documents various exploited for cyber attacks have grown of 53%. High numbers, which demonstrate once again how the Web is an increasingly less safe place.
Kaspersky: Windows is the most affected operating system, Trojans are the most widespread malware
The data presented by the company is based only on Kaspersky antivirus detections, taking into consideration the months from January a October. If these numbers appear somewhat worrying, it should therefore be considered that this tool represents only a portion of the entire user base who, fortunately, adopt anti-malware tools and similar.
Vladimir Kuskov, Head of Anti-Malware Research at Kaspersky, expressed his concern about the evolution of malware. The techniques and methods for attacking organizations and individual users are in fact updated more and more frequently, making the work of antivirus developers increasingly complicated and frenetic.
For Kuskov, the introduction ofArtificial intelligence has facilitated the work of cybercriminals, lowering the barriers to entry with “new recruits” ready to strengthen the ranks of cybercrime. All this allows, for example, to create messaggi phishing convincing in a very short time.
