Accordingly, the number of users encountering malware, hidden on devices and mimicking legitimate software, reached 2,402 incidents with 4,110 files distributed as SMB-related software. These figures indicate an increase in attack activity, with an 8% increase compared to the same period last year.
Infection rates in SMB businesses are increasing due to the rise of attacks targeting Microsoft Excel.
According to Kaspersky's latest report, an increasing number of small and medium-sized businesses are becoming targets of cybercriminals. The most common form of attack continues to be Trojans, which, although not capable of self-replication like viruses, can mimic legitimate software. Furthermore, their adaptability and ability to evade cybersecurity tools make them a popular tool for cybercriminals.
Between January and April 2024, Kaspersky recorded a total of 100,465 Trojan attacks, representing a 7% increase compared to the same period in 2023.
Accordingly, Microsoft Excel continues to be the most attacked software in 2024. This is followed by Microsoft Word, and the third most targeted software by criminals is Microsoft PowerPoint and Salesforce.
To obtain research results on threats in SMB businesses, Kaspersky analysts cross-referenced applications such as MS Office, MS Teams, Skype, and many other programs used in SMB workspaces based on Kaspersky Security Network (KSN) telemetry. This method helps Kaspersky determine the prevalence of malware and unwanted software associated with these programs, as well as the number of users affected by these files.
Furthermore, phishing continues to be a threat to SMBs, causing serious consequences for businesses. Employees are constantly receiving familiar-looking links and websites that mimic popular services, business portals, and online banking platforms. Once they log into these services, they inadvertently reveal their usernames and passwords to cybercriminals or trigger pre-planned cyberattacks on the system, such as compromising sensitive information and business security.
"Our technology reveals that the human element continues to be a significant vulnerability for SMBs, partly due to low cybersecurity awareness. Furthermore, the widespread use of Microsoft Excel in office utilities creates an ideal environment for cybercriminals to hide and maliciously alter data in large datasets, then disseminate it widely throughout the organization. Moreover, SMBs often believe they are not targets of cyberattacks, but hackers are very adept at finding any vulnerabilities in the vast network of linked assets they control. Therefore, SMBs should create clear policies regarding access to any company assets and ensure that employees are regularly reminded of the importance of adhering to basic cybersecurity rules," commented Vasily Kolesnikov, a cybersecurity expert at Kaspersky.
